tmux / tmux


tmux source code

Welcome to tmux!

tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
to be accessed and controlled from a single terminal. tmux is intended to be a
simple, modern, BSD-licensed alternative to programs such as GNU screen.

This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris.

tmux depends on libevent 2.x. Download it from:

It also depends on ncurses, available from:

To build and install tmux from a release tarball, use:

	$ ./configure && make
	$ sudo make install

tmux can use the utempter library to update utmp(5), if it is installed - run
configure with --enable-utempter to enable this.

To get and build the latest from version control:

	$ git clone
	$ cd tmux
	$ sh
	$ ./configure && make

(Note that this requires at least a working C compiler, make, autoconf,
automake, pkg-config as well as libevent and ncurses libraries and headers.)

For more information see Patches should be sent by email to
the mailing list at or submitted through GitHub at

For documentation on using tmux, see the tmux.1 manpage. It can be viewed from
the source tree with:

	$ nroff -mdoc tmux.1|less

A small example configuration in example_tmux.conf.

And a bash(1) completion file at:

For debugging, running tmux with -v or -vv will generate server and client log
files in the current directory.
