screen

I frequently use screen when I log into the interactive nodes to a supercomputer that I have access to -- and I often run things and move on. There are about 20 separate nodes that I can log into; and if I check any one of them I'll have something like 4 detached sessions. Each of those sessions will have maybe 5 screen sessions within that.

Is there a quick way to cycle through all of these and close them down if they are not running any processes? My current process is to screen -ls and then screen -r #### then type exit until I'm back to the base screen.
