What is tmux?

tmux, short for terminal multiplexer, is a powerful command-line utility that allows users to manage multiple terminal sessions from a single window. It provides a way to switch between several programs in one terminal, detach them, and reattach them to another terminal without disrupting the running processes.

Key features of tmux include:

• Session Management: Create and manage multiple sessions.
• Window Management: Split a single session into multiple panes or windows.
• Detach and Reattach: Detach a session and reattach it later from the same or a different terminal.
• Persistent Sessions: Keep your sessions running in the background even if you disconnect.

When to Use tmux?

tmux is incredibly useful in a variety of scenarios:

• Remote Work: When working on a remote server via SSH, tmux allows you to maintain persistent sessions. If your SSH connection drops, you can reconnect and resume your work without losing your session.
• Multitasking: If you frequently need to switch between multiple command-line tasks, tmux provides a convenient way to manage multiple windows and panes within a single terminal session.
• Long-Running Processes: Running long processes such as compiling code or data processing can be done in a detached tmux session, allowing you to log out and log back in later to check progress.
• Development: Developers often need to run multiple commands simultaneously (e.g., running a server, watching file changes, running tests). tmux helps manage these tasks efficiently.
• System Administration: System administrators can benefit from using tmux to monitor logs, run scripts, and manage multiple SSH sessions from a single interface.
