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 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)
