It's also a shell that runs on VMS.  Does that make VMS Unix?

Only if you su to root and root has the "#" set as his prompt.  If you
su to any other user you will get whatever they have as their prompt.

Nobody said that.  But you obviously have no idea what su actually does.

Why?  I am a regular user and my prompt is a "#".

So, what do you think the su command really does?

Huh?  What are you talking about.  In one case it's output and in the
other it's input.  And in both cases it is shell.

Who ever said it was?  And what does that have to do with the prompt
output by the shell?

And that statement makes as much sense as anything you have said about
Unix. You really should stick to VMS.
