title: Finding all files with certain extension in Unix?
body: <p>I have a file <code>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home</code></p>
  
  <p>I am trying to find if I have the *.jdk anywhere else on my hard drive. So I do a search command:</p>
  
  <pre><code>find . -name "*.jdk"
  </code></pre>
  
  <p>But it doesn't find anything. Not even the one I know that I have. How come? </p>
