title: How to clean (delete) temporary files if they exist in Ubuntu OS?
body: <p>I need to do a lot of cleaning in my virtual machine whose operating system is Ubuntu.</p>
  
  <p>Normally in Windows, there is this kind of directory that contains temporary files and that should be cleaned:</p>
  
  <pre><code>C:\Documents and Settings\Administrator\Local Settings\Temp
  </code></pre>
  
  <p>Does it exist such a directory in Ubuntu? If yes, what is it?</p>
