The screen command allows you to detach a running process from a session and then reattach it at a later time. Its use is simple:
user@debian:~$ screen yourlinuxcommand
Now that yourlinuxcommand is executing, press Ctrl+A followed by D to detach the screen.
Obtain a list of all the running screen processes:
user@debian:~$ screen -ls
There is a screen on:
18470.pts-0.server(02/03/14 10:03:43) (Detached)
1 Socket in /var/run/screen/S-user.
Note the screen id in the above output. Use the screen id to reattach the session at anytime:
user@debian:~$ $ screen -r 18470.pts-0.server
