CLI tools/shell is attempting to follow more-or-less standardish
unix/linux setup but fails pretty hard, with many of the same commands existing but behaving
just differently enough to be annoying.
They wasn't following unix/Linux standards they are following unix/bsd standards. Standards that predate Linux and for some of us are very familiar indeed.
Everyone knows that macos (and windows) took a lot from unix/bsd. But that does not mean they are actively following any kind of reasonable modern standard. And saying they might be following some 30 year old supposed bsd standard is pretty hilarious for an OS that portends to be cutting-edge, intuitive and well-integrated.
