gzforce

GZFORCE(1)						      General Commands Manual							GZFORCE(1)

NAME

       gzforce - force a '.gz' extension on all gzip files

SYNOPSIS

       gzforce [ name ...  ]

DESCRIPTION

       gzforce	forces a .gz extension on all gzip files so that gzip will not compress them twice.  This can be useful for files with names trun-
       cated 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.

SEE ALSO

       gzip(1), gznew(1), gzmore(1), gzgrep(1), gzdiff(1), gzexe(1)

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
