The GNU/Linux screen program is quite unknown, except for geeks & *nix experts, it helps you create multiple terminal sessions from a single one and lets you detach from the screen, at the same time maintaining the sessions as if you had never left the session and you can attach/connect to the session anytime you want afterwards. Another feature of the screen program is that it allows multiple people to use the same sessions, thereby providing a terminal session 'sharing' feature. In this article we'll be looking into using screen to create and manage multiple sessions. Using screen Command First let's look at starting a screen session, it can be simply started with, Code: $ screen but, that will have a arbitrary screen session name chosen by the screen program. So, this would be more suited, Code: $ screen -S my_tail_log This will immediately start a new session and attach it, in case you want to start a screen in detached mode, useful for startup scripts, try this Code: $ screen -dm -S my_tail_log To resume a detached screen, Code: $ screen -r my_tail_log To attach to an already attached running screen (say for sharing, multiple users can attach to the same session) Code: $ screen -x my_tail_log To create a new window inside a screen when attached to it, use Ctrl + A and then C. To view the list of running windows in a screen and select one from the list, use Ctrl + A and then ". To change a window's title, use Ctrl + A and then capital A. To detach from a screen, use Ctrl + A and then D. To list all the running screens, Code: $ screen -ls You can use multiple windows inside a screen to work on different things, say one for editing code, another for executing the programs, and another one to view logs/debugging etc. It's very easy to share working while on a teleconferencing call and all users can see, execute & discussion commands and outputs.
