ZGREP(1) MachTen Programmer’s Manual 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 decom-
pressed 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)
