If not `LC_ALL=C` is set, the sort result is weird. Please inspect this sample code: cat <<EOF | sort --unique --debug a-ab aac a-ac EOF Running it with `LC_ALL=C` everything is fine: > sort: using simple byte comparison > a-ab > ____ > a-ac > ____ > aac > ___ > But switching to en_US.UTF-8 or de_DE.UTF-8 I got the broken result: > sort: using > a-ab > ____ > aac > ___ > a-ac > ____ > So any algorithm or script which depends on a stable sorted order will fail. As a mitigation I tried `LC_COLLATE=C` but still the ‘en_US.UTF-8’ sorting rules will be used :-/
