Recently, I learned a new feature of screen, it is referred as “multi display mode” in the manual. You can attach to a screen session that is not detached and the session is simply shared. In this mode, anything you typed are transferred simultaneously to the other display(s) as well. My mentor from my Google Summer of Code project used this feature to work collaboratively. In order to get in to multi display mode, you need to use “-x” parameter:

screen -x

If there are multiple sessions, you need to provide the session name as well:

screen -x session_name
