title: How do I change file permissions in Ubuntu
body: <p>In Ubuntu I want to change the file permissions of a whole folder and all its sub folders to read/write by anybody</p>
  
  <p>I have tried <code>sudo chmod 666 /var/www and sudo chmod 755 /var/www</code> without success</p>
  
  <p>update</p>
  
  <p>I have since found that changing privileges can also be done in the GUI by opening nautilus as sudo.</p>
