Just compared the man pages of cp of the three major Unix vendors (SunOS, HP-
UX, AIX). They're all different. If there is a standard, it's not implemented
very well accross different platforms.

Well, the only cp that can be installed on all of the above platforms is gcp
ok, granted BSD cp would be another option, but I doubt that there are
packages available for all those platforms), so if you want consistent
behaviour, install GNU cp (and its friends). That's what I do at work, where I
have to cope with a heterogenous environment consisting of HP-UX, Linux, SunOS
and Windows. Only by using the GNU variants of the Unix tools I can use our
self-written (shell) scripts on either platform.
So the question is: What's better, following an (eventually minimalistic)
standard or defining the standard yourself?
OTOH, a Linux-only user wont even care. He has gcp, that's his "standard".
