You should look for modern alternatives like tmux.
tmux is superior to screen for many reasons, here are just some examples:
- Windows can be moved between session and even linked to multiple sessions
- Windows can be split horizontally and vertically into panes
- Support for UTF-8 and 256 colour terminals
- Sessions can be controlled from the shell without the need to enter a session
To get the same functionality as explained in the answer recommending screen, you would need to do the following:
- ssh into the remote machine
- start tmux by typing tmux into the shell
- start the process you want inside the started tmux session
- leave/detach the tmux session by typing Ctrl+b and then d
You can now safely log off from the remote machine, your process will keep running inside tmux. When you come back again and want to check the status of your process you can use tmux attach to attach to your tmux session.
If you want to have multiple sessions running side-by-side, you should name each session using Ctrl+b and $. You can get a list of the currently running sessions using tmux list-sessions or simply tmux ls, now attach to a running session with command tmux attach-session -t.
