.SH DESCRIPTION
|
|
.IR Zgrep
|
|
is used to invoke the
|
|
.I grep
|
|
on compress'ed or gzip'ed files. All options specified are passed directly to
|
|
.I grep.
|
|
If no file is specified, then the standard input is decompressed
|
|
if necessary and fed to grep.
|
|
Otherwise the given files are uncompressed if necessary and fed to
|
|
.I grep.
|
|
.PP
|
|
If
|
|
.I zgrep
|
|
is invoked as
|
|
.I zegrep
|
|
or
|
|
.I zfgrep
|
|
then
|
|
.I egrep
|
|
or
|
|
.I fgrep
|
|
is used instead of
|
|
.I grep.
|
|
If the GREP environment variable is set,
|
|
.I zgrep
|
|
uses it as the
|
|
.I grep
|
|
program to be invoked. For example:
|
|
|
|
for sh: GREP=fgrep zgrep string files
|
|
for csh: (setenv GREP fgrep; zgrep string files)
