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
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), zmore(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.
