title: How to match double quotes using sed
body: <p>How can I make sed use double quotes (<code>"</code>) as a match?</p>
  
  <p>I try to replace <code>"source/design</code> to <code>"source/design_new</code> only without changing the second coding.</p>
  
  <p>Input:  </p>
  
  <pre><code>"source/design",  
  "include/source/design",
  </code></pre>
  
  <p>Expect Output:  </p>
  
  <pre><code>"source/design_new",    #only this line renaming  
  "include/source/design"
  </code></pre>
  
  <p>I tried with command: </p>
  
  <pre><code>sed "s/\"source\/design/\"source\/design_new/g"
  </code></pre>
  
  <p>but it is complaining with an <code>unmatched "</code> error. Is there any way to use double quotes in <code>sed</code>?</p>
