Bash - Tmux


Terminal Multiplexer. Used to open a lot of sessions in a single window. Can create tabs and split a window into multiple parts. Tmux sessions stay active even after closing a connection (ssh), so it is a handy way to keep your work or have running process run in the background when you're not connected to the host.

My personal ".tmux.conf" file can be found HERE. My plugin install script can be found HERE.
