Tmux Quick Start

What’s tmux?

Tmux is a "terminal multiplexer", it enables a number of terminals (or windows) to be accessed and controlled from a single terminal. It allows you to create a session on a remote box, run applications in that remote session, "detach" from the session, and re-"attach" when desired. It also has advanced features such as multiple windows and split views. Using tmux is recommend when running an interactive CLI program remotely. If you get disconnected from your session, you can re-attach as though nothing happened.

Why tmux?

Tmux lets you run tasks persistently on remote box, so you can safely disconnect/detach and reconnect/reattach without interrupting these running tasks. It is powerful, extensible and can save more working time when combined with the shortcuts.


Most platforms provide binary packages for tmux. Use the command below to install from binary.

# Debian, Ubuntu
$ sudo apt-get install tmux

# RHEL/CentOS/Fedora
$ sudo yum install tmux

# MacOS
$ brew install tmux

If you need the latest version, use the commands below to install from source.

git clone
cd tmux
./configure && make
