I was looking at this method as well. I was having trouble though as I
know the left hand side column so for this example the Compression
portion then the colon : the remainder could be anything for instance
a description with lots of text and could also contain a additional
colon.  At the shell prompt I could grep "Compression" | cut -d: -f2-
and that would grab everything...
So it sounds like I'm looking in the correct area but Im just not
pulling it all together. I will keep at it if you have additional info
to point to that would be great..and appreciated.
 Thanks again.
