tmux is a terminal multiplexer, allowing a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session. It is useful for dealing with multiple programs from a command-line interface, and for separating programs from the Unix shell that started the program.[2] It provides much of the same functionality as GNU Screen, but it is distributed under a BSD-like license.


tmux includes most features of GNU Screen. It allows users to start a terminal session with clients that are not bound to a specific physical or virtual console; multiple terminal sessions can be created within a single terminal session and then freely rebound from one virtual console to another, and each session can have several connected clients. The features that differentiate tmux from GNU Screen are[3]

  • menus for interactive selection of running sessions, windows or clients
  • window can be linked to an arbitrary number of sessions[4]
  • vi-like or Emacs command mode (with auto completion) for managing tmux[5]
  • lack of built-in serial and telnet clients (which some consider bloat for the terminal multiplexer)[3]
  • easier configuration[6][7][better source needed]
  • different command keys—it is not a drop-in replacement for screen, but can be configured to use compatible keybindings


tmux enjoys wide adoption; it can be found in software repositories of nearly all UNIX-like operating systems[5] and is included in the base system of OpenBSD.[2]
