zcmp, zdiff - compare compressed files
zcmp [ cmp_options ] file1 [ file2 ]
zdiff [ diff_options ] file1 [ file2 ]
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 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.

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