    What if any of those dirs has funky chars in its name (path) ? (hint: IFS) Commented Mar 15, 2016 at 23:57
  • @don_crissti The script would fail. Don't put funky chars in your filenames, children! Although, any whitespace would also fail the script. That's a good point. Commented Mar 16, 2016 at 0:01

    That's still pretty bad. Avoid the for f in $(find...) construct. find is a robust tool and you can do this find-only in a reliable manner. Commented Mar 16, 2016 at 0:15
  • Better than fiddling with IFS, you should just avoid the split+glob operator. There are robust ways to do it, why insist on fragile ways? Commented Mar 16, 2016 at 0:25
  • It's just one way to do it. There are other ways that I haven't done before. In fact, this is the way I would have done it before I learned about these things in find. Commented Mar 16, 2016 at 0:27
