zgrep(1)
ZGREP(1) USER COMMANDS ZGREP(1)
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 compress'ed or gzip'ed
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)
