How do I increase the scrollback buffer in a running screen session?

247

Lets say I have a currently running screen session I am interacting with through putty. I've realized that the scrollback buffer is too small and would like to increase it without starting a new screen session.

Is there a way to do this?

The man page explains that you can enter command line mode in a running session by typing Ctrl+A, :, then issuing the scrollback <num> command.

Press Ctrl-a then : and then type

scrollback 10000

to get a 10000 line buffer, for example.

You can also set the default number of scrollback lines by adding

defscrollback 10000

to your ~/.screenrc file.

To scroll (if your terminal doesn't allow you to by default), press Ctrl-a ESC and then scroll (with the usual Ctrl-f for next page or Ctrl-a for previous page, or just with your mouse wheel / two-fingers). To exit the scrolling mode, just press ESC.

Another tip: Ctrl-a i shows your current buffer setting.
