I am not sure I understand the ssh problem described here.

My understanding was that this is a problem with NON-interactive shells.

As long as you are willing to play games with wrappers and so on and
so forth, why not simply do:

	rsh foo 'rc -c ''. .rcrc; '$^cmd''''

Incidentally, a good way of getting an interactive shell to do something
just once, e.g., when starting a new xterm, is to set fn prompt as
follows:

	fn prompt {
		fn prompt 	# remove myself from the environment
		one-time init stuff
	}

This works differently from .rcrc because it could be, for example,
that your .xinitrc runs rc as a login shell, but only when a subshell
finally prints a prompt do you do things like set a terminal type, etc.

Byron.
