title: /bin/sh^M: bad interpreter: No such file or directory
body: <p>When I enter <code>brew doctor</code> (or any <code>brew</code> command) in my terminal, I get this as a response:</p>
  
  <blockquote>
    <p>-bash: /usr/local/bin/brew: /bin/sh^M: bad interpreter: No such file or directory</p>
  </blockquote>
  
  <p>I have seen the <code>^M</code> response before and I think it has to do with dos line ending files. Is there a way to fix this? </p>
