💡 Tips

  • tmux sessions survive SSH disconnects — reattach with tmux attach after reconnecting, essential for remote development.
  • Ctrl+b is the default prefix key — change it to Ctrl+a in .tmux.conf if it conflicts with terminal shortcuts.
  • Text selected in copy mode goes to the tmux buffer — extra configuration is needed to sync with the system clipboard.
