[sclug] Leave a process running after logging out?

The process is probably quitting because it has received a SIGHUP.

After you pause ("ctrl-z") and background ("bg") your process, use
"disown" to prevent bash from sending it a SIGHUP when you logout.

Unfortunately, after you logout the output of the process is lost -
although it will continue to run, until it finishes.

If you want to capture the output of a command after logout,
you must remember to launch it using "screen" or "nohup".
