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 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.Z. If two files
are specified, then they are uncompressed (if ending with ".Z") 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.
