4 LEVELS · 42 TASKS · REAL TERMINAL

Learn tmux by doing it, not reading about it.

Short levels from your first session to your own config. Every task happens in a live terminal. We watch it and tick things off the moment you get them right.

HOW A LESSON WORKS

The terminal stays put. It changes as you do.

Still the same session you started at the top of the page: window3:lesson, opened when you pressed the prefix. Every task below drives it.
