[Bug 2154042] Re: ls: files are not sorted in alphabetical order by default

[Finn Gärtner]

The --group-directories-first sorting issue is known and was reported
and fixed upstream: https://github.com/uutils/coreutils/issues/11997

LC_ALL=C /usr/bin/ls -hlF however seems to work fine for me and I can't
find other bug reports on Github for these flags. Could you give some
concrete examples of the incorrect sort order?

Title:
  ls: files are not sorted in alphabetical order by default

Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  Since upgrading from Noble 24.04 to Resolute 26.04, files and folders
  are not sorted in proper alphabetical order when running ls in Ptyxis.
  The sort order appears roughly alphabetical but with many exceptions,
  and there is no obvious pattern to explain the deviations. Casing does
  not appear to be a factor either.

  I tried switching locales but all of the following give incorrect sort
  results:

  LC_ALL=C /usr/bin/ls -hlF
  LC_ALL=C /usr/bin/ls -hlF --group-directories-first

  LC_ALL=en_US.UTF-8 /usr/bin/ls -hlF
  LC_ALL=en_US.UTF-8 /usr/bin/ls -hlF --group-directories-first

  Switching to gnuls restores proper alphabetical sorting.
