I've done this before with awk, but with "find ... -ls". I don't know why you want to use du with xargs (is it really to get du's measure of bytes rather than the stat's count, for when they are different?) -- as that's calling over a thousand du's to walk the linux tree, when find can print bytes built-in with -ls (much more efficient).
