title: grep command not found in adb shell
body: <p>After my phone is connected to the computer through adb, going to adb shell and then typing <code>grep</code> gives me  </p>
  
  <pre><code>grep: not found  
  </code></pre>
  
  <p>Is this a problem with my adb installation or my phone? How do I get grep to work for my device?  </p>
  
  <p>PS: This is the reason why I think it might a problem with my phone (as opposed to the adb installation)<br>

  The answer says  </p>
  
  <blockquote>
    <p>The grep utility may not be installed on your device.  </p>
  </blockquote>
  
  <p>However, I may have misunderstood the statement. How do I get grep working?</p>
