.SH DESCRIPTION |
| 22 |
.IR Bzgrep |
| 23 |
is used to invoke the |
| 24 |
.I grep |
| 25 |
on bzip2-compressed files. All options specified are passed directly to |
| 26 |
.I grep. |
| 27 |
If no file is specified, then the standard input is decompressed |
| 28 |
if necessary and fed to grep. |
| 29 |
Otherwise the given files are uncompressed if necessary and fed to |
| 30 |
.I grep. |
| 31 |
.PP |
| 32 |
If |
| 33 |
.I bzgrep |
| 34 |
is invoked as |
| 35 |
.I bzegrep |
| 36 |
or |
| 37 |
.I bzfgrep |
| 38 |
then |
| 39 |
.I egrep |
| 40 |
or |
| 41 |
.I fgrep |
| 42 |
is used instead of |
| 43 |
.I grep. |
| 44 |
If the GREP environment variable is set, |
| 45 |
.I bzgrep |
| 46 |
uses it as the |
| 47 |
.I grep |
| 48 |
program to be invoked. For example: |
| 49 |
|
| 50 |
for sh: GREP=fgrep bzgrep string files |
| 51 |
for csh: (setenv GREP fgrep; bzgrep string files) |
