[OS X Emacs] How to configure '~/.bash_profile' and '~/.bashrc' to work with Aquamacs?

[Christopher M. Balz]

A symlink from '~/.emacs_bash' to '~/.bash_profile' succeeded in getting '~/.bash_profile' to execute on Aquamacs, so that the shell buffers have some of the desired settings (aliases).


However, what is needed is to configure Aquamacs so that '~/.bash_profile' executes once per Aquamacs session, and '~/.bashrc' executes once per Aquamacs shell?  Otherwise, for example with a link from '~/.emacs_bash' to '~/.bash_profile', concatenated shell variables (commonly, $PATH) get a lot of redundant values in them.


On *nix and Cygwin-on-NT, GNU Emacs works out of the box with '.bash_profile' and '.bashrc' in the expected way: '.bash_profile' is executed once on the *nix system, and all shells, including Emacs shell buffers, get the variables from that. Likewise, '.bashrc' executes once per *nix shell, including for Emacs shell buffers.


Does anyone have any pointers to how to get Aquamacs to do the same?  Thank you in advance.
