Introduction
tmux (terminal multiplexer) is a powerful terminal tool that allows you to manage multiple sessions, windows, and panes within a single terminal window. Whether you’re doing remote development, server management, or daily terminal operations, tmux can greatly enhance your efficiency.

Basic Concepts
- Session: The top-level container in tmux. A session can contain multiple windows.
