TMUX: Terminal Multiplexer

TMUX is a powerful tool that allows you to manage multiple terminal sessions within a single window. This guide covers the basics and some customization tips to enhance your terminal experience.

Getting Started

Installation

On Debian-based systems, you can install tmux using:

sudo apt install tmux

Basic Usage

1. Start a new session:

   tmux

2. The Prefix Key:

   • TMUX uses a prefix key to distinguish its commands from regular terminal input.
   • The default prefix is Ctrl+b. Press this before any TMUX command.

3. Detach from a session:

   • Press the prefix, then d

4. List all sessions:

   tmux list-sessions

   • Or use the shortcut: prefix + s

5. Attach to a session:

   tmux attach -t [session-name]
   # Shorthand version:
   tmux a -t [session-name]

   • To attach to the most recent session:

     tmux a

6. Rename a session:

   • prefix + $

Managing Panes and Windows

Panes

• Split vertically: prefix + %

• Split horizontally: prefix + "

• Navigate panes: prefix + arrow keys

• Close a pane:

  • Type exit or
  • prefix + x

Windows

• Create a new window: prefix + c
• Navigate windows:
  • Previous: prefix + p
  • Next: prefix + n
• Close a window: prefix + &
• Rename a window: prefix + ,

Customization

While TMUX works great out of the box, customizing it can improve your workflow and aesthetics.

1. Create a config file:

   nano ~/.tmux.conf

2. Example customizations:

   # Use C-j and C-f as prefix keys
   set-option -g prefix C-j
   set-option -g prefix2 C-f
   
   # Easier window splitting
   bind-key v split-window -h
   bind-key h split-window -v

Remember, the beauty of TMUX lies in its flexibility. Experiment with different settings to find what works best for you. Happy multiplexing!
