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 com-
    pressed 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.
