# Welcome to tmux!

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, OS X and Solaris.

## Dependencies

tmux depends on [libevent](https://libevent.org) 2.x, available from [this
page](https://github.com/libevent/libevent/releases/latest).

It also depends on [ncurses](https://www.gnu.org/software/ncurses/), available
from [this page](https://invisible-mirror.net/archives/ncurses/).

## Installation

### From release tarball

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

~~~bash
./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.

### From version control

To get and build the latest from version control:

~~~bash
git clone https://github.com/tmux/tmux.git
cd tmux
sh autogen.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.)
