       zgrep - search possibly compressed files for a regular expression

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

       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 nec-
       essary 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

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