GZGREP(1)						      General Commands Manual							 GZGREP(1)

NAME

       gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression

SYNOPSIS

       gzgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       gzgrep 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 speci-
       fied, 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  gzgrep  is  invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, gzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	gzgrep string files
	   for csh: (setenv GREP fgrep; gzgrep string files)
