Lessons learned for GNU Screen

From personal usage

  • Ctrl-a:source properscreenrc : load the configuration file
    • pratical to avoid restarting a new session but appends other windows
      • can be problematic for numbers
  • Ctrl-a:number 1 : moves the current window to position 1
  • Ctrl-a+[, Ctrl-a+Ctrl-[, Ctrl-a+<ESC> : enters scrollback mode
  • split
    • Ctrl-a+|: vertical split
    • Ctrl-a+S: horizontal split
    • Ctrl-a+TAB: switching between splits
    • Ctrl-a+": select a window to display in the split
  • screen -X other : send the command other to the current screen
    • e.g. screen -X select reading; to jump to the window named "reading"
    • for example /exec screen -X other will switch to the other screen within irssi
  • Ctrl-a+c : create new window
  • Ctrl-a+a : switch to the last window
  • ~/.screenrc : configuration file holding the status line and other parameter
    • ability to set the status line, start multiple command at startup, etc
  • screen -x : connect to an existing screen from the same user, perfect for tutoring
    • has some sudo issues, have to connect directly from ssh

  • Ctrl-a+A : rename the current window
  • Ctrl-a+K : kill misbehaving programs
  • Ctrl-a+M : monitor activity in a window
    • see also monitoring by : "Use C-a M to start monitoring a window for activity. C-a _ monitors for 30 seconds of silence."

  • tmux enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

My notes on Tools gather what I know or want to know. Consequently they are not and will never be complete references. For this, official manuals and online communities provide much better answers.
