I would avoid this method because it is extremely inefficient, especially with large files. Shell is very slow for loops like that because it is purely interpretive. If you wrote the same thing in Perl it would run way faster just because it does a compile on load. (Besides, you still have to show the 'find' invocation to run it recursively, as requested.) Steve's sed solution is probably not bad as well.
