Well, if you use sub-shells....   :-)

Personally I've always thought that job control and sub-shells are more
or less archaic features when you have a window system (and _everyone_
has a window system, or at least a simulation of one: window(1) :-).

However iff you use the trick Korn suggested, and which I showed, then
you can safely export $ENV and then any interactive subshell you start
will indeed benefit from your personal customizations, while
non-interactive shells won't lead you into relying on features other
people's non-interactive shells don't have.
