I think the "an exact problem" thing tends to be misleading for open ended issues like this.
The while loop works (and I have used it), but can be tremendously slow, depending on the command in question (and if you need xargs to break up the command line, there tends to be a lot of work that needs doing). And, generally speaking, this is solvable - but it's also a problem that should have been solved once and for all a long time ago. (And, by "solved" I mean that it should be straightforward to use the xargs with the unix "standard" where one line is one record - here, a record being a file name.) Anyways, the -d option looks like it might be as good as it can get?
