I understand the UNIX philosophy, but given the flexibility of the many and varied tools available on any/all Unix-like variants, I didn't think I'm asking for anything particularly out of the ordinary. Given that the facilities provided by /etc/security/limits.conf are very *close* to being what I want, it's not much of a technical/logical leap to what I was asking about. If it's truly not possible then, yes, I may need to rethink. Dave. -- Please don't CC me on list messages! ...
