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 one file is specified, then it is
compared to a file with the same name without the .gz
extension. If two files are specified, then they are
uncompressed if necessary and fed to cmp or
diff. The exit status from cmp or diff
When both files
must be uncompressed before comparison, the second is
uncompressed to /tmp. In all other cases,
zdiff and zcmp use only a pipe.
the cmp or diff programs refer to temporary
filenames instead of those specified.
