ZGREP(1)                                                                                            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)
