Thanks for the report. However, you have hit a FAQ - sort order is locale dependent, and your system probably has a locale that chose case-insensitive collation. https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#Sort-does-not-sort-in-normal-order_0021 For a demonstration of how it matters: $ printf 'A\nb\nC\nd\n' | LC_ALL=en_US.utf-8 sort --debug sort: using ‘en_US.utf-8’ sorting rules A _ b _ C _ d _ $ printf 'A\nb\nC\nd\n' | LC_ALL=C sort --debug sort: using simple byte comparison A _ C _ b _ d _ As such, I'm closing this as not a bug, although you may feel free to add additional comments. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
