Tmux is a terminal multiplexing software that allows users to access multiple terminal sessions within a single window. It is similar to GNU Screen, but from OpenBSD and licensed by BSD. Tmux is a powerful tool for system administrators and developers who need to work on multiple tasks simultaneously.
Tmux offers many features that make it a popular choice for managing multiple terminal sessions. Here are some of the most useful features:
- Sessions: Tmux allows users to create multiple sessions, each containing one or more windows. A session is like a container for windows, and each window is like a tab in a web browser.
- Windows: Tmux windows are similar to tabs in a web browser. Each window contains a single shell prompt, and users can switch between windows using keyboard shortcuts.
- Panes: Tmux panes allow users to split a window into multiple panes, each containing a separate shell prompt. This feature is particularly useful for working on multiple tasks simultaneously.
- Detaching and attaching: Tmux allows users to detach from a session and reattach to it later. This means that users can continue working on a task even if they need to log out or shut down their computer.
Here are some examples of how to use Tmux:
- To start a new session, type
tmux new-sessionin the terminal.
- To create a new window, press
- To split a window into panes, press
Ctrl-b %(for a vertical split) or
Ctrl-b "(for a horizontal split).
- To detach from a session, press
- To reattach to a session, type
