Write a shell script that removes files that contain a string

Deletes files in the current directory or its subdirectories that match "regexp" but handle directories, newlines, spaces, and other funky characters better than the original #13315. Also uses grep's "-q" to be quiet and quit at the first match, making this much faster. No need for awk either.
This is sample output - yours may be different.
3

find -type f -exec grep -q "regexp" {} \; -delete
