You can use the `command` command to determine which `which` you use ;) % which which which: shell built-in command % command which which /run/current-system/sw/bin/which I like to use `which` together with `realpath` to see what exact version of a program I'm using, e.g. (in Fish), [I] ⋊> ~ realpath (command which which) /nix/store/3w3rvxhlv5dcmdih72da6m613qyav9kw-which-2.21/bin/which Idk if it's also POSIX, but `co…

When I read stuff like this I can't help but wonder how anything ever even gets done on this project. The amazing thing is 'which' was working perfectly fine for everyone. Just leave it alone? The amount of time they wasted on debating this is staggering compared to just not changing it.

And yet they destabilized things by adding the deprecation/trying to get rid of it. And what even was the point of that?
