Thanks to Paul for answering, to HaJo for reminding me I asked when I 
should have been searching and to you, Robert, for adding the warning.

I tried it one time in a row, it did what I wanted and the only bad

It's not hard to understand that the system would soon grow weary of
". /.bash_profile" in a free-running loop!
