tmux is an open-source terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time. It can also be used to detach processes from their controlling terminals, allowing remote sessions to remain active without being visible.[3]

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.
Some notable tmux features are:[4]
Tmux lacks built-in serial port and telnet support.[4] It uses different command keys from the ones used by screen, so it is not a drop-in replacement for screen, but it can be configured to use compatible keybindings.
tmux is included in the OpenBSD base system,[7] and is available as a package for many other Unix-like operating systems.[6]
