tmux is a "terminal multiplexer". It makes it so that you can use multiple programs in one terminal application, keep them running in the background even if you've left the application, reattach them later, attach them to a different terminal app, and more. People find it especially useful for running programs in SSH windows (if tmux is running a program in an SSH window and the connection drops, the program will keep running). ## Install ### MacOS ```bash brew install tmux ``` ### Ubuntu / Debian ```bash apt install tmux ``` ### RHEL / CentOS ```bash yum install tmux ``` ## See Also [[tmux Commands]] [[tmux Configuration]]
