zforce - force a .gz extension on all gzip files
zforce name ...
zforce forces a .gz extension on all gzip files so that gzip will not compress them twice. This can be useful for files with names truncated after a file transfer. For example, 12345678901 is renamed to 12345678901.gz. A file name such as foo.tgz is left intact.
