Tmux
Find my tmux config here and here all of my dotfiles
Why tmux#
- Multiple shell windows and panes from a single connection
- Session functionality that survives disconnects
- Session sharing
- Plugins extend functionality
- Keyboard driven
- Highly customizable
Alternative: screen which comes preinstalled on most distributions
Basic concepts#
