nohup and disown

GNU Screen is good for "detaching" jobs associated with a particular terminal, so that the job carries on even when, for example, the terminal is killed, or you log out from a server.

"nohup" and "disown" are other useful Linux commands with a far shallower learning curve.

Case A: You know before-hand that you want to run a background job without interruption

nohup foo&

Case B: You submitted several background jobs, but now you want the jobs to persist even after you kill the terminal


Or if you want to disown only a particular job, use the "jobs" command to find out job-ids and,

disown %1 # disowns only foo1

Here is a nice thread on StackExchange on the difference between nohup and disown.
