title: Executing System Commands with Rails
body: <p>I am executing some system commands based on user actions such a <code>mkdir</code>,<code>cd</code>, <code>cp -r skel/ dest/</code>, and creating an apache vhost etc. </p>
  
  <p>Where is the best place for this code to live? My instinct is to put them in the model as private methods, is this correct?</p>
  
  <p>Thx</p>
