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.
