tmux

‘tmux’ allows a user to use 1 terminal window to access multiple separate terminal sessions. It lets you keep running them in the background by detaching them and then reattach them to a different terminal.

$ tmux
$ tmux new -s myname
$ tmux a -t myname
$ tmux ls
$ tmux kill-session -t myname

Useful Options / Examples

CTRL-B + % or CTRL-B + "

% represents a vertical split, while “ represents a horizontal split. This will split the terminal window into multiple terminal sessions. Use CTRL-B + arrow keys to navigate.
