Lessons learned for GNU Screen

From personal usage

• stuff in ~/.screenrc to append text in the selected window
  • e.g. stuff 'cd ~/MyPythonProject; workon MyPythonProject;'
• Ctrl-a:| for vertical split then Ctrl-a:TAB to switch
  • cf http://aperiodic.net/screen/quick_reference#split_screen
• 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
  • note that even if you do not need to copy, you can go see the history of your session including the result of your commands, extremely practical to compare outputs you didn't log
  • http://www.gnu.org/software/screen/manual/screen.html#Movement
• 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 Aperiodic.net : "Use C-a M to start monitoring a window for activity. C-a _ monitors for 30 seconds of silence."

    • For those confined to a hardware terminal, these commands provide a cut and paste facility more powerful than those provided by most windowing systems.

  • screen -raAD : connect to the current existing screen

• 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.
• neercs (including grabbing a process that you forgot to start inside neercs)

Note

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.
