tmux

tmux is a terminal multiplexor that "lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal."

Start a new session: %tmux
Exit the current session: Ctrl+B, then release and hit D
List sessions: %tmux list-sessions (returns a numbered list of sessions)
Resume a session: %tmux attach -t [number of session]
