tmux
Some basics about tmux (terminal multiplexer), a command-line tool that lets you manage multiple terminal sessions from a single window.
You can...
- split your terminal into multiple panes (either horizontally or vertically).
- run multiple programs (like shells, editors, logs, etc.) side-by-side in the same terminal.
- detach from a tmux session (leave it running in the background), then reattach later—even after disconnecting from SSH.
- have multiple windows within a session, each with its own set of panes.
Default Prefix Key: Ctrl+b (press this, then the next key)
