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.
