Tmux

Tmux is a terminal multiplexer: it allows users to manage multiple terminal sessions from a single window, with the critical ability to detach and reattach.

This technology is a game-changer for terminal power users. Tmux operates as a terminal multiplexer, enabling you to run multiple programs within a single interface, managing them across distinct sessions, windows, and panes. Its core value is persistence: you can start a long-running process, detach the session (using the default prefix key, `Ctrl+B`, then `D`), close your SSH connection, and reattach later from any machine to find the job still running. Furthermore, it facilitates organization by allowing a single window to be split into multiple rectangular panes (e.g., horizontally with `Ctrl+B %` or vertically with `Ctrl+B "`), effectively acting as a window manager for your command line.
