tmux

Definitions

1. A terminal multiplexer that lets you create, split, and manage multiple terminal sessions within a single window, persist them across SSH disconnects, and share them between users — the modern successor to GNU Screen.

   In plain English: A tool that lets you run multiple terminal windows inside one, and keeps them alive even if you disconnect.

   Example: "I run my dev server in a tmux session on the remote box so it keeps running even when my laptop goes to sleep."
