What about this one simple command which not just finds but clears the nasty BOM? 🙂
find . -type f -exec sed '1s/^\xEF\xBB\xBF//' -i {} \;
I love “find” 🙂
Warning The above will modify binary files which contain those three characters.
If you want just to show BOM files, use this one:
grep -rl $'\xEF\xBB\xBF' .
