They're now obsolete. POSIX 1003.2-1992 marked them as "obsolescent",
and warned application writers to stop using them. POSIX 1003.1-2001
removed them. I guess they figured that 9 years' worth of "please
eat your broccoli" warnings was enough.

You're feeling old too? I recently dug out my Unix Version 7 manuals
to answer a question about "diff". I had more hair on the top of my
head when I first used "diff".
