• Definition: tmux (terminal multiplexer) is a command-line tool that allows users to run multiple terminal sessions within a single window, manage these sessions, and switch between them easily. It provides a way to keep terminal sessions running even when the user is disconnected.
• Function: Enhances productivity by enabling users to create, manage, and navigate multiple terminal sessions from a single interface.
• Components:

   * '''Sessions''': Independent workspaces that can contain multiple windows and panes.
   * '''Windows''': Containers within a session that can hold multiple panes.
   * '''Panes''': Split views within a window, allowing multiple command lines to be visible at once.
   * '''tmux Configuration File''': Customizable settings and key bindings defined in `~/.tmux.conf`.

• Features:

   * '''Session Persistence''': Keeps terminal sessions running even if the user disconnects or closes the terminal.
   * '''Multi-Window Management''': Allows multiple windows within a session, each with multiple panes.
   * '''Customizable Key Bindings''': Users can define custom key bindings to streamline their workflow.
   * '''Scripting and Automation''': Supports scripting for automating tasks within tmux sessions.
   * '''Remote Session Management''': Facilitates managing terminal sessions over remote connections.

• Starting a new tmux session:

   ```bash
   tmux new-session -s mysession
   ```
   This command creates a new session named `mysession`.

• Attaching to an existing session:

   ```bash
   tmux attach-session -t mysession
   ```
   This command attaches to the session named `mysession`.

• Creating a new window within a session:

   ```bash
   tmux new-window -n mywindow
   ```
   This command creates a new window named `mywindow` within the current session.

• Splitting a window into panes:

   ```bash
   tmux split-window -h
   ```
   This command splits the current window into two horizontal panes.

• Switching between panes:

   ```bash
   Ctrl+b o
   ```
   This key combination switches focus between panes.

• Sample .tmux.conf configuration:

   ```plaintext
   # Set prefix key to Ctrl+a
   set -g prefix C-a
   unbind C-b
   bind C-a send-prefix

 # Enable mouse support
 set -g mouse on

 # Set status bar color
 set -g status-bg colour235
 set -g status-fg colour136
 ```

• tmux: A powerful terminal multiplexer that allows users to manage multiple terminal sessions within a single window. It offers features such as session persistence, multi-window management, customizable key bindings, and remote session management, enhancing productivity and workflow in the command-line environment.

Snippet from Wikipedia: Tmux

tmux is an open-source terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time. It can also be used to detach processes from their controlling terminals, allowing remote sessions to remain active without being visible.
