To run it in the background, so you can do other things while it's zipping.

Absolutely Right by scottn
Actually "&" told to shell to do this process in background,
If u want to look this process use following command.

fg 1

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

^z ie ctrl+z

Best Luck. Smilie
