That won't work with spaces in filenames. :) "find … -exec" or "find …
-print0 | xargs -0" are the best ways to do this. Apart from "find …
-delete" which I regularly forget. :)
Actually, that *will* work with spaces in the filenames[1], since the shell
built-in read doesn't stop until end of line. There are some other, even less
common, characters that can confuse read though: '\', '"', and NL.
[1] At least with single space characters. Read might be sensitive to IFS/OFS
and merge runs of characters or translate all whitespace to space characters;
I'm not looking at the spec right now.
There might be some ppl finding this interesting:

2, 3, bar foo

a b

eris:~# while IFS= read -r; do echo "$REPLY"; done < /tmp/tst
1, 2, foo bar
