Screen: how to run processes in the background after log out

Screen can create multiple windows in a shell, from which you can "detach" and leave them running in the background, even if you log out of your user account.

$ screen -S [choose-a-window-name]

From this window you can type any command and leave it running in the background.

To detach from the window and go back to the terminal, just press the combination:

ctrl-a d

$ screen -r [window-name]

to revert a previously created screen. If you do not remember the window name, you can list them through the command:

$ screen -ls

$ screen -X -S [window-name] kill
