title: Best way to handle objects property:value in the stdin in bash
body: <p>Bonjour, </p>
  
  <p>I launch <code>nslookup someServer</code>.  I consider I get a serie of object (as in powers hell) separated by empty lines and not simply a stdout.</p>
  
  <pre><code>$ nslookup someServer
  Server:      10.0.0.1
  Address:     10.0.0.1#53
  
  Name: someServer
  Address: 10.0.0.5
  
  $
  </code></pre>
  
  <p>How to get the object who have both properties Name and Address?</p>
  
  <pre><code>nslookup someServer | haveboth Name Address | wc -l 
  </code></pre>
  
  <p>Does it exists in GNU utilities?</p>
