     ZGREP(1)                  UNIX System V                  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)
