NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

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

DESCRIPTION

       The  zcmp  and  zdiff  commands  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.
