If you have a VPS, it is possible that this did not come with a user interface, and you are using the command-line interface. This means that you are most likely using SSH to connect to your VPS. One of the risks that you run during your remote terminal session is the loss of connectivity. This is a problem, especially if you happen to be in the middle of a large task where you end up losing whatever you were working on at the time. The screen application helps mitigate any connection issues you may run into. By running the screen command, you will be able to lose connectivity and resume later, allowing you to pick up where you left off.
Start your screen session, also known as a window
If you lose connectivity, simply ssh back into your server and reconnect to your screen session.
One of the added benefits is that you can have multiple windows running during your terminal session.
To display how many screen sessions you have running, type the following command.
Reattach to screen session.
screen -r 13458
