Even the busybox port has it. The only sort implementation I know of that doesn't have -h is toybox (I guess older busybox implementations are missing it as well), but I'm using -h for well over a decade and seldom had it missing

[out-of-ideas]

i was actually curious when busybox's sort added it; but didnt search too hard. was certainly easy to see gnu get it in 2009 i think (but even then if the dude setup there bashrc long ago and that func/alias works, likely no reason to change it immediatly)

i can say an `BusyBox v1.35.0 (2022-08-01 15:14:44 UTC)` did not have -h; so it having it now is kind of a shock to me (looks like busybox v1.36.1 has it - at least from 2023-06-22) - good too! always frustrating when a dev tries using gnu-args and it blows up and i gotta explain the diff between mac-shell-cmds, gnu, and busybox
