I would just like to point out that on most unix systems, mv is also
simply a link to cp and ln. It could have been implemented this way
on the UNIX-PC also, but the implementers chose to give us two
identical programs in /bin. One is the linked cp and ln, the other
is mv. They are byte for byte identical. The only difference
is the permissions. Mv is set uid'ed.
If space becomes a premium on the floppy, a few blocks could be saved
by linking mv to cp and ln, then changing permissions on them to
match /bin/mv on the HD (4755, root owner).
