Screen

screen is a screen manager with VT100/ANSI terminal emulation. It is the older brother of tmux, which shares quite the same concepts.

Basics

• Start a screen session (creates a single window with a shell in it):

screen

• OR start a linux command in a screen session:

screen <linux command>

• Invoke a screen control command (it consists of a "Ctrl + a" followed by one other character):

C-a <command_char>

Basics screen commands are :

C-a C-c : Create a new window with a shell and switch to that window.
C-a "   : Present a list of all windows for selection.
C-a A   : Allow  the  user to enter a name for the current window.
C-a C-k : Kill current window

Further options are available in the man pages.

• Detach from this screen terminal (program continues to run when its associated screen session is detached):

C-a d : Detach screen from this terminal.

• Reattach a session (brings foreground a previously detached session):

screen -r

• Invoke a screen customization command (used to set options):

C-a : <customization_command>
