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 pro-
       gram on  compressed  files.   All  options  specified  are
       passed  directly to cmp or diff.  If only 1 file is speci-
       fied, then the files compared  are  file1  and  an  uncom-
       pressed  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.
