$ LC_ALL=C du --help | grep -E -e 'apparent|sparse|fragmentation'
-------------------------------------------------------------------
--apparent-size print apparent sizes, rather than disk usage; although
the apparent size is usually smaller, it may be
larger due to holes in ('sparse') files, internal
fragmentation, indirect blocks, and the like
-b, --bytes equivalent to '--apparent-size --block-size=1'
