The Linux tmux and GNU screen commands are terminal multiplexers – in brief, these commands let a user launch and use multiple shell sessions from a single ssh session.
The screen or tmux commands also allow a user to initiate a command from one start a process in a terminal, disconnect from that terminal, and then reconnect from a different location to that same terminal without having to restart the commandprocess.
