Use 'command -v' over 'which' to find a program's executable

One thing that came to me as news is that the command which—which is the de-facto tool to find the path of an executable—is not POSIX compliant. The recent Debian debacle¹ around which brought it to my attention. The POSIX-compliant way of finding an executable program is command -v, which is usually built into most of the shells.

So, instead of doing this:

which python3.12

Do this:

command -v which python3.12
