title: Best way to find the numeric value in UNIX file system
body: <p>I need to grep for a particular port number from a huge set of files.</p>
  
  <p>I am using a command:</p>
  
  <pre><code>find . |xargs grep "9461"
  </code></pre>
  
  <p>But it does not finds all the occurrences for number 9461.
  Can anyone suggest a better unix/linux command to do so.</p>
  
  <p>The kind of files it gets is : <code>x.log</code>, <code>y.txt</code>,<code>z.htm</code>, <code>a.out</code> etc files
  But it was not able to get <code>abc.conf</code> files</p>
