The result given by du -sh is accurate.

sharkdp commented 6 years ago

diskus is actually a replacement for du -sb. I should have been more precise in the README (I'm using it in the benchmarks, though).

You should get a similarly wrong value when you run du -sb from root. The problem is the /proc directory which does not hold any real files but reports a high "apparent size".

I think we could maybe also support "disk usage" instead of "apparent usage"/"file size".

Okay i understand :) Thanks for the precision.
