And when doing XP, there really is no maintenance
phase; it's all new development.

Hmmm, I had it in the version of Solaris I was using. 
I wonder if it was something extra our admins decided
to tag on, something your admins decided to remove (or
not install), or your version just didn't ship with

Not to shoot a bubble in your argument, Paul, but I've
used cut and ed at least once or twice in the last
couple of years.  But then, that is way more often
than the number of times I've had to contend with
renamed files.

I've never even heard of some of the other commands
you've listed.

In fact, I think diff3 is a more appropriate tool to
use than patch.  (diff3 is actually the reason I used
ed :-).
