Running commands in the terminal allows you to do many tasks more quickly than you could using a graphical application. But command prompts aren’t all that great for multitasking, at least not without some help. And that’s where tmux comes in.
Tmux or terminal multiplexer is a command line program that enables you to run and view multiple commands in a single terminal window simultaneously. Each command exists in its own window pane as though you were using a full-blown tiling window manager.
To help you get started with tmux, we have compiled key tmux terms and commands in the cheat sheet below.

More Help With the Linux Command Line
The commands above help you work in tmux using multiple panes, windows, and sessions. If you really want to make tmux your own, you can go further by editing the configuration file stored at the following location:
/etc/tmux.conf
You can also try your hand at scripting.
When you’re working exclusively from the terminal, installing tmux is akin to installing a window manager. This gives you more flexibility when working on servers or other devices without an attached screen. Have fun exploring tmux!
