It'd pretty unlikely for that to be the case, but you'd be relying on the find command, the underlying readdir() system calls, etc. which just don't guarantee an order. So when handling needs to be done in an order, ensuring that order via something like sort is the only sane way to script such a task. It's along the lines of the old saying "trust, but verify." :) -- Todd
