Can I disable the IPython notebook to save the results into the ipynb file?

Question

I use the Jupyter 4.1.

I've found the results of the cells are also saved into the ipynb file. Can I disable it? I want manage it with Git.

For example, there is a cell of my notebook,

  {
   "cell_type": "code",
   "execution_count": 29,
   "metadata": {
    "autoscroll": "json-false",
    "collapsed": false,
    "ein.tags": [
     "worksheet-0"
    ],
    "slideshow": {
     "slide_type": "-"
    }
   },
   "outputs": [
    {
     "name": "stdout",
     "output_type": "stream",
     "text": [
      "2016-08-04 : 749591\n",
      "2016-08-05 : 447416\n",
      "2016-08-06 : 305969\n",
     ]
    }
   ],
   "source": [
    "curidx = (data.cur_day - data.start_day).days\n",
    "for iday in range(curidx, data.nday):\n",
    "     day = data.cur_day + dt.timedelta(iday - curidx)\n",
    "     print \"%s : %d\"%(day, int(pdata.barCn[iday]))\n"
    ]
   }

I don't want the contents of the outputs to be saved.

Thanks @Thomas K, guided by his advice, I've found the solution that is use the nbstripout. The usage is below

1. Install the nbstripout by pip.
2. cd to the dir of the notebook. If there is not a git repository, please init one.
3. Run nbstripout --install to install a git attribute filter which will strip out the outputs from the ipynb file when it's added to the git cache.
