I used real files (already sorted) to test whether having -s or not affect -m. But I have not made minimal example input files so that is why I am not sure about my conclusion.
But the command to try is basically `sort -m -k sort_fields files...` or `sort -s -m -k sort_fields files..`. I assume to authors who made -m and -s. My question should be clear?
