@ - & won't cut it

Appending an ampersand to the end of a command does give you the command line back, however the command itself is still attached to the shell process so if the shell dies, the command dies with it. So it's no good for starting a process you want to continue to run AFTER your shell dies, ex. from disconnecting an SSH client. --Jimbo 14:04, 17 September 2007 (EDT)
