There shouldn't be, so you should be okay there.  But people rarely
leave things alone.  If you mutated that into a few close variations
you could end up a problem.  So I was warning about it as a
precaution.  For example if you added the -l option to exec.  Or other
things.

In the spare terminal I would move the .bash_profile and/or .bashrc
out of the way.  Rename them to different names.  That would stop any
of the problems I cautioned about.  Then you could debug what was
wrong and make another attempt.

I don't think PATH should be modified in the .bashrc.  It is read by
every shell.  Every time you would be adding to PATH.  Better to do it
once only in the .bash_profile only.

Sorry but I don't know anything about bashdb in Emacs.  But you
probably need to load the bashdb.el file first.  Probably something
like this in your .emacs file.

  (autoload 'bashdb "bashdb" "Run bashdb" t nil)

Find the bashdb.el file and read it.  There should be comments at the
top that inform how to use it.
