* Reproduction
1. Run MacOS (Or I suspect any OS that is not GNU-based).
2. emacs -Q
3. M-x package-install RET dired-du RET
4. M-x dired RET ~ RET
5. M-x dired-du-mode RET
6. Notice that file sizes are displayed in kbytes, not bytes (they are =
displayed in bytes in a GNU-based system)
7. M-x dired-du--toggle-human-readable RET
8. M-x z z (to enable file sizes displated in human readable form, i.e. =
sizes ending in k, M, G, T)
9. File sizes displayed are one order of magnitude smaller than their =
actual size (e.g. if the file size is 2MB then it will be displayed as =
2kB)

* Discussion
The problem seems to arise when the custom variable =
dired-du-used-space-program is set. For a GNU-based system, it gets set =
to "du -sb" but for MacOS it gets set to "du -sk". Then later when the =
human readable sizes are calculated, this difference does not appear to =
be accounted for.

Why do we make the distinction between a GNU-based system and anything =
else? Can we just change the logic setting dired-du-used-space-program =
to always run "du -sb=E2=80=9D?

Cheers,
Matt

P.S. This is my first Emacs bug report so please help me out if I should =
report it differently.=

$ uname -a
Darwin rpluim-mac 18.2.0 Darwin Kernel Version 18.2.0: Fri Oct  5 19:41:49 =
PDT 2018; root:xnu-4903.221.2~2/RELEASE_X86_64 x86_64
$ du -sb
du: illegal option -- b
usage: du [-H | -L | -P] [-a | -s | -d depth] [-c] [-h | -k | -m | -g]
[-x] [-I mask] [file ...]

IOW the fix will have to be in dired-du.

Hmm, right you are. I forgot that I had GNU core utils installed on my =
Mac.

I suggest two things:
1. Look for gdu in path and use that if possible.
2. Add something like `dired-du-used-space-units` to indicate whether =
file sizes are stored in bytes, kilobytes, whatever. Then modify =
`dired-du-count-sizes` to multiply appropriately.

I can submit a patch if you think that=E2=80=99s the way to go.

By the way, I just want to verify: Is this the right place to submit a =
bug report for dired-du?=
