I don't think it's possible for this to happen.

Your subject line suggests that you've done a fair amount of browsing. Thus,
you know what the terms 'parent' and 'child' refer to.

As far as I know, while a 'child' can inherit a 'parent' environment, there
is no official path for doing the opposite.

There may well be an unofficial path, something involving breaking through
the protections imposed by UNIX ... but it would be much simpler to make an
alias, seeing as you're working with a csh, wouldn't it ?
