I'll bet there's a shorter AWK version though.

I have files with the following structure:
garbage

output start
.. good data
.. good data
.. good data
.. good data
output end
garbage

How can I extract the good data from the file trimming the garbage
from the beginning and end?
The following works just fine but it's dirty because I don't like the
fact that I have to pick an arbitrarily large number for the "before"
and "after" values.
grep -A 999999 "output start" <infile> | grep -B 999999 "output end" > newfile
Can anyone come up with something more elegant?
