Screen is a full-screen software program that can be used to multiplexes a physical console between several processes (typically interactive shells). It offers a user to open several separate terminal instances inside a one single terminal window manager.
The screen application is very useful, if you are dealing with multiple programs from a command line interface and for separating programs from the terminal shell. It also allows you to share your sessions with others users and detach/attach terminal sessions.
Screen Command Examples
On my Ubuntu 10.04 Server Edition, Screen has been installed by default. But, in Linux Mint does not have screen installed by default, I need to install it first using apt-get command before using it. Please follow your distribution installation procedure to install screen.
Actually, Screen is a very good command in Linux which is hidden inside hundreds of Linux commands. Let’s start to see the function of Screen.
Start screen for the first time
Just type screen at the command prompt. Then the screen will show with interface exactly as the command prompt.
Show screen parameter
When you enter the screen, you can do all your work as you are in the normal CLI environment. But since the screen is an application, so it have command or parameters.
Type “Ctrl-A” and “?” without quotes. Then you will see all commands or parameters on screen.
