Screen is a terminal multiplexer, which allows a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session (such as when using SSH).
Installation
The screen package can be installed on Ubuntu using any method. Starting with the Jaunty release, the screen-profiles package provides advanced features such as status bars, clocks, and notifiers. The package can also be manually installed on previous Ubuntu releases.
Usage
Screen can be started by typing
screen
in a terminal. Press Enter after reading the introductory text. Virtual terminals in Screen can be manipulated by pressing the Ctrl+A key combination, and subsequently pressing a key to execute one of the commands given below:
- c creates a new virtual console
- n switches to the next available virtual console
- p switches back to the previous virtual console
- " lists all available virtual consoles and their assigned numbers
- hitting a number key brings the corresponding virtual console to the foreground
- Esc lets you scroll back and forth in your terminal output
- d detatches the current screen sessions and brings you back to the normal terminal
When a Screen session is detached, the processes that were running inside it aren't stopped. You can re-attach a detached session by typing
screen -r
in a terminal
To remove the annoying copyright notice at startup, edit your /etc/screenrc withgksudo gedit /etc/screenrcand remove the hash which begins the line
#startup_message off
Save the file, and you will not see it again :D For further information and more advanced commands, you can refer to the screen man page.
