title: Is there any functional difference between .bashrc and .bash_rc?
body: <p>Is there any difference (functionality) between <code>.bashrc</code> and <code>.bash_rc</code> other than the underscore in the filename? Most of the webpages that I visit say <code>.bashrc</code> but the file in my Mac happens to be named <code>.bash_rc</code>. (I did create the file but I forgot the origin).</p>
