Running Node (or any unix cmd line program) from Shell from a LC Stack

Yes - I think a 'login' type shell option would help here. (Which, if I recall correctly, causes the standard terminal setup scripts to run).

The reason the action of shell is to not use a login shell is because otherwise env vars you might want to pass to your new process might get clobbered by user settings which is (in general) probably not what you want.

For example if you set PATH temporarily to a specific folder to control the environment of your new process, it might be overridden by user settings causing breakage the other way. (Particularly if you need to use your own env vars which happened to also be set - for other reasons - in a user's shell environment).

The shell you get when you invoke the shell() command is a bit the same as the shell you get in the terminal prompt and a bit not. You're running into one of the nots.
