With find, -not is not portable, but ! is (suitably escaped when used in
an interactive shell); -path is not portable either.

POSIX find only allows you to use {} as a single argument IIRC; you can
just pass arguments to echo separately here: `-exec echo "{}" \\ \;'.

With sort, you should always normalize the locale, i.e.,
LC_ALL=C sort

Well, don't look at the GNU find(1) manpage if you're looking for
portable options only. That's what POSIX/SUSv3 is for; the findutils
info pages are more verbose about portability, too.
