Tmux Quickstart

Terminal multiplexers are applications described as offering a single management pane that allows control and maintenance over multiple terminal sessions.

Tmux initially released in 2007 and is the original open-source terminal multiplexer for Unix-like operating systems. As well as command-line program management, it can also detach processes from their controlling terminals, allowing remote sessions to remain active without being visible.

Installation

Full instructions are available from the tmux GitHub README.

For Mac users, using homebrew, it's a single, simple command:

brew install tmux

Up & Running

Running the program is as you might expect:

tmux

You should find yourself in a new terminal environment. At this moment, not too much differs from a default terminal session, but do note the new control panel on the bottom edge.

Mac OSX iTerm/Tmux Backspace Fault

Should you also encounter a glitch with the backspace functionality not correctly removing characters, consider the guidance offered in this Stack Overflow answer. The gist is to run these commands to extend the base configuration:

curl -LO https://invisible-island.net/datafiles/current/terminfo.src.gz && gunzip terminfo.src.gz

sudo /usr/bin/tic -xe tmux-256color terminfo.src
