Tmux is a terminal multiplexer which enables a number of terminals to be created, accessed, and controlled from a single screen. Tmux may be detached from a screen and will still continue to run in the background, then later reattached.

Whenever tmux is started it creates a new session with a single window and displays it on screen. A status line at the bottom of the screen shows information on the current session and is used to enter interactive commands.
