Let me see...
Hmmm, sure looks like that could be somewhat equivalent to ls...
cat foo > bar
Heck, that works almost the same as cp!
mv foo bar
Well, foo didn't disappear, but there is no foo anymore.
cat > foo
A usable substitute for an editor if what I'm creating is very small and
cp foo bar; rm foo
That looked almost like a mv.
mount myothermachine:/foo /mnt
cp /mnt/bar .
Hey, they seem to result in the same thing. Imagine that.
I can probably go on for a while longer, but I *hope* you get the point
this time. I have been forced to do things this way sometimes, when things
turned bad (on a few occasions, cp on NetBSD/vax have been known to stop
working because some mmap problem).

That is also an option. But /rescue is rather vulnerable, plus I probably
don't even know if it works until the day I'm going to use it.
