Tmux
tmux is a terminal multiplexer, an advanced tool for running multiple tasks on the command line. It enhances the functionality of a standard terminal session, enabling the user to use multiple sessions in a single window.
The main tmux window can be divided into smaller window "panes." Each pane can run different tasks on the same computer, or on different computers, either on the Internet or your local network. Tmux can save your session state, maintaining network connections and allowing processes to continue running after the terminal application is closed. Sessions can be restored later, so you can continue where you left off.
First released in 2007, tmux is free and open-source software. It's available for Unix-like operating systems, including Linux, BSD (Berkeley Software Distribution), macOS, and Windows 10 (if WSL (Windows Subsystem for Linux) is installed).
