Having a terrible problem with quotes/single quotes!
Hello. I'm trying to write a bash script that uses GNU screen and have hit a brick wall that has cost me many hours... (I'm sure it has something to do with quoting/globbing, which is why I post it here)

test.sh:
A simple `screen -r blah` will show it worked well! I have a pretty hardstatus line that shows the hostname, windownames, and dates.
Now I want to wrap the screen commands into a Launch command...
test2.sh:
if you do a `screen -r blah`now...
Most everything worked - it created the "blah" screen session, and even created the "dummy" and "dummy 2" windows.. But look at the status line, its just a blank white bar!
