tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

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

tmux depends on libevent 2.x, available from this page.

It also depends on ncurses, available from this page.

To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed.

Some platforms provide binary packages for tmux, although these are sometimes out of date. Examples are listed on this page.

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.

For more detailed instructions on building and installing tmux, see this page.

To get and build the latest from version control - note that this requires autoconf, automake and pkg-config:

git clone https://github.com/tmux/tmux.git
cd tmux
sh autogen.sh
./configure && make
