ZGREP(1)                 USER COMMANDS                   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)
