In this tutorial, we will show you how to install Tmux Terminal Multiplexer on Linux. For those of you who didn’t know, Tmux is a terminal multiplexer that lets you switch easily between several programs in one terminal, detach them (they keep running in the background), and reattach them to a different terminal. Tmux provides a number of advanced features, such as the ability to split the terminal into multiple panes, the ability to create and manage multiple windows, and the ability to synchronize input and output between different panes and windows. Additionally, Tmux provides a number of ways to customize its behavior and appearance, such as through the use of configuration files and environment variables.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Tmux Terminal Multiplexer on Linux.

Prerequisites

A server running one of the following operating systems: Ubuntu Debian-based, or CentOS RHEL-based.
It’s recommended that you use a fresh OS install to prevent any potential issues.
A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

sudo apt update
