Are you sure it is BSD-derived? All the missing utilities that you cite
(and I found missing within about 5 minutes of using HP-UX) would point
to a SYS5 origin, with some BSD include files added. I can't believe
HP would deliberately remove things from a BSD port that did not impact
SYS5 compliance (like 'renice', 'msgs', 'talk', ...), or would they ???
"Official" comments, HP? If it is BSD-based, why not still provide the
BSD ps (and other) commands in another directory, which can be moved to
the head of the $path/$PATH for users who prefer BSD options?
