This question already has an answer here:

While I am always logging into a CentOS server for simulations it got me thinking:

why can't I keep running the simulations even if my session is closed?

I know that when a session is ended or a user logs out,

any process generated from the session is also terminated.

Could there be a way to let the processes keep on running by itself

even if the session is closed?

-- a silly question from a user with not much unix background :)

Have a look at screen or, even better, tmux.

These allow you to do exactly what you want. tmux also allows you to split the session into multiple windows.

thanks! I'm looking at screen and it looks nice already! – kwagjj Jun 18 '14 at 14:24

Sure there is! tmux and screen are both classic solution as well as nohup.
