As far as I understand the man page, --aparent-size returns the size of
the file(s), whereas without --aparent-size the size allocated on disk
is returned. See the following example:

[juri@kaplah juri]$ echo "foo" > bar
[juri@kaplah juri]$ du -sh bar
4.0K bar
[juri@kaplah juri]$ du -sB1 bar
4096 bar
[juri@kaplah juri]$ du -sb bar
4 bar
[juri@kaplah juri]$

Cheers,
Juri
