title: Unable to use unix shell commands in Jupyter notebook
body: <p>I have installed Jupyter notebook and python using Anaconda. However, I have a problem when I try running any UNIX shell commands like 'cat' for example. I get the following error</p>
  
  <pre><code>'cat' is not recognized as an internal or external command,
  operable program or batch file.
  </code></pre>
  
  <p>I tried re-installing Git and Anaconda but I still face the same issue. I am using Windows 10 by the way.</p>
