zgrep - Unix, Linux Command
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ]
[ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the
grep on compressed or gziped files. All options specified are passed directly to
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
grep.
If
zgrep is invoked as
zegrep or
zfgrep then
egrep or
fgrep is used instead of
grep. If the GREP environment variable is set,
zgrep uses it as the
grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
