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 file1 is specified, it is compared to the uncom-
pressed contents of file1.gz. If two files are specified, their con-
tents (uncompressed if necessary) are fed to cmp or diff. The input
files are not modified. The exit status from cmp or diff is preserved.
cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1),
Messages from the cmp or diff programs may refer to file names such as
"-" instead of to the file names specified.
