When the session is detached or there is a network disruption, the process that is started in a screen session will still run and you can re-attach to the screen session at any time. This also comes in handy if you want to run a long process persistently or connect to shell sessions from multiple locations. - -In this article, we will show the basics of installing and using screen on a Linux VPS. - -### How to install screen - -Screen comes preinstalled on some of the popular distributions. You can check if it is installed on your server using the following command - -``` -screen -v -Screen version 4.00.03 (FAU) -``` - -If you do not have screen to the VPS, you can easily install it using the package manager provided by the OS. - -### [CentOS][4]/RedHat/Fedora - -``` -yum -y install screen -``` - -### [Ubuntu][5]/[Debian][6] - -``` -apt-get -y install screen -``` - -### How to start a screen session - -You can start screen by typing ‘screen’ at the command prompt and a new screen session will be started which looks the same as the command prompt - -``` -screen -``` - -It is a good practice to start screen sessions with descriptive names so you can easily remember which process is running in the session. To create a new session with a session name run the following command - -``` -screen -S name -``` - -and replace ‘name’ with a meaningful name for your session. - -### Detach from screen session - -To detach from the current screen session you can press ‘Ctrl-A‘ and ‘d‘ on your keyboard. All screen sessions will still be active and you can re-attach to them at any time later. - -### Reattach to screen session - -If you have detached from a session or your connection is interrupted for some reason, you can easily re-attach by executing the following command: - -``` -screen -r -``` - -If you have multiple screen sessions you can list them with ‘ls’ - -``` -screen -ls - -There are screens on: -7880.session    (Detached) -7934.session2   (Detached) -7907.session1   (Detached) -3 Sockets in /var/run/screen/S-root. -``` - -In our example, we have three active screen sessions.
