You are right.

Don't regret.  I think I am doing the right thing.  As I've said
before what I tried first was admittedly a kludge solution.  I am done
with that and now exploring the correct unix way.  This is
experimental (shell is hard coded as "bash") however the mechanism
seems to be working.  I only need to add some more code to figure out
what the user's shell is.
