Oh, you've been famous for a while here.  :-)

This only returns the totals for mount points, however.  Not what I was looking 
for.

You are more adept at understanding man pages than I.  I didn't "get" the -s 
switch.  However, it only returns the single file or directory that I specify. 
It's closer to what I wanted than df but not quite there.

Yes, and I've concluded that's probably the only way I'm going to get what I 
want.

Nope.  You understood.

Thanks to everyone that responded.  I'll tweak the suggestions until I get what 
I want or some near equivalent of it.
