Muck It Up With Tmux

Using and Configuring Tmux

Managing multiple sessions in the same terminal? Consider Tmux, a handy "terminal multiplexer." Joe Brockmeier takes a look at its basic usage and configuration on ServerWatch.

To start tmux, just run tmux or tmux new-session if you're feeling verbose. Then you'll have a session with one window and your usual login shell. To add a second window, run Ctrl-b c. (Same thing if you want a third, fourth, and so on.)

If you'd like to split your window into panes, each with its own shell, run Ctrl-b " to split the window into two panes. That will split your tmux session horizontally. If you prefer vertically, you can use Ctrl-b %. To move between panes use Ctrl-b o.

Now, all of the windows that are running in tmux are in one session. If you start a second instance of tmux in another xterm or virtual console on the same machine, you've got a second session. You can see all of the sessions that are running by using Ctrl-s. This will give a menu of all sessions and show how many windows are running in each session.
