     ZDIFF(1)                  UNIX System V                  ZDIFF(1)

     NAME
          zcmp, zdiff - compare compressed files

     SYNOPSIS
          zcmp [ cmp_options ] file1 [ file2 ]
          zdiff [ diff_options ] file1 [ file2 ]

     DESCRIPTION
          Zcmp and zdiff are used to invoke the cmp or the diff
          program on compressed files.  All options specified are
          passed directly to cmp or diff.  If only 1 file is
          specified, then the files compared are file1 and an
          uncompressed file1.gz.  If two files are specified, then
          they are uncompressed if necessary and fed to cmp or diff.
          The exit status from cmp or diff is preserved.

     SEE ALSO
          cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1),
          gzip(1), gzexe(1)

     BUGS
          Messages from the cmp or diff programs refer to temporary
          filenames instead of those specified.
