... If genie wanted to actually help, genie would have gone to the wiki and put all of their incredible knowledge there in a collaborative learning document where we can all benefit from it...
Or, he has a life (and a job) and doesn't have the time to be assed with trying to "think down" in order to teach others something that they could probably find, just as easily, on Google....

Edit: OK, here's my wiki submission (free of charge):
for file in *; do
sed -i -- 's/DASH/CROWN/g' "$file"
sed -i -- 's/Dash/Crown/g' "$file"
sed -i -- 's/DASh/CROWN/g' "$file"
done
seriously, is that all you can come up with.. then your really missing the point, and for that matter where the code came from..
