What is it?

Wikipedia

tmux is a software application that can be used to multiplex several virtual consoles, allowing a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session

tmux wiki

tmux is a terminal multiplexer. It 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. And do a lot more

Tmux - what I use it for

• it helps me to organise my desktop in such a way, that I have only one terminal open but still as many terminal sessions as I please
• it allows me to start jobs on remote machines and have them run overnight without me having to stay logged in
• it has X-forwarding capabilies if needed

Get it, docs, manuals

• linux distributions like Ubuntu ship it as a package (get it via apt-get)
• on remote clusters without root permissions you might need to compile it yourself (really easy!)
  • get it from the tmux github page
  • before you compile tmux you'll need to build libevent
  • you'll also need ncurses
• for quick references on key-bindings use, e.g., this cheat sheet or this one here
• you can configue key-bindings and like by creating a file called .tmux.conf in your $HOME directory
