EXACTLY !!
Make new commands, don't mess around with the old ones.
I agree that users need to be protected: Give them safer commands, Menu shells
or PullDown help screens, nurse them good, but don't take away the alertness
to the real thing - Unix is fast and dangerous, real progreammers reread their
"rm" statements twice !!
Don't let users expect that "rm -r *" will help them trim their filesystem
by asking them to confirm each file. Teach a user that, and watch his face
running on another system one day !!
B.T.W:
Think of the portability - 100.000+ shell scripts that needs to be rewritten.
We have enough trouble with differences between BSD and V, Csh, Bsh, Ksh etc.
as it is.
(Just my 2 cents opinion)
