I'm no Guru but if you save the output into a file named "rip.me"
Code:
sed 's/\([a-z]_[a-z]*\).*/\1/' rip.me
Will give you the first column. Tinker with it from there,
I imagine somebody will be along shortly to show us a really clean way to do this.
By the way, that's much easier to do with awk than sed
