[solved] Where & what bash env file, Mac OS?

Hi!
I wanted to simplify my bash prompt, so I edited my etc/bashrc file. I thought this was the file that would override any other env files. When I opened it, I saw that the way it was setup was not what my prompt looked like, although I forget exactly what was there. But i edited it the way I wanted it

Code:

PS1="$ "

and saved it. I quit and restarted the Terminal, but my prompt hadn't changed. I looked at the environment and saw that the prompt was set entirely differently than what was originally in the /etc/bashrc file, or what I changed it to:

Code:

-bash $ env |grep PS
PS1=\s $

So I assumed it must be getting it's environmental variables from some other file. But I don't have any kind of bash files in my home dir, such as .bash_profile, (except .bash_history).
At this point I should mention that I'm using Mac OS 10.6, and the directory setup is a little different in some cases than standard unix.

My question is, where is bash ultimately getting its env variables from, and where might I find this file?

Also, is there a way to write directly to the bash environment from the terminal, such as when you add a directory to your PATH? If so, how should that look?
TIA!

Nevermind, it's the ~/.profile file.

libbash

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
