title: find and remove multiple file using linux command
body: <p>I have a directory named <code>classes</code> which contains a lot of sub-directories - </p>
  
  <pre><code>classes  
    |-security  
    |-registration  
    |-service  
   ....  
  </code></pre>
  
  <p>Each of these directory contains a lot of <code>java</code> files and their compiled classes files. I want to remove all the class file.  </p>
  
  <p>Going to <code>classes</code> directory I can list out all the class file using find command -  </p>
  
  <pre><code>$ find . -name *.class  
  </code></pre>
  
  <p>Is there any command in linux to remove all the classes file under the <code>classes</code> directory. </p>
