title: How to update grunt devDependencies?
body: <p>I am relatively new to grunt and am not really familiar with node yet. </p>
  
  <p>I have a boilerplate <strong>Gruntfile</strong> and <strong>package.json</strong> file that I use in all my projects and modify it as needed. </p>
  
  <p>When I start each project I want to update all the Grunt plugins in devDependencies and the package.json, but I don't know of a quick and easy way to do this. </p>
  
  <p>Is it possible to update all modules with one command or do I have to do them individually?</p>
  
  <p>Thanks.</p>
