title: Git added files in ignore after I had done git add, now how to remove?
body: <p>I had ran git add . and then saw it was a huge file.
  I created a file .gitignore</p>
  <pre><code>/live-1
  /live/application/report_images
  /live/application/report_images_old
  /live/application/report_pdfs
  /live/application/order_pdfs
  /sig
  /live/notused
  </code></pre>
  <p>The problem is since the first add was made it's still tracking the files.
  I tried running (as recommended by SO)</p>
  <pre><code>git rm -r --cache .
  </code></pre>
  <p>But this hangs.
  Also tried individual directories like</p>
  <pre><code>git rm -r --cache live-1
  </code></pre>
  <p>This also hangs
  How can I force it to recognize the ignore files?</p>
