This has nothing to do with the C shell, as /bin/cp is an
external command (binary). :-)

I'd suggest using cpdup from the ports collection. It can
handle the described scenario very well (and flexible, if
required).

This is equivelant to cp -RpP: recursive, preserve certain
attributes, do not follow symlinks. See "man cp" for details.
Linux cp's -u (--update) does not have a direct equivalent.
Try cpdup. :-)
