tmux

Tmux is an open-source terminal multiplexer that replaces the GNU screen. It allows you to access multiple terminal sessions simultaneously in a single window. You can run more than one command-line program at the same time and easily switch between multiple programs in one terminal. This terminal session protects your programs from accidentally disconnecting by decoupling them from the main terminal. Also, it is scriptable which lets you create custom tmux sessions for different purposes.
