I have a program running under screen. In fact, when I detach from the session and check netstat, I can see the program is still running (which is what I want):
udp 0 0 127.0.0.1:1720 0.0.0.0:* 3759/ruby
Now I want to reattach to the session running that process. So I start up a new terminal, and type screen -r
$ screen -r There are several suitable screens on: 5169.pts-2.teamviggy (05/31/2013 09:30:28 PM) (Detached) 4872.pts-2.teamviggy (05/31/2013 09:25:30 PM) (Detached) 4572.pts-2.teamviggy (05/31/2013 09:07:17 PM) (Detached) 4073.pts-2.teamviggy (05/31/2013 08:50:54 PM) (Detached) 3600.pts-2.teamviggy (05/31/2013 08:40:14 PM) (Detached) Type "screen [-d] -r [pid.]tty.host" to resume one of them.
But how do I know which one is the session running that process I created?
Now one of the documents I came across said:
"When you're using a window, type C-a A to give it a name. This name will be used in the window listing, and will help you remember what you're doing in each window when you start using a lot of windows."
The thing is when I am in a new screen session, I try to press control+a A and nothing happens.
