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 files compressed via
       gzip.  All options specified are passed directly  to  cmp  or  diff.   If  only  file1  is
       specified,  it  is  compared  to  the uncompressed contents of file1.gz.  If two files are
       specified, their contents (uncompressed if necessary) are fed to cmp or diff.   The  input
       files are not modified.  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 may refer to file names such as "-" instead of to
       the file names specified.
