Tmux
Updated 30 January 2020
tmux is an open source terminal multiplexer tool that gives user access to multiple terminal on one screen. With tmux, you can join and quit the current session, while all running programs and process remain. It comes with all Calculate Linux Desktop and Calculate Directory Server and flavours.
Start
To start tmux, run:
tmux
Session 0 will be run then.
To close a session with a single open window, run:
exit
Tmux can be commanded both from the terminal and the current sessions, by hot keys. To view the full list of supported commands, run:
tmux list-commands
