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, which is useful for running more than one command-line program at the same time. Tmux acts as a window manager within your terminal and allows you to create several "pseudo terminals" from a single terminal. This is especially useful for running multiple programs with a single connection.
Tmux has several key features, including the ability to partition the tmux window into multiple "panes," each with its own command line. It also 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 its own set of windows and panes. Tmux is scriptable, configurable, and ships with a powerful command system that allows you to retrieve and manipulate information on its objects.
Tmux is generally used to increase productivity by splitting a terminal window for each new task you have running. It is ideal for speeding up terminal tasks on your virtual private server (VPS), especially if you are a sysadmin who needs to handle several terminals simultaneously. Tmux is available in the standard repositories with Fedora and Red Hat Enterprise Linux (RHEL), starting with RHEL 8. It is also available with many other Linux distributions, and you should be able to install it by using your favorite distribution package manager.
