- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
- The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users. We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors. You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
- To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. You must make sure that they, too, receive
-or can get the source code. And you must show them these terms so they
-know their rights.
-
- Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
- For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
- Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so. This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software. The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable. Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products. If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
- Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary. To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS
-
- 0. Definitions.
-
- "This License" refers to version 3 of the GNU General Public License.
-
- "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
- "The Program" refers to any copyrightable work licensed under this
-License. Each licensee is addressed as "you". "Licensees" and
-"recipients" may be individuals or organizations.
-
- To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy. The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
- A "covered work" means either the unmodified Program or a work based
-on the Program.
-
- To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
- To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies. Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
- An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License. If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
- 1. Source Code.
-
- The "source code" for a work means the preferred form of the work
-for making modifications to it. "Object code" means any non-source
-form of a work.
-
- A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
- The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form. A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
- The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities. However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work. For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
- The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
- The Corresponding Source for a work in source code form is that
-same work.
-
- 2. Basic Permissions.
-
- All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met. This License explicitly affirms your unlimited
-permission to run the unmodified Program. The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work. This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
- You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force. You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright. Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
- Conveying under any other circumstances is permitted solely under
-the conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-
- 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
- No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
- When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
- 4. Conveying Verbatim Copies.
-
- You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
- You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
- 5. Conveying Modified Source Versions.
-
- You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
- a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.
-
- b) The work must carry prominent notices stating that it is
- released under this License and any conditions added under section
- 7. This requirement modifies the requirement in section 4 to
- "keep intact all notices".
-
- c) You must license the entire work, as a whole, under this
- License to anyone who comes into possession of a copy. This
- License will therefore apply, along with any applicable section 7
- additional terms, to the whole of the work, and all its parts,
- regardless of how they are packaged. This License gives no
- permission to license the work in any other way, but it does not
- invalidate such permission if you have separately received it.
-
- d) If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your
- work need not make them do so.
-
- A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit. Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
- 6. Conveying Non-Source Forms.
-
- You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
- a) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by the
- Corresponding Source fixed on a durable physical medium
- customarily used for software interchange.
-
- b) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by a
- written offer, valid for at least three years and valid for as
- long as you offer spare parts or customer support for that product
- model, to give anyone who possesses the object code either (1) a
- copy of the Corresponding Source for all the software in the
- product that is covered by this License, on a durable physical
- medium customarily used for software interchange, for a price no
- more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the
- Corresponding Source from a network server at no charge.
-
- c) Convey individual copies of the object code with a copy of the
- written offer to provide the Corresponding Source. This
- alternative is allowed only occasionally and noncommercially, and
- only if you received the object code with such an offer, in accord
- with subsection 6b.
-
- d) Convey the object code by offering access from a designated
- place (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to
- copy the object code is a network server, the Corresponding Source
- may be on a different server (operated by you or a third party)
- that supports equivalent copying facilities, provided you maintain
- clear directions next to the object code saying where to find the
- Corresponding Source. Regardless of what server hosts the
- Corresponding Source, you remain obligated to ensure that it is
- available for as long as needed to satisfy these requirements.
-
- e) Convey the object code using peer-to-peer transmission, provided
- you inform other peers where the object code and Corresponding
- Source of the work are being offered to the general public at no
- charge under subsection 6d.
-
- A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
- A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling. In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage. For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product. A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
- "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source. The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
- If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information. But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
- The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed. Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
- Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
- 7. Additional Terms.
-
- "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law. If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
- When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it. (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.) You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
- Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
- a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- b) Requiring preservation of specified reasonable legal notices or
- author attributions in that material or in the Appropriate Legal
- Notices displayed by works containing it; or
-
- c) Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
-
- d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
-
- e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- f) Requiring indemnification of licensors and authors of that
- material by anyone who conveys the material (or modified versions of
- it) with contractual assumptions of liability to the recipient, for
- any liability that these contractual assumptions directly impose on
- those licensors and authors.
-
- All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10. If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term. If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
- If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
- Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
- 8. Termination.
-
- You may not propagate or modify a covered work except as expressly
-provided under this License. Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
- However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
- Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
- 9. Acceptance Not Required for Having Copies.
-
- You are not required to accept this License in order to receive or
-run a copy of the Program. Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance. However,
-nothing other than this License grants you permission to propagate or
-modify any covered work. These actions infringe copyright if you do
-not accept this License. Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
- 10. Automatic Licensing of Downstream Recipients.
-
- Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License. You are not responsible
-for enforcing compliance by third parties with this License.
-
- An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations. If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
- You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License. For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
- 11. Patents.
-
- A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based. The
-work thus licensed is called the contributor's "contributor version".
-
- A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version. For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
- Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
- In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement). To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
- If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients. "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
- If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
- A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License. You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
- Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
- 12. No Surrender of Others' Freedom.
-
- If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all. For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
- 13. Use with the GNU Affero General Public License.
-
- Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work. The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
- 14. Revised Versions of this License.
-
- The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation. If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
- If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
- Later license versions may give you additional or different
-permissions. However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
- 15. Disclaimer of Warranty.
-
- THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. Limitation of Liability.
-
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
- 17. Interpretation of Sections 15 and 16.
-
- If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation, either version 3 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read

- This file describes how to build and install less using
-the "configure" script. This only works on Unix systems.
-To install on other systems, read the README file.
-
-
-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
- The file `configure.in' is used to create `configure' by a program
-called `autoconf'. You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. You can give `configure'
-initial values for variables by setting them in the environment. Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
- CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
- env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
- CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
- Use and save the results of the tests in FILE instead of
- `./config.cache'. Set FILE to `/dev/null' to disable caching, for
- debugging `configure'.
-
-`--help'
- Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made.
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--version'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that

+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some

+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

-
-* New command ESC-/ searches all files (on the command line)
- for a pattern.
-
-* New command ESC-n repeats previous search, spanning files.
-

-
-* Examining a file which was previously examined will return
- to the same position in the file.

-
-* New command "s" is equivalent to "-l".
-
-* The - command may be followed by "+X" to revert to the default
- for option X, or "-X" to get the opposite of the default.

+
+======================================================================
+
+
+ Major changes between "less" versions 291 and 321

+
+* A LESSOPEN preprocessor may now pipe the converted file data to less,
+ rather than writing it to a temporary file.
+
+* Search pattern highlighting has been fixed. It now highlights
+ reliably, even if a string is split across two screen lines,
+ contains TABs, etc.
+
+* The -F flag (which suppress search highlighting) has been changed
+ to -G. A new flag, -g, changes search highlighting to highlight

+
+* New flag -I acts like -i, but ignores case even if the search
+ pattern contains uppercase letters.
+

+
+* Ported to OS/2.
+
+======================================================================
+
+
+ Major changes between "less" versions 237 and 252

+
+
+======================================================================
+
+
+ Major changes between "less" versions 170 and 237
+
+* By popular demand, text which matches the current search pattern
+ is highlighted. New -F flag disables this feature.
+
+* Henry Spencer's regexp.c is now included, for systems which do not
+ have a regular expression library.
+ regexp.c is Copyright (c) 1986 by University of Toronto.
+
+* New line-editing keys, including command history (arrow keys) and
+ filename completion (TAB).
+
+* Input preprocessor allows modification of input files (e.g. uncompress)
+ via LESSOPEN/LESSCLOSE environment variables.
+
+* New -X flag disables sending termcap "ti" and "te" (initialize and
+ deinitialize) strings to the terminal.
+
+* Changing -i from within less now correctly affects a subsequent
+ repeated search.
+
+* Searching for underlined or overstruck text now works when the -u
+ flag is in effect, rather than the -i flag.
+
+* Use setlocale (LANG and LC_CTYPE environment variables) to determine
+ the character set if LESSCHARSET/LESSCHARDEF are not set.
+
+* The default format for displaying binary characters is now standout
+ (reverse video) rather than blinking. This can still be changed by
+ setting the LESSBINFMT environment variable.
+
+* Use autoconf installation technology.
+
+* Ported to MS-DOS.
+
+ ********************************
+ Things that may surprise you
+ ********************************
+
+* When you enter text at the bottom of the screen (search string,
+ filename, etc.), some keys act different than previously.
+ Specifically, \ (backslash), ESC, TAB, BACKTAB, and control-L
+ now have line editing functions.
+
+* Some previous unofficial versions of less were able to display
+ compressed files. The new LESSOPEN/LESSCLOSE feature now provides
+ this functionality in a different way.
+
+* Some previous unofficial versions of less provided a -Z flag to
+ set the number of lines of text to retain between full screen scrolls.
+ The -z-n flag (that is, -z with a negative number) provides this
+ functionality.
+
+
+======================================================================
+
+
+ Major changes between "less" versions 123 and 170
+
+* New option -j allows target lines to be positioned anywhere on screen.
+
+* New option -S truncates displayed line at the screen width,
+ rather than wrapping onto the next line.
+
+* New option -y limits amount of forward scroll.
+
+* New option -T specifies a "tags" file.
+
+* Non-printable, non-control characters are displayed in octal.
+ Such characters, as well as control characters, are displayed
+ in blinking mode.
+
+* New command -+ sets an option to its default.
+* New command -- sets an option to the opposite of its default.
+
+* Lesskey file may have a string appended to a key's action,
+ which acts as though typed in after the command.
+
+* New commands ESC-^F and ESC-^B match arbitrary types of brackets.
+
+* New command F monitors a growing file (like "tail -f").
+
+* New command | pipes a section of the input file into a shell command.
+
+* New command :x directly jumps to a file in the command line list.
+
+* Search commands have been enhanced and reorganized:
+ n Repeat search, same direction.
+ N Repeat search, opposite direction.
+ ESC-/ Search forward thru file boundaries
+ ESC-? Search backward thru file boundaries
+ ESC-n Repeat search thru file boundaries, same direction.
+ ESC-N Repeat search thru file boundaries, opposite direction.
+ Special character * causes search to search thru file boundaries.
+ Special character @ causes search to begin at start/end of file list.
+
+* Examining a new file adds it to the command line list.
+ A list of files, or an expression which matches more than one file,
+ may be examined; all of them are added to the command line list.
+
+* Environment variables LESSCHARSET and LESSCHARDEF can define
+ a non-ASCII character set.
+
+* Partial support for MSDOS, including options -R for repainting screen
+ on quit, -v/-V to select video mode, and -W to change window size.
+
+
+======================================================================
+
+
+ Major changes between "less" versions 97 and 123
+
+* New option (-N) causes line numbers to be displayed in the
+ text of the file (like vi "set nu").
+
+* New option (-?) prints help message immediately.
+
+* New option (-r) displays "raw" control characters, without
+ mapping them to ^X notation.
+
+* New option (-f) forces less to open non-regular files
+ (directories, etc).
+
+* New option (-k) can be used to specify lesskey files by name.
+
+* New option (-y) can be used to set a forward scroll limit
+ (like -h sets a backward scroll limit).
+
+* File marks (set by the m command) are now preserved when a new
+ file is edited. The ' command can thus be used to switch files.
+
+* New command ESC-/ searches all files (on the command line)
+ for a pattern.
+
+* New command ESC-n repeats previous search, spanning files.
+
+* The N command has been changed to repeat the previous search
+ in the reverse direction. The old N command is still available
+ via :n.
+
+* New command ESC-N repeats previous search in the reverse
+ direction and spanning files.
+
+* 8 bit characters are now supported. A new option (-g) can be
+ used to strip off the eighth bit (the previous behavior).
+
+* Options which take a following string (like -t) may now
+ optionally have a space between the option letter and the string.
+
+* Six new commands { } ( ) [ and ] can be used to match
+ brackets of specific types, similar to vi % command.
+
+* New commands z and w move forward/backward one window and
+ simultaneously set the window size.
+
+* Prompt string expansion now has %L for line number of the last
+ line in the file, and %E for the name of the editor.
+ Also, % escapes which refer to a line (b=bottom, t=top, etc.)
+ can use j for the jump target line.
+
+* New environment variable LESSEDIT can be used to tailor the
+ command string passed to the editor by the v command.
+
+* Examining a file which was previously examined will return
+ to the same position in the file.
+
+* A "%" is expanded to the current filename and a "#" to the
+ previous filename, in both shell commands and the E command.
+ (Previously % worked only in shell commands and # worked
+ only in the E command.)
+
+* New command ":ta" is equivalent to "-t".
+
+* New command "s" is equivalent to "-l".
+
+* The - command may be followed by "+X" to revert to the default
+ for option X, or "-X" to get the opposite of the default.
+
+* Lesskey files may now include characters after the action as
+ extra input to be parsed after the action; for example:
+ "toggle-option X" to toggle a specific option X.

- Less, version 436
-
- This is the distribution of less, version 436, released 07 Jul 2009.
- This program is part of the GNU project (http://www.gnu.org).
-
- This program is free software. You may redistribute it and/or

-
- Please report any problems to bug-less at gnu.org or markn at greenwoodsoftware.com.
- See http://www.greenwoodsoftware.com/less for the latest info.
-
-=========================================================================
-
-This is the distribution of "less", a paginator similar to "more" or "pg".
-
-The formatted manual page is in less.man.
-The manual page nroff source is in less.nro.
-Major changes made since the last posted version are in NEWS.
-
-=======================================================================
-INSTALLATION (Unix systems only):
-
-1. Move the distributed source to its own directory and unpack it,
- if you have not already done so.
-
-2. Type "sh configure".
- This will generate a Makefile and a defines.h.
- Warning: if you have a GNU sed, make sure it is version 2.05 or later.
-
- The file INSTALL describes the usage of the configure program in
- general. In addition, these options to configure are supported:
-
- --with-editor=program
- Specifies the default editor program used by the "v" command.
- The default is "vi".
-
- --with-regex=lib
- Specifies the regular expression library used by less for pattern
- matching. The default is "auto", which means the configure program
- finds a regular expression library automatically. Other values are:
- posix Use the POSIX-compatible regcomp.
- pcre Use the PCRE library.
- regcmp Use the regcmp library.
- re_comp Use the re_comp library.
- regcomp Use the V8-compatible regcomp.
- regcomp-local Use Henry Spencer's V8-compatible regcomp
- (source is supplied with less).
- --with-secure
- Builds a "secure" version of less, with some features disabled
- to prevent users from viewing other files, accessing shell
- commands, etc.
-
-
-3. It is a good idea to look over the generated Makefile and defines.h
- and make sure they look ok. If you know of any peculiarities of
- your system that configure might not have detected, you may fix the
- Makefile now. Take particular notice of the list of "terminal"
- libraries in the LIBS definition in the Makefile; these may need
- to be edited. The terminal libraries will be some subset of
- -lncurses -lcurses -ltermcap -ltermlib
-
- If you wish, you may edit defines.h to remove some optional features.
- If you choose not to include some features in your version, you may
- wish to edit the manual page "less.nro" and the help page "less.hlp"
- to remove the descriptions of the features which you are removing.
- If you edit less.hlp, you should run "make -f Makefile.aut help.c".
-
-4. Type "make" and watch the fun.
-
-5. If the make succeeds, it will generate the programs "less",
- "lesskey" and "lessecho" in your current directory. Test the
- generated programs.
-
-6. When satisfied that it works, if you wish to install it
- in a public place, type "make install".
-
- The default install destinations are:
- Executables (less, lesskey, lessecho) in /usr/local/bin
- Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
- If you want to install any of these files elsewhere, define
- bindir and/or mandir to the appropriate directories.
-
-If you have any problems building or running "less", suggestions,
-complaints, etc., you may mail to the author at markn at greenwoodsoftware.com.
-
-Note to hackers: comments noting possible improvements are enclosed
-in double curly brackets {{ like this }}.
-
-
-
-=======================================================================
-INSTALLATION (MS-DOS systems only,
- with Microsoft C, Borland C, or DJGPP)
-
-1. Move the distributed source to its own directory.
- Depending on your compiler, you may need to convert the source
- to have CR-LF rather than LF as line terminators.
-
-2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
- If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
- If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
-
-3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
- are correct. CC should be the name of your C compiler and
- LIBDIR should be the directory where the C libraries reside (for
- Microsoft C only). If these definitions need to be changed, you can
- either modify the definitions directly in MAKEFILE, or set your
- environment variables CC and/or LIBDIR to override the definitions
- in MAKEFILE.
-
-4. If you wish, you may edit DEFINES.DS to remove some optional features.
- If you choose not to include some features in your version, you may
- wish to edit the manual page LESS.MAN and the help page HELP.C
- to remove the descriptions of the features which you are removing.
-
-5. Run your "make" program and watch the fun.
- If your "make" requires a flag to import environment variables,
- you should use that flag.
- If your compiler runs out of memory, try running "make -n >cmds.bat"
- and then run cmds.bat.
-
-6. If the make succeeds, it will generate the programs "LESS.EXE" and
- "LESSKEY.EXE" in your current directory. Test the generated programs.
-
-7. When satisfied that it works, you may wish to install LESS.EXE and
- LESSKEY.EXE in a directory which is included in your PATH.
-
-
-
-=======================================================================
-INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only,
- with Borland C or Microsoft Visual C++)
-
-1. Move the distributed source to its own directory.
-
-2. If you are using Borland C, rename Makefile.wnb to Makefile.
- If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
-
-3. Check the Makefile to make sure the definitions look ok.
-
-4. If you wish, you may edit defines.wn to remove some optional features.
- If you choose not to include some features in your version, you may
- wish to edit the manual page less.man and the help page help.c
- to remove the descriptions of the features which you are removing.
-
-5. Type "make" and watch the fun.
-
-6. If the make succeeds, it will generate the programs "less.exe" and
- "lesskey.exe" in your current directory. Test the generated programs.
-
-7. When satisfied that it works, if you wish to install it
- in a public place, type "make install".
- See step 6 of the Unix installation instructions for details
- on how to change the default installation directories.
-
-
-
-=======================================================================
-INSTALLATION (OS/2 systems only,
- with EMX C)
-
-1. Move the distributed source to its own directory.
-
-2. Rename Makefile.o2e to Makefile.
-
-3. Check the Makefile to make sure the definitions look ok.
-
-4. If you wish, you may edit defines.o2 to remove some optional features.
- If you choose not to include some features in your version, you may
- wish to edit the manual page less.man and the help page help.c
- to remove the descriptions of the features which you are removing.
-
-5. Type "make" and watch the fun.
-
-6. If the make succeeds, it will generate the programs "less.exe" and
- "lesskey.exe" in your current directory. Test the generated programs.
-
-7. Make sure you have the emx runtime installed. You need the emx DLLs
- emx.dll and emxlibcs.dll and also the termcap database, termcap.dat.
- Make sure you have termcap.dat either in the default location or
- somewhere in a directory listed in the PATH or INIT environment
- variables.
-
-8. When satisfied that it works, you may wish to install less.exe,
- lesskey.exe and scrsize.exe in a directory which is included in
- your PATH. scrsize.exe is required only if you use a terminal
- emulator such as xterm or rxvt.
-
-
-
-=======================================================================
-INSTALLATION (OS-9 systems only,
- with Microware C or Ultra C)
-
-1. Move the distributed source to its own directory.
-
-2. If you are using Microware C, rename Makefile.o9c to Makefile.
- If you are using Ultra C, rename Makefile.o9u to Makefile.
-
-3. Check the Makefile to make sure the definitions look ok.
-
-4. If you wish, you may edit defines.o9 to remove some optional features.
- If you choose not to include some features in your version, you may
- wish to edit the manual page less.man and the help page help.c
- to remove the descriptions of the features which you are removing.
-
-5. Type "dmake" and watch the fun.
- The standard OS-9 "make" will probably not work. If you don't
- have dmake, you can get a copy from os9archive.rtsi.com.
-
-6. If the make succeeds, it will generate the programs "less" and
- "lesskey" in your current directory. Test the generated programs.
-
-7. When satisfied that it works, if you wish to install it
- in a public place, type "dmake install".
- See step 6 of the Unix installation instructions for details
- on how to change the default installation directories.

+
+=========================================================================
+
+This is the distribution of "less", a paginator similar to "more" or "pg".
+
+The formatted manual page is in less.man.
+The manual page nroff source is in less.nro.
+Major changes made since the last posted version are in NEWS.
+
+=======================================================================
+INSTALLATION (Unix systems only):
+
+1. Move the distributed source to its own directory and unpack it,
+ if you have not already done so.
+
+2. Type "sh configure".
+ This will generate a Makefile and a defines.h.
+ Warning: if you have a GNU sed, make sure it is version 2.05 or later.
+
+ The file INSTALL describes the usage of the configure program in
+ general. In addition, these options to configure are supported:
+
+ --with-editor=program
+ Specifies the default editor program used by the "v" command.
+ The default is "vi".
+
+ --with-regex=lib
+ Specifies the regular expression library used by less for pattern
+ matching. The default is "auto", which means the configure program
+ finds a regular expression library automatically. Other values are:
+ posix Use the POSIX-compatible regcomp.
+ pcre Use the PCRE library.
+ regcmp Use the regcmp library.
+ re_comp Use the re_comp library.
+ regcomp Use the V8-compatible regcomp.
+ regcomp-local Use Henry Spencer's V8-compatible regcomp
+ (source is supplied with less).
+ none No regular expressions, only simple string matching.
+ --with-secure
+ Builds a "secure" version of less, with some features disabled
+ to prevent users from viewing other files, accessing shell
+ commands, etc.
+
+
+3. It is a good idea to look over the generated Makefile and defines.h
+ and make sure they look ok. If you know of any peculiarities of
+ your system that configure might not have detected, you may fix the
+ Makefile now. Take particular notice of the list of "terminal"
+ libraries in the LIBS definition in the Makefile; these may need
+ to be edited. The terminal libraries will be some subset of
+ -lncurses -lcurses -ltermcap -ltermlib
+
+ If you wish, you may edit defines.h to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page "less.nro" and the help page "less.hlp"
+ to remove the descriptions of the features which you are removing.
+ If you edit less.hlp, you should run "make -f Makefile.aut help.c".
+
+4. Type "make" and watch the fun.
+
+5. If the make succeeds, it will generate the programs "less",
+ "lesskey" and "lessecho" in your current directory. Test the
+ generated programs.
+
+6. When satisfied that it works, if you wish to install it
+ in a public place, type "make install".
+
+ The default install destinations are:
+ Executables (less, lesskey, lessecho) in /usr/local/bin
+ Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
+ If you want to install any of these files elsewhere, define
+ bindir and/or mandir to the appropriate directories.
+
+If you have any problems building or running "less", suggestions,
+complaints, etc., you may mail to bug-less at gnu.org.
+
+Note to hackers: comments noting possible improvements are enclosed
+in double curly brackets {{ like this }}.
+
+(Note that the above note was originally written at a time when
+"hackers" most commonly meant "enthusiastic and dedicated computer
+programmers", not "persons who attempt to circumvent computer security".)
+
+
+
+=======================================================================
+INSTALLATION (MS-DOS systems only,
+ with Microsoft C, Borland C, or DJGPP)
+
+1. Move the distributed source to its own directory.
+ Depending on your compiler, you may need to convert the source
+ to have CR-LF rather than LF as line terminators.
+
+2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
+ If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
+ If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
+
+3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
+ are correct. CC should be the name of your C compiler and
+ LIBDIR should be the directory where the C libraries reside (for
+ Microsoft C only). If these definitions need to be changed, you can
+ either modify the definitions directly in MAKEFILE, or set your
+ environment variables CC and/or LIBDIR to override the definitions
+ in MAKEFILE.
+
+4. If you wish, you may edit DEFINES.DS to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page LESS.MAN and the help page HELP.C
+ to remove the descriptions of the features which you are removing.
+
+5. Run your "make" program and watch the fun.
+ If your "make" requires a flag to import environment variables,
+ you should use that flag.
+ If your compiler runs out of memory, try running "make -n >cmds.bat"
+ and then run cmds.bat.
+
+6. If the make succeeds, it will generate the programs "LESS.EXE" and
+ "LESSKEY.EXE" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, you may wish to install LESS.EXE and
+ LESSKEY.EXE in a directory which is included in your PATH.
+
+
+
+=======================================================================
+INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only,
+ with Borland C or Microsoft Visual C++)
+
+1. Move the distributed source to its own directory.
+
+2. If you are using Borland C, rename Makefile.wnb to Makefile.
+ If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.wn to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+ "lesskey.exe" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, if you wish to install it
+ in a public place, type "make install".
+ See step 6 of the Unix installation instructions for details
+ on how to change the default installation directories.
+
+
+
+=======================================================================
+INSTALLATION (OS/2 systems only,
+ with EMX C)
+
+1. Move the distributed source to its own directory.
+
+2. Rename Makefile.o2e to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.o2 to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+ "lesskey.exe" in your current directory. Test the generated programs.
+
+7. Make sure you have the emx runtime installed. You need the emx DLLs
+ emx.dll and emxlibcs.dll and also the termcap database, termcap.dat.
+ Make sure you have termcap.dat either in the default location or
+ somewhere in a directory listed in the PATH or INIT environment
+ variables.
+
+8. When satisfied that it works, you may wish to install less.exe,
+ lesskey.exe and scrsize.exe in a directory which is included in
+ your PATH. scrsize.exe is required only if you use a terminal
+ emulator such as xterm or rxvt.
+
+
+
+=======================================================================
+INSTALLATION (OS-9 systems only,
+ with Microware C or Ultra C)
+
+1. Move the distributed source to its own directory.
+
+2. If you are using Microware C, rename Makefile.o9c to Makefile.
+ If you are using Ultra C, rename Makefile.o9u to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.o9 to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "dmake" and watch the fun.
+ The standard OS-9 "make" will probably not work. If you don't
+ have dmake, you can get a copy from os9archive.rtsi.com.
+
+6. If the make succeeds, it will generate the programs "less" and
+ "lesskey" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, if you wish to install it
+ in a public place, type "dmake install".
+ See step 6 of the Unix installation instructions for details
+ on how to change the default installation directories.

-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

- --with-secure Compile in secure mode
- --with-regex={auto,pcre,posix,regcmp,re_comp,regcomp,regcomp-local} Select a regular expression library auto
- --with-editor=PROGRAM use PROGRAM as the default editor vi
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if

+\`configure' configures less 1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
+ --mandir=DIR man documentation [DATAROOTDIR/man]

+ --disable-largefile omit support for large files
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]

+ --with-secure Compile in secure mode
+ --with-no-float Do not use floating point
+ --with-regex={auto,gnu,pcre,posix,regcmp,re_comp,regcomp,regcomp-local,none} Select a regular expression library auto
+ --with-editor=PROGRAM use PROGRAM as the default editor vi
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

- * Routines to decode user commands.
- *
- * This is all table driven.
- * A command table is a sequence of command descriptors.
- * Each command descriptor is a sequence of bytes with the following format:
- * <c1><c2>...<cN><0><action>
- * The characters c1,c2,...,cN are the command string; that is,
- * the characters which the user must type.
- * It is terminated by a null <0> byte.
- * The byte after the null byte is the action code associated
- * with the command string.
- * If an action byte is OR-ed with A_EXTRA, this indicates
- * that the option byte is followed by an extra string.
- *
- * There may be many command tables.
- * The first (default) table is built-in.
- * Other tables are read in from "lesskey" files.
- * All the tables are linked together and are searched in order.

+ * This is all table driven.
+ * A command table is a sequence of command descriptors.
+ * Each command descriptor is a sequence of bytes with the following format:
+ * <c1><c2>...<cN><0><action>
+ * The characters c1,c2,...,cN are the command string; that is,
+ * the characters which the user must type.
+ * It is terminated by a null <0> byte.
+ * The byte after the null byte is the action code associated
+ * with the command string.
+ * If an action byte is OR-ed with A_EXTRA, this indicates
+ * that the option byte is followed by an extra string.
+ *
+ * There may be many command tables.
+ * The first (default) table is built-in.
+ * Other tables are read in from "lesskey" files.
+ * All the tables are linked together and are searched in order.

-[1mDESCRIPTION[0m
- [4mLess[24m is a program similar to [4mmore[24m (1), but which allows backward move-
- ment in the file as well as forward movement. Also, [4mless[24m does not have
- to read the entire input file before starting, so with large input
- files it starts up faster than text editors like [4mvi[24m (1). [4mLess[24m uses
- termcap (or terminfo on some systems), so it can run on a variety of
- terminals. There is even limited support for hardcopy terminals. (On
- a hardcopy terminal, lines which should be printed at the top of the
- screen are prefixed with a caret.)
-
- Commands are based on both [4mmore[24m and [4mvi.[24m Commands may be preceded by a
- decimal number, called N in the descriptions below. The number is used
- by some commands, as indicated.
-
-
-[1mCOMMANDS[0m
- In the following descriptions, ^X means control-X. ESC stands for the
- ESCAPE key; for example ESC-v means the two character sequence
- "ESCAPE", then "v".
-
- h or H Help: display a summary of these commands. If you forget all
- the other commands, remember this one.
-
- SPACE or ^V or f or ^F
- Scroll forward N lines, default one window (see option -z
- below). If N is more than the screen size, only the final
- screenful is displayed. Warning: some systems use ^V as a spe-
- cial literalization character.
-
- z Like SPACE, but if N is specified, it becomes the new window
- size.
-
- ESC-SPACE
- Like SPACE, but scrolls a full screenful, even if it reaches
- end-of-file in the process.
-
- RETURN or ^N or e or ^E or j or ^J
- Scroll forward N lines, default 1. The entire N lines are dis-
- played, even if N is more than the screen size.
-
- d or ^D
- Scroll forward N lines, default one half of the screen size. If
- N is specified, it becomes the new default for subsequent d and
- u commands.
-
- b or ^B or ESC-v
- Scroll backward N lines, default one window (see option -z
- below). If N is more than the screen size, only the final
- screenful is displayed.
-
- w Like ESC-v, but if N is specified, it becomes the new window
- size.
-
- y or ^Y or ^P or k or ^K
- Scroll backward N lines, default 1. The entire N lines are dis-
- played, even if N is more than the screen size. Warning: some
- systems use ^Y as a special job control character.
-
- u or ^U
- Scroll backward N lines, default one half of the screen size.
- If N is specified, it becomes the new default for subsequent d
- and u commands.
-
- ESC-) or RIGHTARROW
- Scroll horizontally right N characters, default half the screen
- width (see the -# option). If a number N is specified, it
- becomes the default for future RIGHTARROW and LEFTARROW com-
- mands. While the text is scrolled, it acts as though the -S
- option (chop lines) were in effect.
-
- ESC-( or LEFTARROW
- Scroll horizontally left N characters, default half the screen
- width (see the -# option). If a number N is specified, it
- becomes the default for future RIGHTARROW and LEFTARROW com-
- mands.
-
- r or ^R or ^L
- Repaint the screen.
-
- R Repaint the screen, discarding any buffered input. Useful if
- the file is changing while it is being viewed.
-
- F Scroll forward, and keep trying to read when the end of file is
- reached. Normally this command would be used when already at
- the end of the file. It is a way to monitor the tail of a file
- which is growing while it is being viewed. (The behavior is
- similar to the "tail -f" command.)
-
- g or < or ESC-<
- Go to line N in the file, default 1 (beginning of file). (Warn-
- ing: this may be slow if N is large.)
-
- G or > or ESC->
- Go to line N in the file, default the end of the file. (Warn-
- ing: this may be slow if N is large, or if N is not specified
- and standard input, rather than a file, is being read.)
-
- p or % Go to a position N percent into the file. N should be between 0
- and 100, and may contain a decimal point.
-
- P Go to the line containing byte offset N in the file.
-
- { If a left curly bracket appears in the top line displayed on the
- screen, the { command will go to the matching right curly
- bracket. The matching right curly bracket is positioned on the
- bottom line of the screen. If there is more than one left curly
- bracket on the top line, a number N may be used to specify the
- N-th bracket on the line.
-
- } If a right curly bracket appears in the bottom line displayed on
- the screen, the } command will go to the matching left curly
- bracket. The matching left curly bracket is positioned on the
- top line of the screen. If there is more than one right curly
- bracket on the top line, a number N may be used to specify the
- N-th bracket on the line.
-
- ( Like {, but applies to parentheses rather than curly brackets.
-
- ) Like }, but applies to parentheses rather than curly brackets.
-
- [ Like {, but applies to square brackets rather than curly brack-
- ets.
-
- ] Like }, but applies to square brackets rather than curly brack-
- ets.
-
- ESC-^F Followed by two characters, acts like {, but uses the two char-
- acters as open and close brackets, respectively. For example,
- "ESC ^F < >" could be used to go forward to the > which matches
- the < in the top displayed line.
-
- ESC-^B Followed by two characters, acts like }, but uses the two char-
- acters as open and close brackets, respectively. For example,
- "ESC ^B < >" could be used to go backward to the < which matches
- the > in the bottom displayed line.
-
- m Followed by any lowercase letter, marks the current position
- with that letter.
-
- ' (Single quote.) Followed by any lowercase letter, returns to
- the position which was previously marked with that letter. Fol-
- lowed by another single quote, returns to the position at which
- the last "large" movement command was executed. Followed by a ^
- or $, jumps to the beginning or end of the file respectively.
- Marks are preserved when a new file is examined, so the ' com-
- mand can be used to switch between input files.
-
- ^X^X Same as single quote.
-
- /pattern
- Search forward in the file for the N-th line containing the pat-
- tern. N defaults to 1. The pattern is a regular expression, as
- recognized by the regular expression library supplied by your
- system. The search starts at the second line displayed (but see
- the -a and -j options, which change this).
-
- Certain characters are special if entered at the beginning of
- the pattern; they modify the type of search rather than become
- part of the pattern:
-
- ^N or !
- Search for lines which do NOT match the pattern.
-
- ^E or *
- Search multiple files. That is, if the search reaches
- the END of the current file without finding a match, the
- search continues in the next file in the command line
- list.
-
- ^F or @
- Begin the search at the first line of the FIRST file in
- the command line list, regardless of what is currently
- displayed on the screen or the settings of the -a or -j
- options.
-
- ^K Highlight any text which matches the pattern on the cur-
- rent screen, but don't move to the first match (KEEP cur-
- rent position).
-
- ^R Don't interpret regular expression metacharacters; that
- is, do a simple textual comparison.
-
- ?pattern
- Search backward in the file for the N-th line containing the
- pattern. The search starts at the line immediately before the
- top line displayed.
-
- Certain characters are special as in the / command:
-
- ^N or !
- Search for lines which do NOT match the pattern.
-
- ^E or *
- Search multiple files. That is, if the search reaches
- the beginning of the current file without finding a
- match, the search continues in the previous file in the
- command line list.
-
- ^F or @
- Begin the search at the last line of the last file in the
- command line list, regardless of what is currently dis-
- played on the screen or the settings of the -a or -j
- options.
-
- ^K As in forward searches.
-
- ^R As in forward searches.

- ESC-/pattern
- Same as "/*".
-
- ESC-?pattern
- Same as "?*".
-
- n Repeat previous search, for N-th line containing the last pat-
- tern. If the previous search was modified by ^N, the search is
- made for the N-th line NOT containing the pattern. If the pre-
- vious search was modified by ^E, the search continues in the
- next (or previous) file if not satisfied in the current file.
- If the previous search was modified by ^R, the search is done
- without using regular expressions. There is no effect if the
- previous search was modified by ^F or ^K.
-
- N Repeat previous search, but in the reverse direction.
-
- ESC-n Repeat previous search, but crossing file boundaries. The
- effect is as if the previous search were modified by *.
-
- ESC-N Repeat previous search, but in the reverse direction and cross-
- ing file boundaries.
-
- ESC-u Undo search highlighting. Turn off highlighting of strings
- matching the current search pattern. If highlighting is already
- off because of a previous ESC-u command, turn highlighting back
- on. Any search command will also turn highlighting back on.
- (Highlighting can also be disabled by toggling the -G option; in
- that case search commands do not turn highlighting back on.)
-
- &pattern
- Display only lines which match the pattern; lines which do not
- match the pattern are not displayed. If pattern is empty (if
- you type & immediately followed by ENTER), any filtering is
- turned off, and all lines are displayed. While filtering is in
- effect, an ampersand is displayed at the beginning of the
- prompt, as a reminder that some lines in the file may be hidden.
-
- Certain characters are special as in the / command:
-
- ^N or !
- Display only lines which do NOT match the pattern.
-
- ^R Don't interpret regular expression metacharacters; that
- is, do a simple textual comparison.
-
- :e [filename]
- Examine a new file. If the filename is missing, the "current"
- file (see the :n and :p commands below) from the list of files
- in the command line is re-examined. A percent sign (%) in the
- filename is replaced by the name of the current file. A pound
- sign (#) is replaced by the name of the previously examined
- file. However, two consecutive percent signs are simply
- replaced with a single percent sign. This allows you to enter a
- filename that contains a percent sign in the name. Similarly,
- two consecutive pound signs are replaced with a single pound
- sign. The filename is inserted into the command line list of
- files so that it can be seen by subsequent :n and :p commands.
- If the filename consists of several files, they are all inserted
- into the list of files and the first one is examined. If the
- filename contains one or more spaces, the entire filename should
- be enclosed in double quotes (also see the -" option).
-
- ^X^V or E
- Same as :e. Warning: some systems use ^V as a special literal-
- ization character. On such systems, you may not be able to use
- ^V.
-
- :n Examine the next file (from the list of files given in the com-
- mand line). If a number N is specified, the N-th next file is
- examined.
-
- :p Examine the previous file in the command line list. If a number
- N is specified, the N-th previous file is examined.
-
- :x Examine the first file in the command line list. If a number N
- is specified, the N-th file in the list is examined.
-
- :d Remove the current file from the list of files.
-
- t Go to the next tag, if there were more than one matches for the
- current tag. See the -t option for more details about tags.
-
- T Go to the previous tag, if there were more than one matches for
- the current tag.
-
- = or ^G or :f
- Prints some information about the file being viewed, including
- its name and the line number and byte offset of the bottom line
- being displayed. If possible, it also prints the length of the
- file, the number of lines in the file and the percent of the
- file above the last displayed line.
-
- - Followed by one of the command line option letters (see OPTIONS
- below), this will change the setting of that option and print a
- message describing the new setting. If a ^P (CONTROL-P) is
- entered immediately after the dash, the setting of the option is
- changed but no message is printed. If the option letter has a
- numeric value (such as -b or -h), or a string value (such as -P
- or -t), a new value may be entered after the option letter. If
- no new value is entered, a message describing the current set-
- ting is printed and nothing is changed.
-
- -- Like the - command, but takes a long option name (see OPTIONS
- below) rather than a single option letter. You must press
- RETURN after typing the option name. A ^P immediately after the
- second dash suppresses printing of a message describing the new
- setting, as in the - command.
-
- -+ Followed by one of the command line option letters this will
- reset the option to its default setting and print a message
- describing the new setting. (The "-+[4mX[24m" command does the same
- thing as "-+[4mX[24m" on the command line.) This does not work for
- string-valued options.
-
- --+ Like the -+ command, but takes a long option name rather than a
- single option letter.
-
- -! Followed by one of the command line option letters, this will
- reset the option to the "opposite" of its default setting and
- print a message describing the new setting. This does not work
- for numeric or string-valued options.
-
- --! Like the -! command, but takes a long option name rather than a
- single option letter.
-
- _ (Underscore.) Followed by one of the command line option let-
- ters, this will print a message describing the current setting
- of that option. The setting of the option is not changed.
-
- __ (Double underscore.) Like the _ (underscore) command, but takes
- a long option name rather than a single option letter. You must
- press RETURN after typing the option name.
-
- +cmd Causes the specified cmd to be executed each time a new file is
- examined. For example, +G causes [4mless[24m to initially display each
- file starting at the end rather than the beginning.
-
- V Prints the version number of [4mless[24m being run.
-
- q or Q or :q or :Q or ZZ
- Exits [4mless.[0m
-
- The following four commands may or may not be valid, depending on your
- particular installation.
-
-
- v Invokes an editor to edit the current file being viewed. The
- editor is taken from the environment variable VISUAL if defined,
- or EDITOR if VISUAL is not defined, or defaults to "vi" if nei-
- ther VISUAL nor EDITOR is defined. See also the discussion of
- LESSEDIT under the section on PROMPTS below.
-
- ! shell-command
- Invokes a shell to run the shell-command given. A percent sign
- (%) in the command is replaced by the name of the current file.
- A pound sign (#) is replaced by the name of the previously exam-
- ined file. "!!" repeats the last shell command. "!" with no
- shell command simply invokes a shell. On Unix systems, the
- shell is taken from the environment variable SHELL, or defaults
- to "sh". On MS-DOS and OS/2 systems, the shell is the normal
- command processor.
-
- | <m> shell-command
- <m> represents any mark letter. Pipes a section of the input
- file to the given shell command. The section of the file to be
- piped is between the first line on the current screen and the
- position marked by the letter. <m> may also be ^ or $ to indi-
- cate beginning or end of file respectively. If <m> is . or new-
- line, the current screen is piped.
-
- s filename
- Save the input to a file. This only works if the input is a
- pipe, not an ordinary file.
-
-
-[1mOPTIONS[0m
- Command line options are described below. Most options may be changed
- while [4mless[24m is running, via the "-" command.
-
- Most options may be given in one of two forms: either a dash followed
- by a single letter, or two dashes followed by a long option name. A
- long option name may be abbreviated as long as the abbreviation is
- unambiguous. For example, --quit-at-eof may be abbreviated --quit, but
- not --qui, since both --quit-at-eof and --quiet begin with --qui. Some
- long option names are in uppercase, such as --QUIT-AT-EOF, as distinct
- from --quit-at-eof. Such option names need only have their first let-
- ter capitalized; the remainder of the name may be in either case. For
- example, --Quit-at-eof is equivalent to --QUIT-AT-EOF.
-
- Options are also taken from the environment variable "LESS". For exam-
- ple, to avoid typing "less -options ..." each time [4mless[24m is invoked, you
- might tell [4mcsh:[0m
-
- setenv LESS "-options"
-
- or if you use [4msh:[0m
-
- LESS="-options"; export LESS
-
- On MS-DOS, you don't need the quotes, but you should replace any per-
- cent signs in the options string by double percent signs.
-
- The environment variable is parsed before the command line, so command
- line options override the LESS environment variable. If an option
- appears in the LESS variable, it can be reset to its default value on
- the command line by beginning the command line option with "-+".
-
- For options like -P or -D which take a following string, a dollar sign
- ($) must be used to signal the end of the string. For example, to set
- two -D options on MS-DOS, you must have a dollar sign between them,
- like this:
-
- LESS="-Dn9.1$-Ds4.1"
-
-
- -? or --help
- This option displays a summary of the commands accepted by [4mless[0m
- (the same as the h command). (Depending on how your shell
- interprets the question mark, it may be necessary to quote the
- question mark, thus: "-\?".)
-
- -a or --search-skip-screen
- Causes searches to start after the last line displayed on the
- screen, thus skipping all lines displayed on the screen. By
- default, searches start at the second line on the screen (or
- after the last found line; see the -j option).
-
- -b[4mn[24m or --buffers=[4mn[0m
- Specifies the amount of buffer space [4mless[24m will use for each
- file, in units of kilobytes (1024 bytes). By default 64K of
- buffer space is used for each file (unless the file is a pipe;
- see the -B option). The -b option specifies instead that [4mn[0m
- kilobytes of buffer space should be used for each file. If [4mn[24m is
- -1, buffer space is unlimited; that is, the entire file can be
- read into memory.
-
- -B or --auto-buffers
- By default, when data is read from a pipe, buffers are allocated
- automatically as needed. If a large amount of data is read from
- the pipe, this can cause a large amount of memory to be allo-
- cated. The -B option disables this automatic allocation of
- buffers for pipes, so that only 64K (or the amount of space
- specified by the -b option) is used for the pipe. Warning: use
- of -B can result in erroneous display, since only the most
- recently viewed part of the piped data is kept in memory; any
- earlier data is lost.
-
- -c or --clear-screen
- Causes full screen repaints to be painted from the top line
- down. By default, full screen repaints are done by scrolling
- from the bottom of the screen.
-
- -C or --CLEAR-SCREEN
- Same as -c, for compatibility with older versions of [4mless.[0m
-
- -d or --dumb
- The -d option suppresses the error message normally displayed if
- the terminal is dumb; that is, lacks some important capability,
- such as the ability to clear the screen or scroll backward. The
- -d option does not otherwise change the behavior of [4mless[24m on a
- dumb terminal.
-
- -D[1mx[4m[22mcolor[24m or --color=[1mx[4m[22mcolor[0m
- [MS-DOS only] Sets the color of the text displayed. [1mx [22mis a sin-
- gle character which selects the type of text whose color is
- being set: n=normal, s=standout, d=bold, u=underlined, k=blink.
- [4mcolor[24m is a pair of numbers separated by a period. The first
- number selects the foreground color and the second selects the
- background color of the text. A single number [4mN[24m is the same as
- [4mN.M[24m, where [4mM[24m is the normal background color.
-
-
- -e or --quit-at-eof
- Causes [4mless[24m to automatically exit the second time it reaches
- end-of-file. By default, the only way to exit [4mless[24m is via the
- "q" command.
-
- -E or --QUIT-AT-EOF
- Causes [4mless[24m to automatically exit the first time it reaches end-
- of-file.
-
- -f or --force
- Forces non-regular files to be opened. (A non-regular file is a
- directory or a device special file.) Also suppresses the warn-
- ing message when a binary file is opened. By default, [4mless[24m will
- refuse to open non-regular files. Note that some operating sys-
- tems will not allow directories to be read, even if -f is set.
-
- -F or --quit-if-one-screen
- Causes [4mless[24m to automatically exit if the entire file can be dis-
- played on the first screen.
-
- -g or --hilite-search
- Normally, [4mless[24m will highlight ALL strings which match the last
- search command. The -g option changes this behavior to high-
- light only the particular string which was found by the last
- search command. This can cause [4mless[24m to run somewhat faster than
- the default.
-
- -G or --HILITE-SEARCH
- The -G option suppresses all highlighting of strings found by
- search commands.
-
- -h[4mn[24m or --max-back-scroll=[4mn[0m
- Specifies a maximum number of lines to scroll backward. If it
- is necessary to scroll backward more than [4mn[24m lines, the screen is
- repainted in a forward direction instead. (If the terminal does
- not have the ability to scroll backward, -h0 is implied.)
-
- -i or --ignore-case
- Causes searches to ignore case; that is, uppercase and lowercase
- are considered identical. This option is ignored if any upper-
- case letters appear in the search pattern; in other words, if a
- pattern contains uppercase letters, then that search does not
- ignore case.
-
- -I or --IGNORE-CASE
- Like -i, but searches ignore case even if the pattern contains
- uppercase letters.
-
- -j[4mn[24m or --jump-target=[4mn[0m
- Specifies a line on the screen where the "target" line is to be
- positioned. The target line is the line specified by any com-
- mand to search for a pattern, jump to a line number, jump to a
- file percentage or jump to a tag. The screen line may be speci-
- fied by a number: the top line on the screen is 1, the next is
- 2, and so on. The number may be negative to specify a line rel-
- ative to the bottom of the screen: the bottom line on the screen
- is -1, the second to the bottom is -2, and so on. Alternately,
- the screen line may be specified as a fraction of the height of
- the screen, starting with a decimal point: .5 is in the middle
- of the screen, .3 is three tenths down from the first line, and
- so on. If the line is specified as a fraction, the actual line
- number is recalculated if the terminal window is resized, so
- that the target line remains at the specified fraction of the
- screen height. If any form of the -j option is used, forward
- searches begin at the line immediately after the target line,
- and backward searches begin at the target line. For example, if
- "-j4" is used, the target line is the fourth line on the screen,
- so forward searches begin at the fifth line on the screen.
-
- -J or --status-column
- Displays a status column at the left edge of the screen. The
- status column shows the lines that matched the current search.
- The status column is also used if the -w or -W option is in
- effect.
-
- -k[4mfilename[24m or --lesskey-file=[4mfilename[0m
- Causes [4mless[24m to open and interpret the named file as a [4mlesskey[0m
- (1) file. Multiple -k options may be specified. If the LESSKEY
- or LESSKEY_SYSTEM environment variable is set, or if a lesskey
- file is found in a standard place (see KEY BINDINGS), it is also
- used as a [4mlesskey[24m file.
-
- -K or --quit-on-intr
- Causes [4mless[24m to exit immediately when an interrupt character
- (usually ^C) is typed. Normally, an interrupt character causes
- [4mless[24m to stop whatever it is doing and return to its command
- prompt. Note that use of this option makes it impossible to
- return to the command prompt from the "F" command.
-
- -L or --no-lessopen
- Ignore the LESSOPEN environment variable (see the INPUT PRE-
- PROCESSOR section below). This option can be set from within
- [4mless[24m, but it will apply only to files opened subsequently, not
- to the file which is currently open.
-
- -m or --long-prompt
- Causes [4mless[24m to prompt verbosely (like [4mmore[24m), with the percent
- into the file. By default, [4mless[24m prompts with a colon.
-
- -M or --LONG-PROMPT
- Causes [4mless[24m to prompt even more verbosely than [4mmore.[0m
-
- -n or --line-numbers
- Suppresses line numbers. The default (to use line numbers) may
- cause [4mless[24m to run more slowly in some cases, especially with a
- very large input file. Suppressing line numbers with the -n
- option will avoid this problem. Using line numbers means: the
- line number will be displayed in the verbose prompt and in the =
- command, and the v command will pass the current line number to
- the editor (see also the discussion of LESSEDIT in PROMPTS
- below).
-
- -N or --LINE-NUMBERS
- Causes a line number to be displayed at the beginning of each
- line in the display.
-
- -o[4mfilename[24m or --log-file=[4mfilename[0m
- Causes [4mless[24m to copy its input to the named file as it is being
- viewed. This applies only when the input file is a pipe, not an
- ordinary file. If the file already exists, [4mless[24m will ask for
- confirmation before overwriting it.
-
- -O[4mfilename[24m or --LOG-FILE=[4mfilename[0m
- The -O option is like -o, but it will overwrite an existing file
- without asking for confirmation.
-
- If no log file has been specified, the -o and -O options can be
- used from within [4mless[24m to specify a log file. Without a file
- name, they will simply report the name of the log file. The "s"
- command is equivalent to specifying -o from within [4mless.[0m
-
- -p[4mpattern[24m or --pattern=[4mpattern[0m
- The -p option on the command line is equivalent to specifying
- +/[4mpattern[24m; that is, it tells [4mless[24m to start at the first occur-
- rence of [4mpattern[24m in the file.
-
- -P[4mprompt[24m or --prompt=[4mprompt[0m
- Provides a way to tailor the three prompt styles to your own
- preference. This option would normally be put in the LESS envi-
- ronment variable, rather than being typed in with each [4mless[24m com-
- mand. Such an option must either be the last option in the LESS
- variable, or be terminated by a dollar sign. -Ps followed by a
- string changes the default (short) prompt to that string. -Pm
- changes the medium (-m) prompt. -PM changes the long (-M)
- prompt. -Ph changes the prompt for the help screen. -P=
- changes the message printed by the = command. -Pw changes the
- message printed while waiting for data (in the F command). All
- prompt strings consist of a sequence of letters and special
- escape sequences. See the section on PROMPTS for more details.
-
- -q or --quiet or --silent
- Causes moderately "quiet" operation: the terminal bell is not
- rung if an attempt is made to scroll past the end of the file or
- before the beginning of the file. If the terminal has a "visual
- bell", it is used instead. The bell will be rung on certain
- other errors, such as typing an invalid character. The default
- is to ring the terminal bell in all such cases.
-
- -Q or --QUIET or --SILENT
- Causes totally "quiet" operation: the terminal bell is never
- rung.
-
- -r or --raw-control-chars
- Causes "raw" control characters to be displayed. The default is
- to display control characters using the caret notation; for
- example, a control-A (octal 001) is displayed as "^A". Warning:
- when the -r option is used, [4mless[24m cannot keep track of the actual
- appearance of the screen (since this depends on how the screen
- responds to each type of control character). Thus, various dis-
- play problems may result, such as long lines being split in the
- wrong place.
-
- -R or --RAW-CONTROL-CHARS
- Like -r, but only ANSI "color" escape sequences are output in
- "raw" form. Unlike -r, the screen appearance is maintained cor-
- rectly in most cases. ANSI "color" escape sequences are
- sequences of the form:
-
- ESC [ ... m
-
- where the "..." is zero or more color specification characters
- For the purpose of keeping track of screen appearance, ANSI
- color escape sequences are assumed to not move the cursor. You
- can make [4mless[24m think that characters other than "m" can end ANSI
- color escape sequences by setting the environment variable
- LESSANSIENDCHARS to the list of characters which can end a color
- escape sequence. And you can make [4mless[24m think that characters
- other than the standard ones may appear between the ESC and the
- m by setting the environment variable LESSANSIMIDCHARS to the
- list of characters which can appear.
-
- -s or --squeeze-blank-lines
- Causes consecutive blank lines to be squeezed into a single
- blank line. This is useful when viewing [4mnroff[24m output.
-
- -S or --chop-long-lines
- Causes lines longer than the screen width to be chopped rather
- than folded. That is, the portion of a long line that does not
- fit in the screen width is not shown. The default is to fold
- long lines; that is, display the remainder on the next line.
-
- -t[4mtag[24m or --tag=[4mtag[0m
- The -t option, followed immediately by a TAG, will edit the file
- containing that tag. For this to work, tag information must be
- available; for example, there may be a file in the current
- directory called "tags", which was previously built by [4mctags[24m (1)
- or an equivalent command. If the environment variable LESSGLOB-
- ALTAGS is set, it is taken to be the name of a command compati-
- ble with [4mglobal[24m (1), and that command is executed to find the
- tag. (See http://www.gnu.org/software/global/global.html). The
- -t option may also be specified from within [4mless[24m (using the -
- command) as a way of examining a new file. The command ":t" is
- equivalent to specifying -t from within [4mless.[0m
-
- -T[4mtagsfile[24m or --tag-file=[4mtagsfile[0m
- Specifies a tags file to be used instead of "tags".
-
- -u or --underline-special
- Causes backspaces and carriage returns to be treated as print-
- able characters; that is, they are sent to the terminal when
- they appear in the input.
-
- -U or --UNDERLINE-SPECIAL
- Causes backspaces, tabs and carriage returns to be treated as
- control characters; that is, they are handled as specified by
- the -r option.
-
- By default, if neither -u nor -U is given, backspaces which
- appear adjacent to an underscore character are treated spe-
- cially: the underlined text is displayed using the terminal's
- hardware underlining capability. Also, backspaces which appear
- between two identical characters are treated specially: the
- overstruck text is printed using the terminal's hardware bold-
- face capability. Other backspaces are deleted, along with the
- preceding character. Carriage returns immediately followed by a
- newline are deleted. other carriage returns are handled as
- specified by the -r option. Text which is overstruck or under-
- lined can be searched for if neither -u nor -U is in effect.
-
- -V or --version
- Displays the version number of [4mless.[0m
-
- -w or --hilite-unread
- Temporarily highlights the first "new" line after a forward
- movement of a full page. The first "new" line is the line imme-
- diately following the line previously at the bottom of the
- screen. Also highlights the target line after a g or p command.
- The highlight is removed at the next command which causes move-
- ment. The entire line is highlighted, unless the -J option is
- in effect, in which case only the status column is highlighted.
-
- -W or --HILITE-UNREAD
- Like -w, but temporarily highlights the first new line after any
- forward movement command larger than one line.
-
- -x[4mn[24m,... or --tabs=[4mn[24m,...
- Sets tab stops. If only one [4mn[24m is specified, tab stops are set
- at multiples of [4mn[24m. If multiple values separated by commas are
- specified, tab stops are set at those positions, and then con-
- tinue with the same spacing as the last two. For example,
- [4m-x9,17[24m will set tabs at positions 9, 17, 25, 33, etc. The
- default for [4mn[24m is 8.
-
- -X or --no-init
- Disables sending the termcap initialization and deinitialization
- strings to the terminal. This is sometimes desirable if the
- deinitialization string does something unnecessary, like clear-
- ing the screen.
-
- -y[4mn[24m or --max-forw-scroll=[4mn[0m
- Specifies a maximum number of lines to scroll forward. If it is
- necessary to scroll forward more than [4mn[24m lines, the screen is
- repainted instead. The -c or -C option may be used to repaint
- from the top of the screen if desired. By default, any forward
- movement causes scrolling.
-
- -[z][4mn[24m or --window=[4mn[0m
- Changes the default scrolling window size to [4mn[24m lines. The
- default is one screenful. The z and w commands can also be used
- to change the window size. The "z" may be omitted for compati-
- bility with some versions of [4mmore.[24m If the number [4mn[24m is negative,
- it indicates [4mn[24m lines less than the current screen size. For
- example, if the screen is 24 lines, [4m-z-4[24m sets the scrolling win-
- dow to 20 lines. If the screen is resized to 40 lines, the
- scrolling window automatically changes to 36 lines.
-
- -[4m"cc[24m or --quotes=[4mcc[0m
- Changes the filename quoting character. This may be necessary
- if you are trying to name a file which contains both spaces and
- quote characters. Followed by a single character, this changes
- the quote character to that character. Filenames containing a
- space should then be surrounded by that character rather than by
- double quotes. Followed by two characters, changes the open
- quote to the first character, and the close quote to the second
- character. Filenames containing a space should then be preceded
- by the open quote character and followed by the close quote
- character. Note that even after the quote characters are
- changed, this option remains -" (a dash followed by a double
- quote).
-
- -~ or --tilde
- Normally lines after end of file are displayed as a single tilde
- (~). This option causes lines after end of file to be displayed
- as blank lines.
-
- -# or --shift
- Specifies the default number of positions to scroll horizontally
- in the RIGHTARROW and LEFTARROW commands. If the number speci-
- fied is zero, it sets the default number of positions to one
- half of the screen width. Alternately, the number may be speci-
- fied as a fraction of the width of the screen, starting with a
- decimal point: .5 is half of the screen width, .3 is three
- tenths of the screen width, and so on. If the number is speci-
- fied as a fraction, the actual number of scroll positions is
- recalculated if the terminal window is resized, so that the
- actual scroll remains at the specified fraction of the screen
- width.
-
- --no-keypad
- Disables sending the keypad initialization and deinitialization
- strings to the terminal. This is sometimes useful if the keypad
- strings make the numeric keypad behave in an undesirable manner.
-
- --follow-name
- Normally, if the input file is renamed while an F command is
- executing, [4mless[24m will continue to display the contents of the
- original file despite its name change. If --follow-name is
- specified, during an F command [4mless[24m will periodically attempt to
- reopen the file by name. If the reopen succeeds and the file is
- a different file from the original (which means that a new file
- has been created with the same name as the original (now
- renamed) file), [4mless[24m will display the contents of that new file.
-
- -- A command line argument of "--" marks the end of option argu-
- ments. Any arguments following this are interpreted as file-
- names. This can be useful when viewing a file whose name begins
- with a "-" or "+".
-
- + If a command line option begins with [1m+[22m, the remainder of that
- option is taken to be an initial command to [4mless.[24m For example,
- +G tells [4mless[24m to start at the end of the file rather than the
- beginning, and +/xyz tells it to start at the first occurrence
- of "xyz" in the file. As a special case, +<number> acts like
- +<number>g; that is, it starts the display at the specified line
- number (however, see the caveat under the "g" command above).
- If the option starts with ++, the initial command applies to
- every file being viewed, not just the first one. The + command
- described previously may also be used to set (or change) an ini-
- tial command for every file.
-
-
-[1mLINE EDITING[0m
- When entering command line at the bottom of the screen (for example, a
- filename for the :e command, or the pattern for a search command), cer-
- tain keys can be used to manipulate the command line. Most commands
- have an alternate form in [ brackets ] which can be used if a key does
- not exist on a particular keyboard. (Note that the forms beginning
- with ESC do not work in some MS-DOS and Windows systems because ESC is
- the line erase character.) Any of these special keys may be entered
- literally by preceding it with the "literal" character, either ^V or
- ^A. A backslash itself may also be entered literally by entering two
- backslashes.
-
- LEFTARROW [ ESC-h ]
- Move the cursor one space to the left.
-
- RIGHTARROW [ ESC-l ]
- Move the cursor one space to the right.
-
- ^LEFTARROW [ ESC-b or ESC-LEFTARROW ]
- (That is, CONTROL and LEFTARROW simultaneously.) Move the cur-
- sor one word to the left.
-
- ^RIGHTARROW [ ESC-w or ESC-RIGHTARROW ]
- (That is, CONTROL and RIGHTARROW simultaneously.) Move the cur-
- sor one word to the right.
-
- HOME [ ESC-0 ]
- Move the cursor to the beginning of the line.
-
- END [ ESC-$ ]
- Move the cursor to the end of the line.
-
- BACKSPACE
- Delete the character to the left of the cursor, or cancel the
- command if the command line is empty.
-
- DELETE or [ ESC-x ]
- Delete the character under the cursor.
-
- ^BACKSPACE [ ESC-BACKSPACE ]
- (That is, CONTROL and BACKSPACE simultaneously.) Delete the
- word to the left of the cursor.
-
- ^DELETE [ ESC-X or ESC-DELETE ]
- (That is, CONTROL and DELETE simultaneously.) Delete the word
- under the cursor.
-
- UPARROW [ ESC-k ]
- Retrieve the previous command line.
-
- DOWNARROW [ ESC-j ]
- Retrieve the next command line.
-
- TAB Complete the partial filename to the left of the cursor. If it
- matches more than one filename, the first match is entered into
- the command line. Repeated TABs will cycle thru the other
- matching filenames. If the completed filename is a directory, a
- "/" is appended to the filename. (On MS-DOS systems, a "\" is
- appended.) The environment variable LESSSEPARATOR can be used
- to specify a different character to append to a directory name.
-
- BACKTAB [ ESC-TAB ]
- Like, TAB, but cycles in the reverse direction thru the matching
- filenames.
-
- ^L Complete the partial filename to the left of the cursor. If it
- matches more than one filename, all matches are entered into the
- command line (if they fit).
-
- ^U (Unix and OS/2) or ESC (MS-DOS)
- Delete the entire command line, or cancel the command if the
- command line is empty. If you have changed your line-kill char-
- acter in Unix to something other than ^U, that character is used
- instead of ^U.
-
-
-[1mKEY BINDINGS[0m
- You may define your own [4mless[24m commands by using the program [4mlesskey[24m (1)
- to create a lesskey file. This file specifies a set of command keys
- and an action associated with each key. You may also use [4mlesskey[24m to
- change the line-editing keys (see LINE EDITING), and to set environment
- variables. If the environment variable LESSKEY is set, [4mless[24m uses that
- as the name of the lesskey file. Otherwise, [4mless[24m looks in a standard
- place for the lesskey file: On Unix systems, [4mless[24m looks for a lesskey
- file called "$HOME/.less". On MS-DOS and Windows systems, [4mless[24m looks
- for a lesskey file called "$HOME/_less", and if it is not found there,
- then looks for a lesskey file called "_less" in any directory specified
- in the PATH environment variable. On OS/2 systems, [4mless[24m looks for a
- lesskey file called "$HOME/less.ini", and if it is not found, then
- looks for a lesskey file called "less.ini" in any directory specified
- in the INIT environment variable, and if it not found there, then looks
- for a lesskey file called "less.ini" in any directory specified in the
- PATH environment variable. See the [4mlesskey[24m manual page for more
- details.
-
- A system-wide lesskey file may also be set up to provide key bindings.
- If a key is defined in both a local lesskey file and in the system-wide
- file, key bindings in the local file take precedence over those in the
- system-wide file. If the environment variable LESSKEY_SYSTEM is set,
- [4mless[24m uses that as the name of the system-wide lesskey file. Otherwise,
- [4mless[24m looks in a standard place for the system-wide lesskey file: On
- Unix systems, the system-wide lesskey file is /usr/local/etc/sysless.
- (However, if [4mless[24m was built with a different sysconf directory than
- /usr/local/etc, that directory is where the sysless file is found.) On
- MS-DOS and Windows systems, the system-wide lesskey file is c:\_sys-
- less. On OS/2 systems, the system-wide lesskey file is c:\sysless.ini.
-
-
-[1mINPUT PREPROCESSOR[0m
- You may define an "input preprocessor" for [4mless.[24m Before [4mless[24m opens a
- file, it first gives your input preprocessor a chance to modify the way
- the contents of the file are displayed. An input preprocessor is sim-
- ply an executable program (or shell script), which writes the contents
- of the file to a different file, called the replacement file. The con-
- tents of the replacement file are then displayed in place of the con-
- tents of the original file. However, it will appear to the user as if
- the original file is opened; that is, [4mless[24m will display the original
- filename as the name of the current file.
-
- An input preprocessor receives one command line argument, the original
- filename, as entered by the user. It should create the replacement
- file, and when finished, print the name of the replacement file to its
- standard output. If the input preprocessor does not output a replace-
- ment filename, [4mless[24m uses the original file, as normal. The input pre-
- processor is not called when viewing standard input. To set up an
- input preprocessor, set the LESSOPEN environment variable to a command
- line which will invoke your input preprocessor. This command line
- should include one occurrence of the string "%s", which will be
- replaced by the filename when the input preprocessor command is
- invoked.
-
- When [4mless[24m closes a file opened in such a way, it will call another pro-
- gram, called the input postprocessor, which may perform any desired
- clean-up action (such as deleting the replacement file created by
- LESSOPEN). This program receives two command line arguments, the orig-
- inal filename as entered by the user, and the name of the replacement
- file. To set up an input postprocessor, set the LESSCLOSE environment
- variable to a command line which will invoke your input postprocessor.
- It may include two occurrences of the string "%s"; the first is
- replaced with the original name of the file and the second with the
- name of the replacement file, which was output by LESSOPEN.
-
- For example, on many Unix systems, these two scripts will allow you to
- keep files in compressed format, but still let [4mless[24m view them directly:
-
- lessopen.sh:
- #! /bin/sh
- case "$1" in
- *.Z) uncompress -
- if [ -s /tmp/less.$$ ]; then
- echo /tmp/less.$$
- else
- rm -f /tmp/less.$$
- fi
- ;;
- esac
-
- lessclose.sh:
- #! /bin/sh
- rm $2
-
- To use these scripts, put them both where they can be executed and set
- LESSOPEN="lessopen.sh %s", and LESSCLOSE="lessclose.sh %s %s". More
- complex LESSOPEN and LESSCLOSE scripts may be written to accept other
- types of compressed files, and so on.
-
- It is also possible to set up an input preprocessor to pipe the file
- data directly to [4mless,[24m rather than putting the data into a replacement
- file. This avoids the need to decompress the entire file before start-
- ing to view it. An input preprocessor that works this way is called an
- input pipe. An input pipe, instead of writing the name of a replace-
- ment file on its standard output, writes the entire contents of the
- replacement file on its standard output. If the input pipe does not
- write any characters on its standard output, then there is no replace-
- ment file and [4mless[24m uses the original file, as normal. To use an input
- pipe, make the first character in the LESSOPEN environment variable a
- vertical bar (|) to signify that the input preprocessor is an input
- pipe.
-
- For example, on many Unix systems, this script will work like the pre-
- vious example scripts:
-
- lesspipe.sh:
- #! /bin/sh
- case "$1" in
- *.Z) uncompress -c $1 2>/dev/null
- ;;
- esac
-
- To use this script, put it where it can be executed and set
- LESSOPEN="|lesspipe.sh %s". When an input pipe is used, a LESSCLOSE
- postprocessor can be used, but it is usually not necessary since there
- is no replacement file to clean up. In this case, the replacement file
- name passed to the LESSCLOSE postprocessor is "-".
-
- For compatibility with previous versions of [4mless,[24m the input preproces-
- sor or pipe is not used if [4mless[24m is viewing standard input. However, if
- the first character of LESSOPEN is a dash (-), the input preprocessor
- is used on standard input as well as other files. In this case, the
- dash is not considered to be part of the preprocessor command. If
- standard input is being viewed, the input preprocessor is passed a file
- name consisting of a single dash. Similarly, if the first two charac-
- ters of LESSOPEN are vertical bar and dash (|-), the input pipe is used
- on standard input as well as other files. Again, in this case the dash
- is not considered to be part of the input pipe command.
-
-
-[1mNATIONAL CHARACTER SETS[0m
- There are three types of characters in the input file:
-
- normal characters
- can be displayed directly to the screen.
-
- control characters
- should not be displayed directly, but are expected to be found
- in ordinary text files (such as backspace and tab).
-
- binary characters
- should not be displayed directly and are not expected to be
- found in text files.
-
- A "character set" is simply a description of which characters are to be
- considered normal, control, and binary. The LESSCHARSET environment
- variable may be used to select a character set. Possible values for
- LESSCHARSET are:
-
- ascii BS, TAB, NL, CR, and formfeed are control characters, all chars
- with values between 32 and 126 are normal, and all others are
- binary.
-
- iso8859
- Selects an ISO 8859 character set. This is the same as ASCII,
- except characters between 160 and 255 are treated as normal
- characters.
-
- latin1 Same as iso8859.
-
- latin9 Same as iso8859.
-
- dos Selects a character set appropriate for MS-DOS.
-
- ebcdic Selects an EBCDIC character set.
-
- IBM-1047
- Selects an EBCDIC character set used by OS/390 Unix Services.
- This is the EBCDIC analogue of latin1. You get similar results
- by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US in your
- environment.
-
- koi8-r Selects a Russian character set.
-
- next Selects a character set appropriate for NeXT computers.
-
- utf-8 Selects the UTF-8 encoding of the ISO 10646 character set.
- UTF-8 is special in that it supports multi-byte characters in
- the input file. It is the only character set that supports
- multi-byte characters.
-
- windows
- Selects a character set appropriate for Microsoft Windows (cp
- 1251).
-
- In rare cases, it may be desired to tailor [4mless[24m to use a character set
- other than the ones definable by LESSCHARSET. In this case, the envi-
- ronment variable LESSCHARDEF can be used to define a character set. It
- should be set to a string where each character in the string represents
- one character in the character set. The character "." is used for a
- normal character, "c" for control, and "b" for binary. A decimal num-
- ber may be used for repetition. For example, "bccc4b." would mean
- character 0 is binary, 1, 2 and 3 are control, 4, 5, 6 and 7 are
- binary, and 8 is normal. All characters after the last are taken to be
- the same as the last, so characters 9 through 255 would be normal.
- (This is an example, and does not necessarily represent any real char-
- acter set.)
-
- This table shows the value of LESSCHARDEF which is equivalent to each
- of the possible values for LESSCHARSET:
-
- ascii 8bcccbcc18b95.b
- dos 8bcccbcc12bc5b95.b.
- ebcdic 5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
- 9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
- IBM-1047 4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
- 191.b
- iso8859 8bcccbcc18b95.33b.
- koi8-r 8bcccbcc18b95.b128.
- latin1 8bcccbcc18b95.33b.
- next 8bcccbcc18b95.bb125.bb
-
- If neither LESSCHARSET nor LESSCHARDEF is set, but any of the strings
- "UTF-8", "UTF8", "utf-8" or "utf8" is found in the LC_ALL, LC_TYPE or
- LANG environment variables, then the default character set is utf-8.
-
- If that string is not found, but your system supports the [4msetlocale[0m
- interface, [4mless[24m will use setlocale to determine the character set.
- setlocale is controlled by setting the LANG or LC_CTYPE environment
- variables.
-
- Finally, if the [4msetlocale[24m interface is also not available, the default
- character set is latin1.
-
- Control and binary characters are displayed in standout (reverse
- video). Each such character is displayed in caret notation if possible
- (e.g. ^A for control-A). Caret notation is used only if inverting the
- 0100 bit results in a normal printable character. Otherwise, the char-
- acter is displayed as a hex number in angle brackets. This format can
- be changed by setting the LESSBINFMT environment variable. LESSBINFMT
- may begin with a "*" and one character to select the display attribute:
- "*k" is blinking, "*d" is bold, "*u" is underlined, "*s" is standout,
- and "*n" is normal. If LESSBINFMT does not begin with a "*", normal
- attribute is assumed. The remainder of LESSBINFMT is a string which
- may include one printf-style escape sequence (a % followed by x, X, o,
- d, etc.). For example, if LESSBINFMT is "*u[%x]", binary characters
- are displayed in underlined hexadecimal surrounded by brackets. The
- default if no LESSBINFMT is specified is "*s<%X>". The default if no
- LESSBINFMT is specified is "*s<%02X>". Warning: the result of expand-
- ing the character via LESSBINFMT must be less than 31 characters.
-
- When the character set is utf-8, the LESSUTFBINFMT environment variable
- acts similarly to LESSBINFMT but it applies to Unicode code points that
- were successfully decoded but are unsuitable for display (e.g., unas-
- signed code points). Its default value is "<U+%04lX>". Note that
- LESSUTFBINFMT and LESSBINFMT share their display attribute setting
- ("*x") so specifying one will affect both; LESSUTFBINFMT is read after
- LESSBINFMT so its setting, if any, will have priority. Problematic
- octets in a UTF-8 file (octets of a truncated sequence, octets of a
- complete but non-shortest form sequence, illegal octets, and stray
- trailing octets) are displayed individually using LESSBINFMT so as to
- facilitate diagnostic of how the UTF-8 file is ill-formed.
-
-
-[1mPROMPTS[0m
- The -P option allows you to tailor the prompt to your preference. The
- string given to the -P option replaces the specified prompt string.
- Certain characters in the string are interpreted specially. The prompt
- mechanism is rather complicated to provide flexibility, but the ordi-
- nary user need not understand the details of constructing personalized
- prompt strings.
-
- A percent sign followed by a single character is expanded according to
- what the following character is:
-
- %b[4mX[24m Replaced by the byte offset into the current input file. The b
- is followed by a single character (shown as [4mX[24m above) which spec-
- ifies the line whose byte offset is to be used. If the charac-
- ter is a "t", the byte offset of the top line in the display is
- used, an "m" means use the middle line, a "b" means use the bot-
- tom line, a "B" means use the line just after the bottom line,
- and a "j" means use the "target" line, as specified by the -j
- option.
-
- %B Replaced by the size of the current input file.
-
- %c Replaced by the column number of the text appearing in the first
- column of the screen.
-
- %d[4mX[24m Replaced by the page number of a line in the input file. The
- line to be used is determined by the [4mX[24m, as with the %b option.
-
- %D Replaced by the number of pages in the input file, or equiva-
- lently, the page number of the last line in the input file.
-
- %E Replaced by the name of the editor (from the VISUAL environment
- variable, or the EDITOR environment variable if VISUAL is not
- defined). See the discussion of the LESSEDIT feature below.
-
- %f Replaced by the name of the current input file.
-
- %i Replaced by the index of the current file in the list of input
- files.
-
- %l[4mX[24m Replaced by the line number of a line in the input file. The
- line to be used is determined by the [4mX[24m, as with the %b option.
-
- %L Replaced by the line number of the last line in the input file.
-
- %m Replaced by the total number of input files.
-
- %p[4mX[24m Replaced by the percent into the current input file, based on
- byte offsets. The line used is determined by the [4mX[24m as with the
- %b option.
-
- %P[4mX[24m Replaced by the percent into the current input file, based on
- line numbers. The line used is determined by the [4mX[24m as with the
- %b option.
-
- %s Same as %B.
-
- %t Causes any trailing spaces to be removed. Usually used at the
- end of the string, but may appear anywhere.
-
- %x Replaced by the name of the next input file in the list.
-
- If any item is unknown (for example, the file size if input is a pipe),
- a question mark is printed instead.
-
- The format of the prompt string can be changed depending on certain
- conditions. A question mark followed by a single character acts like
- an "IF": depending on the following character, a condition is evalu-
- ated. If the condition is true, any characters following the question
- mark and condition character, up to a period, are included in the
- prompt. If the condition is false, such characters are not included.
- A colon appearing between the question mark and the period can be used
- to establish an "ELSE": any characters between the colon and the period
- are included in the string if and only if the IF condition is false.
- Condition characters (which follow a question mark) may be:
-
- ?a True if any characters have been included in the prompt so far.
-
- ?b[4mX[24m True if the byte offset of the specified line is known.
-
- ?B True if the size of current input file is known.
-
- ?c True if the text is horizontally shifted (%c is not zero).
-
- ?d[4mX[24m True if the page number of the specified line is known.
-
- ?e True if at end-of-file.
-
- ?f True if there is an input filename (that is, if input is not a
- pipe).
-
- ?l[4mX[24m True if the line number of the specified line is known.
-
- ?L True if the line number of the last line in the file is known.
-
- ?m True if there is more than one input file.
-
- ?n True if this is the first prompt in a new input file.
-
- ?p[4mX[24m True if the percent into the current input file, based on byte
- offsets, of the specified line is known.
-
- ?P[4mX[24m True if the percent into the current input file, based on line
- numbers, of the specified line is known.
-
- ?s Same as "?B".
-
- ?x True if there is a next input file (that is, if the current
- input file is not the last one).
-
- Any characters other than the special ones (question mark, colon,
- period, percent, and backslash) become literally part of the prompt.
- Any of the special characters may be included in the prompt literally
- by preceding it with a backslash.
-
- Some examples:
-
- ?f%f:Standard input.
-
- This prompt prints the filename, if known; otherwise the string "Stan-
- dard input".
-
- ?f%f .?ltLine %lt:?pt%pt\%:?btByte %bt:-...
-
- This prompt would print the filename, if known. The filename is fol-
- lowed by the line number, if known, otherwise the percent if known,
- otherwise the byte offset if known. Otherwise, a dash is printed.
- Notice how each question mark has a matching period, and how the %
- after the %pt is included literally by escaping it with a backslash.
-
- ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x..%t
-
- This prints the filename if this is the first prompt in a file, fol-
- lowed by the "file N of N" message if there is more than one input
- file. Then, if we are at end-of-file, the string "(END)" is printed
- followed by the name of the next file, if there is one. Finally, any
- trailing spaces are truncated. This is the default prompt. For refer-
- ence, here are the defaults for the other two prompts (-m and -M
- respectively). Each is broken into two lines here for readability
- only.
-
- ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x.:
- ?pB%pB\%:byte %bB?s/%s...%t
-
- ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. :
- byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t
-
- And here is the default message produced by the = command:
-
- ?f%f .?m(file %i of %m) .?ltlines %lt-%lb?L/%L. .
- byte %bB?s/%s. ?e(END) :?pB%pB\%..%t
-
- The prompt expansion features are also used for another purpose: if an
- environment variable LESSEDIT is defined, it is used as the command to
- be executed when the v command is invoked. The LESSEDIT string is
- expanded in the same way as the prompt strings. The default value for
- LESSEDIT is:
-
- %E ?lm+%lm. %f
-
- Note that this expands to the editor name, followed by a + and the line
- number, followed by the file name. If your editor does not accept the
- "+linenumber" syntax, or has other differences in invocation syntax,
- the LESSEDIT variable can be changed to modify this default.
-
-
-[1mSECURITY[0m
- When the environment variable LESSSECURE is set to 1, [4mless[24m runs in a
- "secure" mode. This means these features are disabled:
-
- ! the shell command
-
- | the pipe command
-
- :e the examine command.
-
- v the editing command
-
- s -o log files
-
- -k use of lesskey files
-
- -t use of tags files
-
- metacharacters in filenames, such as *
-
- filename completion (TAB, ^L)
-
- Less can also be compiled to be permanently in "secure" mode.
-
-
-[1mCOMPATIBILITY WITH MORE[0m
- If the environment variable LESS_IS_MORE is set to 1, or if the program
- is invoked via a file link named "more", [4mless[24m behaves (mostly) in con-
- formance with the POSIX "more" command specification. In this mode,
- less behaves differently in these ways:
-
- The -e option works differently. If the -e option is not set, [4mless[0m
- behaves as if the -E option were set. If the -e option is set, [4mless[0m
- behaves as if the -e and -F options were set.
-
- The -m option works differently. If the -m option is not set, the
- medium prompt is used, and it is prefixed with the string "--More--".
- If the -m option is set, the short prompt is used.
-
- The -n option acts like the -z option. The normal behavior of the -n
- option is unavailable in this mode.
-
- The parameter to the -p option is taken to be a [4mless[24m command rather
- than a search pattern.
-
- The LESS environment variable is ignored, and the MORE environment
- variable is used in its place.
-
-
-[1mENVIRONMENT VARIABLES[0m
- Environment variables may be specified either in the system environment
- as usual, or in a [4mlesskey[24m (1) file. If environment variables are
- defined in more than one place, variables defined in a local lesskey
- file take precedence over variables defined in the system environment,
- which take precedence over variables defined in the system-wide lesskey
- file.
-
- COLUMNS
- Sets the number of columns on the screen. Takes precedence over
- the number of columns specified by the TERM variable. (But if
- you have a windowing system which supports TIOCGWINSZ or
- WIOCGETD, the window system's idea of the screen size takes
- precedence over the LINES and COLUMNS environment variables.)
-
- EDITOR The name of the editor (used for the v command).
-
- HOME Name of the user's home directory (used to find a lesskey file
- on Unix and OS/2 systems).
-
- HOMEDRIVE, HOMEPATH
- Concatenation of the HOMEDRIVE and HOMEPATH environment vari-
- ables is the name of the user's home directory if the HOME vari-
- able is not set (only in the Windows version).
-
- INIT Name of the user's init directory (used to find a lesskey file
- on OS/2 systems).
-
- LANG Language for determining the character set.
-
- LC_CTYPE
- Language for determining the character set.
-
- LESS Options which are passed to [4mless[24m automatically.
-
- LESSANSIENDCHARS
- Characters which may end an ANSI color escape sequence (default
- "m").
-
- LESSANSIMIDCHARS

+
+[1mDESCRIPTION[0m
+ [4mLess[24m is a program similar to [4mmore[24m (1), but which allows backward move-
+ ment in the file as well as forward movement. Also, [4mless[24m does not have
+ to read the entire input file before starting, so with large input
+ files it starts up faster than text editors like [4mvi[24m (1). [4mLess[24m uses
+ termcap (or terminfo on some systems), so it can run on a variety of
+ terminals. There is even limited support for hardcopy terminals. (On
+ a hardcopy terminal, lines which should be printed at the top of the
+ screen are prefixed with a caret.)
+
+ Commands are based on both [4mmore[24m and [4mvi.[24m Commands may be preceded by a
+ decimal number, called N in the descriptions below. The number is used
+ by some commands, as indicated.
+
+
+[1mCOMMANDS[0m
+ In the following descriptions, ^X means control-X. ESC stands for the
+ ESCAPE key; for example ESC-v means the two character sequence
+ "ESCAPE", then "v".
+
+ h or H Help: display a summary of these commands. If you forget all
+ the other commands, remember this one.
+
+ SPACE or ^V or f or ^F
+ Scroll forward N lines, default one window (see option -z
+ below). If N is more than the screen size, only the final
+ screenful is displayed. Warning: some systems use ^V as a spe-
+ cial literalization character.
+
+ z Like SPACE, but if N is specified, it becomes the new window
+ size.
+
+ ESC-SPACE
+ Like SPACE, but scrolls a full screenful, even if it reaches
+ end-of-file in the process.
+
+ ENTER or RETURN or ^N or e or ^E or j or ^J
+ Scroll forward N lines, default 1. The entire N lines are dis-
+ played, even if N is more than the screen size.
+
+ d or ^D
+ Scroll forward N lines, default one half of the screen size. If
+ N is specified, it becomes the new default for subsequent d and
+ u commands.
+
+ b or ^B or ESC-v
+ Scroll backward N lines, default one window (see option -z
+ below). If N is more than the screen size, only the final
+ screenful is displayed.
+
+ w Like ESC-v, but if N is specified, it becomes the new window
+ size.
+
+ y or ^Y or ^P or k or ^K
+ Scroll backward N lines, default 1. The entire N lines are dis-
+ played, even if N is more than the screen size. Warning: some
+ systems use ^Y as a special job control character.
+
+ u or ^U
+ Scroll backward N lines, default one half of the screen size.
+ If N is specified, it becomes the new default for subsequent d
+ and u commands.
+
+ ESC-) or RIGHTARROW
+ Scroll horizontally right N characters, default half the screen
+ width (see the -# option). If a number N is specified, it
+ becomes the default for future RIGHTARROW and LEFTARROW com-
+ mands. While the text is scrolled, it acts as though the -S
+ option (chop lines) were in effect.
+
+ ESC-( or LEFTARROW
+ Scroll horizontally left N characters, default half the screen
+ width (see the -# option). If a number N is specified, it
+ becomes the default for future RIGHTARROW and LEFTARROW com-
+ mands.
+
+ r or ^R or ^L
+ Repaint the screen.
+
+ R Repaint the screen, discarding any buffered input. Useful if
+ the file is changing while it is being viewed.
+
+ F Scroll forward, and keep trying to read when the end of file is
+ reached. Normally this command would be used when already at
+ the end of the file. It is a way to monitor the tail of a file
+ which is growing while it is being viewed. (The behavior is
+ similar to the "tail -f" command.)
+
+ ESC-F Like F, but as soon as a line is found which matches the last
+ search pattern, the terminal bell is rung and forward scrolling
+ stops.
+
+ g or < or ESC-<
+ Go to line N in the file, default 1 (beginning of file). (Warn-
+ ing: this may be slow if N is large.)
+
+ G or > or ESC->
+ Go to line N in the file, default the end of the file. (Warn-
+ ing: this may be slow if N is large, or if N is not specified
+ and standard input, rather than a file, is being read.)
+
+ p or % Go to a position N percent into the file. N should be between 0
+ and 100, and may contain a decimal point.
+
+ P Go to the line containing byte offset N in the file.
+
+ { If a left curly bracket appears in the top line displayed on the
+ screen, the { command will go to the matching right curly
+ bracket. The matching right curly bracket is positioned on the
+ bottom line of the screen. If there is more than one left curly
+ bracket on the top line, a number N may be used to specify the
+ N-th bracket on the line.
+
+ } If a right curly bracket appears in the bottom line displayed on
+ the screen, the } command will go to the matching left curly
+ bracket. The matching left curly bracket is positioned on the
+ top line of the screen. If there is more than one right curly
+ bracket on the top line, a number N may be used to specify the
+ N-th bracket on the line.
+
+ ( Like {, but applies to parentheses rather than curly brackets.
+
+ ) Like }, but applies to parentheses rather than curly brackets.
+
+ [ Like {, but applies to square brackets rather than curly brack-
+ ets.
+
+ ] Like }, but applies to square brackets rather than curly brack-
+ ets.
+
+ ESC-^F Followed by two characters, acts like {, but uses the two char-
+ acters as open and close brackets, respectively. For example,
+ "ESC ^F < >" could be used to go forward to the > which matches
+ the < in the top displayed line.
+
+ ESC-^B Followed by two characters, acts like }, but uses the two char-
+ acters as open and close brackets, respectively. For example,
+ "ESC ^B < >" could be used to go backward to the < which matches
+ the > in the bottom displayed line.
+
+ m Followed by any lowercase letter, marks the current position
+ with that letter.
+
+ ' (Single quote.) Followed by any lowercase letter, returns to
+ the position which was previously marked with that letter. Fol-
+ lowed by another single quote, returns to the position at which
+ the last "large" movement command was executed. Followed by a ^
+ or $, jumps to the beginning or end of the file respectively.
+ Marks are preserved when a new file is examined, so the ' com-
+ mand can be used to switch between input files.
+
+ ^X^X Same as single quote.
+
+ /pattern
+ Search forward in the file for the N-th line containing the pat-
+ tern. N defaults to 1. The pattern is a regular expression, as
+ recognized by the regular expression library supplied by your
+ system. The search starts at the first line displayed (but see
+ the -a and -j options, which change this).
+
+ Certain characters are special if entered at the beginning of
+ the pattern; they modify the type of search rather than become
+ part of the pattern:
+
+ ^N or !
+ Search for lines which do NOT match the pattern.
+
+ ^E or *
+ Search multiple files. That is, if the search reaches
+ the END of the current file without finding a match, the
+ search continues in the next file in the command line
+ list.
+
+ ^F or @
+ Begin the search at the first line of the FIRST file in
+ the command line list, regardless of what is currently
+ displayed on the screen or the settings of the -a or -j
+ options.
+
+ ^K Highlight any text which matches the pattern on the cur-
+ rent screen, but don't move to the first match (KEEP cur-
+ rent position).
+
+ ^R Don't interpret regular expression metacharacters; that
+ is, do a simple textual comparison.
+
+ ?pattern
+ Search backward in the file for the N-th line containing the
+ pattern. The search starts at the line immediately before the
+ top line displayed.
+
+ Certain characters are special as in the / command:
+
+ ^N or !
+ Search for lines which do NOT match the pattern.
+
+ ^E or *
+ Search multiple files. That is, if the search reaches
+ the beginning of the current file without finding a
+ match, the search continues in the previous file in the
+ command line list.
+
+ ^F or @
+ Begin the search at the last line of the last file in the
+ command line list, regardless of what is currently dis-
+ played on the screen or the settings of the -a or -j
+ options.
+
+ ^K As in forward searches.
+
+ ^R As in forward searches.
+
+ ESC-/pattern
+ Same as "/*".
+
+ ESC-?pattern
+ Same as "?*".
+
+ n Repeat previous search, for N-th line containing the last pat-
+ tern. If the previous search was modified by ^N, the search is
+ made for the N-th line NOT containing the pattern. If the pre-
+ vious search was modified by ^E, the search continues in the
+ next (or previous) file if not satisfied in the current file.
+ If the previous search was modified by ^R, the search is done
+ without using regular expressions. There is no effect if the
+ previous search was modified by ^F or ^K.
+
+ N Repeat previous search, but in the reverse direction.
+
+ ESC-n Repeat previous search, but crossing file boundaries. The
+ effect is as if the previous search were modified by *.
+
+ ESC-N Repeat previous search, but in the reverse direction and cross-
+ ing file boundaries.
+
+ ESC-u Undo search highlighting. Turn off highlighting of strings
+ matching the current search pattern. If highlighting is already
+ off because of a previous ESC-u command, turn highlighting back
+ on. Any search command will also turn highlighting back on.
+ (Highlighting can also be disabled by toggling the -G option; in
+ that case search commands do not turn highlighting back on.)
+
+ &pattern
+ Display only lines which match the pattern; lines which do not
+ match the pattern are not displayed. If pattern is empty (if
+ you type & immediately followed by ENTER), any filtering is
+ turned off, and all lines are displayed. While filtering is in
+ effect, an ampersand is displayed at the beginning of the
+ prompt, as a reminder that some lines in the file may be hidden.
+
+ Certain characters are special as in the / command:
+
+ ^N or !
+ Display only lines which do NOT match the pattern.
+
+ ^R Don't interpret regular expression metacharacters; that
+ is, do a simple textual comparison.
+
+ :e [filename]
+ Examine a new file. If the filename is missing, the "current"
+ file (see the :n and :p commands below) from the list of files
+ in the command line is re-examined. A percent sign (%) in the
+ filename is replaced by the name of the current file. A pound
+ sign (#) is replaced by the name of the previously examined
+ file. However, two consecutive percent signs are simply
+ replaced with a single percent sign. This allows you to enter a
+ filename that contains a percent sign in the name. Similarly,
+ two consecutive pound signs are replaced with a single pound
+ sign. The filename is inserted into the command line list of
+ files so that it can be seen by subsequent :n and :p commands.
+ If the filename consists of several files, they are all inserted
+ into the list of files and the first one is examined. If the
+ filename contains one or more spaces, the entire filename should
+ be enclosed in double quotes (also see the -" option).
+
+ ^X^V or E
+ Same as :e. Warning: some systems use ^V as a special literal-
+ ization character. On such systems, you may not be able to use
+ ^V.
+
+ :n Examine the next file (from the list of files given in the com-
+ mand line). If a number N is specified, the N-th next file is
+ examined.
+
+ :p Examine the previous file in the command line list. If a number
+ N is specified, the N-th previous file is examined.
+
+ :x Examine the first file in the command line list. If a number N
+ is specified, the N-th file in the list is examined.
+
+ :d Remove the current file from the list of files.
+
+ t Go to the next tag, if there were more than one matches for the
+ current tag. See the -t option for more details about tags.
+
+ T Go to the previous tag, if there were more than one matches for
+ the current tag.
+
+ = or ^G or :f
+ Prints some information about the file being viewed, including
+ its name and the line number and byte offset of the bottom line
+ being displayed. If possible, it also prints the length of the
+ file, the number of lines in the file and the percent of the
+ file above the last displayed line.
+
+ - Followed by one of the command line option letters (see OPTIONS
+ below), this will change the setting of that option and print a
+ message describing the new setting. If a ^P (CONTROL-P) is
+ entered immediately after the dash, the setting of the option is
+ changed but no message is printed. If the option letter has a
+ numeric value (such as -b or -h), or a string value (such as -P
+ or -t), a new value may be entered after the option letter. If
+ no new value is entered, a message describing the current set-
+ ting is printed and nothing is changed.
+
+ -- Like the - command, but takes a long option name (see OPTIONS
+ below) rather than a single option letter. You must press ENTER
+ or RETURN after typing the option name. A ^P immediately after
+ the second dash suppresses printing of a message describing the
+ new setting, as in the - command.
+
+ -+ Followed by one of the command line option letters this will
+ reset the option to its default setting and print a message
+ describing the new setting. (The "-+[4mX[24m" command does the same
+ thing as "-+[4mX[24m" on the command line.) This does not work for
+ string-valued options.
+
+ --+ Like the -+ command, but takes a long option name rather than a
+ single option letter.
+
+ -! Followed by one of the command line option letters, this will
+ reset the option to the "opposite" of its default setting and
+ print a message describing the new setting. This does not work
+ for numeric or string-valued options.
+
+ --! Like the -! command, but takes a long option name rather than a
+ single option letter.
+
+ _ (Underscore.) Followed by one of the command line option let-
+ ters, this will print a message describing the current setting
+ of that option. The setting of the option is not changed.
+
+ __ (Double underscore.) Like the _ (underscore) command, but takes
+ a long option name rather than a single option letter. You must
+ press ENTER or RETURN after typing the option name.
+
+ +cmd Causes the specified cmd to be executed each time a new file is
+ examined. For example, +G causes [4mless[24m to initially display each
+ file starting at the end rather than the beginning.
+
+ V Prints the version number of [4mless[24m being run.
+
+ q or Q or :q or :Q or ZZ
+ Exits [4mless.[0m
+
+ The following four commands may or may not be valid, depending on your
+ particular installation.
+
+ v Invokes an editor to edit the current file being viewed. The
+ editor is taken from the environment variable VISUAL if defined,
+ or EDITOR if VISUAL is not defined, or defaults to "vi" if nei-
+ ther VISUAL nor EDITOR is defined. See also the discussion of
+ LESSEDIT under the section on PROMPTS below.
+
+ ! shell-command
+ Invokes a shell to run the shell-command given. A percent sign
+ (%) in the command is replaced by the name of the current file.
+ A pound sign (#) is replaced by the name of the previously exam-
+ ined file. "!!" repeats the last shell command. "!" with no
+ shell command simply invokes a shell. On Unix systems, the
+ shell is taken from the environment variable SHELL, or defaults
+ to "sh". On MS-DOS and OS/2 systems, the shell is the normal
+ command processor.
+
+ | <m> shell-command
+ <m> represents any mark letter. Pipes a section of the input
+ file to the given shell command. The section of the file to be
+ piped is between the first line on the current screen and the
+ position marked by the letter. <m> may also be ^ or $ to indi-
+ cate beginning or end of file respectively. If <m> is . or new-
+ line, the current screen is piped.
+
+ s filename
+ Save the input to a file. This only works if the input is a
+ pipe, not an ordinary file.
+
+[1mOPTIONS[0m
+ Command line options are described below. Most options may be changed
+ while [4mless[24m is running, via the "-" command.
+
+ Most options may be given in one of two forms: either a dash followed
+ by a single letter, or two dashes followed by a long option name. A
+ long option name may be abbreviated as long as the abbreviation is
+ unambiguous. For example, --quit-at-eof may be abbreviated --quit, but
+ not --qui, since both --quit-at-eof and --quiet begin with --qui. Some
+ long option names are in uppercase, such as --QUIT-AT-EOF, as distinct
+ from --quit-at-eof. Such option names need only have their first let-
+ ter capitalized; the remainder of the name may be in either case. For
+ example, --Quit-at-eof is equivalent to --QUIT-AT-EOF.
+
+ Options are also taken from the environment variable "LESS". For exam-
+ ple, to avoid typing "less -options ..." each time [4mless[24m is invoked, you
+ might tell [4mcsh:[0m
+
+ setenv LESS "-options"
+
+ or if you use [4msh:[0m
+
+ LESS="-options"; export LESS
+
+ On MS-DOS, you don't need the quotes, but you should replace any per-
+ cent signs in the options string by double percent signs.
+
+ The environment variable is parsed before the command line, so command
+ line options override the LESS environment variable. If an option
+ appears in the LESS variable, it can be reset to its default value on
+ the command line by beginning the command line option with "-+".
+
+ Some options like -k or -D require a string to follow the option let-
+ ter. The string for that option is considered to end when a dollar
+ sign ($) is found. For example, you can set two -D options on MS-DOS
+ like this:
+
+ LESS="Dn9.1$Ds4.1"
+
+ If the --use-backslash option appears earlier in the options, then a
+ dollar sign or backslash may be included literally in an option string
+ by preceding it with a backslash. If the --use-backslash option is not
+ in effect, then backslashes are not treated specially, and there is no
+ way to include a dollar sign in the option string.
+
+ -? or --help
+ This option displays a summary of the commands accepted by [4mless[0m
+ (the same as the h command). (Depending on how your shell
+ interprets the question mark, it may be necessary to quote the
+ question mark, thus: "-\?".)
+
+ -a or --search-skip-screen
+ By default, forward searches start at the top of the displayed
+ screen and backwards searches start at the bottom of the dis-
+ played screen (except for repeated searches invoked by the n or
+ N commands, which start after or before the "target" line
+ respectively; see the -j option for more about the target line).
+ The -a option causes forward searches to instead start at the
+ bottom of the screen and backward searches to start at the top
+ of the screen, thus skipping all lines displayed on the screen.
+
+ -A or --SEARCH-SKIP-SCREEN
+ Causes all forward searches (not just non-repeated searches) to
+ start just after the target line, and all backward searches to
+ start just before the target line. Thus, forward searches will
+ skip part of the displayed screen (from the first line up to and
+ including the target line). Similarly backwards searches will
+ skip the displayed screen from the last line up to and including
+ the target line. This was the default behavior in less versions
+ prior to 441.
+
+ -b[4mn[24m or --buffers=[4mn[0m
+ Specifies the amount of buffer space [4mless[24m will use for each
+ file, in units of kilobytes (1024 bytes). By default 64K of
+ buffer space is used for each file (unless the file is a pipe;
+ see the -B option). The -b option specifies instead that [4mn[0m
+ kilobytes of buffer space should be used for each file. If [4mn[24m is
+ -1, buffer space is unlimited; that is, the entire file can be
+ read into memory.
+
+ -B or --auto-buffers
+ By default, when data is read from a pipe, buffers are allocated
+ automatically as needed. If a large amount of data is read from
+ the pipe, this can cause a large amount of memory to be allo-
+ cated. The -B option disables this automatic allocation of buf-
+ fers for pipes, so that only 64K (or the amount of space speci-
+ fied by the -b option) is used for the pipe. Warning: use of -B
+ can result in erroneous display, since only the most recently
+ viewed part of the piped data is kept in memory; any earlier
+ data is lost.
+
+ -c or --clear-screen
+ Causes full screen repaints to be painted from the top line
+ down. By default, full screen repaints are done by scrolling
+ from the bottom of the screen.
+
+ -C or --CLEAR-SCREEN
+ Same as -c, for compatibility with older versions of [4mless.[0m
+
+ -d or --dumb
+ The -d option suppresses the error message normally displayed if
+ the terminal is dumb; that is, lacks some important capability,
+ such as the ability to clear the screen or scroll backward. The
+ -d option does not otherwise change the behavior of [4mless[24m on a
+ dumb terminal.
+
+ -D[1mx[4m[22mcolor[24m or --color=[1mx[4m[22mcolor[0m
+ [MS-DOS only] Sets the color of the text displayed. [1mx [22mis a sin-
+ gle character which selects the type of text whose color is
+ being set: n=normal, s=standout, d=bold, u=underlined, k=blink.
+ [4mcolor[24m is a pair of numbers separated by a period. The first
+ number selects the foreground color and the second selects the
+ background color of the text. A single number [4mN[24m is the same as
+ [4mN.M[24m, where [4mM[24m is the normal background color.
+
+
+ -e or --quit-at-eof
+ Causes [4mless[24m to automatically exit the second time it reaches
+ end-of-file. By default, the only way to exit [4mless[24m is via the
+ "q" command.
+
+ -E or --QUIT-AT-EOF
+ Causes [4mless[24m to automatically exit the first time it reaches end-
+ of-file.
+
+ -f or --force
+ Forces non-regular files to be opened. (A non-regular file is a
+ directory or a device special file.) Also suppresses the warn-
+ ing message when a binary file is opened. By default, [4mless[24m will
+ refuse to open non-regular files. Note that some operating sys-
+ tems will not allow directories to be read, even if -f is set.
+
+ -F or --quit-if-one-screen
+ Causes [4mless[24m to automatically exit if the entire file can be dis-
+ played on the first screen.
+
+ -g or --hilite-search
+ Normally, [4mless[24m will highlight ALL strings which match the last
+ search command. The -g option changes this behavior to high-
+ light only the particular string which was found by the last
+ search command. This can cause [4mless[24m to run somewhat faster than
+ the default.
+
+ -G or --HILITE-SEARCH
+ The -G option suppresses all highlighting of strings found by
+ search commands.
+
+ -h[4mn[24m or --max-back-scroll=[4mn[0m
+ Specifies a maximum number of lines to scroll backward. If it
+ is necessary to scroll backward more than [4mn[24m lines, the screen is
+ repainted in a forward direction instead. (If the terminal does
+ not have the ability to scroll backward, -h0 is implied.)
+
+ -i or --ignore-case
+ Causes searches to ignore case; that is, uppercase and lowercase
+ are considered identical. This option is ignored if any upper-
+ case letters appear in the search pattern; in other words, if a
+ pattern contains uppercase letters, then that search does not
+ ignore case.
+
+ -I or --IGNORE-CASE
+ Like -i, but searches ignore case even if the pattern contains
+ uppercase letters.
+
+ -j[4mn[24m or --jump-target=[4mn[0m
+ Specifies a line on the screen where the "target" line is to be
+ positioned. The target line is the line specified by any com-
+ mand to search for a pattern, jump to a line number, jump to a
+ file percentage or jump to a tag. The screen line may be speci-
+ fied by a number: the top line on the screen is 1, the next is
+ 2, and so on. The number may be negative to specify a line rel-
+ ative to the bottom of the screen: the bottom line on the screen
+ is -1, the second to the bottom is -2, and so on. Alternately,
+ the screen line may be specified as a fraction of the height of
+ the screen, starting with a decimal point: .5 is in the middle
+ of the screen, .3 is three tenths down from the first line, and
+ so on. If the line is specified as a fraction, the actual line
+ number is recalculated if the terminal window is resized, so
+ that the target line remains at the specified fraction of the
+ screen height. If any form of the -j option is used, forward
+ searches begin at the line immediately after the target line,
+ and backward searches begin at the target line, unless changed
+ by -a or -A. For example, if "-j4" is used, the target line is
+ the fourth line on the screen, so forward searches begin at the
+ fifth line on the screen.
+
+ -J or --status-column
+ Displays a status column at the left edge of the screen. The
+ status column shows the lines that matched the current search.
+ The status column is also used if the -w or -W option is in
+ effect.
+
+ -k[4mfilename[24m or --lesskey-file=[4mfilename[0m
+ Causes [4mless[24m to open and interpret the named file as a [4mlesskey[0m
+ (1) file. Multiple -k options may be specified. If the LESSKEY
+ or LESSKEY_SYSTEM environment variable is set, or if a lesskey
+ file is found in a standard place (see KEY BINDINGS), it is also
+ used as a [4mlesskey[24m file.
+
+ -K or --quit-on-intr
+ Causes [4mless[24m to exit immediately (with status 2) when an inter-
+ rupt character (usually ^C) is typed. Normally, an interrupt
+ character causes [4mless[24m to stop whatever it is doing and return to
+ its command prompt. Note that use of this option makes it
+ impossible to return to the command prompt from the "F" command.
+
+ -L or --no-lessopen
+ Ignore the LESSOPEN environment variable (see the INPUT PRE-
+ PROCESSOR section below). This option can be set from within
+ [4mless[24m, but it will apply only to files opened subsequently, not
+ to the file which is currently open.
+
+ -m or --long-prompt
+ Causes [4mless[24m to prompt verbosely (like [4mmore[24m), with the percent
+ into the file. By default, [4mless[24m prompts with a colon.
+
+ -M or --LONG-PROMPT
+ Causes [4mless[24m to prompt even more verbosely than [4mmore.[0m
+
+ -n or --line-numbers
+ Suppresses line numbers. The default (to use line numbers) may
+ cause [4mless[24m to run more slowly in some cases, especially with a
+ very large input file. Suppressing line numbers with the -n
+ option will avoid this problem. Using line numbers means: the
+ line number will be displayed in the verbose prompt and in the =
+ command, and the v command will pass the current line number to
+ the editor (see also the discussion of LESSEDIT in PROMPTS
+ below).
+
+ -N or --LINE-NUMBERS
+ Causes a line number to be displayed at the beginning of each
+ line in the display.
+
+ -o[4mfilename[24m or --log-file=[4mfilename[0m
+ Causes [4mless[24m to copy its input to the named file as it is being
+ viewed. This applies only when the input file is a pipe, not an
+ ordinary file. If the file already exists, [4mless[24m will ask for
+ confirmation before overwriting it.
+
+ -O[4mfilename[24m or --LOG-FILE=[4mfilename[0m
+ The -O option is like -o, but it will overwrite an existing file
+ without asking for confirmation.
+
+ If no log file has been specified, the -o and -O options can be
+ used from within [4mless[24m to specify a log file. Without a file
+ name, they will simply report the name of the log file. The "s"
+ command is equivalent to specifying -o from within [4mless.[0m
+
+ -p[4mpattern[24m or --pattern=[4mpattern[0m
+ The -p option on the command line is equivalent to specifying
+ +/[4mpattern[24m; that is, it tells [4mless[24m to start at the first occur-
+ rence of [4mpattern[24m in the file.
+
+ -P[4mprompt[24m or --prompt=[4mprompt[0m
+ Provides a way to tailor the three prompt styles to your own
+ preference. This option would normally be put in the LESS envi-
+ ronment variable, rather than being typed in with each [4mless[24m com-
+ mand. Such an option must either be the last option in the LESS
+ variable, or be terminated by a dollar sign. -Ps followed by a
+ string changes the default (short) prompt to that string. -Pm
+ changes the medium (-m) prompt. -PM changes the long (-M)
+ prompt. -Ph changes the prompt for the help screen. -P=
+ changes the message printed by the = command. -Pw changes the
+ message printed while waiting for data (in the F command). All
+ prompt strings consist of a sequence of letters and special
+ escape sequences. See the section on PROMPTS for more details.
+
+ -q or --quiet or --silent
+ Causes moderately "quiet" operation: the terminal bell is not
+ rung if an attempt is made to scroll past the end of the file or
+ before the beginning of the file. If the terminal has a "visual
+ bell", it is used instead. The bell will be rung on certain
+ other errors, such as typing an invalid character. The default
+ is to ring the terminal bell in all such cases.
+
+ -Q or --QUIET or --SILENT
+ Causes totally "quiet" operation: the terminal bell is never
+ rung.
+
+ -r or --raw-control-chars
+ Causes "raw" control characters to be displayed. The default is
+ to display control characters using the caret notation; for
+ example, a control-A (octal 001) is displayed as "^A". Warning:
+ when the -r option is used, [4mless[24m cannot keep track of the actual
+ appearance of the screen (since this depends on how the screen
+ responds to each type of control character). Thus, various dis-
+ play problems may result, such as long lines being split in the
+ wrong place.
+
+ -R or --RAW-CONTROL-CHARS
+ Like -r, but only ANSI "color" escape sequences are output in
+ "raw" form. Unlike -r, the screen appearance is maintained cor-
+ rectly in most cases. ANSI "color" escape sequences are
+ sequences of the form:
+
+ ESC [ ... m
+
+ where the "..." is zero or more color specification characters
+ For the purpose of keeping track of screen appearance, ANSI
+ color escape sequences are assumed to not move the cursor. You
+ can make [4mless[24m think that characters other than "m" can end ANSI
+ color escape sequences by setting the environment variable
+ LESSANSIENDCHARS to the list of characters which can end a color
+ escape sequence. And you can make [4mless[24m think that characters
+ other than the standard ones may appear between the ESC and the
+ m by setting the environment variable LESSANSIMIDCHARS to the
+ list of characters which can appear.
+
+ -s or --squeeze-blank-lines
+ Causes consecutive blank lines to be squeezed into a single
+ blank line. This is useful when viewing [4mnroff[24m output.
+
+ -S or --chop-long-lines
+ Causes lines longer than the screen width to be chopped (trun-
+ cated) rather than wrapped. That is, the portion of a long line
+ that does not fit in the screen width is not shown. The default
+ is to wrap long lines; that is, display the remainder on the
+ next line.
+
+ -t[4mtag[24m or --tag=[4mtag[0m
+ The -t option, followed immediately by a TAG, will edit the file
+ containing that tag. For this to work, tag information must be
+ available; for example, there may be a file in the current
+ directory called "tags", which was previously built by [4mctags[24m (1)
+ or an equivalent command. If the environment variable LESSGLOB-
+ ALTAGS is set, it is taken to be the name of a command compati-
+ ble with [4mglobal[24m (1), and that command is executed to find the
+ tag. (See http://www.gnu.org/software/global/global.html). The
+ -t option may also be specified from within [4mless[24m (using the -
+ command) as a way of examining a new file. The command ":t" is
+ equivalent to specifying -t from within [4mless.[0m
+
+ -T[4mtagsfile[24m or --tag-file=[4mtagsfile[0m
+ Specifies a tags file to be used instead of "tags".
+
+ -u or --underline-special
+ Causes backspaces and carriage returns to be treated as print-
+ able characters; that is, they are sent to the terminal when
+ they appear in the input.
+
+ -U or --UNDERLINE-SPECIAL
+ Causes backspaces, tabs and carriage returns to be treated as
+ control characters; that is, they are handled as specified by
+ the -r option.
+
+ By default, if neither -u nor -U is given, backspaces which
+ appear adjacent to an underscore character are treated spe-
+ cially: the underlined text is displayed using the terminal's
+ hardware underlining capability. Also, backspaces which appear
+ between two identical characters are treated specially: the
+ overstruck text is printed using the terminal's hardware bold-
+ face capability. Other backspaces are deleted, along with the
+ preceding character. Carriage returns immediately followed by a
+ newline are deleted. Other carriage returns are handled as
+ specified by the -r option. Text which is overstruck or under-
+ lined can be searched for if neither -u nor -U is in effect.
+
+ -V or --version
+ Displays the version number of [4mless.[0m
+
+ -w or --hilite-unread
+ Temporarily highlights the first "new" line after a forward
+ movement of a full page. The first "new" line is the line imme-
+ diately following the line previously at the bottom of the
+ screen. Also highlights the target line after a g or p command.
+ The highlight is removed at the next command which causes move-
+ ment. The entire line is highlighted, unless the -J option is
+ in effect, in which case only the status column is highlighted.
+
+ -W or --HILITE-UNREAD
+ Like -w, but temporarily highlights the first new line after any
+ forward movement command larger than one line.
+
+ -x[4mn[24m,... or --tabs=[4mn[24m,...
+ Sets tab stops. If only one [4mn[24m is specified, tab stops are set
+ at multiples of [4mn[24m. If multiple values separated by commas are
+ specified, tab stops are set at those positions, and then con-
+ tinue with the same spacing as the last two. For example,
+ [4m-x9,17[24m will set tabs at positions 9, 17, 25, 33, etc. The
+ default for [4mn[24m is 8.
+
+ -X or --no-init
+ Disables sending the termcap initialization and deinitialization
+ strings to the terminal. This is sometimes desirable if the
+ deinitialization string does something unnecessary, like clear-
+ ing the screen.
+
+ -y[4mn[24m or --max-forw-scroll=[4mn[0m
+ Specifies a maximum number of lines to scroll forward. If it is
+ necessary to scroll forward more than [4mn[24m lines, the screen is
+ repainted instead. The -c or -C option may be used to repaint
+ from the top of the screen if desired. By default, any forward
+ movement causes scrolling.
+
+ -[z][4mn[24m or --window=[4mn[0m
+ Changes the default scrolling window size to [4mn[24m lines. The
+ default is one screenful. The z and w commands can also be used
+ to change the window size. The "z" may be omitted for compati-
+ bility with some versions of [4mmore.[24m If the number [4mn[24m is negative,
+ it indicates [4mn[24m lines less than the current screen size. For
+ example, if the screen is 24 lines, [4m-z-4[24m sets the scrolling win-
+ dow to 20 lines. If the screen is resized to 40 lines, the
+ scrolling window automatically changes to 36 lines.
+
+ -[4m"cc[24m or --quotes=[4mcc[0m
+ Changes the filename quoting character. This may be necessary
+ if you are trying to name a file which contains both spaces and
+ quote characters. Followed by a single character, this changes
+ the quote character to that character. Filenames containing a
+ space should then be surrounded by that character rather than by
+ double quotes. Followed by two characters, changes the open
+ quote to the first character, and the close quote to the second
+ character. Filenames containing a space should then be preceded
+ by the open quote character and followed by the close quote
+ character. Note that even after the quote characters are
+ changed, this option remains -" (a dash followed by a double
+ quote).
+
+ -~ or --tilde
+ Normally lines after end of file are displayed as a single tilde
+ (~). This option causes lines after end of file to be displayed
+ as blank lines.
+
+ -# or --shift
+ Specifies the default number of positions to scroll horizontally
+ in the RIGHTARROW and LEFTARROW commands. If the number speci-
+ fied is zero, it sets the default number of positions to one
+ half of the screen width. Alternately, the number may be speci-
+ fied as a fraction of the width of the screen, starting with a
+ decimal point: .5 is half of the screen width, .3 is three
+ tenths of the screen width, and so on. If the number is speci-
+ fied as a fraction, the actual number of scroll positions is
+ recalculated if the terminal window is resized, so that the
+ actual scroll remains at the specified fraction of the screen
+ width.
+
+ --follow-name
+ Normally, if the input file is renamed while an F command is
+ executing, [4mless[24m will continue to display the contents of the
+ original file despite its name change. If --follow-name is
+ specified, during an F command [4mless[24m will periodically attempt to
+ reopen the file by name. If the reopen succeeds and the file is
+ a different file from the original (which means that a new file
+ has been created with the same name as the original (now
+ renamed) file), [4mless[24m will display the contents of that new file.
+
+ --no-keypad
+ Disables sending the keypad initialization and deinitialization
+ strings to the terminal. This is sometimes useful if the keypad
+ strings make the numeric keypad behave in an undesirable manner.
+
+ --use-backslash
+ This option changes the interpretations of options which follow
+ this one. After the --use-backslash option, any backslash in an
+ option string is removed and the following character is taken
+ literally. This allows a dollar sign to be included in option
+ strings.
+
+ -- A command line argument of "--" marks the end of option argu-
+ ments. Any arguments following this are interpreted as file-
+ names. This can be useful when viewing a file whose name begins
+ with a "-" or "+".
+
+ + If a command line option begins with [1m+[22m, the remainder of that
+ option is taken to be an initial command to [4mless.[24m For example,
+ +G tells [4mless[24m to start at the end of the file rather than the
+ beginning, and +/xyz tells it to start at the first occurrence
+ of "xyz" in the file. As a special case, +<number> acts like
+ +<number>g; that is, it starts the display at the specified line
+ number (however, see the caveat under the "g" command above).
+ If the option starts with ++, the initial command applies to
+ every file being viewed, not just the first one. The + command
+ described previously may also be used to set (or change) an ini-
+ tial command for every file.
+
+
+[1mLINE EDITING[0m
+ When entering command line at the bottom of the screen (for example, a
+ filename for the :e command, or the pattern for a search command), cer-
+ tain keys can be used to manipulate the command line. Most commands
+ have an alternate form in [ brackets ] which can be used if a key does
+ not exist on a particular keyboard. (Note that the forms beginning
+ with ESC do not work in some MS-DOS and Windows systems because ESC is
+ the line erase character.) Any of these special keys may be entered
+ literally by preceding it with the "literal" character, either ^V or
+ ^A. A backslash itself may also be entered literally by entering two
+ backslashes.
+
+ LEFTARROW [ ESC-h ]
+ Move the cursor one space to the left.
+
+ RIGHTARROW [ ESC-l ]
+ Move the cursor one space to the right.
+
+ ^LEFTARROW [ ESC-b or ESC-LEFTARROW ]
+ (That is, CONTROL and LEFTARROW simultaneously.) Move the cur-
+ sor one word to the left.
+
+ ^RIGHTARROW [ ESC-w or ESC-RIGHTARROW ]
+ (That is, CONTROL and RIGHTARROW simultaneously.) Move the cur-
+ sor one word to the right.
+
+ HOME [ ESC-0 ]
+ Move the cursor to the beginning of the line.
+
+ END [ ESC-$ ]
+ Move the cursor to the end of the line.
+
+ BACKSPACE
+ Delete the character to the left of the cursor, or cancel the
+ command if the command line is empty.
+
+ DELETE or [ ESC-x ]
+ Delete the character under the cursor.
+
+ ^BACKSPACE [ ESC-BACKSPACE ]
+ (That is, CONTROL and BACKSPACE simultaneously.) Delete the
+ word to the left of the cursor.
+
+ ^DELETE [ ESC-X or ESC-DELETE ]
+ (That is, CONTROL and DELETE simultaneously.) Delete the word
+ under the cursor.
+
+ UPARROW [ ESC-k ]
+ Retrieve the previous command line. If you first enter some
+ text and then press UPARROW, it will retrieve the previous com-
+ mand which begins with that text.
+
+ DOWNARROW [ ESC-j ]
+ Retrieve the next command line. If you first enter some text
+ and then press DOWNARROW, it will retrieve the next command
+ which begins with that text.
+
+ TAB Complete the partial filename to the left of the cursor. If it
+ matches more than one filename, the first match is entered into
+ the command line. Repeated TABs will cycle thru the other
+ matching filenames. If the completed filename is a directory, a
+ "/" is appended to the filename. (On MS-DOS systems, a "\" is
+ appended.) The environment variable LESSSEPARATOR can be used
+ to specify a different character to append to a directory name.
+
+ BACKTAB [ ESC-TAB ]
+ Like, TAB, but cycles in the reverse direction thru the matching
+ filenames.
+
+ ^L Complete the partial filename to the left of the cursor. If it
+ matches more than one filename, all matches are entered into the
+ command line (if they fit).
+
+ ^U (Unix and OS/2) or ESC (MS-DOS)
+ Delete the entire command line, or cancel the command if the
+ command line is empty. If you have changed your line-kill char-
+ acter in Unix to something other than ^U, that character is used
+ instead of ^U.
+
+ ^G Delete the entire command line and return to the main prompt.
+
+
+[1mKEY BINDINGS[0m
+ You may define your own [4mless[24m commands by using the program [4mlesskey[24m (1)
+ to create a lesskey file. This file specifies a set of command keys
+ and an action associated with each key. You may also use [4mlesskey[24m to
+ change the line-editing keys (see LINE EDITING), and to set environment
+ variables. If the environment variable LESSKEY is set, [4mless[24m uses that
+ as the name of the lesskey file. Otherwise, [4mless[24m looks in a standard
+ place for the lesskey file: On Unix systems, [4mless[24m looks for a lesskey
+ file called "$HOME/.less". On MS-DOS and Windows systems, [4mless[24m looks
+ for a lesskey file called "$HOME/_less", and if it is not found there,
+ then looks for a lesskey file called "_less" in any directory specified
+ in the PATH environment variable. On OS/2 systems, [4mless[24m looks for a
+ lesskey file called "$HOME/less.ini", and if it is not found, then
+ looks for a lesskey file called "less.ini" in any directory specified
+ in the INIT environment variable, and if it not found there, then looks
+ for a lesskey file called "less.ini" in any directory specified in the
+ PATH environment variable. See the [4mlesskey[24m manual page for more
+ details.
+
+ A system-wide lesskey file may also be set up to provide key bindings.
+ If a key is defined in both a local lesskey file and in the system-wide
+ file, key bindings in the local file take precedence over those in the
+ system-wide file. If the environment variable LESSKEY_SYSTEM is set,
+ [4mless[24m uses that as the name of the system-wide lesskey file. Otherwise,
+ [4mless[24m looks in a standard place for the system-wide lesskey file: On
+ Unix systems, the system-wide lesskey file is /usr/local/etc/sysless.
+ (However, if [4mless[24m was built with a different sysconf directory than
+ /usr/local/etc, that directory is where the sysless file is found.) On
+ MS-DOS and Windows systems, the system-wide lesskey file is c:\_sys-
+ less. On OS/2 systems, the system-wide lesskey file is c:\sysless.ini.
+
+
+[1mINPUT PREPROCESSOR[0m
+ You may define an "input preprocessor" for [4mless.[24m Before [4mless[24m opens a
+ file, it first gives your input preprocessor a chance to modify the way
+ the contents of the file are displayed. An input preprocessor is sim-
+ ply an executable program (or shell script), which writes the contents
+ of the file to a different file, called the replacement file. The con-
+ tents of the replacement file are then displayed in place of the con-
+ tents of the original file. However, it will appear to the user as if
+ the original file is opened; that is, [4mless[24m will display the original
+ filename as the name of the current file.
+
+ An input preprocessor receives one command line argument, the original
+ filename, as entered by the user. It should create the replacement
+ file, and when finished, print the name of the replacement file to its
+ standard output. If the input preprocessor does not output a replace-
+ ment filename, [4mless[24m uses the original file, as normal. The input pre-
+ processor is not called when viewing standard input. To set up an
+ input preprocessor, set the LESSOPEN environment variable to a command
+ line which will invoke your input preprocessor. This command line
+ should include one occurrence of the string "%s", which will be
+ replaced by the filename when the input preprocessor command is
+ invoked.
+
+ When [4mless[24m closes a file opened in such a way, it will call another pro-
+ gram, called the input postprocessor, which may perform any desired
+ clean-up action (such as deleting the replacement file created by
+ LESSOPEN). This program receives two command line arguments, the orig-
+ inal filename as entered by the user, and the name of the replacement
+ file. To set up an input postprocessor, set the LESSCLOSE environment
+ variable to a command line which will invoke your input postprocessor.
+ It may include two occurrences of the string "%s"; the first is
+ replaced with the original name of the file and the second with the
+ name of the replacement file, which was output by LESSOPEN.
+
+ For example, on many Unix systems, these two scripts will allow you to
+ keep files in compressed format, but still let [4mless[24m view them directly:
+
+ lessopen.sh:
+ #! /bin/sh
+ case "$1" in
+ *.Z) uncompress -
+ if [ -s /tmp/less.$$ ]; then
+ echo /tmp/less.$$
+ else
+ rm -f /tmp/less.$$
+ fi
+ ;;
+ esac
+
+ lessclose.sh:
+ #! /bin/sh
+ rm $2
+
+ To use these scripts, put them both where they can be executed and set
+ LESSOPEN="lessopen.sh %s", and LESSCLOSE="lessclose.sh %s %s". More
+ complex LESSOPEN and LESSCLOSE scripts may be written to accept other
+ types of compressed files, and so on.
+
+ It is also possible to set up an input preprocessor to pipe the file
+ data directly to [4mless,[24m rather than putting the data into a replacement
+ file. This avoids the need to decompress the entire file before start-
+ ing to view it. An input preprocessor that works this way is called an
+ input pipe. An input pipe, instead of writing the name of a replace-
+ ment file on its standard output, writes the entire contents of the
+ replacement file on its standard output. If the input pipe does not
+ write any characters on its standard output, then there is no replace-
+ ment file and [4mless[24m uses the original file, as normal. To use an input
+ pipe, make the first character in the LESSOPEN environment variable a
+ vertical bar (|) to signify that the input preprocessor is an input
+ pipe.
+
+ For example, on many Unix systems, this script will work like the pre-
+ vious example scripts:
+
+ lesspipe.sh:
+ #! /bin/sh
+ case "$1" in
+ *.Z) uncompress -c $1 2>/dev/null
+ *) exit 1
+ ;;
+ esac
+ exit $?
+
+ To use this script, put it where it can be executed and set
+ LESSOPEN="|lesspipe.sh %s".
+
+ Note that a preprocessor cannot output an empty file, since that is
+ interpreted as meaning there is no replacement, and the original file
+ is used. To avoid this, if LESSOPEN starts with two vertical bars, the
+ exit status of the script becomes meaningful. If the exit status is
+ zero, the output is considered to be replacement text, even if it
+ empty. If the exit status is nonzero, any output is ignored and the
+ original file is used. For compatibility with previous versions of
+ [4mless,[24m if LESSOPEN starts with only one vertical bar, the exit status of
+ the preprocessor is ignored.
+
+ When an input pipe is used, a LESSCLOSE postprocessor can be used, but
+ it is usually not necessary since there is no replacement file to clean
+ up. In this case, the replacement file name passed to the LESSCLOSE
+ postprocessor is "-".
+
+ For compatibility with previous versions of [4mless,[24m the input preproces-
+ sor or pipe is not used if [4mless[24m is viewing standard input. However, if
+ the first character of LESSOPEN is a dash (-), the input preprocessor
+ is used on standard input as well as other files. In this case, the
+ dash is not considered to be part of the preprocessor command. If
+ standard input is being viewed, the input preprocessor is passed a file
+ name consisting of a single dash. Similarly, if the first two charac-
+ ters of LESSOPEN are vertical bar and dash (|-) or two vertical bars
+ and a dash (||-), the input pipe is used on standard input as well as
+ other files. Again, in this case the dash is not considered to be part
+ of the input pipe command.
+
+
+[1mNATIONAL CHARACTER SETS[0m
+ There are three types of characters in the input file:
+
+ normal characters
+ can be displayed directly to the screen.
+
+ control characters
+ should not be displayed directly, but are expected to be found
+ in ordinary text files (such as backspace and tab).
+
+ binary characters
+ should not be displayed directly and are not expected to be
+ found in text files.
+
+ A "character set" is simply a description of which characters are to be
+ considered normal, control, and binary. The LESSCHARSET environment
+ variable may be used to select a character set. Possible values for
+ LESSCHARSET are:
+
+ ascii BS, TAB, NL, CR, and formfeed are control characters, all chars
+ with values between 32 and 126 are normal, and all others are
+ binary.
+
+ iso8859
+ Selects an ISO 8859 character set. This is the same as ASCII,
+ except characters between 160 and 255 are treated as normal
+ characters.
+
+ latin1 Same as iso8859.
+
+ latin9 Same as iso8859.
+
+ dos Selects a character set appropriate for MS-DOS.
+
+ ebcdic Selects an EBCDIC character set.
+
+ IBM-1047
+ Selects an EBCDIC character set used by OS/390 Unix Services.
+ This is the EBCDIC analogue of latin1. You get similar results
+ by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US in your
+ environment.
+
+ koi8-r Selects a Russian character set.
+
+ next Selects a character set appropriate for NeXT computers.
+
+ utf-8 Selects the UTF-8 encoding of the ISO 10646 character set.
+ UTF-8 is special in that it supports multi-byte characters in
+ the input file. It is the only character set that supports
+ multi-byte characters.
+
+ windows
+ Selects a character set appropriate for Microsoft Windows (cp
+ 1251).
+
+ In rare cases, it may be desired to tailor [4mless[24m to use a character set
+ other than the ones definable by LESSCHARSET. In this case, the envi-
+ ronment variable LESSCHARDEF can be used to define a character set. It
+ should be set to a string where each character in the string represents
+ one character in the character set. The character "." is used for a
+ normal character, "c" for control, and "b" for binary. A decimal num-
+ ber may be used for repetition. For example, "bccc4b." would mean
+ character 0 is binary, 1, 2 and 3 are control, 4, 5, 6 and 7 are
+ binary, and 8 is normal. All characters after the last are taken to be
+ the same as the last, so characters 9 through 255 would be normal.
+ (This is an example, and does not necessarily represent any real char-
+ acter set.)
+
+ This table shows the value of LESSCHARDEF which is equivalent to each
+ of the possible values for LESSCHARSET:
+
+ ascii 8bcccbcc18b95.b
+ dos 8bcccbcc12bc5b95.b.
+ ebcdic 5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
+ 9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
+ IBM-1047 4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
+ 191.b
+ iso8859 8bcccbcc18b95.33b.
+ koi8-r 8bcccbcc18b95.b128.
+ latin1 8bcccbcc18b95.33b.
+ next 8bcccbcc18b95.bb125.bb
+
+ If neither LESSCHARSET nor LESSCHARDEF is set, but any of the strings
+ "UTF-8", "UTF8", "utf-8" or "utf8" is found in the LC_ALL, LC_CTYPE or
+ LANG environment variables, then the default character set is utf-8.
+
+ If that string is not found, but your system supports the [4msetlocale[0m
+ interface, [4mless[24m will use setlocale to determine the character set.
+ setlocale is controlled by setting the LANG or LC_CTYPE environment
+ variables.
+
+ Finally, if the [4msetlocale[24m interface is also not available, the default
+ character set is latin1.
+
+ Control and binary characters are displayed in standout (reverse
+ video). Each such character is displayed in caret notation if possible
+ (e.g. ^A for control-A). Caret notation is used only if inverting the
+ 0100 bit results in a normal printable character. Otherwise, the char-
+ acter is displayed as a hex number in angle brackets. This format can
+ be changed by setting the LESSBINFMT environment variable. LESSBINFMT
+ may begin with a "*" and one character to select the display attribute:
+ "*k" is blinking, "*d" is bold, "*u" is underlined, "*s" is standout,
+ and "*n" is normal. If LESSBINFMT does not begin with a "*", normal
+ attribute is assumed. The remainder of LESSBINFMT is a string which
+ may include one printf-style escape sequence (a % followed by x, X, o,
+ d, etc.). For example, if LESSBINFMT is "*u[%x]", binary characters
+ are displayed in underlined hexadecimal surrounded by brackets. The
+ default if no LESSBINFMT is specified is "*s<%02X>". Warning: the
+ result of expanding the character via LESSBINFMT must be less than 31
+ characters.
+
+ When the character set is utf-8, the LESSUTFBINFMT environment variable
+ acts similarly to LESSBINFMT but it applies to Unicode code points that
+ were successfully decoded but are unsuitable for display (e.g., unas-
+ signed code points). Its default value is "<U+%04lX>". Note that
+ LESSUTFBINFMT and LESSBINFMT share their display attribute setting
+ ("*x") so specifying one will affect both; LESSUTFBINFMT is read after
+ LESSBINFMT so its setting, if any, will have priority. Problematic
+ octets in a UTF-8 file (octets of a truncated sequence, octets of a
+ complete but non-shortest form sequence, illegal octets, and stray
+ trailing octets) are displayed individually using LESSBINFMT so as to
+ facilitate diagnostic of how the UTF-8 file is ill-formed.
+
+
+[1mPROMPTS[0m
+ The -P option allows you to tailor the prompt to your preference. The
+ string given to the -P option replaces the specified prompt string.
+ Certain characters in the string are interpreted specially. The prompt
+ mechanism is rather complicated to provide flexibility, but the ordi-
+ nary user need not understand the details of constructing personalized
+ prompt strings.
+
+ A percent sign followed by a single character is expanded according to
+ what the following character is:
+
+ %b[4mX[24m Replaced by the byte offset into the current input file. The b
+ is followed by a single character (shown as [4mX[24m above) which spec-
+ ifies the line whose byte offset is to be used. If the charac-
+ ter is a "t", the byte offset of the top line in the display is
+ used, an "m" means use the middle line, a "b" means use the bot-
+ tom line, a "B" means use the line just after the bottom line,
+ and a "j" means use the "target" line, as specified by the -j
+ option.
+
+ %B Replaced by the size of the current input file.
+
+ %c Replaced by the column number of the text appearing in the first
+ column of the screen.
+
+ %d[4mX[24m Replaced by the page number of a line in the input file. The
+ line to be used is determined by the [4mX[24m, as with the %b option.
+
+ %D Replaced by the number of pages in the input file, or equiva-
+ lently, the page number of the last line in the input file.
+
+ %E Replaced by the name of the editor (from the VISUAL environment
+ variable, or the EDITOR environment variable if VISUAL is not
+ defined). See the discussion of the LESSEDIT feature below.
+
+ %f Replaced by the name of the current input file.
+
+ %F Replaced by the last component of the name of the current input
+ file.
+
+ %i Replaced by the index of the current file in the list of input
+ files.
+
+ %l[4mX[24m Replaced by the line number of a line in the input file. The
+ line to be used is determined by the [4mX[24m, as with the %b option.
+
+ %L Replaced by the line number of the last line in the input file.
+
+ %m Replaced by the total number of input files.
+
+ %p[4mX[24m Replaced by the percent into the current input file, based on
+ byte offsets. The line used is determined by the [4mX[24m as with the
+ %b option.
+
+ %P[4mX[24m Replaced by the percent into the current input file, based on
+ line numbers. The line used is determined by the [4mX[24m as with the
+ %b option.
+
+ %s Same as %B.
+
+ %t Causes any trailing spaces to be removed. Usually used at the
+ end of the string, but may appear anywhere.
+
+ %x Replaced by the name of the next input file in the list.
+
+ If any item is unknown (for example, the file size if input is a pipe),
+ a question mark is printed instead.
+
+ The format of the prompt string can be changed depending on certain
+ conditions. A question mark followed by a single character acts like
+ an "IF": depending on the following character, a condition is evalu-
+ ated. If the condition is true, any characters following the question
+ mark and condition character, up to a period, are included in the
+ prompt. If the condition is false, such characters are not included.
+ A colon appearing between the question mark and the period can be used
+ to establish an "ELSE": any characters between the colon and the period
+ are included in the string if and only if the IF condition is false.
+ Condition characters (which follow a question mark) may be:
+
+ ?a True if any characters have been included in the prompt so far.
+
+ ?b[4mX[24m True if the byte offset of the specified line is known.
+
+ ?B True if the size of current input file is known.
+
+ ?c True if the text is horizontally shifted (%c is not zero).
+
+ ?d[4mX[24m True if the page number of the specified line is known.
+
+ ?e True if at end-of-file.
+
+ ?f True if there is an input filename (that is, if input is not a
+ pipe).
+
+ ?l[4mX[24m True if the line number of the specified line is known.
+
+ ?L True if the line number of the last line in the file is known.
+
+ ?m True if there is more than one input file.
+
+ ?n True if this is the first prompt in a new input file.
+
+ ?p[4mX[24m True if the percent into the current input file, based on byte
+ offsets, of the specified line is known.
+
+ ?P[4mX[24m True if the percent into the current input file, based on line
+ numbers, of the specified line is known.
+
+ ?s Same as "?B".
+
+ ?x True if there is a next input file (that is, if the current
+ input file is not the last one).
+
+ Any characters other than the special ones (question mark, colon,
+ period, percent, and backslash) become literally part of the prompt.
+ Any of the special characters may be included in the prompt literally
+ by preceding it with a backslash.
+
+ Some examples:
+
+ ?f%f:Standard input.
+
+ This prompt prints the filename, if known; otherwise the string "Stan-
+ dard input".
+
+ ?f%f .?ltLine %lt:?pt%pt\%:?btByte %bt:-...
+
+ This prompt would print the filename, if known. The filename is fol-
+ lowed by the line number, if known, otherwise the percent if known,
+ otherwise the byte offset if known. Otherwise, a dash is printed.
+ Notice how each question mark has a matching period, and how the %
+ after the %pt is included literally by escaping it with a backslash.
+
+ ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x..%t
+
+ This prints the filename if this is the first prompt in a file, fol-
+ lowed by the "file N of N" message if there is more than one input
+ file. Then, if we are at end-of-file, the string "(END)" is printed
+ followed by the name of the next file, if there is one. Finally, any
+ trailing spaces are truncated. This is the default prompt. For refer-
+ ence, here are the defaults for the other two prompts (-m and -M
+ respectively). Each is broken into two lines here for readability
+ only.
+
+ ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x.:
+ ?pB%pB\%:byte %bB?s/%s...%t
+
+ ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. :
+ byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t
+
+ And here is the default message produced by the = command:
+
+ ?f%f .?m(file %i of %m) .?ltlines %lt-%lb?L/%L. .
+ byte %bB?s/%s. ?e(END) :?pB%pB\%..%t
+
+ The prompt expansion features are also used for another purpose: if an
+ environment variable LESSEDIT is defined, it is used as the command to
+ be executed when the v command is invoked. The LESSEDIT string is
+ expanded in the same way as the prompt strings. The default value for
+ LESSEDIT is:
+
+ %E ?lm+%lm. %f
+
+ Note that this expands to the editor name, followed by a + and the line
+ number, followed by the file name. If your editor does not accept the
+ "+linenumber" syntax, or has other differences in invocation syntax,
+ the LESSEDIT variable can be changed to modify this default.
+
+
+[1mSECURITY[0m
+ When the environment variable LESSSECURE is set to 1, [4mless[24m runs in a
+ "secure" mode. This means these features are disabled:
+
+ ! the shell command
+
+ | the pipe command
+
+ :e the examine command.
+
+ v the editing command
+
+ s -o log files
+
+ -k use of lesskey files
+
+ -t use of tags files
+
+ metacharacters in filenames, such as *
+
+ filename completion (TAB, ^L)
+
+ Less can also be compiled to be permanently in "secure" mode.
+
+
+[1mCOMPATIBILITY WITH MORE[0m
+ If the environment variable LESS_IS_MORE is set to 1, or if the program
+ is invoked via a file link named "more", [4mless[24m behaves (mostly) in con-
+ formance with the POSIX "more" command specification. In this mode,
+ less behaves differently in these ways:
+
+ The -e option works differently. If the -e option is not set, [4mless[0m
+ behaves as if the -E option were set. If the -e option is set, [4mless[0m
+ behaves as if the -e and -F options were set.
+
+ The -m option works differently. If the -m option is not set, the
+ medium prompt is used, and it is prefixed with the string "--More--".
+ If the -m option is set, the short prompt is used.
+
+ The -n option acts like the -z option. The normal behavior of the -n
+ option is unavailable in this mode.
+
+ The parameter to the -p option is taken to be a [4mless[24m command rather
+ than a search pattern.
+
+ The LESS environment variable is ignored, and the MORE environment
+ variable is used in its place.
+
+
+[1mENVIRONMENT VARIABLES[0m
+ Environment variables may be specified either in the system environment
+ as usual, or in a [4mlesskey[24m (1) file. If environment variables are
+ defined in more than one place, variables defined in a local lesskey
+ file take precedence over variables defined in the system environment,
+ which take precedence over variables defined in the system-wide lesskey
+ file.
+
+ COLUMNS
+ Sets the number of columns on the screen. Takes precedence over
+ the number of columns specified by the TERM variable. (But if
+ you have a windowing system which supports TIOCGWINSZ or
+ WIOCGETD, the window system's idea of the screen size takes
+ precedence over the LINES and COLUMNS environment variables.)
+
+ EDITOR The name of the editor (used for the v command).
+
+ HOME Name of the user's home directory (used to find a lesskey file
+ on Unix and OS/2 systems).
+
+ HOMEDRIVE, HOMEPATH
+ Concatenation of the HOMEDRIVE and HOMEPATH environment vari-
+ ables is the name of the user's home directory if the HOME vari-
+ able is not set (only in the Windows version).
+
+ INIT Name of the user's init directory (used to find a lesskey file
+ on OS/2 systems).
+
+ LANG Language for determining the character set.
+
+ LC_CTYPE
+ Language for determining the character set.
+
+ LESS Options which are passed to [4mless[24m automatically.
+
+ LESSANSIENDCHARS
+ Characters which may end an ANSI color escape sequence (default
+ "m").
+
+ LESSANSIMIDCHARS
+ Characters which may appear between the ESC character and the
+ end character in an ANSI color escape sequence (default
+ "0123456789;[?!"'#%()*+ ".
+
+ LESSBINFMT
+ Format for displaying non-printable, non-control characters.
+
+ LESSCHARDEF
+ Defines a character set.
+
+ LESSCHARSET
+ Selects a predefined character set.
+
+ LESSCLOSE
+ Command line to invoke the (optional) input-postprocessor.
+
+ LESSECHO
+ Name of the lessecho program (default "lessecho"). The lessecho
+ program is needed to expand metacharacters, such as * and ?, in
+ filenames on Unix systems.
+
+ LESSEDIT
+ Editor prototype string (used for the v command). See discus-
+ sion under PROMPTS.
+
+ LESSGLOBALTAGS
+ Name of the command used by the -t option to find global tags.
+ Normally should be set to "global" if your system has the [4mglobal[0m
+ (1) command. If not set, global tags are not used.
+
+ LESSHISTFILE
+ Name of the history file used to remember search commands and
+ shell commands between invocations of [4mless.[24m If set to "-" or
+ "/dev/null", a history file is not used. The default is
+ "$HOME/.lesshst" on Unix systems, "$HOME/_lesshst" on DOS and
+ Windows systems, or "$HOME/lesshst.ini" or "$INIT/lesshst.ini"
+ on OS/2 systems.
+
+ LESSHISTSIZE
+ The maximum number of commands to save in the history file. The
+ default is 100.
+
+ LESSKEY
+ Name of the default lesskey(1) file.
+
+ LESSKEY_SYSTEM
+ Name of the default system-wide lesskey(1) file.
+
+ LESSMETACHARS
+ List of characters which are considered "metacharacters" by the
+ shell.
+
+ LESSMETAESCAPE
+ Prefix which less will add before each metacharacter in a com-
+ mand sent to the shell. If LESSMETAESCAPE is an empty string,
+ commands containing metacharacters will not be passed to the
+ shell.
+
+ LESSOPEN
+ Command line to invoke the (optional) input-preprocessor.
+
+ LESSSECURE
+ Runs less in "secure" mode. See discussion under SECURITY.
+
+ LESSSEPARATOR

+ tion.
+
+ LESSUTFBINFMT
+ Format for displaying non-printable Unicode code points.
+
+ LESS_IS_MORE
+ Emulate the [4mmore[24m (1) command.
+
+ LINES Sets the number of lines on the screen. Takes precedence over
+ the number of lines specified by the TERM variable. (But if you
+ have a windowing system which supports TIOCGWINSZ or WIOCGETD,
+ the window system's idea of the screen size takes precedence
+ over the LINES and COLUMNS environment variables.)
+
+ MORE Options which are passed to [4mless[24m automatically when running in
+ [4mmore[24m compatible mode.
+
+ PATH User's search path (used to find a lesskey file on MS-DOS and
+ OS/2 systems).
+
+ SHELL The shell used to execute the ! command, as well as to expand

-
-.SH DESCRIPTION
-.I Less
-is a program similar to
-.I more
-(1), but which allows backward movement
-in the file as well as forward movement.
-Also,
-.I less
-does not have to read the entire input file before starting,
-so with large input files it starts up faster than text editors like
-.I vi
-(1).
-.I Less
-uses termcap (or terminfo on some systems),
-so it can run on a variety of terminals.
-There is even limited support for hardcopy terminals.
-(On a hardcopy terminal, lines which should be printed at the top
-of the screen are prefixed with a caret.)
-.PP
-Commands are based on both
-.I more
-and
-.I vi.
-Commands may be preceded by a decimal number,
-called N in the descriptions below.
-The number is used by some commands, as indicated.
-
-.SH COMMANDS
-In the following descriptions, ^X means control-X.
-ESC stands for the ESCAPE key; for example ESC-v means the
-two character sequence "ESCAPE", then "v".
-.IP "h or H"
-Help: display a summary of these commands.
-If you forget all the other commands, remember this one.
-.IP "SPACE or ^V or f or ^F"
-Scroll forward N lines, default one window (see option \-z below).
-If N is more than the screen size, only the final screenful is displayed.
-Warning: some systems use ^V as a special literalization character.
-.IP "z"
-Like SPACE, but if N is specified, it becomes the new window size.
-.IP "ESC-SPACE"
-Like SPACE, but scrolls a full screenful, even if it reaches
-end-of-file in the process.
-.IP "RETURN or ^N or e or ^E or j or ^J"
-Scroll forward N lines, default 1.
-The entire N lines are displayed, even if N is more than the screen size.
-.IP "d or ^D"
-Scroll forward N lines, default one half of the screen size.
-If N is specified, it becomes the new default for
-subsequent d and u commands.
-.IP "b or ^B or ESC-v"
-Scroll backward N lines, default one window (see option \-z below).
-If N is more than the screen size, only the final screenful is displayed.
-.IP "w"
-Like ESC-v, but if N is specified, it becomes the new window size.
-.IP "y or ^Y or ^P or k or ^K"
-Scroll backward N lines, default 1.
-The entire N lines are displayed, even if N is more than the screen size.
-Warning: some systems use ^Y as a special job control character.
-.IP "u or ^U"
-Scroll backward N lines, default one half of the screen size.
-If N is specified, it becomes the new default for
-subsequent d and u commands.
-.IP "ESC-) or RIGHTARROW"
-Scroll horizontally right N characters, default half the screen width
-(see the \-# option).
-If a number N is specified, it becomes the default for future RIGHTARROW
-and LEFTARROW commands.
-While the text is scrolled, it acts as though the \-S option
-(chop lines) were in effect.
-.IP "ESC-( or LEFTARROW"
-Scroll horizontally left N characters, default half the screen width
-(see the \-# option).
-If a number N is specified, it becomes the default for future RIGHTARROW
-and LEFTARROW commands.
-.IP "r or ^R or ^L"
-Repaint the screen.
-.IP R
-Repaint the screen, discarding any buffered input.
-Useful if the file is changing while it is being viewed.
-.IP "F"
-Scroll forward, and keep trying to read when the
-end of file is reached.
-Normally this command would be used when already at the end of the file.
-It is a way to monitor the tail of a file which is growing
-while it is being viewed.
-(The behavior is similar to the "tail \-f" command.)
-.IP "g or < or ESC-<"
-Go to line N in the file, default 1 (beginning of file).
-(Warning: this may be slow if N is large.)
-.IP "G or > or ESC->"
-Go to line N in the file, default the end of the file.
-(Warning: this may be slow if N is large,
-or if N is not specified and
-standard input, rather than a file, is being read.)
-.IP "p or %"
-Go to a position N percent into the file.
-N should be between 0 and 100, and may contain a decimal point.
-.IP "P"
-Go to the line containing byte offset N in the file.
-.IP "{"
-If a left curly bracket appears in the top line displayed
-on the screen,
-the { command will go to the matching right curly bracket.
-The matching right curly bracket is positioned on the bottom
-line of the screen.
-If there is more than one left curly bracket on the top line,
-a number N may be used to specify the N-th bracket on the line.
-.IP "}"
-If a right curly bracket appears in the bottom line displayed
-on the screen,
-the } command will go to the matching left curly bracket.
-The matching left curly bracket is positioned on the top
-line of the screen.
-If there is more than one right curly bracket on the top line,
-a number N may be used to specify the N-th bracket on the line.
-.IP "("
-Like {, but applies to parentheses rather than curly brackets.
-.IP ")"
-Like }, but applies to parentheses rather than curly brackets.
-.IP "["
-Like {, but applies to square brackets rather than curly brackets.
-.IP "]"
-Like }, but applies to square brackets rather than curly brackets.
-.IP "ESC-^F"
-Followed by two characters,
-acts like {, but uses the two characters as open and close brackets,
-respectively.
-For example, "ESC ^F < >" could be used to
-go forward to the > which matches the < in the top displayed line.
-.IP "ESC-^B"
-Followed by two characters,
-acts like }, but uses the two characters as open and close brackets,
-respectively.
-For example, "ESC ^B < >" could be used to
-go backward to the < which matches the > in the bottom displayed line.
-.IP m
-Followed by any lowercase letter,
-marks the current position with that letter.
-.IP "'"
-(Single quote.)
-Followed by any lowercase letter, returns to the position which
-was previously marked with that letter.
-Followed by another single quote, returns to the position at
-which the last "large" movement command was executed.
-Followed by a ^ or $, jumps to the beginning or end of the
-file respectively.
-Marks are preserved when a new file is examined,
-so the ' command can be used to switch between input files.
-.IP "^X^X"
-Same as single quote.
-.IP /pattern
-Search forward in the file for the N-th line containing the pattern.
-N defaults to 1.
-The pattern is a regular expression, as recognized by
-the regular expression library supplied by your system.
-The search starts at the second line displayed
-(but see the \-a and \-j options, which change this).
-.sp
-Certain characters are special
-if entered at the beginning of the pattern;
-they modify the type of search rather than become part of the pattern:
-.RS
-.IP "^N or !"
-Search for lines which do NOT match the pattern.
-.IP "^E or *"
-Search multiple files.
-That is, if the search reaches the END of the current file
-without finding a match,
-the search continues in the next file in the command line list.
-.IP "^F or @"
-Begin the search at the first line of the FIRST file
-in the command line list,
-regardless of what is currently displayed on the screen
-or the settings of the \-a or \-j options.
-.IP "^K"
-Highlight any text which matches the pattern on the current screen,
-but don't move to the first match (KEEP current position).
-.IP "^R"
-Don't interpret regular expression metacharacters;
-that is, do a simple textual comparison.
-.RE
-.IP ?pattern
-Search backward in the file for the N-th line containing the pattern.
-The search starts at the line immediately before the top line displayed.
-.sp
-Certain characters are special as in the / command:
-.RS
-.IP "^N or !"
-Search for lines which do NOT match the pattern.
-.IP "^E or *"
-Search multiple files.
-That is, if the search reaches the beginning of the current file
-without finding a match,
-the search continues in the previous file in the command line list.
-.IP "^F or @"
-Begin the search at the last line of the last file
-in the command line list,
-regardless of what is currently displayed on the screen
-or the settings of the \-a or \-j options.
-.IP "^K"
-As in forward searches.
-.IP "^R"
-As in forward searches.
-.RE
-.IP "ESC-/pattern"
-Same as "/*".
-.IP "ESC-?pattern"
-Same as "?*".
-.IP n
-Repeat previous search, for N-th line containing the last pattern.
-If the previous search was modified by ^N, the search is made for the
-N-th line NOT containing the pattern.
-If the previous search was modified by ^E, the search continues
-in the next (or previous) file if not satisfied in the current file.
-If the previous search was modified by ^R, the search is done
-without using regular expressions.
-There is no effect if the previous search was modified by ^F or ^K.
-.IP N
-Repeat previous search, but in the reverse direction.
-.IP "ESC-n"
-Repeat previous search, but crossing file boundaries.
-The effect is as if the previous search were modified by *.
-.IP "ESC-N"
-Repeat previous search, but in the reverse direction
-and crossing file boundaries.
-.IP "ESC-u"
-Undo search highlighting.
-Turn off highlighting of strings matching the current search pattern.
-If highlighting is already off because of a previous ESC-u command,
-turn highlighting back on.
-Any search command will also turn highlighting back on.
-(Highlighting can also be disabled by toggling the \-G option;
-in that case search commands do not turn highlighting back on.)
-.IP "&pattern"
-Display only lines which match the pattern;
-lines which do not match the pattern are not displayed.
-If pattern is empty (if you type & immediately followed by ENTER),
-any filtering is turned off, and all lines are displayed.
-While filtering is in effect, an ampersand is displayed at the
-beginning of the prompt,
-as a reminder that some lines in the file may be hidden.
-.sp
-Certain characters are special as in the / command:
-.RS
-.IP "^N or !"
-Display only lines which do NOT match the pattern.
-.IP "^R"
-Don't interpret regular expression metacharacters;
-that is, do a simple textual comparison.
-.RE
-.IP ":e [filename]"
-Examine a new file.
-If the filename is missing, the "current" file (see the :n and :p commands
-below) from the list of files in the command line is re-examined.
-A percent sign (%) in the filename is replaced by the name of the
-current file.
-A pound sign (#) is replaced by the name of the previously examined file.
-However, two consecutive percent signs are simply
-replaced with a single percent sign.
-This allows you to enter a filename that contains a percent sign
-in the name.
-Similarly, two consecutive pound signs are replaced with a single pound sign.
-The filename is inserted into the command line list of files
-so that it can be seen by subsequent :n and :p commands.
-If the filename consists of several files, they are all inserted into
-the list of files and the first one is examined.
-If the filename contains one or more spaces,
-the entire filename should be enclosed in double quotes
-(also see the \-" option).
-.IP "^X^V or E"
-Same as :e.
-Warning: some systems use ^V as a special literalization character.
-On such systems, you may not be able to use ^V.
-.IP ":n"
-Examine the next file (from the list of files given in the command line).
-If a number N is specified, the N-th next file is examined.
-.IP ":p"
-Examine the previous file in the command line list.
-If a number N is specified, the N-th previous file is examined.
-.IP ":x"
-Examine the first file in the command line list.
-If a number N is specified, the N-th file in the list is examined.
-.IP ":d"
-Remove the current file from the list of files.
-.IP "t"
-Go to the next tag, if there were more than one matches for the current tag.
-See the \-t option for more details about tags.
-.IP "T"
-Go to the previous tag, if there were more than one matches for the current tag.
-.IP "= or ^G or :f"
-Prints some information about the file being viewed,
-including its name
-and the line number and byte offset of the bottom line being displayed.
-If possible, it also prints the length of the file,
-the number of lines in the file
-and the percent of the file above the last displayed line.
-.IP \-
-Followed by one of the command line option letters (see OPTIONS below),
-this will change the setting of that option
-and print a message describing the new setting.
-If a ^P (CONTROL-P) is entered immediately after the dash,
-the setting of the option is changed but no message is printed.
-If the option letter has a numeric value (such as \-b or \-h),
-or a string value (such as \-P or \-t),
-a new value may be entered after the option letter.
-If no new value is entered, a message describing
-the current setting is printed and nothing is changed.
-.IP \-\-
-Like the \- command, but takes a long option name (see OPTIONS below)
-rather than a single option letter.
-You must press RETURN after typing the option name.
-A ^P immediately after the second dash suppresses printing of a
-message describing the new setting, as in the \- command.
-.IP \-+
-Followed by one of the command line option letters
-this will reset the option to its default setting
-and print a message describing the new setting.
-(The "\-+\fIX\fP" command does the same thing
-as "\-+\fIX\fP" on the command line.)
-This does not work for string-valued options.
-.IP \-\-+
-Like the \-+ command, but takes a long option name
-rather than a single option letter.
-.IP \-!
-Followed by one of the command line option letters,
-this will reset the option to the "opposite" of its default setting
-and print a message describing the new setting.
-This does not work for numeric or string-valued options.
-.IP \-\-!
-Like the \-! command, but takes a long option name
-rather than a single option letter.
-.IP _
-(Underscore.)
-Followed by one of the command line option letters,
-this will print a message describing the current setting of that option.
-The setting of the option is not changed.
-.IP __
-(Double underscore.)
-Like the _ (underscore) command, but takes a long option name
-rather than a single option letter.
-You must press RETURN after typing the option name.
-.IP +cmd
-Causes the specified cmd to be executed each time a new file is examined.
-For example, +G causes
-.I less
-to initially display each file starting at the end
-rather than the beginning.
-.IP V
-Prints the version number of
-.I less
-being run.
-.IP "q or Q or :q or :Q or ZZ"
-Exits
-.I less.
-.PP
-The following
-four
-commands may or may not be valid, depending on your particular installation.
-.PP
-.IP v
-Invokes an editor to edit the current file being viewed.
-The editor is taken from the environment variable VISUAL if defined,
-or EDITOR if VISUAL is not defined,
-or defaults to "vi" if neither VISUAL nor EDITOR is defined.
-See also the discussion of LESSEDIT under the section on PROMPTS below.
-.IP "! shell-command"
-Invokes a shell to run the shell-command given.
-A percent sign (%) in the command is replaced by the name of the
-current file.
-A pound sign (#) is replaced by the name of the previously examined file.
-"!!" repeats the last shell command.
-"!" with no shell command simply invokes a shell.
-On Unix systems, the shell is taken from the environment variable SHELL,
-or defaults to "sh".
-On MS-DOS and OS/2 systems, the shell is the normal command processor.
-.IP "| <m> shell-command"
-<m> represents any mark letter.
-Pipes a section of the input file to the given shell command.
-The section of the file to be piped is between the first line on
-the current screen and the position marked by the letter.
-<m> may also be ^ or $ to indicate beginning or end of file respectively.
-If <m> is . or newline, the current screen is piped.
-.IP "s filename"
-Save the input to a file.
-This only works if the input is a pipe, not an ordinary file.
-.PP
-.SH OPTIONS
-Command line options are described below.
-Most options may be changed while
-.I less
-is running, via the "\-" command.
-.PP
-Most options may be given in one of two forms:
-either a dash followed by a single letter,
-or two dashes followed by a long option name.
-A long option name may be abbreviated as long as
-the abbreviation is unambiguous.
-For example, \-\-quit-at-eof may be abbreviated \-\-quit, but not
---qui, since both \-\-quit-at-eof and \-\-quiet begin with \-\-qui.
-Some long option names are in uppercase, such as \-\-QUIT-AT-EOF, as
-distinct from \-\-quit-at-eof.
-Such option names need only have their first letter capitalized;
-the remainder of the name may be in either case.
-For example, \-\-Quit-at-eof is equivalent to \-\-QUIT-AT-EOF.
-.PP
-Options are also taken from the environment variable "LESS".
-For example,
-to avoid typing "less \-options ..." each time
-.I less
-is invoked, you might tell
-.I csh:
-.sp
-setenv LESS "-options"
-.sp
-or if you use
-.I sh:
-.sp
-LESS="-options"; export LESS
-.sp
-On MS-DOS, you don't need the quotes, but you should replace any
-percent signs in the options string by double percent signs.
-.sp
-The environment variable is parsed before the command line,
-so command line options override the LESS environment variable.
-If an option appears in the LESS variable, it can be reset
-to its default value on the command line by beginning the command
-line option with "\-+".
-.sp
-For options like \-P or \-D which take a following string,
-a dollar sign ($) must be used to signal the end of the string.
-For example, to set two \-D options on MS-DOS, you must have
-a dollar sign between them, like this:
-.sp
-LESS="-Dn9.1$-Ds4.1"
-.sp
-.IP "\-? or \-\-help"
-This option displays a summary of the commands accepted by
-.I less
-(the same as the h command).
-(Depending on how your shell interprets the question mark,
-it may be necessary to quote the question mark, thus: "\-\e?".)
-.IP "\-a or \-\-search-skip-screen"
-Causes searches to start after the last line
-displayed on the screen,
-thus skipping all lines displayed on the screen.
-By default, searches start at the second line on the screen
-(or after the last found line; see the \-j option).
-.IP "\-b\fIn\fP or \-\-buffers=\fIn\fP"
-Specifies the amount of buffer space
-.I less
-will use for each file, in units of kilobytes (1024 bytes).
-By default 64K of buffer space is used for each file
-(unless the file is a pipe; see the \-B option).
-The \-b option specifies instead that \fIn\fP kilobytes of
-buffer space should be used for each file.
-If \fIn\fP is \-1, buffer space is unlimited; that is,
-the entire file can be read into memory.
-.IP "\-B or \-\-auto-buffers"
-By default, when data is read from a pipe,
-buffers are allocated automatically as needed.
-If a large amount of data is read from the pipe, this can cause
-a large amount of memory to be allocated.
-The \-B option disables this automatic allocation of buffers for pipes,
-so that only 64K
-(or the amount of space specified by the \-b option)
-is used for the pipe.
-Warning: use of \-B can result in erroneous display, since only the
-most recently viewed part of the piped data is kept in memory;
-any earlier data is lost.
-.IP "\-c or \-\-clear-screen"
-Causes full screen repaints to be painted from the top line down.
-By default,
-full screen repaints are done by scrolling from the bottom of the screen.
-.IP "\-C or \-\-CLEAR-SCREEN"
-Same as \-c, for compatibility with older versions of
-.I less.
-.IP "\-d or \-\-dumb"
-The \-d option suppresses the error message
-normally displayed if the terminal is dumb;
-that is, lacks some important capability,
-such as the ability to clear the screen or scroll backward.
-The \-d option does not otherwise change the behavior of
-.I less
-on a dumb terminal.
-.IP "\-D\fBx\fP\fIcolor\fP or \-\-color=\fBx\fP\fIcolor\fP"
-[MS-DOS only]
-Sets the color of the text displayed.
-\fBx\fP is a single character which selects the type of text whose color is
-being set: n=normal, s=standout, d=bold, u=underlined, k=blink.
-\fIcolor\fP is a pair of numbers separated by a period.
-The first number selects the foreground color and the second selects
-the background color of the text.
-A single number \fIN\fP is the same as \fIN.M\fP,
-where \fIM\fP is the normal background color.
-
-.IP "\-e or \-\-quit-at-eof"
-Causes
-.I less
-to automatically exit
-the second time it reaches end-of-file.
-By default, the only way to exit
-.I less
-is via the "q" command.
-.IP "\-E or \-\-QUIT-AT-EOF"
-Causes
-.I less
-to automatically exit the first time it reaches end-of-file.
-.IP "\-f or \-\-force"
-Forces non-regular files to be opened.
-(A non-regular file is a directory or a device special file.)
-Also suppresses the warning message when a binary file is opened.
-By default,
-.I less
-will refuse to open non-regular files.
-Note that some operating systems will not allow directories
-to be read, even if \-f is set.
-.IP "\-F or \-\-quit-if-one-screen"
-Causes
-.I less
-to automatically exit
-if the entire file can be displayed on the first screen.
-.IP "\-g or \-\-hilite-search"
-Normally,
-.I less
-will highlight ALL strings which match the last search command.
-The \-g option changes this behavior to highlight only the particular string
-which was found by the last search command.
-This can cause
-.I less
-to run somewhat faster than the default.
-.IP "\-G or \-\-HILITE-SEARCH"
-The \-G option suppresses all highlighting of strings found by search commands.
-.IP "\-h\fIn\fP or \-\-max-back-scroll=\fIn\fP"
-Specifies a maximum number of lines to scroll backward.
-If it is necessary to scroll backward more than \fIn\fP lines,
-the screen is repainted in a forward direction instead.
-(If the terminal does not have the ability to scroll
-backward, \-h0 is implied.)
-.IP "\-i or \-\-ignore-case"
-Causes searches to ignore case; that is,
-uppercase and lowercase are considered identical.
-This option is ignored if any uppercase letters
-appear in the search pattern;
-in other words,
-if a pattern contains uppercase letters, then that search does not ignore case.
-.IP "\-I or \-\-IGNORE-CASE"
-Like \-i, but searches ignore case even if
-the pattern contains uppercase letters.
-.IP "\-j\fIn\fP or \-\-jump-target=\fIn\fP"
-Specifies a line on the screen where the "target" line
-is to be positioned.
-The target line is the line specified by any command to
-search for a pattern, jump to a line number,
-jump to a file percentage or jump to a tag.
-The screen line may be specified by a number: the top line on the screen
-is 1, the next is 2, and so on.
-The number may be negative to specify a line relative to the bottom
-of the screen: the bottom line on the screen is \-1, the second
-to the bottom is \-2, and so on.
-Alternately, the screen line may be specified as a fraction of the height
-of the screen, starting with a decimal point: .5 is in the middle of the
-screen, .3 is three tenths down from the first line, and so on.
-If the line is specified as a fraction, the actual line number
-is recalculated if the terminal window is resized, so that the
-target line remains at the specified fraction of the screen height.
-If any form of the \-j option is used,
-forward searches begin at the line immediately after the target line,
-and backward searches begin at the target line.
-For example, if "\-j4" is used, the target line is the
-fourth line on the screen, so forward searches begin at the fifth line
-on the screen.
-.IP "\-J or \-\-status-column"
-Displays a status column at the left edge of the screen.
-The status column shows the lines that matched the current search.
-The status column is also used if the \-w or \-W option is in effect.
-.IP "\-k\fIfilename\fP or \-\-lesskey-file=\fIfilename\fP"
-Causes
-.I less
-to open and interpret the named file as a
-.I lesskey
-(1) file.
-Multiple \-k options may be specified.
-If the LESSKEY or LESSKEY_SYSTEM environment variable is set, or
-if a lesskey file is found in a standard place (see KEY BINDINGS),
-it is also used as a
-.I lesskey
-file.
-.IP "\-K or \-\-quit-on-intr"
-Causes
-.I less
-to exit immediately when an interrupt character (usually ^C) is typed.
-Normally, an interrupt character causes
-.I less
-to stop whatever it is doing and return to its command prompt.
-Note that use of this option makes it impossible to return to the
-command prompt from the "F" command.
-.IP "\-L or \-\-no-lessopen"
-Ignore the LESSOPEN environment variable
-(see the INPUT PREPROCESSOR section below).
-This option can be set from within \fIless\fP,
-but it will apply only to files opened subsequently, not to the
-file which is currently open.
-.IP "\-m or \-\-long-prompt"
-Causes
-.I less
-to prompt verbosely (like \fImore\fP),
-with the percent into the file.
-By default,
-.I less
-prompts with a colon.
-.IP "\-M or \-\-LONG-PROMPT"
-Causes
-.I less
-to prompt even more verbosely than
-.I more.
-.IP "\-n or \-\-line-numbers"
-Suppresses line numbers.
-The default (to use line numbers) may cause
-.I less
-to run more slowly in some cases, especially with a very large input file.
-Suppressing line numbers with the \-n option will avoid this problem.
-Using line numbers means: the line number will be displayed in the verbose
-prompt and in the = command,
-and the v command will pass the current line number to the editor
-(see also the discussion of LESSEDIT in PROMPTS below).
-.IP "\-N or \-\-LINE-NUMBERS"
-Causes a line number to be displayed at the beginning of
-each line in the display.
-.IP "\-o\fIfilename\fP or \-\-log-file=\fIfilename\fP"
-Causes
-.I less
-to copy its input to the named file as it is being viewed.
-This applies only when the input file is a pipe,
-not an ordinary file.
-If the file already exists,
-.I less
-will ask for confirmation before overwriting it.
-.IP "\-O\fIfilename\fP or \-\-LOG-FILE=\fIfilename\fP"
-The \-O option is like \-o, but it will overwrite an existing
-file without asking for confirmation.
-.sp
-If no log file has been specified,
-the \-o and \-O options can be used from within
-.I less
-to specify a log file.
-Without a file name, they will simply report the name of the log file.
-The "s" command is equivalent to specifying \-o from within
-.I less.
-.IP "\-p\fIpattern\fP or \-\-pattern=\fIpattern\fP"
-The \-p option on the command line is equivalent to
-specifying +/\fIpattern\fP;
-that is, it tells
-.I less
-to start at the first occurrence of \fIpattern\fP in the file.
-.IP "\-P\fIprompt\fP or \-\-prompt=\fIprompt\fP"
-Provides a way to tailor the three prompt
-styles to your own preference.
-This option would normally be put in the LESS environment
-variable, rather than being typed in with each
-.I less
-command.
-Such an option must either be the last option in the LESS variable,
-or be terminated by a dollar sign.
--Ps followed by a string changes the default (short) prompt
-to that string.
--Pm changes the medium (\-m) prompt.
--PM changes the long (\-M) prompt.
--Ph changes the prompt for the help screen.
--P= changes the message printed by the = command.
--Pw changes the message printed while waiting for data (in the F command).
-All prompt strings consist of a sequence of
-letters and special escape sequences.
-See the section on PROMPTS for more details.
-.IP "\-q or \-\-quiet or \-\-silent"
-Causes moderately "quiet" operation:
-the terminal bell is not rung
-if an attempt is made to scroll past the end of the file
-or before the beginning of the file.
-If the terminal has a "visual bell", it is used instead.
-The bell will be rung on certain other errors,
-such as typing an invalid character.
-The default is to ring the terminal bell in all such cases.
-.IP "\-Q or \-\-QUIET or \-\-SILENT"
-Causes totally "quiet" operation:
-the terminal bell is never rung.
-.IP "\-r or \-\-raw-control-chars"
-Causes "raw" control characters to be displayed.
-The default is to display control characters using the caret notation;
-for example, a control-A (octal 001) is displayed as "^A".
-Warning: when the \-r option is used,
-.I less
-cannot keep track of the actual appearance of the screen
-(since this depends on how the screen responds to
-each type of control character).
-Thus, various display problems may result,
-such as long lines being split in the wrong place.
-.IP "\-R or \-\-RAW-CONTROL-CHARS"
-Like \-r, but only ANSI "color" escape sequences are output in "raw" form.
-Unlike \-r, the screen appearance is maintained correctly in most cases.
-ANSI "color" escape sequences are sequences of the form:
-.sp
- ESC [ ... m
-.sp
-where the "..." is zero or more color specification characters
-For the purpose of keeping track of screen appearance,
-ANSI color escape sequences are assumed to not move the cursor.
-You can make
-.I less
-think that characters other than "m" can end ANSI color escape sequences
-by setting the environment variable LESSANSIENDCHARS to the list of
-characters which can end a color escape sequence.
-And you can make
-.I less
-think that characters other than the standard ones may appear between
-the ESC and the m by setting the environment variable LESSANSIMIDCHARS
-to the list of characters which can appear.
-.IP "\-s or \-\-squeeze-blank-lines"
-Causes consecutive blank lines to be squeezed into a single blank line.
-This is useful when viewing
-.I nroff
-output.
-.IP "\-S or \-\-chop-long-lines"
-Causes lines longer than the screen width to be
-chopped rather than folded.
-That is, the portion of a long line that does not fit in
-the screen width is not shown.
-The default is to fold long lines; that is, display the remainder
-on the next line.
-.IP "\-t\fItag\fP or \-\-tag=\fItag\fP"
-The \-t option, followed immediately by a TAG,
-will edit the file containing that tag.
-For this to work, tag information must be available;
-for example, there may be a file in the current directory called "tags",
-which was previously built by
-.I ctags
-(1) or an equivalent command.
-If the environment variable LESSGLOBALTAGS is set, it is taken to be
-the name of a command compatible with
-.I global
-(1), and that command is executed to find the tag.
-(See http://www.gnu.org/software/global/global.html).
-The \-t option may also be specified from within
-.I less
-(using the \- command) as a way of examining a new file.
-The command ":t" is equivalent to specifying \-t from within
-.I less.
-.IP "\-T\fItagsfile\fP or \-\-tag-file=\fItagsfile\fP"
-Specifies a tags file to be used instead of "tags".
-.IP "\-u or \-\-underline-special"
-Causes backspaces and carriage returns to be treated as printable characters;
-that is, they are sent to the terminal when they appear in the input.
-.IP "\-U or \-\-UNDERLINE-SPECIAL"
-Causes backspaces, tabs and carriage returns to be
-treated as control characters;
-that is, they are handled as specified by the \-r option.
-.sp
-By default, if neither \-u nor \-U is given,
-backspaces which appear adjacent to an underscore character
-are treated specially:
-the underlined text is displayed
-using the terminal's hardware underlining capability.
-Also, backspaces which appear between two identical characters
-are treated specially:
-the overstruck text is printed
-using the terminal's hardware boldface capability.
-Other backspaces are deleted, along with the preceding character.
-Carriage returns immediately followed by a newline are deleted.
-other carriage returns are handled as specified by the \-r option.
-Text which is overstruck or underlined can be searched for
-if neither \-u nor \-U is in effect.
-.IP "\-V or \-\-version"
-Displays the version number of
-.I less.
-.IP "\-w or \-\-hilite-unread"
-Temporarily highlights the first "new" line after a forward movement
-of a full page.
-The first "new" line is the line immediately following the line previously
-at the bottom of the screen.
-Also highlights the target line after a g or p command.
-The highlight is removed at the next command which causes movement.
-The entire line is highlighted, unless the \-J option is in effect,
-in which case only the status column is highlighted.
-.IP "\-W or \-\-HILITE-UNREAD"
-Like \-w, but temporarily highlights the first new line after any
-forward movement command larger than one line.
-.IP "\-x\fIn\fP,... or \-\-tabs=\fIn\fP,..."
-Sets tab stops.
-If only one \fIn\fP is specified, tab stops are set at multiples of \fIn\fP.
-If multiple values separated by commas are specified, tab stops
-are set at those positions, and then continue with the same spacing as the
-last two.
-For example, \fI-x9,17\fP will set tabs at positions 9, 17, 25, 33, etc.
-The default for \fIn\fP is 8.
-.IP "\-X or \-\-no-init"
-Disables sending the termcap initialization and deinitialization strings
-to the terminal.
-This is sometimes desirable if the deinitialization string does
-something unnecessary, like clearing the screen.
-.IP "\-y\fIn\fP or \-\-max-forw-scroll=\fIn\fP"
-Specifies a maximum number of lines to scroll forward.
-If it is necessary to scroll forward more than \fIn\fP lines,
-the screen is repainted instead.
-The \-c or \-C option may be used to repaint from the top of
-the screen if desired.
-By default, any forward movement causes scrolling.
-.IP "\-[z]\fIn\fP or \-\-window=\fIn\fP"
-Changes the default scrolling window size to \fIn\fP lines.
-The default is one screenful.
-The z and w commands can also be used to change the window size.
-The "z" may be omitted for compatibility with some versions of
-.I more.
-If the number
-.I n
-is negative, it indicates
-.I n
-lines less than the current screen size.
-For example, if the screen is 24 lines, \fI\-z-4\fP sets the
-scrolling window to 20 lines. If the screen is resized to 40 lines,
-the scrolling window automatically changes to 36 lines.
-.IP "\-\fI\(dqcc\fP\ or\ \-\-quotes=\fIcc\fP"
-Changes the filename quoting character.
-This may be necessary if you are trying to name a file
-which contains both spaces and quote characters.
-Followed by a single character, this changes the quote character to that
-character.
-Filenames containing a space should then be surrounded by that character
-rather than by double quotes.
-Followed by two characters, changes the open quote to the first character,
-and the close quote to the second character.
-Filenames containing a space should then be preceded by the open quote
-character and followed by the close quote character.
-Note that even after the quote characters are changed, this option
-remains \-" (a dash followed by a double quote).
-.IP "\-~ or \-\-tilde"
-Normally lines after end of file are displayed as a single tilde (~).
-This option causes lines after end of file to be displayed as blank lines.
-.IP "\-# or \-\-shift"
-Specifies the default number of positions to scroll horizontally
-in the RIGHTARROW and LEFTARROW commands.
-If the number specified is zero, it sets the default number of
-positions to one half of the screen width.
-Alternately, the number may be specified as a fraction of the width
-of the screen, starting with a decimal point: .5 is half of the
-screen width, .3 is three tenths of the screen width, and so on.
-If the number is specified as a fraction, the actual number of
-scroll positions is recalculated if the terminal window is resized,
-so that the actual scroll remains at the specified fraction
-of the screen width.
-.IP "\-\-no-keypad"
-Disables sending the keypad initialization and deinitialization strings
-to the terminal.
-This is sometimes useful if the keypad strings make the numeric
-keypad behave in an undesirable manner.
-.IP "\-\-follow-name"
-Normally, if the input file is renamed while an F command is executing,
-.I less
-will continue to display the contents of the original file despite
-its name change.
-If \-\-follow-name is specified, during an F command
-.I less
-will periodically attempt to reopen the file by name.
-If the reopen succeeds and the file is a different file from the original
-(which means that a new file has been created
-with the same name as the original (now renamed) file),
-.I less
-will display the contents of that new file.
-.IP \-\-
-A command line argument of "\-\-" marks the end of option arguments.
-Any arguments following this are interpreted as filenames.
-This can be useful when viewing a file whose name begins with a "\-" or "+".
-.IP +
-If a command line option begins with \fB+\fP,
-the remainder of that option is taken to be an initial command to
-.I less.
-For example, +G tells
-.I less
-to start at the end of the file rather than the beginning,
-and +/xyz tells it to start at the first occurrence of "xyz" in the file.
-As a special case, +<number> acts like +<number>g;
-that is, it starts the display at the specified line number
-(however, see the caveat under the "g" command above).
-If the option starts with ++, the initial command applies to
-every file being viewed, not just the first one.
-The + command described previously
-may also be used to set (or change) an initial command for every file.
-
-.SH "LINE EDITING"
-When entering command line at the bottom of the screen
-(for example, a filename for the :e command,
-or the pattern for a search command),
-certain keys can be used to manipulate the command line.
-Most commands have an alternate form in [ brackets ] which can be used if
-a key does not exist on a particular keyboard.
-(Note that the forms beginning with ESC do not work
-in some MS-DOS and Windows systems because ESC is the line erase character.)
-Any of these special keys may be entered literally by preceding
-it with the "literal" character, either ^V or ^A.
-A backslash itself may also be entered literally by entering two backslashes.
-.IP "LEFTARROW [ ESC-h ]"
-Move the cursor one space to the left.
-.IP "RIGHTARROW [ ESC-l ]"
-Move the cursor one space to the right.
-.IP "^LEFTARROW [ ESC-b or ESC-LEFTARROW ]"
-(That is, CONTROL and LEFTARROW simultaneously.)
-Move the cursor one word to the left.
-.IP "^RIGHTARROW [ ESC-w or ESC-RIGHTARROW ]"
-(That is, CONTROL and RIGHTARROW simultaneously.)
-Move the cursor one word to the right.
-.IP "HOME [ ESC-0 ]"
-Move the cursor to the beginning of the line.
-.IP "END [ ESC-$ ]"
-Move the cursor to the end of the line.
-.IP "BACKSPACE"
-Delete the character to the left of the cursor,
-or cancel the command if the command line is empty.
-.IP "DELETE or [ ESC-x ]"
-Delete the character under the cursor.
-.IP "^BACKSPACE [ ESC-BACKSPACE ]"
-(That is, CONTROL and BACKSPACE simultaneously.)
-Delete the word to the left of the cursor.
-.IP "^DELETE [ ESC-X or ESC-DELETE ]"
-(That is, CONTROL and DELETE simultaneously.)
-Delete the word under the cursor.
-.IP "UPARROW [ ESC-k ]"
-Retrieve the previous command line.
-.IP "DOWNARROW [ ESC-j ]"
-Retrieve the next command line.
-.IP "TAB"
-Complete the partial filename to the left of the cursor.
-If it matches more than one filename, the first match
-is entered into the command line.
-Repeated TABs will cycle thru the other matching filenames.
-If the completed filename is a directory, a "/" is appended to the filename.
-(On MS-DOS systems, a "\e" is appended.)
-The environment variable LESSSEPARATOR can be used to specify a
-different character to append to a directory name.
-.IP "BACKTAB [ ESC-TAB ]"
-Like, TAB, but cycles in the reverse direction thru the matching filenames.
-.IP "^L"
-Complete the partial filename to the left of the cursor.
-If it matches more than one filename, all matches are entered into
-the command line (if they fit).
-.IP "^U (Unix and OS/2) or ESC (MS-DOS)"
-Delete the entire command line,
-or cancel the command if the command line is empty.
-If you have changed your line-kill character in Unix to something
-other than ^U, that character is used instead of ^U.
-
-.SH "KEY BINDINGS"
-You may define your own
-.I less
-commands by using the program
-.I lesskey
-(1)
-to create a lesskey file.
-This file specifies a set of command keys and an action
-associated with each key.
-You may also use
-.I lesskey
-to change the line-editing keys (see LINE EDITING),
-and to set environment variables.
-If the environment variable LESSKEY is set,
-.I less
-uses that as the name of the lesskey file.
-Otherwise,
-.I less
-looks in a standard place for the lesskey file:
-On Unix systems,
-.I less
-looks for a lesskey file called "$HOME/.less".
-On MS-DOS and Windows systems,
-.I less
-looks for a lesskey file called "$HOME/_less", and if it is not found there,
-then looks for a lesskey file called "_less" in any directory specified
-in the PATH environment variable.
-On OS/2 systems,
-.I less
-looks for a lesskey file called "$HOME/less.ini", and if it is not found,
-then looks for a lesskey file called "less.ini" in any directory specified
-in the INIT environment variable, and if it not found there,
-then looks for a lesskey file called "less.ini" in any directory specified
-in the PATH environment variable.
-See the
-.I lesskey
-manual page for more details.
-.P
-A system-wide lesskey file may also be set up to provide key bindings.
-If a key is defined in both a local lesskey file and in the
-system-wide file, key bindings in the local file take precedence over
-those in the system-wide file.
-If the environment variable LESSKEY_SYSTEM is set,
-.I less
-uses that as the name of the system-wide lesskey file.
-Otherwise,
-.I less
-looks in a standard place for the system-wide lesskey file:
-On Unix systems, the system-wide lesskey file is /usr/local/etc/sysless.
-(However, if
-.I less
-was built with a different sysconf directory than /usr/local/etc,
-that directory is where the sysless file is found.)
-On MS-DOS and Windows systems, the system-wide lesskey file is c:\e_sysless.
-On OS/2 systems, the system-wide lesskey file is c:\esysless.ini.
-
-.SH "INPUT PREPROCESSOR"
-You may define an "input preprocessor" for
-.I less.
-Before
-.I less
-opens a file, it first gives your input preprocessor a chance to modify the
-way the contents of the file are displayed.
-An input preprocessor is simply an executable program (or shell script),
-which writes the contents of the file to a different file,
-called the replacement file.
-The contents of the replacement file are then displayed
-in place of the contents of the original file.
-However, it will appear to the user as if the original file is opened;
-that is,
-.I less
-will display the original filename as the name of the current file.
-.PP
-An input preprocessor receives one command line argument, the original filename,
-as entered by the user.
-It should create the replacement file, and when finished,
-print the name of the replacement file to its standard output.
-If the input preprocessor does not output a replacement filename,
-.I less
-uses the original file, as normal.
-The input preprocessor is not called when viewing standard input.
-To set up an input preprocessor, set the LESSOPEN environment variable
-to a command line which will invoke your input preprocessor.
-This command line should include one occurrence of the string "%s",
-which will be replaced by the filename
-when the input preprocessor command is invoked.
-.PP
-When
-.I less
-closes a file opened in such a way, it will call another program,
-called the input postprocessor,
-which may perform any desired clean-up action (such as deleting the
-replacement file created by LESSOPEN).
-This program receives two command line arguments, the original filename
-as entered by the user, and the name of the replacement file.
-To set up an input postprocessor, set the LESSCLOSE environment variable
-to a command line which will invoke your input postprocessor.
-It may include two occurrences of the string "%s";
-the first is replaced with the original name of the file and
-the second with the name of the replacement file,
-which was output by LESSOPEN.
-.PP
-For example, on many Unix systems, these two scripts will allow you
-to keep files in compressed format, but still let
-.I less
-view them directly:
-.PP
-lessopen.sh:
-.br
- #! /bin/sh
-.br
- case "$1" in
-.br
- *.Z) uncompress -\c $1 >/tmp/less.$$ 2>/dev/null
-.br
- if [ \-s /tmp/less.$$ ]; then
-.br
- echo /tmp/less.$$
-.br
- else
-.br
- rm \-f /tmp/less.$$
-.br
- fi
-.br
- ;;
-.br
- esac
-.PP
-lessclose.sh:
-.br
- #! /bin/sh
-.br
- rm $2
-.PP
-To use these scripts, put them both where they can be executed and
-set LESSOPEN="lessopen.sh\ %s", and
-LESSCLOSE="lessclose.sh\ %s\ %s".
-More complex LESSOPEN and LESSCLOSE scripts may be written
-to accept other types of compressed files, and so on.
-.PP
-It is also possible to set up an input preprocessor to
-pipe the file data directly to
-.I less,
-rather than putting the data into a replacement file.
-This avoids the need to decompress the entire file before
-starting to view it.
-An input preprocessor that works this way is called an input pipe.
-An input pipe, instead of writing the name of a replacement file on
-its standard output,
-writes the entire contents of the replacement file on its standard output.
-If the input pipe does not write any characters on its standard output,
-then there is no replacement file and
-.I less
-uses the original file, as normal.
-To use an input pipe,
-make the first character in the LESSOPEN environment variable a
-vertical bar (|) to signify that the input preprocessor is an input pipe.
-.PP
-For example, on many Unix systems, this script will work like the
-previous example scripts:
-.PP
-lesspipe.sh:
-.br
- #! /bin/sh
-.br
- case "$1" in
-.br
- *.Z) uncompress \-c $1 2>/dev/null
-.br
- ;;
-.br
- esac
-.br
-.PP
-To use this script, put it where it can be executed and set
-LESSOPEN="|lesspipe.sh %s".
-When an input pipe is used, a LESSCLOSE postprocessor can be used,
-but it is usually not necessary since there is no replacement file
-to clean up.
-In this case, the replacement file name passed to the LESSCLOSE
-postprocessor is "\-".
-.PP
-For compatibility with previous versions of
-.I less,
-the input preprocessor or pipe is not used if
-.I less
-is viewing standard input.
-However, if the first character of LESSOPEN is a dash (\-),
-the input preprocessor is used on standard input as well as other files.
-In this case, the dash is not considered to be part of
-the preprocessor command.
-If standard input is being viewed, the input preprocessor is passed
-a file name consisting of a single dash.
-Similarly, if the first two characters of LESSOPEN are vertical bar and dash
-(|\-), the input pipe is used on standard input as well as other files.
-Again, in this case the dash is not considered to be part of
-the input pipe command.
-
-.SH "NATIONAL CHARACTER SETS"
-There are three types of characters in the input file:
-.IP "normal characters"
-can be displayed directly to the screen.
-.IP "control characters"
-should not be displayed directly, but are expected to be found
-in ordinary text files (such as backspace and tab).
-.IP "binary characters"
-should not be displayed directly and are not expected to be found
-in text files.
-.PP
-A "character set" is simply a description of which characters are to
-be considered normal, control, and binary.
-The LESSCHARSET environment variable may be used to select a character set.
-Possible values for LESSCHARSET are:
-.IP ascii
-BS, TAB, NL, CR, and formfeed are control characters,
-all chars with values between 32 and 126 are normal,
-and all others are binary.
-.IP iso8859
-Selects an ISO 8859 character set.
-This is the same as ASCII, except characters between 160 and 255 are
-treated as normal characters.
-.IP latin1
-Same as iso8859.
-.IP latin9
-Same as iso8859.
-.IP dos
-Selects a character set appropriate for MS-DOS.
-.IP ebcdic
-Selects an EBCDIC character set.
-.IP IBM-1047
-Selects an EBCDIC character set used by OS/390 Unix Services.
-This is the EBCDIC analogue of latin1. You get similar results
-by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US
-in your environment.
-.IP koi8-r
-Selects a Russian character set.
-.IP next
-Selects a character set appropriate for NeXT computers.
-.IP utf-8
-Selects the UTF-8 encoding of the ISO 10646 character set.
-UTF-8 is special in that it supports multi-byte characters in the input file.
-It is the only character set that supports multi-byte characters.
-.IP windows
-Selects a character set appropriate for Microsoft Windows (cp 1251).
-.PP
-In rare cases, it may be desired to tailor
-.I less
-to use a character set other than the ones definable by LESSCHARSET.
-In this case, the environment variable LESSCHARDEF can be used
-to define a character set.
-It should be set to a string where each character in the string represents
-one character in the character set.
-The character "." is used for a normal character, "c" for control,
-and "b" for binary.
-A decimal number may be used for repetition.
-For example, "bccc4b." would mean character 0 is binary,
-1, 2 and 3 are control, 4, 5, 6 and 7 are binary, and 8 is normal.
-All characters after the last are taken to be the same as the last,
-so characters 9 through 255 would be normal.
-(This is an example, and does not necessarily
-represent any real character set.)
-.PP
-This table shows the value of LESSCHARDEF which is equivalent
-to each of the possible values for LESSCHARSET:
-.sp
- ascii\ 8bcccbcc18b95.b
-.br
- dos\ \ \ 8bcccbcc12bc5b95.b.
-.br
- ebcdic 5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
-.br
- \ \ \ \ \ \ 9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
-.br
- IBM-1047 4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
-.br
- \ \ \ \ \ \ 191.b
-.br
- iso8859 8bcccbcc18b95.33b.
-.br
- koi8-r 8bcccbcc18b95.b128.
-.br
- latin1 8bcccbcc18b95.33b.
-.br
- next\ \ 8bcccbcc18b95.bb125.bb
-.PP
-If neither LESSCHARSET nor LESSCHARDEF is set,
-but any of the strings "UTF-8", "UTF8", "utf-8" or "utf8"
-is found in the LC_ALL, LC_TYPE or LANG
-environment variables, then the default character set is utf-8.
-.PP
-If that string is not found, but your system supports the
-.I setlocale
-interface,
-.I less
-will use setlocale to determine the character set.
-setlocale is controlled by setting the LANG or LC_CTYPE environment
-variables.
-.PP
-Finally, if the
-.I setlocale
-interface is also not available, the default character set is latin1.
-.PP
-Control and binary characters are displayed in standout (reverse video).
-Each such character is displayed in caret notation if possible
-(e.g. ^A for control-A). Caret notation is used only if
-inverting the 0100 bit results in a normal printable character.
-Otherwise, the character is displayed as a hex number in angle brackets.
-This format can be changed by
-setting the LESSBINFMT environment variable.
-LESSBINFMT may begin with a "*" and one character to select
-the display attribute:
-"*k" is blinking, "*d" is bold, "*u" is underlined, "*s" is standout,
-and "*n" is normal.
-If LESSBINFMT does not begin with a "*", normal attribute is assumed.
-The remainder of LESSBINFMT is a string which may include one
-printf-style escape sequence (a % followed by x, X, o, d, etc.).
-For example, if LESSBINFMT is "*u[%x]", binary characters
-are displayed in underlined hexadecimal surrounded by brackets.
-The default if no LESSBINFMT is specified is "*s<%X>".
-The default if no LESSBINFMT is specified is "*s<%02X>".
-Warning: the result of expanding the character via LESSBINFMT must
-be less than 31 characters.
-.PP
-When the character set is utf-8, the LESSUTFBINFMT environment variable
-acts similarly to LESSBINFMT but it applies to Unicode code points
-that were successfully decoded but are unsuitable for display (e.g.,
-unassigned code points).
-Its default value is "<U+%04lX>".
-Note that LESSUTFBINFMT and LESSBINFMT share their display attribute
-setting ("*x") so specifying one will affect both;
-LESSUTFBINFMT is read after LESSBINFMT so its setting, if any,
-will have priority.
-Problematic octets in a UTF-8 file (octets of a truncated sequence,
-octets of a complete but non-shortest form sequence, illegal octets,
-and stray trailing octets)
-are displayed individually using LESSBINFMT so as to facilitate diagnostic
-of how the UTF-8 file is ill-formed.
-
-.SH "PROMPTS"
-The \-P option allows you to tailor the prompt to your preference.
-The string given to the \-P option replaces the specified prompt string.
-Certain characters in the string are interpreted specially.
-The prompt mechanism is rather complicated to provide flexibility,
-but the ordinary user need not understand the details of constructing
-personalized prompt strings.
-.sp
-A percent sign followed by a single character is expanded
-according to what the following character is:
-.IP "%b\fIX\fP"
-Replaced by the byte offset into the current input file.
-The b is followed by a single character (shown as \fIX\fP above)
-which specifies the line whose byte offset is to be used.
-If the character is a "t", the byte offset of the top line in the
-display is used,
-an "m" means use the middle line,
-a "b" means use the bottom line,
-a "B" means use the line just after the bottom line,
-and a "j" means use the "target" line, as specified by the \-j option.
-.IP "%B"
-Replaced by the size of the current input file.
-.IP "%c"
-Replaced by the column number of the text appearing in the first
-column of the screen.
-.IP "%d\fIX\fP"
-Replaced by the page number of a line in the input file.
-The line to be used is determined by the \fIX\fP, as with the %b option.
-.IP "%D"
-Replaced by the number of pages in the input file,
-or equivalently, the page number of the last line in the input file.
-.IP "%E"
-Replaced by the name of the editor (from the VISUAL environment variable,
-or the EDITOR environment variable if VISUAL is not defined).
-See the discussion of the LESSEDIT feature below.
-.IP "%f"
-Replaced by the name of the current input file.
-.IP "%i"
-Replaced by the index of the current file in the list of
-input files.
-.IP "%l\fIX\fP"
-Replaced by the line number of a line in the input file.
-The line to be used is determined by the \fIX\fP, as with the %b option.
-.IP "%L"
-Replaced by the line number of the last line in the input file.
-.IP "%m"
-Replaced by the total number of input files.
-.IP "%p\fIX\fP"
-Replaced by the percent into the current input file, based on byte offsets.
-The line used is determined by the \fIX\fP as with the %b option.
-.IP "%P\fIX\fP"
-Replaced by the percent into the current input file, based on line numbers.
-The line used is determined by the \fIX\fP as with the %b option.
-.IP "%s"
-Same as %B.
-.IP "%t"
-Causes any trailing spaces to be removed.
-Usually used at the end of the string, but may appear anywhere.
-.IP "%x"
-Replaced by the name of the next input file in the list.
-.PP
-If any item is unknown (for example, the file size if input
-is a pipe), a question mark is printed instead.
-.PP
-The format of the prompt string can be changed
-depending on certain conditions.
-A question mark followed by a single character acts like an "IF":
-depending on the following character, a condition is evaluated.
-If the condition is true, any characters following the question mark
-and condition character, up to a period, are included in the prompt.
-If the condition is false, such characters are not included.
-A colon appearing between the question mark and the
-period can be used to establish an "ELSE": any characters between
-the colon and the period are included in the string if and only if
-the IF condition is false.
-Condition characters (which follow a question mark) may be:
-.IP "?a"
-True if any characters have been included in the prompt so far.
-.IP "?b\fIX\fP"
-True if the byte offset of the specified line is known.
-.IP "?B"
-True if the size of current input file is known.
-.IP "?c"
-True if the text is horizontally shifted (%c is not zero).
-.IP "?d\fIX\fP"
-True if the page number of the specified line is known.
-.IP "?e"
-True if at end-of-file.
-.IP "?f"
-True if there is an input filename
-(that is, if input is not a pipe).
-.IP "?l\fIX\fP"
-True if the line number of the specified line is known.
-.IP "?L"
-True if the line number of the last line in the file is known.
-.IP "?m"
-True if there is more than one input file.
-.IP "?n"
-True if this is the first prompt in a new input file.
-.IP "?p\fIX\fP"
-True if the percent into the current input file, based on byte offsets,
-of the specified line is known.
-.IP "?P\fIX\fP"
-True if the percent into the current input file, based on line numbers,
-of the specified line is known.
-.IP "?s"
-Same as "?B".
-.IP "?x"
-True if there is a next input file
-(that is, if the current input file is not the last one).
-.PP
-Any characters other than the special ones
-(question mark, colon, period, percent, and backslash)
-become literally part of the prompt.
-Any of the special characters may be included in the prompt literally
-by preceding it with a backslash.
-.PP
-Some examples:
-.sp
-?f%f:Standard input.
-.sp
-This prompt prints the filename, if known;
-otherwise the string "Standard input".
-.sp
-?f%f .?ltLine %lt:?pt%pt\e%:?btByte %bt:-...
-.sp
-This prompt would print the filename, if known.
-The filename is followed by the line number, if known,
-otherwise the percent if known, otherwise the byte offset if known.
-Otherwise, a dash is printed.
-Notice how each question mark has a matching period,
-and how the % after the %pt
-is included literally by escaping it with a backslash.
-.sp
-?n?f%f\ .?m(file\ %i\ of\ %m)\ ..?e(END)\ ?x-\ Next\e:\ %x..%t
-.sp
-This prints the filename if this is the first prompt in a file,
-followed by the "file N of N" message if there is more
-than one input file.
-Then, if we are at end-of-file, the string "(END)" is printed
-followed by the name of the next file, if there is one.
-Finally, any trailing spaces are truncated.
-This is the default prompt.
-For reference, here are the defaults for
-the other two prompts (\-m and \-M respectively).

-.PP
-The prompt expansion features are also used for another purpose:
-if an environment variable LESSEDIT is defined, it is used
-as the command to be executed when the v command is invoked.
-The LESSEDIT string is expanded in the same way as the prompt strings.
-The default value for LESSEDIT is:
-.nf

- %E\ ?lm+%lm.\ %f
-.sp
-.fi
-Note that this expands to the editor name, followed by a + and the
-line number, followed by the file name.
-If your editor does not accept the "+linenumber" syntax, or has other
-differences in invocation syntax, the LESSEDIT variable can be
-changed to modify this default.
-
-.SH SECURITY
-When the environment variable LESSSECURE is set to 1,
-.I less
-runs in a "secure" mode.
-This means these features are disabled:
-.RS
-.IP "!"
-the shell command
-.IP "|"
-the pipe command
-.IP ":e"
-the examine command.
-.IP "v"
-the editing command
-.IP "s \-o"
-log files
-.IP "\-k"
-use of lesskey files
-.IP "\-t"
-use of tags files
-.IP " "
-metacharacters in filenames, such as *
-.IP " "
-filename completion (TAB, ^L)
-.RE
-.PP
-Less can also be compiled to be permanently in "secure" mode.
-
-.SH "COMPATIBILITY WITH MORE"
-If the environment variable LESS_IS_MORE is set to 1,
-or if the program is invoked via a file link named "more",
-.I less
-behaves (mostly) in conformance with the POSIX "more" command specification.
-In this mode, less behaves differently in these ways:
-.PP
-The \-e option works differently.
-If the \-e option is not set,
-.I less
-behaves as if the \-E option were set.
-If the \-e option is set,
-.I less
-behaves as if the \-e and \-F options were set.
-.PP
-The \-m option works differently.
-If the \-m option is not set, the medium prompt is used,
-and it is prefixed with the string "--More--".
-If the \-m option is set, the short prompt is used.
-.PP
-The \-n option acts like the \-z option.
-The normal behavior of the \-n option is unavailable in this mode.
-.PP
-The parameter to the \-p option is taken to be a
-.I less
-command rather than a search pattern.
-.PP
-The LESS environment variable is ignored,
-and the MORE environment variable is used in its place.
-
-.SH "ENVIRONMENT VARIABLES"
-Environment variables may be specified either in the system environment
-as usual, or in a
-.I lesskey
-(1) file.

+.SH DESCRIPTION
+.I Less
+is a program similar to
+.I more
+(1), but which allows backward movement
+in the file as well as forward movement.
+Also,
+.I less
+does not have to read the entire input file before starting,
+so with large input files it starts up faster than text editors like
+.I vi
+(1).
+.I Less
+uses termcap (or terminfo on some systems),
+so it can run on a variety of terminals.
+There is even limited support for hardcopy terminals.
+(On a hardcopy terminal, lines which should be printed at the top
+of the screen are prefixed with a caret.)
+.PP
+Commands are based on both
+.I more
+and
+.I vi.
+Commands may be preceded by a decimal number,
+called N in the descriptions below.
+The number is used by some commands, as indicated.
+
+.SH COMMANDS
+In the following descriptions, ^X means control-X.
+ESC stands for the ESCAPE key; for example ESC-v means the
+two character sequence "ESCAPE", then "v".
+.IP "h or H"
+Help: display a summary of these commands.
+If you forget all the other commands, remember this one.
+.IP "SPACE or ^V or f or ^F"
+Scroll forward N lines, default one window (see option \-z below).
+If N is more than the screen size, only the final screenful is displayed.
+Warning: some systems use ^V as a special literalization character.
+.IP "z"
+Like SPACE, but if N is specified, it becomes the new window size.
+.IP "ESC-SPACE"
+Like SPACE, but scrolls a full screenful, even if it reaches
+end-of-file in the process.
+.IP "ENTER or RETURN or ^N or e or ^E or j or ^J"
+Scroll forward N lines, default 1.
+The entire N lines are displayed, even if N is more than the screen size.
+.IP "d or ^D"
+Scroll forward N lines, default one half of the screen size.
+If N is specified, it becomes the new default for
+subsequent d and u commands.
+.IP "b or ^B or ESC-v"
+Scroll backward N lines, default one window (see option \-z below).
+If N is more than the screen size, only the final screenful is displayed.
+.IP "w"
+Like ESC-v, but if N is specified, it becomes the new window size.
+.IP "y or ^Y or ^P or k or ^K"
+Scroll backward N lines, default 1.
+The entire N lines are displayed, even if N is more than the screen size.
+Warning: some systems use ^Y as a special job control character.
+.IP "u or ^U"
+Scroll backward N lines, default one half of the screen size.
+If N is specified, it becomes the new default for
+subsequent d and u commands.
+.IP "ESC-) or RIGHTARROW"
+Scroll horizontally right N characters, default half the screen width
+(see the \-# option).
+If a number N is specified, it becomes the default for future RIGHTARROW
+and LEFTARROW commands.
+While the text is scrolled, it acts as though the \-S option
+(chop lines) were in effect.
+.IP "ESC-( or LEFTARROW"
+Scroll horizontally left N characters, default half the screen width
+(see the \-# option).
+If a number N is specified, it becomes the default for future RIGHTARROW
+and LEFTARROW commands.
+.IP "r or ^R or ^L"
+Repaint the screen.
+.IP R
+Repaint the screen, discarding any buffered input.
+Useful if the file is changing while it is being viewed.
+.IP "F"
+Scroll forward, and keep trying to read when the
+end of file is reached.
+Normally this command would be used when already at the end of the file.
+It is a way to monitor the tail of a file which is growing
+while it is being viewed.
+(The behavior is similar to the "tail \-f" command.)
+.IP "ESC-F"
+Like F, but as soon as a line is found which matches
+the last search pattern, the terminal bell is rung
+and forward scrolling stops.
+.IP "g or < or ESC-<"
+Go to line N in the file, default 1 (beginning of file).
+(Warning: this may be slow if N is large.)
+.IP "G or > or ESC->"
+Go to line N in the file, default the end of the file.
+(Warning: this may be slow if N is large,
+or if N is not specified and
+standard input, rather than a file, is being read.)
+.IP "p or %"
+Go to a position N percent into the file.
+N should be between 0 and 100, and may contain a decimal point.
+.IP "P"
+Go to the line containing byte offset N in the file.
+.IP "{"
+If a left curly bracket appears in the top line displayed
+on the screen,
+the { command will go to the matching right curly bracket.
+The matching right curly bracket is positioned on the bottom
+line of the screen.
+If there is more than one left curly bracket on the top line,
+a number N may be used to specify the N-th bracket on the line.
+.IP "}"
+If a right curly bracket appears in the bottom line displayed
+on the screen,
+the } command will go to the matching left curly bracket.
+The matching left curly bracket is positioned on the top
+line of the screen.
+If there is more than one right curly bracket on the top line,
+a number N may be used to specify the N-th bracket on the line.
+.IP "("
+Like {, but applies to parentheses rather than curly brackets.
+.IP ")"
+Like }, but applies to parentheses rather than curly brackets.
+.IP "["
+Like {, but applies to square brackets rather than curly brackets.
+.IP "]"
+Like }, but applies to square brackets rather than curly brackets.
+.IP "ESC-^F"
+Followed by two characters,
+acts like {, but uses the two characters as open and close brackets,
+respectively.
+For example, "ESC ^F < >" could be used to
+go forward to the > which matches the < in the top displayed line.
+.IP "ESC-^B"
+Followed by two characters,
+acts like }, but uses the two characters as open and close brackets,
+respectively.
+For example, "ESC ^B < >" could be used to
+go backward to the < which matches the > in the bottom displayed line.
+.IP m
+Followed by any lowercase letter,
+marks the current position with that letter.
+.IP "'"
+(Single quote.)
+Followed by any lowercase letter, returns to the position which
+was previously marked with that letter.
+Followed by another single quote, returns to the position at
+which the last "large" movement command was executed.
+Followed by a ^ or $, jumps to the beginning or end of the
+file respectively.
+Marks are preserved when a new file is examined,
+so the ' command can be used to switch between input files.
+.IP "^X^X"
+Same as single quote.
+.IP /pattern
+Search forward in the file for the N-th line containing the pattern.
+N defaults to 1.
+The pattern is a regular expression, as recognized by
+the regular expression library supplied by your system.
+The search starts at the first line displayed
+(but see the \-a and \-j options, which change this).
+.sp
+Certain characters are special
+if entered at the beginning of the pattern;
+they modify the type of search rather than become part of the pattern:
+.RS
+.IP "^N or !"
+Search for lines which do NOT match the pattern.
+.IP "^E or *"
+Search multiple files.
+That is, if the search reaches the END of the current file
+without finding a match,
+the search continues in the next file in the command line list.
+.IP "^F or @"
+Begin the search at the first line of the FIRST file
+in the command line list,
+regardless of what is currently displayed on the screen
+or the settings of the \-a or \-j options.
+.IP "^K"
+Highlight any text which matches the pattern on the current screen,
+but don't move to the first match (KEEP current position).
+.IP "^R"
+Don't interpret regular expression metacharacters;
+that is, do a simple textual comparison.
+.RE
+.IP ?pattern
+Search backward in the file for the N-th line containing the pattern.
+The search starts at the line immediately before the top line displayed.
+.sp
+Certain characters are special as in the / command:
+.RS
+.IP "^N or !"
+Search for lines which do NOT match the pattern.
+.IP "^E or *"
+Search multiple files.
+That is, if the search reaches the beginning of the current file
+without finding a match,
+the search continues in the previous file in the command line list.
+.IP "^F or @"
+Begin the search at the last line of the last file
+in the command line list,
+regardless of what is currently displayed on the screen
+or the settings of the \-a or \-j options.
+.IP "^K"
+As in forward searches.
+.IP "^R"
+As in forward searches.
+.RE
+.IP "ESC-/pattern"
+Same as "/*".
+.IP "ESC-?pattern"
+Same as "?*".
+.IP n
+Repeat previous search, for N-th line containing the last pattern.
+If the previous search was modified by ^N, the search is made for the
+N-th line NOT containing the pattern.
+If the previous search was modified by ^E, the search continues
+in the next (or previous) file if not satisfied in the current file.
+If the previous search was modified by ^R, the search is done
+without using regular expressions.
+There is no effect if the previous search was modified by ^F or ^K.
+.IP N
+Repeat previous search, but in the reverse direction.
+.IP "ESC-n"
+Repeat previous search, but crossing file boundaries.
+The effect is as if the previous search were modified by *.
+.IP "ESC-N"
+Repeat previous search, but in the reverse direction
+and crossing file boundaries.
+.IP "ESC-u"
+Undo search highlighting.
+Turn off highlighting of strings matching the current search pattern.
+If highlighting is already off because of a previous ESC-u command,
+turn highlighting back on.
+Any search command will also turn highlighting back on.
+(Highlighting can also be disabled by toggling the \-G option;
+in that case search commands do not turn highlighting back on.)
+.IP "&pattern"
+Display only lines which match the pattern;
+lines which do not match the pattern are not displayed.
+If pattern is empty (if you type & immediately followed by ENTER),
+any filtering is turned off, and all lines are displayed.
+While filtering is in effect, an ampersand is displayed at the
+beginning of the prompt,
+as a reminder that some lines in the file may be hidden.
+.sp
+Certain characters are special as in the / command:
+.RS
+.IP "^N or !"
+Display only lines which do NOT match the pattern.
+.IP "^R"
+Don't interpret regular expression metacharacters;
+that is, do a simple textual comparison.
+.RE
+.IP ":e [filename]"
+Examine a new file.
+If the filename is missing, the "current" file (see the :n and :p commands
+below) from the list of files in the command line is re-examined.
+A percent sign (%) in the filename is replaced by the name of the
+current file.
+A pound sign (#) is replaced by the name of the previously examined file.
+However, two consecutive percent signs are simply
+replaced with a single percent sign.
+This allows you to enter a filename that contains a percent sign
+in the name.
+Similarly, two consecutive pound signs are replaced with a single pound sign.
+The filename is inserted into the command line list of files
+so that it can be seen by subsequent :n and :p commands.
+If the filename consists of several files, they are all inserted into
+the list of files and the first one is examined.
+If the filename contains one or more spaces,
+the entire filename should be enclosed in double quotes
+(also see the \-" option).
+.IP "^X^V or E"
+Same as :e.
+Warning: some systems use ^V as a special literalization character.
+On such systems, you may not be able to use ^V.
+.IP ":n"
+Examine the next file (from the list of files given in the command line).
+If a number N is specified, the N-th next file is examined.
+.IP ":p"
+Examine the previous file in the command line list.
+If a number N is specified, the N-th previous file is examined.
+.IP ":x"
+Examine the first file in the command line list.
+If a number N is specified, the N-th file in the list is examined.
+.IP ":d"
+Remove the current file from the list of files.
+.IP "t"
+Go to the next tag, if there were more than one matches for the current tag.
+See the \-t option for more details about tags.
+.IP "T"
+Go to the previous tag, if there were more than one matches for the current tag.
+.IP "= or ^G or :f"
+Prints some information about the file being viewed,
+including its name
+and the line number and byte offset of the bottom line being displayed.
+If possible, it also prints the length of the file,
+the number of lines in the file
+and the percent of the file above the last displayed line.
+.IP \-
+Followed by one of the command line option letters (see OPTIONS below),
+this will change the setting of that option
+and print a message describing the new setting.
+If a ^P (CONTROL-P) is entered immediately after the dash,
+the setting of the option is changed but no message is printed.
+If the option letter has a numeric value (such as \-b or \-h),
+or a string value (such as \-P or \-t),
+a new value may be entered after the option letter.
+If no new value is entered, a message describing
+the current setting is printed and nothing is changed.
+.IP \-\-
+Like the \- command, but takes a long option name (see OPTIONS below)
+rather than a single option letter.
+You must press ENTER or RETURN after typing the option name.
+A ^P immediately after the second dash suppresses printing of a
+message describing the new setting, as in the \- command.
+.IP \-+
+Followed by one of the command line option letters
+this will reset the option to its default setting
+and print a message describing the new setting.
+(The "\-+\fIX\fP" command does the same thing
+as "\-+\fIX\fP" on the command line.)
+This does not work for string-valued options.
+.IP \-\-+
+Like the \-+ command, but takes a long option name
+rather than a single option letter.
+.IP \-!
+Followed by one of the command line option letters,
+this will reset the option to the "opposite" of its default setting
+and print a message describing the new setting.
+This does not work for numeric or string-valued options.
+.IP \-\-!
+Like the \-! command, but takes a long option name
+rather than a single option letter.
+.IP _
+(Underscore.)
+Followed by one of the command line option letters,
+this will print a message describing the current setting of that option.
+The setting of the option is not changed.
+.IP __
+(Double underscore.)
+Like the _ (underscore) command, but takes a long option name
+rather than a single option letter.
+You must press ENTER or RETURN after typing the option name.
+.IP +cmd
+Causes the specified cmd to be executed each time a new file is examined.
+For example, +G causes
+.I less
+to initially display each file starting at the end
+rather than the beginning.
+.IP V
+Prints the version number of
+.I less
+being run.
+.IP "q or Q or :q or :Q or ZZ"
+Exits
+.I less.
+.PP
+The following
+four
+commands may or may not be valid, depending on your particular installation.
+.PP
+.IP v
+Invokes an editor to edit the current file being viewed.
+The editor is taken from the environment variable VISUAL if defined,
+or EDITOR if VISUAL is not defined,
+or defaults to "vi" if neither VISUAL nor EDITOR is defined.
+See also the discussion of LESSEDIT under the section on PROMPTS below.
+.IP "! shell-command"
+Invokes a shell to run the shell-command given.
+A percent sign (%) in the command is replaced by the name of the
+current file.
+A pound sign (#) is replaced by the name of the previously examined file.
+"!!" repeats the last shell command.
+"!" with no shell command simply invokes a shell.
+On Unix systems, the shell is taken from the environment variable SHELL,
+or defaults to "sh".
+On MS-DOS and OS/2 systems, the shell is the normal command processor.
+.IP "| <m> shell-command"
+<m> represents any mark letter.
+Pipes a section of the input file to the given shell command.
+The section of the file to be piped is between the first line on
+the current screen and the position marked by the letter.
+<m> may also be ^ or $ to indicate beginning or end of file respectively.
+If <m> is . or newline, the current screen is piped.
+.IP "s filename"
+Save the input to a file.
+This only works if the input is a pipe, not an ordinary file.
+.PP
+.SH OPTIONS
+Command line options are described below.
+Most options may be changed while
+.I less
+is running, via the "\-" command.
+.PP
+Most options may be given in one of two forms:
+either a dash followed by a single letter,
+or two dashes followed by a long option name.
+A long option name may be abbreviated as long as
+the abbreviation is unambiguous.
+For example, \-\-quit-at-eof may be abbreviated \-\-quit, but not
+--qui, since both \-\-quit-at-eof and \-\-quiet begin with \-\-qui.
+Some long option names are in uppercase, such as \-\-QUIT-AT-EOF, as
+distinct from \-\-quit-at-eof.
+Such option names need only have their first letter capitalized;
+the remainder of the name may be in either case.
+For example, \-\-Quit-at-eof is equivalent to \-\-QUIT-AT-EOF.
+.PP
+Options are also taken from the environment variable "LESS".
+For example,
+to avoid typing "less \-options ..." each time
+.I less
+is invoked, you might tell
+.I csh:
+.sp
+setenv LESS "-options"
+.sp
+or if you use
+.I sh:
+.sp
+LESS="-options"; export LESS
+.sp
+On MS-DOS, you don't need the quotes, but you should replace any
+percent signs in the options string by double percent signs.
+.sp
+The environment variable is parsed before the command line,
+so command line options override the LESS environment variable.
+If an option appears in the LESS variable, it can be reset
+to its default value on the command line by beginning the command
+line option with "\-+".
+.sp
+Some options like \-k or \-D require a string to follow the option letter.
+The string for that option is considered to end when a dollar sign ($) is found.
+For example, you can set two \-D options on MS-DOS like this:
+.sp
+LESS="Dn9.1$Ds4.1"
+.sp
+If the --use-backslash option appears earlier in the options, then
+a dollar sign or backslash may be included literally in an option string
+by preceding it with a backslash.
+If the --use-backslash option is not in effect, then backslashes are
+not treated specially, and there is no way to include a dollar sign
+in the option string.
+.IP "\-? or \-\-help"
+This option displays a summary of the commands accepted by
+.I less
+(the same as the h command).
+(Depending on how your shell interprets the question mark,
+it may be necessary to quote the question mark, thus: "\-\e?".)
+.IP "\-a or \-\-search-skip-screen"
+By default, forward searches start at the top of the displayed screen
+and backwards searches start at the bottom of the displayed screen
+(except for repeated searches invoked by the n or N commands,
+which start after or before the "target" line respectively;
+see the \-j option for more about the target line).
+The \-a option causes forward searches to instead start at
+the bottom of the screen
+and backward searches to start at the top of the screen,
+thus skipping all lines displayed on the screen.
+.IP "\-A or \-\-SEARCH-SKIP-SCREEN"
+Causes all forward searches (not just non-repeated searches)
+to start just after the target line, and all backward searches
+to start just before the target line.
+Thus, forward searches will skip part of the displayed screen
+(from the first line up to and including the target line).
+Similarly backwards searches will skip the displayed screen
+from the last line up to and including the target line.
+This was the default behavior in less versions prior to 441.
+.IP "\-b\fIn\fP or \-\-buffers=\fIn\fP"
+Specifies the amount of buffer space
+.I less
+will use for each file, in units of kilobytes (1024 bytes).
+By default 64K of buffer space is used for each file
+(unless the file is a pipe; see the \-B option).
+The \-b option specifies instead that \fIn\fP kilobytes of
+buffer space should be used for each file.
+If \fIn\fP is \-1, buffer space is unlimited; that is,
+the entire file can be read into memory.
+.IP "\-B or \-\-auto-buffers"
+By default, when data is read from a pipe,
+buffers are allocated automatically as needed.
+If a large amount of data is read from the pipe, this can cause
+a large amount of memory to be allocated.
+The \-B option disables this automatic allocation of buffers for pipes,
+so that only 64K
+(or the amount of space specified by the \-b option)
+is used for the pipe.
+Warning: use of \-B can result in erroneous display, since only the
+most recently viewed part of the piped data is kept in memory;
+any earlier data is lost.
+.IP "\-c or \-\-clear-screen"
+Causes full screen repaints to be painted from the top line down.
+By default,
+full screen repaints are done by scrolling from the bottom of the screen.
+.IP "\-C or \-\-CLEAR-SCREEN"
+Same as \-c, for compatibility with older versions of
+.I less.
+.IP "\-d or \-\-dumb"
+The \-d option suppresses the error message
+normally displayed if the terminal is dumb;
+that is, lacks some important capability,
+such as the ability to clear the screen or scroll backward.
+The \-d option does not otherwise change the behavior of
+.I less
+on a dumb terminal.
+.IP "\-D\fBx\fP\fIcolor\fP or \-\-color=\fBx\fP\fIcolor\fP"
+[MS-DOS only]
+Sets the color of the text displayed.
+\fBx\fP is a single character which selects the type of text whose color is
+being set: n=normal, s=standout, d=bold, u=underlined, k=blink.
+\fIcolor\fP is a pair of numbers separated by a period.
+The first number selects the foreground color and the second selects
+the background color of the text.
+A single number \fIN\fP is the same as \fIN.M\fP,
+where \fIM\fP is the normal background color.
+
+.IP "\-e or \-\-quit-at-eof"
+Causes
+.I less
+to automatically exit
+the second time it reaches end-of-file.
+By default, the only way to exit
+.I less
+is via the "q" command.
+.IP "\-E or \-\-QUIT-AT-EOF"
+Causes
+.I less
+to automatically exit the first time it reaches end-of-file.
+.IP "\-f or \-\-force"
+Forces non-regular files to be opened.
+(A non-regular file is a directory or a device special file.)
+Also suppresses the warning message when a binary file is opened.
+By default,
+.I less
+will refuse to open non-regular files.
+Note that some operating systems will not allow directories
+to be read, even if \-f is set.
+.IP "\-F or \-\-quit-if-one-screen"
+Causes
+.I less
+to automatically exit
+if the entire file can be displayed on the first screen.
+.IP "\-g or \-\-hilite-search"
+Normally,
+.I less
+will highlight ALL strings which match the last search command.
+The \-g option changes this behavior to highlight only the particular string
+which was found by the last search command.
+This can cause
+.I less
+to run somewhat faster than the default.
+.IP "\-G or \-\-HILITE-SEARCH"
+The \-G option suppresses all highlighting of strings found by search commands.
+.IP "\-h\fIn\fP or \-\-max-back-scroll=\fIn\fP"
+Specifies a maximum number of lines to scroll backward.
+If it is necessary to scroll backward more than \fIn\fP lines,
+the screen is repainted in a forward direction instead.
+(If the terminal does not have the ability to scroll
+backward, \-h0 is implied.)
+.IP "\-i or \-\-ignore-case"
+Causes searches to ignore case; that is,
+uppercase and lowercase are considered identical.
+This option is ignored if any uppercase letters
+appear in the search pattern;
+in other words,
+if a pattern contains uppercase letters, then that search does not ignore case.
+.IP "\-I or \-\-IGNORE-CASE"
+Like \-i, but searches ignore case even if
+the pattern contains uppercase letters.
+.IP "\-j\fIn\fP or \-\-jump-target=\fIn\fP"
+Specifies a line on the screen where the "target" line
+is to be positioned.
+The target line is the line specified by any command to
+search for a pattern, jump to a line number,
+jump to a file percentage or jump to a tag.
+The screen line may be specified by a number: the top line on the screen
+is 1, the next is 2, and so on.
+The number may be negative to specify a line relative to the bottom
+of the screen: the bottom line on the screen is \-1, the second
+to the bottom is \-2, and so on.
+Alternately, the screen line may be specified as a fraction of the height
+of the screen, starting with a decimal point: .5 is in the middle of the
+screen, .3 is three tenths down from the first line, and so on.
+If the line is specified as a fraction, the actual line number
+is recalculated if the terminal window is resized, so that the
+target line remains at the specified fraction of the screen height.
+If any form of the \-j option is used,
+forward searches begin at the line immediately after the target line,
+and backward searches begin at the target line,
+unless changed by \-a or \-A.
+For example, if "\-j4" is used, the target line is the
+fourth line on the screen, so forward searches begin at the fifth line
+on the screen.
+.IP "\-J or \-\-status-column"
+Displays a status column at the left edge of the screen.
+The status column shows the lines that matched the current search.
+The status column is also used if the \-w or \-W option is in effect.
+.IP "\-k\fIfilename\fP or \-\-lesskey-file=\fIfilename\fP"
+Causes
+.I less
+to open and interpret the named file as a
+.I lesskey
+(1) file.
+Multiple \-k options may be specified.
+If the LESSKEY or LESSKEY_SYSTEM environment variable is set, or
+if a lesskey file is found in a standard place (see KEY BINDINGS),
+it is also used as a
+.I lesskey
+file.
+.IP "\-K or \-\-quit-on-intr"
+Causes
+.I less
+to exit immediately (with status 2)
+when an interrupt character (usually ^C) is typed.
+Normally, an interrupt character causes
+.I less
+to stop whatever it is doing and return to its command prompt.
+Note that use of this option makes it impossible to return to the
+command prompt from the "F" command.
+.IP "\-L or \-\-no-lessopen"
+Ignore the LESSOPEN environment variable
+(see the INPUT PREPROCESSOR section below).
+This option can be set from within \fIless\fP,
+but it will apply only to files opened subsequently, not to the
+file which is currently open.
+.IP "\-m or \-\-long-prompt"
+Causes
+.I less
+to prompt verbosely (like \fImore\fP),
+with the percent into the file.
+By default,
+.I less
+prompts with a colon.
+.IP "\-M or \-\-LONG-PROMPT"
+Causes
+.I less
+to prompt even more verbosely than
+.I more.
+.IP "\-n or \-\-line-numbers"
+Suppresses line numbers.
+The default (to use line numbers) may cause
+.I less
+to run more slowly in some cases, especially with a very large input file.
+Suppressing line numbers with the \-n option will avoid this problem.
+Using line numbers means: the line number will be displayed in the verbose
+prompt and in the = command,
+and the v command will pass the current line number to the editor
+(see also the discussion of LESSEDIT in PROMPTS below).
+.IP "\-N or \-\-LINE-NUMBERS"
+Causes a line number to be displayed at the beginning of
+each line in the display.
+.IP "\-o\fIfilename\fP or \-\-log-file=\fIfilename\fP"
+Causes
+.I less
+to copy its input to the named file as it is being viewed.
+This applies only when the input file is a pipe,
+not an ordinary file.
+If the file already exists,
+.I less
+will ask for confirmation before overwriting it.
+.IP "\-O\fIfilename\fP or \-\-LOG-FILE=\fIfilename\fP"
+The \-O option is like \-o, but it will overwrite an existing
+file without asking for confirmation.
+.sp
+If no log file has been specified,
+the \-o and \-O options can be used from within
+.I less
+to specify a log file.
+Without a file name, they will simply report the name of the log file.
+The "s" command is equivalent to specifying \-o from within
+.I less.
+.IP "\-p\fIpattern\fP or \-\-pattern=\fIpattern\fP"
+The \-p option on the command line is equivalent to
+specifying +/\fIpattern\fP;
+that is, it tells
+.I less
+to start at the first occurrence of \fIpattern\fP in the file.
+.IP "\-P\fIprompt\fP or \-\-prompt=\fIprompt\fP"
+Provides a way to tailor the three prompt
+styles to your own preference.
+This option would normally be put in the LESS environment
+variable, rather than being typed in with each
+.I less
+command.
+Such an option must either be the last option in the LESS variable,
+or be terminated by a dollar sign.
+-Ps followed by a string changes the default (short) prompt
+to that string.
+-Pm changes the medium (\-m) prompt.
+-PM changes the long (\-M) prompt.
+-Ph changes the prompt for the help screen.
+-P= changes the message printed by the = command.
+-Pw changes the message printed while waiting for data (in the F command).
+All prompt strings consist of a sequence of
+letters and special escape sequences.
+See the section on PROMPTS for more details.
+.IP "\-q or \-\-quiet or \-\-silent"
+Causes moderately "quiet" operation:
+the terminal bell is not rung
+if an attempt is made to scroll past the end of the file
+or before the beginning of the file.
+If the terminal has a "visual bell", it is used instead.
+The bell will be rung on certain other errors,
+such as typing an invalid character.
+The default is to ring the terminal bell in all such cases.
+.IP "\-Q or \-\-QUIET or \-\-SILENT"
+Causes totally "quiet" operation:
+the terminal bell is never rung.
+.IP "\-r or \-\-raw-control-chars"
+Causes "raw" control characters to be displayed.
+The default is to display control characters using the caret notation;
+for example, a control-A (octal 001) is displayed as "^A".
+Warning: when the \-r option is used,
+.I less
+cannot keep track of the actual appearance of the screen
+(since this depends on how the screen responds to
+each type of control character).
+Thus, various display problems may result,
+such as long lines being split in the wrong place.
+.IP "\-R or \-\-RAW-CONTROL-CHARS"
+Like \-r, but only ANSI "color" escape sequences are output in "raw" form.
+Unlike \-r, the screen appearance is maintained correctly in most cases.
+ANSI "color" escape sequences are sequences of the form:
+.sp
+ ESC [ ... m
+.sp
+where the "..." is zero or more color specification characters
+For the purpose of keeping track of screen appearance,
+ANSI color escape sequences are assumed to not move the cursor.
+You can make
+.I less
+think that characters other than "m" can end ANSI color escape sequences
+by setting the environment variable LESSANSIENDCHARS to the list of
+characters which can end a color escape sequence.
+And you can make
+.I less
+think that characters other than the standard ones may appear between
+the ESC and the m by setting the environment variable LESSANSIMIDCHARS
+to the list of characters which can appear.
+.IP "\-s or \-\-squeeze-blank-lines"
+Causes consecutive blank lines to be squeezed into a single blank line.
+This is useful when viewing
+.I nroff
+output.
+.IP "\-S or \-\-chop-long-lines"
+Causes lines longer than the screen width to be
+chopped (truncated) rather than wrapped.
+That is, the portion of a long line that does not fit in
+the screen width is not shown.
+The default is to wrap long lines; that is, display the remainder
+on the next line.
+.IP "\-t\fItag\fP or \-\-tag=\fItag\fP"
+The \-t option, followed immediately by a TAG,
+will edit the file containing that tag.
+For this to work, tag information must be available;
+for example, there may be a file in the current directory called "tags",
+which was previously built by
+.I ctags
+(1) or an equivalent command.
+If the environment variable LESSGLOBALTAGS is set, it is taken to be
+the name of a command compatible with
+.I global
+(1), and that command is executed to find the tag.
+(See http://www.gnu.org/software/global/global.html).
+The \-t option may also be specified from within
+.I less
+(using the \- command) as a way of examining a new file.
+The command ":t" is equivalent to specifying \-t from within
+.I less.
+.IP "\-T\fItagsfile\fP or \-\-tag-file=\fItagsfile\fP"
+Specifies a tags file to be used instead of "tags".
+.IP "\-u or \-\-underline-special"
+Causes backspaces and carriage returns to be treated as printable characters;
+that is, they are sent to the terminal when they appear in the input.
+.IP "\-U or \-\-UNDERLINE-SPECIAL"
+Causes backspaces, tabs and carriage returns to be
+treated as control characters;
+that is, they are handled as specified by the \-r option.
+.sp
+By default, if neither \-u nor \-U is given,
+backspaces which appear adjacent to an underscore character
+are treated specially:
+the underlined text is displayed
+using the terminal's hardware underlining capability.
+Also, backspaces which appear between two identical characters
+are treated specially:
+the overstruck text is printed
+using the terminal's hardware boldface capability.
+Other backspaces are deleted, along with the preceding character.
+Carriage returns immediately followed by a newline are deleted.
+Other carriage returns are handled as specified by the \-r option.
+Text which is overstruck or underlined can be searched for
+if neither \-u nor \-U is in effect.
+.IP "\-V or \-\-version"
+Displays the version number of
+.I less.
+.IP "\-w or \-\-hilite-unread"
+Temporarily highlights the first "new" line after a forward movement
+of a full page.
+The first "new" line is the line immediately following the line previously
+at the bottom of the screen.
+Also highlights the target line after a g or p command.
+The highlight is removed at the next command which causes movement.
+The entire line is highlighted, unless the \-J option is in effect,
+in which case only the status column is highlighted.
+.IP "\-W or \-\-HILITE-UNREAD"
+Like \-w, but temporarily highlights the first new line after any
+forward movement command larger than one line.
+.IP "\-x\fIn\fP,... or \-\-tabs=\fIn\fP,..."
+Sets tab stops.
+If only one \fIn\fP is specified, tab stops are set at multiples of \fIn\fP.
+If multiple values separated by commas are specified, tab stops
+are set at those positions, and then continue with the same spacing as the
+last two.
+For example, \fI-x9,17\fP will set tabs at positions 9, 17, 25, 33, etc.
+The default for \fIn\fP is 8.
+.IP "\-X or \-\-no-init"
+Disables sending the termcap initialization and deinitialization strings
+to the terminal.
+This is sometimes desirable if the deinitialization string does
+something unnecessary, like clearing the screen.
+.IP "\-y\fIn\fP or \-\-max-forw-scroll=\fIn\fP"
+Specifies a maximum number of lines to scroll forward.
+If it is necessary to scroll forward more than \fIn\fP lines,
+the screen is repainted instead.
+The \-c or \-C option may be used to repaint from the top of
+the screen if desired.
+By default, any forward movement causes scrolling.
+.IP "\-[z]\fIn\fP or \-\-window=\fIn\fP"
+Changes the default scrolling window size to \fIn\fP lines.
+The default is one screenful.
+The z and w commands can also be used to change the window size.
+The "z" may be omitted for compatibility with some versions of
+.I more.
+If the number
+.I n
+is negative, it indicates
+.I n
+lines less than the current screen size.
+For example, if the screen is 24 lines, \fI\-z-4\fP sets the
+scrolling window to 20 lines. If the screen is resized to 40 lines,
+the scrolling window automatically changes to 36 lines.
+.IP "\-\fI\(dqcc\fP\ or\ \-\-quotes=\fIcc\fP"
+Changes the filename quoting character.
+This may be necessary if you are trying to name a file
+which contains both spaces and quote characters.
+Followed by a single character, this changes the quote character to that
+character.
+Filenames containing a space should then be surrounded by that character
+rather than by double quotes.
+Followed by two characters, changes the open quote to the first character,
+and the close quote to the second character.
+Filenames containing a space should then be preceded by the open quote
+character and followed by the close quote character.
+Note that even after the quote characters are changed, this option
+remains \-" (a dash followed by a double quote).
+.IP "\-~ or \-\-tilde"
+Normally lines after end of file are displayed as a single tilde (~).
+This option causes lines after end of file to be displayed as blank lines.
+.IP "\-# or \-\-shift"
+Specifies the default number of positions to scroll horizontally
+in the RIGHTARROW and LEFTARROW commands.
+If the number specified is zero, it sets the default number of
+positions to one half of the screen width.
+Alternately, the number may be specified as a fraction of the width
+of the screen, starting with a decimal point: .5 is half of the
+screen width, .3 is three tenths of the screen width, and so on.
+If the number is specified as a fraction, the actual number of
+scroll positions is recalculated if the terminal window is resized,
+so that the actual scroll remains at the specified fraction
+of the screen width.
+.IP "\-\-follow-name"
+Normally, if the input file is renamed while an F command is executing,
+.I less
+will continue to display the contents of the original file despite
+its name change.
+If \-\-follow-name is specified, during an F command
+.I less
+will periodically attempt to reopen the file by name.
+If the reopen succeeds and the file is a different file from the original
+(which means that a new file has been created
+with the same name as the original (now renamed) file),
+.I less
+will display the contents of that new file.
+.IP "\-\-no-keypad"
+Disables sending the keypad initialization and deinitialization strings
+to the terminal.
+This is sometimes useful if the keypad strings make the numeric
+keypad behave in an undesirable manner.
+.IP "\-\-use-backslash"
+This option changes the interpretations of options which follow this one.
+After the \-\-use-backslash option, any backslash in an option string is
+removed and the following character is taken literally.
+This allows a dollar sign to be included in option strings.
+.IP \-\-
+A command line argument of "\-\-" marks the end of option arguments.
+Any arguments following this are interpreted as filenames.
+This can be useful when viewing a file whose name begins with a "\-" or "+".
+.IP +
+If a command line option begins with \fB+\fP,
+the remainder of that option is taken to be an initial command to
+.I less.
+For example, +G tells
+.I less
+to start at the end of the file rather than the beginning,
+and +/xyz tells it to start at the first occurrence of "xyz" in the file.
+As a special case, +<number> acts like +<number>g;
+that is, it starts the display at the specified line number
+(however, see the caveat under the "g" command above).
+If the option starts with ++, the initial command applies to
+every file being viewed, not just the first one.
+The + command described previously
+may also be used to set (or change) an initial command for every file.
+
+.SH "LINE EDITING"
+When entering command line at the bottom of the screen
+(for example, a filename for the :e command,
+or the pattern for a search command),
+certain keys can be used to manipulate the command line.
+Most commands have an alternate form in [ brackets ] which can be used if
+a key does not exist on a particular keyboard.
+(Note that the forms beginning with ESC do not work
+in some MS-DOS and Windows systems because ESC is the line erase character.)
+Any of these special keys may be entered literally by preceding
+it with the "literal" character, either ^V or ^A.
+A backslash itself may also be entered literally by entering two backslashes.
+.IP "LEFTARROW [ ESC-h ]"
+Move the cursor one space to the left.
+.IP "RIGHTARROW [ ESC-l ]"
+Move the cursor one space to the right.
+.IP "^LEFTARROW [ ESC-b or ESC-LEFTARROW ]"
+(That is, CONTROL and LEFTARROW simultaneously.)
+Move the cursor one word to the left.
+.IP "^RIGHTARROW [ ESC-w or ESC-RIGHTARROW ]"
+(That is, CONTROL and RIGHTARROW simultaneously.)
+Move the cursor one word to the right.
+.IP "HOME [ ESC-0 ]"
+Move the cursor to the beginning of the line.
+.IP "END [ ESC-$ ]"
+Move the cursor to the end of the line.
+.IP "BACKSPACE"
+Delete the character to the left of the cursor,
+or cancel the command if the command line is empty.
+.IP "DELETE or [ ESC-x ]"
+Delete the character under the cursor.
+.IP "^BACKSPACE [ ESC-BACKSPACE ]"
+(That is, CONTROL and BACKSPACE simultaneously.)
+Delete the word to the left of the cursor.
+.IP "^DELETE [ ESC-X or ESC-DELETE ]"
+(That is, CONTROL and DELETE simultaneously.)
+Delete the word under the cursor.
+.IP "UPARROW [ ESC-k ]"
+Retrieve the previous command line.
+If you first enter some text and then press UPARROW,
+it will retrieve the previous command which begins with that text.
+.IP "DOWNARROW [ ESC-j ]"
+Retrieve the next command line.
+If you first enter some text and then press DOWNARROW,
+it will retrieve the next command which begins with that text.
+.IP "TAB"
+Complete the partial filename to the left of the cursor.
+If it matches more than one filename, the first match
+is entered into the command line.
+Repeated TABs will cycle thru the other matching filenames.
+If the completed filename is a directory, a "/" is appended to the filename.
+(On MS-DOS systems, a "\e" is appended.)
+The environment variable LESSSEPARATOR can be used to specify a
+different character to append to a directory name.
+.IP "BACKTAB [ ESC-TAB ]"
+Like, TAB, but cycles in the reverse direction thru the matching filenames.
+.IP "^L"
+Complete the partial filename to the left of the cursor.
+If it matches more than one filename, all matches are entered into
+the command line (if they fit).
+.IP "^U (Unix and OS/2) or ESC (MS-DOS)"
+Delete the entire command line,
+or cancel the command if the command line is empty.
+If you have changed your line-kill character in Unix to something
+other than ^U, that character is used instead of ^U.
+.IP "^G"
+Delete the entire command line and return to the main prompt.
+
+.SH "KEY BINDINGS"
+You may define your own
+.I less
+commands by using the program
+.I lesskey
+(1)
+to create a lesskey file.
+This file specifies a set of command keys and an action
+associated with each key.
+You may also use
+.I lesskey
+to change the line-editing keys (see LINE EDITING),
+and to set environment variables.
+If the environment variable LESSKEY is set,
+.I less
+uses that as the name of the lesskey file.
+Otherwise,
+.I less
+looks in a standard place for the lesskey file:
+On Unix systems,
+.I less
+looks for a lesskey file called "$HOME/.less".
+On MS-DOS and Windows systems,
+.I less
+looks for a lesskey file called "$HOME/_less", and if it is not found there,
+then looks for a lesskey file called "_less" in any directory specified
+in the PATH environment variable.
+On OS/2 systems,
+.I less
+looks for a lesskey file called "$HOME/less.ini", and if it is not found,
+then looks for a lesskey file called "less.ini" in any directory specified
+in the INIT environment variable, and if it not found there,
+then looks for a lesskey file called "less.ini" in any directory specified
+in the PATH environment variable.
+See the
+.I lesskey
+manual page for more details.
+.P
+A system-wide lesskey file may also be set up to provide key bindings.
+If a key is defined in both a local lesskey file and in the
+system-wide file, key bindings in the local file take precedence over
+those in the system-wide file.
+If the environment variable LESSKEY_SYSTEM is set,
+.I less
+uses that as the name of the system-wide lesskey file.
+Otherwise,
+.I less
+looks in a standard place for the system-wide lesskey file:
+On Unix systems, the system-wide lesskey file is /usr/local/etc/sysless.
+(However, if
+.I less
+was built with a different sysconf directory than /usr/local/etc,
+that directory is where the sysless file is found.)
+On MS-DOS and Windows systems, the system-wide lesskey file is c:\e_sysless.
+On OS/2 systems, the system-wide lesskey file is c:\esysless.ini.
+
+.SH "INPUT PREPROCESSOR"
+You may define an "input preprocessor" for
+.I less.
+Before
+.I less
+opens a file, it first gives your input preprocessor a chance to modify the
+way the contents of the file are displayed.
+An input preprocessor is simply an executable program (or shell script),
+which writes the contents of the file to a different file,
+called the replacement file.
+The contents of the replacement file are then displayed
+in place of the contents of the original file.
+However, it will appear to the user as if the original file is opened;
+that is,
+.I less
+will display the original filename as the name of the current file.
+.PP
+An input preprocessor receives one command line argument, the original filename,
+as entered by the user.
+It should create the replacement file, and when finished,
+print the name of the replacement file to its standard output.
+If the input preprocessor does not output a replacement filename,
+.I less
+uses the original file, as normal.
+The input preprocessor is not called when viewing standard input.
+To set up an input preprocessor, set the LESSOPEN environment variable
+to a command line which will invoke your input preprocessor.
+This command line should include one occurrence of the string "%s",
+which will be replaced by the filename
+when the input preprocessor command is invoked.
+.PP
+When
+.I less
+closes a file opened in such a way, it will call another program,
+called the input postprocessor,
+which may perform any desired clean-up action (such as deleting the
+replacement file created by LESSOPEN).
+This program receives two command line arguments, the original filename
+as entered by the user, and the name of the replacement file.
+To set up an input postprocessor, set the LESSCLOSE environment variable
+to a command line which will invoke your input postprocessor.
+It may include two occurrences of the string "%s";
+the first is replaced with the original name of the file and
+the second with the name of the replacement file,
+which was output by LESSOPEN.
+.PP
+For example, on many Unix systems, these two scripts will allow you
+to keep files in compressed format, but still let
+.I less
+view them directly:
+.PP
+lessopen.sh:
+.br
+ #! /bin/sh
+.br
+ case "$1" in
+.br
+ *.Z) uncompress -\c $1 >/tmp/less.$$ 2>/dev/null
+.br
+ if [ \-s /tmp/less.$$ ]; then
+.br
+ echo /tmp/less.$$
+.br
+ else
+.br
+ rm \-f /tmp/less.$$
+.br
+ fi
+.br
+ ;;
+.br
+ esac
+.PP
+lessclose.sh:
+.br
+ #! /bin/sh
+.br
+ rm $2
+.PP
+To use these scripts, put them both where they can be executed and
+set LESSOPEN="lessopen.sh\ %s", and
+LESSCLOSE="lessclose.sh\ %s\ %s".
+More complex LESSOPEN and LESSCLOSE scripts may be written
+to accept other types of compressed files, and so on.
+.PP
+It is also possible to set up an input preprocessor to
+pipe the file data directly to
+.I less,
+rather than putting the data into a replacement file.
+This avoids the need to decompress the entire file before
+starting to view it.
+An input preprocessor that works this way is called an input pipe.
+An input pipe, instead of writing the name of a replacement file on
+its standard output,
+writes the entire contents of the replacement file on its standard output.
+If the input pipe does not write any characters on its standard output,
+then there is no replacement file and
+.I less
+uses the original file, as normal.
+To use an input pipe,
+make the first character in the LESSOPEN environment variable a
+vertical bar (|) to signify that the input preprocessor is an input pipe.
+.PP
+For example, on many Unix systems, this script will work like the
+previous example scripts:
+.PP
+lesspipe.sh:
+.br
+ #! /bin/sh
+.br
+ case "$1" in
+.br
+ *.Z) uncompress \-c $1 2>/dev/null
+.br
+ *) exit 1
+.br
+ ;;
+.br
+ esac
+.br
+ exit $?
+.br
+.PP
+To use this script, put it where it can be executed and set
+LESSOPEN="|lesspipe.sh %s".
+.PP
+Note that a preprocessor cannot output an empty file, since that
+is interpreted as meaning there is no replacement, and
+the original file is used.
+To avoid this, if LESSOPEN starts with two vertical bars,
+the exit status of the script becomes meaningful.
+If the exit status is zero, the output is considered to be
+replacement text, even if it empty.
+If the exit status is nonzero, any output is ignored and the
+original file is used.
+For compatibility with previous versions of
+.I less,
+if LESSOPEN starts with only one vertical bar, the exit status
+of the preprocessor is ignored.
+.PP
+When an input pipe is used, a LESSCLOSE postprocessor can be used,
+but it is usually not necessary since there is no replacement file
+to clean up.
+In this case, the replacement file name passed to the LESSCLOSE
+postprocessor is "\-".
+.PP
+For compatibility with previous versions of
+.I less,
+the input preprocessor or pipe is not used if
+.I less
+is viewing standard input.
+However, if the first character of LESSOPEN is a dash (\-),
+the input preprocessor is used on standard input as well as other files.
+In this case, the dash is not considered to be part of
+the preprocessor command.
+If standard input is being viewed, the input preprocessor is passed
+a file name consisting of a single dash.
+Similarly, if the first two characters of LESSOPEN are vertical bar and dash
+(|\-) or two vertical bars and a dash (||\-),
+the input pipe is used on standard input as well as other files.
+Again, in this case the dash is not considered to be part of
+the input pipe command.
+
+.SH "NATIONAL CHARACTER SETS"
+There are three types of characters in the input file:
+.IP "normal characters"
+can be displayed directly to the screen.
+.IP "control characters"
+should not be displayed directly, but are expected to be found
+in ordinary text files (such as backspace and tab).
+.IP "binary characters"
+should not be displayed directly and are not expected to be found
+in text files.
+.PP
+A "character set" is simply a description of which characters are to
+be considered normal, control, and binary.
+The LESSCHARSET environment variable may be used to select a character set.
+Possible values for LESSCHARSET are:
+.IP ascii
+BS, TAB, NL, CR, and formfeed are control characters,
+all chars with values between 32 and 126 are normal,
+and all others are binary.
+.IP iso8859
+Selects an ISO 8859 character set.
+This is the same as ASCII, except characters between 160 and 255 are
+treated as normal characters.
+.IP latin1
+Same as iso8859.
+.IP latin9
+Same as iso8859.
+.IP dos
+Selects a character set appropriate for MS-DOS.
+.IP ebcdic
+Selects an EBCDIC character set.
+.IP IBM-1047
+Selects an EBCDIC character set used by OS/390 Unix Services.
+This is the EBCDIC analogue of latin1. You get similar results
+by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US
+in your environment.
+.IP koi8-r
+Selects a Russian character set.
+.IP next
+Selects a character set appropriate for NeXT computers.
+.IP utf-8
+Selects the UTF-8 encoding of the ISO 10646 character set.
+UTF-8 is special in that it supports multi-byte characters in the input file.
+It is the only character set that supports multi-byte characters.
+.IP windows
+Selects a character set appropriate for Microsoft Windows (cp 1251).
+.PP
+In rare cases, it may be desired to tailor
+.I less
+to use a character set other than the ones definable by LESSCHARSET.
+In this case, the environment variable LESSCHARDEF can be used
+to define a character set.
+It should be set to a string where each character in the string represents
+one character in the character set.
+The character "." is used for a normal character, "c" for control,
+and "b" for binary.
+A decimal number may be used for repetition.
+For example, "bccc4b." would mean character 0 is binary,
+1, 2 and 3 are control, 4, 5, 6 and 7 are binary, and 8 is normal.
+All characters after the last are taken to be the same as the last,
+so characters 9 through 255 would be normal.
+(This is an example, and does not necessarily
+represent any real character set.)
+.PP
+This table shows the value of LESSCHARDEF which is equivalent
+to each of the possible values for LESSCHARSET:
+.sp
+ ascii\ 8bcccbcc18b95.b
+.br
+ dos\ \ \ 8bcccbcc12bc5b95.b.
+.br
+ ebcdic 5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
+.br
+ \ \ \ \ \ \ 9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
+.br
+ IBM-1047 4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
+.br
+ \ \ \ \ \ \ 191.b
+.br
+ iso8859 8bcccbcc18b95.33b.
+.br
+ koi8-r 8bcccbcc18b95.b128.
+.br
+ latin1 8bcccbcc18b95.33b.
+.br
+ next\ \ 8bcccbcc18b95.bb125.bb
+.PP
+If neither LESSCHARSET nor LESSCHARDEF is set,
+but any of the strings "UTF-8", "UTF8", "utf-8" or "utf8"
+is found in the LC_ALL, LC_CTYPE or LANG
+environment variables, then the default character set is utf-8.
+.PP
+If that string is not found, but your system supports the
+.I setlocale
+interface,
+.I less
+will use setlocale to determine the character set.
+setlocale is controlled by setting the LANG or LC_CTYPE environment
+variables.
+.PP
+Finally, if the
+.I setlocale
+interface is also not available, the default character set is latin1.
+.PP
+Control and binary characters are displayed in standout (reverse video).
+Each such character is displayed in caret notation if possible
+(e.g. ^A for control-A). Caret notation is used only if
+inverting the 0100 bit results in a normal printable character.
+Otherwise, the character is displayed as a hex number in angle brackets.
+This format can be changed by
+setting the LESSBINFMT environment variable.
+LESSBINFMT may begin with a "*" and one character to select
+the display attribute:
+"*k" is blinking, "*d" is bold, "*u" is underlined, "*s" is standout,
+and "*n" is normal.
+If LESSBINFMT does not begin with a "*", normal attribute is assumed.
+The remainder of LESSBINFMT is a string which may include one
+printf-style escape sequence (a % followed by x, X, o, d, etc.).
+For example, if LESSBINFMT is "*u[%x]", binary characters
+are displayed in underlined hexadecimal surrounded by brackets.
+The default if no LESSBINFMT is specified is "*s<%02X>".
+Warning: the result of expanding the character via LESSBINFMT must
+be less than 31 characters.
+.PP
+When the character set is utf-8, the LESSUTFBINFMT environment variable
+acts similarly to LESSBINFMT but it applies to Unicode code points
+that were successfully decoded but are unsuitable for display (e.g.,
+unassigned code points).
+Its default value is "<U+%04lX>".
+Note that LESSUTFBINFMT and LESSBINFMT share their display attribute
+setting ("*x") so specifying one will affect both;
+LESSUTFBINFMT is read after LESSBINFMT so its setting, if any,
+will have priority.
+Problematic octets in a UTF-8 file (octets of a truncated sequence,
+octets of a complete but non-shortest form sequence, illegal octets,
+and stray trailing octets)
+are displayed individually using LESSBINFMT so as to facilitate diagnostic
+of how the UTF-8 file is ill-formed.
+
+.SH "PROMPTS"
+The \-P option allows you to tailor the prompt to your preference.
+The string given to the \-P option replaces the specified prompt string.
+Certain characters in the string are interpreted specially.
+The prompt mechanism is rather complicated to provide flexibility,
+but the ordinary user need not understand the details of constructing
+personalized prompt strings.
+.sp
+A percent sign followed by a single character is expanded
+according to what the following character is:
+.IP "%b\fIX\fP"
+Replaced by the byte offset into the current input file.
+The b is followed by a single character (shown as \fIX\fP above)
+which specifies the line whose byte offset is to be used.
+If the character is a "t", the byte offset of the top line in the
+display is used,
+an "m" means use the middle line,
+a "b" means use the bottom line,
+a "B" means use the line just after the bottom line,
+and a "j" means use the "target" line, as specified by the \-j option.
+.IP "%B"
+Replaced by the size of the current input file.
+.IP "%c"
+Replaced by the column number of the text appearing in the first
+column of the screen.
+.IP "%d\fIX\fP"
+Replaced by the page number of a line in the input file.
+The line to be used is determined by the \fIX\fP, as with the %b option.
+.IP "%D"
+Replaced by the number of pages in the input file,
+or equivalently, the page number of the last line in the input file.
+.IP "%E"
+Replaced by the name of the editor (from the VISUAL environment variable,
+or the EDITOR environment variable if VISUAL is not defined).
+See the discussion of the LESSEDIT feature below.
+.IP "%f"
+Replaced by the name of the current input file.
+.IP "%F"
+Replaced by the last component of the name of the current input file.
+.IP "%i"
+Replaced by the index of the current file in the list of
+input files.
+.IP "%l\fIX\fP"
+Replaced by the line number of a line in the input file.
+The line to be used is determined by the \fIX\fP, as with the %b option.
+.IP "%L"
+Replaced by the line number of the last line in the input file.
+.IP "%m"
+Replaced by the total number of input files.
+.IP "%p\fIX\fP"
+Replaced by the percent into the current input file, based on byte offsets.
+The line used is determined by the \fIX\fP as with the %b option.
+.IP "%P\fIX\fP"
+Replaced by the percent into the current input file, based on line numbers.
+The line used is determined by the \fIX\fP as with the %b option.
+.IP "%s"
+Same as %B.
+.IP "%t"
+Causes any trailing spaces to be removed.
+Usually used at the end of the string, but may appear anywhere.
+.IP "%x"
+Replaced by the name of the next input file in the list.
+.PP
+If any item is unknown (for example, the file size if input
+is a pipe), a question mark is printed instead.
+.PP
+The format of the prompt string can be changed
+depending on certain conditions.
+A question mark followed by a single character acts like an "IF":
+depending on the following character, a condition is evaluated.
+If the condition is true, any characters following the question mark
+and condition character, up to a period, are included in the prompt.
+If the condition is false, such characters are not included.
+A colon appearing between the question mark and the
+period can be used to establish an "ELSE": any characters between
+the colon and the period are included in the string if and only if
+the IF condition is false.
+Condition characters (which follow a question mark) may be:
+.IP "?a"
+True if any characters have been included in the prompt so far.
+.IP "?b\fIX\fP"
+True if the byte offset of the specified line is known.
+.IP "?B"
+True if the size of current input file is known.
+.IP "?c"
+True if the text is horizontally shifted (%c is not zero).
+.IP "?d\fIX\fP"
+True if the page number of the specified line is known.
+.IP "?e"
+True if at end-of-file.
+.IP "?f"
+True if there is an input filename
+(that is, if input is not a pipe).
+.IP "?l\fIX\fP"
+True if the line number of the specified line is known.
+.IP "?L"
+True if the line number of the last line in the file is known.
+.IP "?m"
+True if there is more than one input file.
+.IP "?n"
+True if this is the first prompt in a new input file.
+.IP "?p\fIX\fP"
+True if the percent into the current input file, based on byte offsets,
+of the specified line is known.
+.IP "?P\fIX\fP"
+True if the percent into the current input file, based on line numbers,
+of the specified line is known.
+.IP "?s"
+Same as "?B".
+.IP "?x"
+True if there is a next input file
+(that is, if the current input file is not the last one).
+.PP
+Any characters other than the special ones
+(question mark, colon, period, percent, and backslash)
+become literally part of the prompt.
+Any of the special characters may be included in the prompt literally
+by preceding it with a backslash.
+.PP
+Some examples:
+.sp
+?f%f:Standard input.
+.sp
+This prompt prints the filename, if known;
+otherwise the string "Standard input".
+.sp
+?f%f .?ltLine %lt:?pt%pt\e%:?btByte %bt:-...
+.sp
+This prompt would print the filename, if known.
+The filename is followed by the line number, if known,
+otherwise the percent if known, otherwise the byte offset if known.
+Otherwise, a dash is printed.
+Notice how each question mark has a matching period,
+and how the % after the %pt
+is included literally by escaping it with a backslash.
+.sp
+?n?f%f\ .?m(file\ %i\ of\ %m)\ ..?e(END)\ ?x-\ Next\e:\ %x..%t
+.sp
+This prints the filename if this is the first prompt in a file,
+followed by the "file N of N" message if there is more
+than one input file.
+Then, if we are at end-of-file, the string "(END)" is printed
+followed by the name of the next file, if there is one.
+Finally, any trailing spaces are truncated.
+This is the default prompt.
+For reference, here are the defaults for
+the other two prompts (\-m and \-M respectively).
+Each is broken into two lines here for readability only.
+.nf
+.sp
+?n?f%f\ .?m(file\ %i\ of\ %m)\ ..?e(END)\ ?x-\ Next\e:\ %x.:
+ ?pB%pB\e%:byte\ %bB?s/%s...%t
+.sp
+?f%f\ .?n?m(file\ %i\ of\ %m)\ ..?ltlines\ %lt-%lb?L/%L.\ :
+ byte\ %bB?s/%s.\ .?e(END)\ ?x-\ Next\e:\ %x.:?pB%pB\e%..%t
+.sp
+.fi
+And here is the default message produced by the = command:
+.nf
+.sp
+?f%f\ .?m(file\ %i\ of\ %m)\ .?ltlines\ %lt-%lb?L/%L.\ .
+ byte\ %bB?s/%s.\ ?e(END)\ :?pB%pB\e%..%t
+.fi
+.PP
+The prompt expansion features are also used for another purpose:
+if an environment variable LESSEDIT is defined, it is used
+as the command to be executed when the v command is invoked.
+The LESSEDIT string is expanded in the same way as the prompt strings.
+The default value for LESSEDIT is:
+.nf
+.sp
+ %E\ ?lm+%lm.\ %f
+.sp
+.fi
+Note that this expands to the editor name, followed by a + and the
+line number, followed by the file name.
+If your editor does not accept the "+linenumber" syntax, or has other
+differences in invocation syntax, the LESSEDIT variable can be
+changed to modify this default.
+
+.SH SECURITY
+When the environment variable LESSSECURE is set to 1,
+.I less
+runs in a "secure" mode.
+This means these features are disabled:
+.RS
+.IP "!"
+the shell command
+.IP "|"
+the pipe command
+.IP ":e"
+the examine command.
+.IP "v"
+the editing command
+.IP "s \-o"
+log files
+.IP "\-k"
+use of lesskey files
+.IP "\-t"
+use of tags files
+.IP " "
+metacharacters in filenames, such as *
+.IP " "
+filename completion (TAB, ^L)
+.RE
+.PP
+Less can also be compiled to be permanently in "secure" mode.
+
+.SH "COMPATIBILITY WITH MORE"
+If the environment variable LESS_IS_MORE is set to 1,
+or if the program is invoked via a file link named "more",
+.I less
+behaves (mostly) in conformance with the POSIX "more" command specification.
+In this mode, less behaves differently in these ways:
+.PP
+The \-e option works differently.
+If the \-e option is not set,
+.I less
+behaves as if the \-E option were set.
+If the \-e option is set,
+.I less
+behaves as if the \-e and \-F options were set.
+.PP
+The \-m option works differently.
+If the \-m option is not set, the medium prompt is used,
+and it is prefixed with the string "--More--".
+If the \-m option is set, the short prompt is used.
+.PP
+The \-n option acts like the \-z option.
+The normal behavior of the \-n option is unavailable in this mode.
+.PP
+The parameter to the \-p option is taken to be a
+.I less
+command rather than a search pattern.
+.PP
+The LESS environment variable is ignored,
+and the MORE environment variable is used in its place.
+
+.SH "ENVIRONMENT VARIABLES"
+Environment variables may be specified either in the system environment
+as usual, or in a
+.I lesskey
+(1) file.
+If environment variables are defined in more than one place,
+variables defined in a local lesskey file take precedence over
+variables defined in the system environment, which take precedence
+over variables defined in the system-wide lesskey file.
+.IP COLUMNS
+Sets the number of columns on the screen.
+Takes precedence over the number of columns specified by the TERM variable.
+(But if you have a windowing system which supports TIOCGWINSZ or WIOCGETD,
+the window system's idea of the screen size takes precedence over the
+LINES and COLUMNS environment variables.)
+.IP EDITOR
+The name of the editor (used for the v command).
+.IP HOME
+Name of the user's home directory
+(used to find a lesskey file on Unix and OS/2 systems).
+.IP "HOMEDRIVE, HOMEPATH"
+Concatenation of the HOMEDRIVE and HOMEPATH environment variables is
+the name of the user's home directory if the HOME variable is not set
+(only in the Windows version).
+.IP INIT
+Name of the user's init directory (used to find a lesskey file on OS/2 systems).
+.IP LANG
+Language for determining the character set.
+.IP LC_CTYPE
+Language for determining the character set.

+.IP LESSCHARSET
+Selects a predefined character set.
+.IP LESSCLOSE
+Command line to invoke the (optional) input-postprocessor.
+.IP LESSECHO
+Name of the lessecho program (default "lessecho").
+The lessecho program is needed to expand metacharacters, such as * and ?,
+in filenames on Unix systems.
+.IP LESSEDIT
+Editor prototype string (used for the v command).
+See discussion under PROMPTS.
+.IP LESSGLOBALTAGS
+Name of the command used by the \-t option to find global tags.
+Normally should be set to "global" if your system has the
+.I global
+(1) command. If not set, global tags are not used.
+.IP LESSHISTFILE
+Name of the history file used to remember search commands and
+shell commands between invocations of
+.I less.
+If set to "\-" or "/dev/null", a history file is not used.
+The default is "$HOME/.lesshst" on Unix systems, "$HOME/_lesshst" on
+DOS and Windows systems, or "$HOME/lesshst.ini" or "$INIT/lesshst.ini"
+on OS/2 systems.
+.IP LESSHISTSIZE
+The maximum number of commands to save in the history file.
+The default is 100.
+.IP LESSKEY
+Name of the default lesskey(1) file.
+.IP LESSKEY_SYSTEM
+Name of the default system-wide lesskey(1) file.
+.IP LESSMETACHARS
+List of characters which are considered "metacharacters" by the shell.

+Sets the number of lines on the screen.
+Takes precedence over the number of lines specified by the TERM variable.
+(But if you have a windowing system which supports TIOCGWINSZ or WIOCGETD,

- * 4. A backslash followed by b, e, n, r or t
- * to specify \b, ESC, \n, \r or \t, respectively.
- * 5. Any character (other than those mentioned above) preceded
- * by a \ to specify the character itself (characters which
- * must be preceded by \ include ^, \, and whitespace.
- * "action" is the name of a "less" action, from the table below.
- * "chars" is an optional sequence of characters which is treated
- * as keyboard input after the command is executed.
- *
- * Blank lines and lines which start with # are ignored,
- * except for the special control lines:
- * #command Signals the beginning of the command
- * keys section.
- * #line-edit Signals the beginning of the line-editing
- * keys section.
- * #env Signals the beginning of the environment
- * variable section.
- * #stop Stops command parsing in less;

- *
- * The output file is a non-ascii file, consisting of a header,
- * one or more sections, and a trailer.
- * Each section begins with a section header, a section length word
- * and the section data. Normally there are three sections:
- * CMD_SECTION Definition of command keys.
- * EDIT_SECTION Definition of editing keys.
- * END_SECTION A special section header, with no
- * length word or section data.
- *
- * Section data consists of zero or more byte sequences of the form:
- * string <0> <action>
- * or
- * string <0> <action|A_EXTRA> chars <0>
- *
- * "string" is the command string.
- * "<0>" is one null byte.
- * "<action>" is one byte containing the action code (the A_xxx value).
- * If action is ORed with A_EXTRA, the action byte is followed
- * by the null-terminated "chars" string.

+ * 5. Any character (other than those mentioned above) preceded
+ * by a \ to specify the character itself (characters which
+ * must be preceded by \ include ^, \, and whitespace.
+ * "action" is the name of a "less" action, from the table below.
+ * "chars" is an optional sequence of characters which is treated

+ * Each section begins with a section header, a section length word
+ * and the section data. Normally there are three sections:
+ * CMD_SECTION Definition of command keys.
+ * EDIT_SECTION Definition of editing keys.
+ * END_SECTION A special section header, with no
+ * length word or section data.

+ * Section data consists of zero or more byte sequences of the form:

+ *
+ * "string" is the command string.
+ * "<0>" is one null byte.
+ * "<action>" is one byte containing the action code (the A_xxx value).

- lesskey - specify key bindings for less
-
-[1mSYNOPSIS[0m
- [1mlesskey [-o output] [--] [input][0m
- [1mlesskey [--output=output] [--] [input][0m
- [1mlesskey -V[0m
- [1mlesskey --version[0m
-
-[1mDESCRIPTION[0m
- [4mLesskey[24m is used to specify a set of key bindings to be used by [4mless.[0m
- The input file is a text file which describes the key bindings, If the
- input file is "-", standard input is read. If no input file is speci-
- fied, a standard filename is used as the name of the input file, which
- depends on the system being used: On Unix systems, $HOME/.lesskey is
- used; on MS-DOS systems, $HOME/_lesskey is used; and on OS/2 systems
- $HOME/lesskey.ini is used, or $INIT/lesskey.ini if $HOME is undefined.
- The output file is a binary file which is used by [4mless.[24m If no output
- file is specified, and the environment variable LESSKEY is set, the
- value of LESSKEY is used as the name of the output file. Otherwise, a
- standard filename is used as the name of the output file, which depends
- on the system being used: On Unix and OS-9 systems, $HOME/.less is
- used; on MS-DOS systems, $HOME/_less is used; and on OS/2 systems,
- $HOME/less.ini is used, or $INIT/less.ini if $HOME is undefined. If
- the output file already exists, [4mlesskey[24m will overwrite it.
-
- The -V or --version option causes [4mlesskey[24m to print its version number
- and immediately exit. If -V or --version is present, other options and
- arguments are ignored.
-
- The input file consists of one or more [4msections.[24m Each section starts
- with a line that identifies the type of section. Possible sections
- are:
-
- #command
- Defines new command keys.
-
- #line-edit
- Defines new line-editing keys.
-
- #env Defines environment variables.
-
- Blank lines and lines which start with a pound sign (#) are ignored,
- except for the special section header lines.
-
-
-[1mCOMMAND SECTION[0m
- The command section begins with the line
-
- #command
-
- If the command section is the first section in the file, this line may
- be omitted. The command section consists of lines of the form:
-
- [4mstring[24m <whitespace> [4maction[24m [extra-string] <newline>
-
- Whitespace is any sequence of one or more spaces and/or tabs. The
- [4mstring[24m is the command key(s) which invoke the action. The [4mstring[24m may
- be a single command key, or a sequence of up to 15 keys. The [4maction[24m is
- the name of the less action, from the list below. The characters in
- the [4mstring[24m may appear literally, or be prefixed by a caret to indicate
- a control key. A backslash followed by one to three octal digits may
- be used to specify a character by its octal value. A backslash fol-
- lowed by certain characters specifies input characters as follows:
-
- \b BACKSPACE
-
- \e ESCAPE
-
- \n NEWLINE
-
- \r RETURN
-
- \t TAB
-
- \ku UP ARROW
-
- \kd DOWN ARROW
-
- \kr RIGHT ARROW
-
- \kl LEFT ARROW
-
- \kU PAGE UP
-
- \kD PAGE DOWN
-
- \kh HOME
-
- \ke END
-
- \kx DELETE
-
- A backslash followed by any other character indicates that character is
- to be taken literally. Characters which must be preceded by backslash
- include caret, space, tab and the backslash itself.
-
- An action may be followed by an "extra" string. When such a command is
- entered while running [4mless,[24m the action is performed, and then the extra
- string is parsed, just as if it were typed in to [4mless.[24m This feature
- can be used in certain cases to extend the functionality of a command.
- For example, see the "{" and ":t" commands in the example below. The
- extra string has a special meaning for the "quit" action: when [4mless[0m
- quits, first character of the extra string is used as its exit status.
-

-[1mPRECEDENCE[0m
- Commands specified by [4mlesskey[24m take precedence over the default com-
- mands. A default command key may be disabled by including it in the
- input file with the action "invalid". Alternatively, a key may be
- defined to do nothing by using the action "noaction". "noaction" is
- similar to "invalid", but [4mless[24m will give an error beep for an "invalid"
- command, but not for a "noaction" command. In addition, ALL default
- commands may be disabled by adding this control line to the input file:
-
- #stop
-
- This will cause all default commands to be ignored. The #stop line
- should be the last line in that section of the file.
-
- Be aware that #stop can be dangerous. Since all default commands are
- disabled, you must provide sufficient commands before the #stop line to
- enable all necessary actions. For example, failure to provide a "quit"
- command can lead to frustration.
-
-
-[1mLINE EDITING SECTION[0m
- The line-editing section begins with the line:
-
- #line-edit
-
- This section specifies new key bindings for the line editing commands,
- in a manner similar to the way key bindings for ordinary commands are
- specified in the #command section. The line-editing section consists
- of a list of keys and actions, one per line as in the example below.
-
-
-[1mEXAMPLE[0m
- The following input file describes the set of default line-editing keys
- used by less:
-
- #line-edit
- \t forw-complete
- \17 back-complete
- \e\t back-complete
- ^L expand
- ^V literal
- ^A literal
- \el right
- \kr right
- \eh left
- \kl left
- \eb word-left

- \e0 home
- \kh home
- \e$ end
- \ke end
- \ek up
- \ku up
- \ej down
-
-
-
-[1mLESS ENVIRONMENT VARIABLES[0m
- The environment variable section begins with the line
-
- #env
-
- Following this line is a list of environment variable assignments.
- Each line consists of an environment variable name, an equals sign (=)
- and the value to be assigned to the environment variable. White space
- before and after the equals sign is ignored. Variables assigned in
- this way are visible only to [4mless.[24m If a variable is specified in the
- system environment and also in a lesskey file, the value in the lesskey
- file takes precedence. Although the lesskey file can be used to over-
- ride variables set in the environment, the main purpose of assigning
- variables in the lesskey file is simply to have all [4mless[24m configuration
- information stored in one file.
-
-
-[1mEXAMPLE[0m
- The following input file sets the -i option whenever [4mless[24m is run, and
- specifies the character set to be "latin1":
-
- #env
- LESS = -i
- LESSCHARSET = latin1
-
-
-
-[1mSEE ALSO[0m
- less(1)
-
-
-[1mWARNINGS[0m
- It is not possible to specify special keys, such as uparrow, in a key-
- board-independent manner. The only way to specify such keys is to
- specify the escape sequence which a particular keyboard sends when such
- a key is pressed.
-
- On MS-DOS and OS/2 systems, certain keys send a sequence of characters
- which start with a NUL character (0). This NUL character should be
- represented as \340 in a lesskey file.

-.SH NAME
-lesskey \- specify key bindings for less
-.SH SYNOPSIS
-.B "lesskey [-o output] [--] [input]"
-.br
-.B "lesskey [--output=output] [--] [input]"
-.br
-.B "lesskey -V"
-.br
-.B "lesskey --version"
-.SH DESCRIPTION
-.I Lesskey
-is used to specify a set of key bindings to be used by
-.I less.
-The input file is a text file which describes the key bindings,
-If the input file is "-", standard input is read.
-If no input file is specified, a standard filename is used
-as the name of the input file, which depends on the system being used:
-On Unix systems, $HOME/.lesskey is used;
-on MS-DOS systems, $HOME/_lesskey is used;
-and on OS/2 systems $HOME/lesskey.ini is used,
-or $INIT/lesskey.ini if $HOME is undefined.
-The output file is a binary file which is used by
-.I less.
-If no output file is specified,
-and the environment variable LESSKEY is set,
-the value of LESSKEY is used as the name of the output file.
-Otherwise, a standard filename is used as the name of the output file,
-which depends on the system being used:
-On Unix and OS-9 systems, $HOME/.less is used;
-on MS-DOS systems, $HOME/_less is used;
-and on OS/2 systems, $HOME/less.ini is used,
-or $INIT/less.ini if $HOME is undefined.
-If the output file already exists,
-.I lesskey
-will overwrite it.
-.PP
-The -V or --version option causes
-.I lesskey
-to print its version number and immediately exit.
-If -V or --version is present, other options and arguments are ignored.
-.PP
-The input file consists of one or more
-.I sections.
-Each section starts with a line that identifies the type of section.
-Possible sections are:
-.IP #command
-Defines new command keys.
-.IP #line-edit
-Defines new line-editing keys.
-.IP #env
-Defines environment variables.
-.PP
-Blank lines and lines which start with a pound sign (#) are ignored,

-.SH "COMMAND SECTION"
-The command section begins with the line
-.sp
-#command
-.sp
-If the command section is the first section in the file,
-this line may be omitted.
-The command section consists of lines of the form:
-.sp
- \fIstring\fP <whitespace> \fIaction\fP [extra-string] <newline>
-.sp
-Whitespace is any sequence of one or more spaces and/or tabs.
-The \fIstring\fP is the command key(s) which invoke the action.
-The \fIstring\fP may be a single command key, or a sequence of up to 15 keys.
-The \fIaction\fP is the name of the less action, from the list below.
-The characters in the \fIstring\fP may appear literally, or be
-prefixed by a caret to indicate a control key.
-A backslash followed by one to three octal digits may be used to
-specify a character by its octal value.
-A backslash followed by certain characters specifies input
-characters as follows:
-.IP \eb
-BACKSPACE
-.IP \ee
-ESCAPE
-.IP \en
-NEWLINE
-.IP \er
-RETURN
-.IP \et
-TAB
-.IP \eku
-UP ARROW
-.IP \ekd

-.IP \ekU
-PAGE UP
-.IP \ekD
-PAGE DOWN
-.IP \ekh
-HOME
-.IP \eke
-END
-.IP \ekx
-DELETE
-.PP
-A backslash followed by any other character indicates that character is
-to be taken literally.
-Characters which must be preceded by backslash include
-caret, space, tab and the backslash itself.
-.PP
-An action may be followed by an "extra" string.
-When such a command is entered while running
-.I less,
-the action is performed, and then the extra
-string is parsed, just as if it were typed in to
-.I less.
-This feature can be used in certain cases to extend
-the functionality of a command.
-For example, see the "{" and ":t" commands in the example below.
-The extra string has a special meaning for the "quit" action:
-when
-.I less
-quits, first character of the extra string is used as its exit status.
-

-.SH PRECEDENCE
-Commands specified by

-take precedence over the default commands.
-A default command key may be disabled by including it in the
-input file with the action "invalid".
-Alternatively, a key may be defined
-to do nothing by using the action "noaction".
-"noaction" is similar to "invalid", but
-.I less
-will give an error beep for an "invalid" command,
-but not for a "noaction" command.
-In addition, ALL default commands may be disabled by
-adding this control line to the input file:
-.sp
-#stop
-.sp
-This will cause all default commands to be ignored.
-The #stop line should be the last line in that section of the file.
-.PP
-Be aware that #stop can be dangerous.
-Since all default commands are disabled,
-you must provide sufficient commands before the #stop line
-to enable all necessary actions.
-For example, failure to provide a "quit" command can lead to frustration.
-
-.SH "LINE EDITING SECTION"
-The line-editing section begins with the line:
-.sp
-#line-edit
-.sp
-This section specifies new key bindings for the line editing commands,
-in a manner similar to the way key bindings for
-ordinary commands are specified in the #command section.
-The line-editing section consists of a list of keys and actions,
-one per line as in the example below.

-.I less.
-If a variable is specified in the system environment and also in a
-lesskey file, the value in the lesskey file takes precedence.
-Although the lesskey file can be used to override variables set in the
-environment, the main purpose of assigning variables in the lesskey file
-is simply to have all
-.I less
-configuration information stored in one file.
-
-.SH EXAMPLE

-
-.SH WARNINGS
-It is not possible to specify special keys, such as uparrow,
-in a keyboard-independent manner.
-The only way to specify such keys is to specify the escape sequence
-which a particular keyboard sends when such a key is pressed.
-.PP
-On MS-DOS and OS/2 systems, certain keys send a sequence of characters
-which start with a NUL character (0).
-This NUL character should be represented as \e340 in a lesskey file.

+.br
+.B "lesskey [--output=output] [--] [input]"
+.br
+.B "lesskey -V"
+.br
+.B "lesskey --version"
+.SH DESCRIPTION
+.I Lesskey
+is used to specify a set of key bindings to be used by
+.I less.
+The input file is a text file which describes the key bindings.
+If the input file is "-", standard input is read.
+If no input file is specified, a standard filename is used
+as the name of the input file, which depends on the system being used:
+On Unix systems, $HOME/.lesskey is used;
+on MS-DOS systems, $HOME/_lesskey is used;
+and on OS/2 systems $HOME/lesskey.ini is used,
+or $INIT/lesskey.ini if $HOME is undefined.
+The output file is a binary file which is used by
+.I less.
+If no output file is specified,
+and the environment variable LESSKEY is set,
+the value of LESSKEY is used as the name of the output file.
+Otherwise, a standard filename is used as the name of the output file,
+which depends on the system being used:
+On Unix and OS-9 systems, $HOME/.less is used;
+on MS-DOS systems, $HOME/_less is used;
+and on OS/2 systems, $HOME/less.ini is used,
+or $INIT/less.ini if $HOME is undefined.
+If the output file already exists,
+.I lesskey
+will overwrite it.
+.PP
+The -V or --version option causes
+.I lesskey
+to print its version number and immediately exit.
+If -V or --version is present, other options and arguments are ignored.
+.PP
+The input file consists of one or more
+.I sections.
+Each section starts with a line that identifies the type of section.
+Possible sections are:
+.IP #command
+Defines new command keys.
+.IP #line-edit
+Defines new line-editing keys.

+The \fIstring\fP may be a single command key, or a sequence of up to 15 keys.
+The \fIaction\fP is the name of the less action, from the list below.
+The characters in the \fIstring\fP may appear literally, or be
+prefixed by a caret to indicate a control key.
+A backslash followed by one to three octal digits may be used to

- * Code to handle displaying line numbers.
- *
- * Finding the line number of a given file position is rather tricky.
- * We don't want to just start at the beginning of the file and
- * count newlines, because that is slow for large files (and also
- * wouldn't work if we couldn't get to the start of the file; e.g.
- * if input is a long pipe).
- *
- * So we use the function add_lnum to cache line numbers.
- * We try to be very clever and keep only the more interesting
- * line numbers when we run out of space in our table. A line
- * number is more interesting than another when it is far from
- * other line numbers. For example, we'd rather keep lines
- * 100,200,300 than 100,101,300. 200 is more interesting than
- * 101 because 101 can be derived very cheaply from 100, while
- * 200 is more expensive to derive from 100.
- *
- * The function currline() returns the line number of a given
- * position in the file. As a side effect, it calls add_lnum
- * to cache the line number. Therefore currline is occasionally
- * called to make sure we cache line numbers often enough.

+ * simple cases. They are:
+ *
+ * regstart char that must begin a match; '\0' if none obvious
+ * reganch is the match anchored (at beginning-of-line only)?
+ * regmust string (pointer into program) that match must include, or NULL
+ * regmlen length of regmust string
+ *
+ * Regstart and reganch permit very fast decisions on suitable starting points
+ * for a match, cutting down the work a lot. Regmust permits fast rejection
+ * of lines that cannot possibly match. The regmust tests are costly enough
+ * that regcomp() supplies a regmust only if the r.e. contains something
+ * potentially expensive (at present, the only such thing detected is * or +
+ * at the start of the r.e., which can involve a lot of backup). Regmlen is
+ * supplied because the test in regexec() needs it and regcomp() is
+ * computing it anyway.

+ * Structure for regexp "program". This is essentially a linear encoding
+ * of a nondeterministic finite-state machine (aka syntax charts or
+ * "railroad normal form" in parsing technology). Each node is an opcode
+ * plus a "next" pointer, possibly plus an operand. "Next" pointers of
+ * all nodes except BRANCH implement concatenation; a "next" pointer with
+ * a BRANCH on both ends of it is connecting two alternatives. (Here we
+ * have one of the subtle syntax dependencies: an individual BRANCH (as
+ * opposed to a collection of them) is never concatenated with anything
+ * because of operator precedence.) The operand of some types of node is
+ * a literal string; for others, it is a node leading into a sub-FSM. In
+ * particular, the operand of a BRANCH node is the first node of the branch.
+ * (NB this is *not* a tree structure: the tail of the branch connects
+ * to the thing following the set of BRANCHes.) The opcodes are:
