NAME
       gzcmp, gzdiff - compare compressed files

SYNOPSIS
       gzcmp [ cmp_options ] file1 [ file2 ]
       gzdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION
       gzcmp  and  gzdiff 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), gzmore(1), gzgrep(1), gznew(1), gzforce(1), gzip(1), gzexe(1)

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