Tmux

SSH into a server, start a long-running process, lose connection, lose everything. tmux solves this by keeping sessions alive independently of your terminal. Why tmux? Persistence: Sessions survive disconnections Multiplexing: Multiple windows and panes in one terminal Remote pairing: Share sessions with teammates Scriptable: Automate complex layouts Basic Concepts t ├ │ │ │ │ └ m ─ ─ u ─ ─ x S ├ │ │ └ S e ─ ─ e s ─ ─ s s s i W ├ └ W i o i ─ ─ i o n n ─ ─ n n d d ( o P P o 2 n w a a w a n n m 1 e e 2 e d ( 1 2 l c i o k l e l e a c t t i a o b n ) o f w i n d o w s ) Getting Started 1 2 3 4 5 6 7 8 9 10 11 12 13 14 # Start new session tmux # Start named session tmux new -s myproject # List sessions tmux ls # Attach to session tmux attach -t myproject # Attach to last session tmux attach The Prefix Key All tmux commands start with a prefix (default: Ctrl+b), then a key. ...

If you SSH into servers, run long processes, or just want a better terminal experience, tmux changes everything. Sessions persist through disconnects, panes let you see multiple things at once, and once you build muscle memory, you’ll wonder how you worked without it. Why tmux? Sessions survive disconnects - SSH drops, laptop sleeps, terminal crashes? Your work continues. Split panes - Editor on the left, tests on the right, logs at the bottom. Multiple windows - Like browser tabs for your terminal. Pair programming - Share a session with someone else in real-time. Scriptable - Automate your development environment setup.
