title: Mysterious phantom rm -i alias
body: <p>I'm using zsh on Mac OS 10.6.8.</p>
  
  <p>So, all of a sudden one of my machines asks me for confirmation every time I rm.</p>
  
  <p>Frankly, I hate this with an abiding passion. I've never had a problem with rm, and I don't need to debate the potentialities. </p>
  
  <p>First thing I did was <code>which rm</code>, which reports <code>rm: aliased to rm -i</code>.</p>
  
  <p>Now, I've hunted high and low for this alias. zshrc, .config (which I don't have), the default zshrc files: everywhere I can think of. No mention of aliasing rm anywhere.</p>
  
  <p>Is there a simple way to determine where this alias is being configured? Or to list all locations where zsh might be looking for config lines?</p>
