Tmux is a command-line tool which lets you run and manage multiple programs in one single terminal, and is commonly used on remote machines accessed via SSH.
You may find this tool particularly useful when you need to deal with, and keep an eye on, time-consuming processes that you run on a remote server.
Simply put, tmux allows you to reattach running programs to another terminal after logging off from an SSH session.
In a typical workflow, you create a tmux session or attach to an existing one. Within a session, you manage multiple windows which are basically virtual terminals where you run programs.
