title: How to match double quotes using grep
body: <p>I thought I knew this(or at least how to google for it)! </p>
  
  <p>But I can't figure out how to match double quotes using grep when searching for patterns in text file. I tried to escape the double quotes symbol with a backslash, but it doesn't seem to work.</p>
  
  <pre><code>&gt;cat trial.txt  
  "Bill" is here and "Ben" is there
  
  &gt; grep -iE "and \"ben\" is" trial.txt
  Unmatched ".
  </code></pre>
  
  <p>How do I get this to work?</p>
