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.  On systems with
a 14 char limitation on file names, the original name is
truncated to make room for the .gz suffix. For example,
12345678901234 is renamed to 12345678901.gz. A file name
such as foo.tgz is left intact.
