multi-pane terminal:

tmux is a terminal multiplexer. It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal.

• Ctrl + B + >: Open pane actions menu

Navigation:

• Ctrl + B + %: Split the current pane with a vertical line to create a horizontal layout
• Ctrl + B + ": Split the current with a horizontal line to create a vertical layout
• Ctrl + B + ➡️: Switch to pane to the direction (works with ⬅️➡️⬇️⬆️)
• Ctrl + B + z: Zoom the current pane (make it maximized or minimized)

Sessions: tmux starts a session that lives in the background like screen does. So if ssh deteaches, the session lives on until reboot or until it's killed.

• tmux new -s mysession: Allows naming a session -otherwise a random session name is generated.
• tmux ls: List sessions.
• tmux attach -t mysession: Reattach to session.
• tmux kill-session -t mysession: Clean up when done.
• Ctrl-B D: Manually detach from a running session.

Command Mode:

• Ctrl + B + :: Enter command mode.

Commands:

• :resize-pane -D|-U|-L|-R <number>: -D (down), -U (up), -L (left), or -R (right). <number> is the number of "cells" i.e. character grid rows/columns.
  • NOTE: To resize a pane in tmux, press Ctrl+b followed by Ctrl and the arrow keys to adjust the size by one cell.
