Sure, but the problem with all these is that one doesn't get usable
per-operand totals - only one big overall total.

If you take e.g.:


find dir1 dir2 fileA -not -type d -print0 | du -hsc --files0-from=-

(without the tail), one get's one line per (non-directory) file below
dir1 and dir2 as well as one for fileA .. plus the grand overall total,
whereas it would be nice to have totals for:
- dir1
- dir2
- fielA
- overall

Cheers,
Chris.
