fg 1

If u want to send this back to background use following command.

^z ie ctrl+z

Best Luck. Smilie

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: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWgzip | +--------------------+-----------------+ |Interface Stability | Committed | +--------------------+-----------------+ NOTES
