tmux

Tutorial

sudo apt install tmux  # on Ubuntu

Three different ways to trigger a tmux command:

1. tmux <COMMAND> # via tmux program
2. (C-b) :<COMMAND> # tmux command window
3. (C-b <HOTKEY>) # tmux command hotkey/keybinding

Working with sessions (equivalent to a single desktop environment):

• Start a new session: tmux (new command)
• See all keybindings: C-b ?
• Detach session: C-b d (detach)
• Attach session: tmux attach
• List sessions: tmux ls
• Kill session: tmux kill-session / tmux kill-server

Working with windows (equivalent to individual program windows in DE):

• Create new window: C-b c (neww)
• Change windows: C-b 0 / C-b 1 / ... / C-b l (last window)
• Kill window: C-b &

Working with panes:

• Split window into panes: C-b % or C-b " (split-window)
• Change panes: C-b Up / C-b Down / ...
• Move panes: C-b { / C-b }
• Tile panes: C-b M-5 (e.g. for even tiling)
• Kill pane: C-b x

Enable mouse support with :set -g mouse on. Some things one can do:

• Left-click pane to set as active
• Left-click drag pane borders to adjust
• Right-click pane for context menu
• Left-click window title to set as active
• Left-click drag pane text to copy (C-b ] to paste)

Configure tmux server with config file at ~/.tmux.conf.
