dired-du-mode displays incorrect human readable file sizes for non-GNU systems Message-Id: <133EC18A-49D2-4665-9E31-ED25CDD8A7EF@HIDDEN> Date: Fri, 14 Dec 2018 22:37:33 -0800 To: bug-gnu-emacs@HIDDEN X-Mailer: Apple Mail (2.3445.101.1) X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.2.x-3.x [generic] [fuzzy] X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.6.x X-Received-From: 2001:4830:134:3::11 X-Spam-Score: -4.3 (----) X-Debbugs-Envelope-To: submit X-Mailman-Approved-At: Sat, 15 Dec 2018 02:34:54 -0500 X-BeenThere: debbugs-submit <at> debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: <debbugs-submit.debbugs.gnu.org> List-Unsubscribe: <https://debbugs.gnu.org/cgi-bin/mailman/options/debbugs-submit>, <mailto:debbugs-submit-request <at> debbugs.gnu.org?subject=unsubscribe> List-Archive: <https://debbugs.gnu.org/cgi-bin/mailman/private/debbugs-submit/> List-Post: <mailto:debbugs-submit <at> debbugs.gnu.org> List-Help: <mailto:debbugs-submit-request <at> debbugs.gnu.org?subject=help> List-Subscribe: <https://debbugs.gnu.org/cgi-bin/mailman/listinfo/debbugs-submit>, <mailto:debbugs-submit-request <at> debbugs.gnu.org?subject=subscribe> Errors-To: debbugs-submit-bounces <at> debbugs.gnu.org Sender: "Debbugs-submit" <debbugs-submit-bounces <at> debbugs.gnu.org> X-Spam-Score: -5.3 (-----) * 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.=
