I'm curious -- I thought "exec" was supposed to replace the currently
running executing image with the new image.

When I do an "exec" in "bash", it leaves the original bash.exe
in memory -- but only if the parent is at the top of its tree.

I.e. -- I can exec multiple bash's, but only the initial and the
newest child are kept -- intermediate generations exit.

So why the top level bash?  Is there anything the parent bash can
do that the child bash cannot?

Thanks,
-Linda
