tmux – terminal multiplexer software

tmux is a “terminal multiplexer”. This application enables a number of terminals (or windows) to be created, accessed and controlled from a single screen.

tmux runs as a server-client system. A server is created automatically when necessary and holds a number of sessions, each of which may have a number of windows linked to it.The tmux server manages clients, sessions, windows and panes.

Any number of clients may connect to a session, or the server may be controlled by issuing commands with tmux. Communication takes place through a socket, by default placed in /tmp.

tmux provides a consistent and well-documented command interface, with the same syntax whether used interactively, as a key binding, or from the shell. It offers a choice of vim or Emacs key layouts.

tmux is included in the base system of OpenBSD.

  • Uses a clearly defined client-server model.
