title: How to list all the Node.js modules I have linked with npm
body: <p>I am looking for a command that will list the names of global modules that I have <code>npm link</code>'d to local copies, also listing the local path.</p>
  <p>In fact, a list of <strong>all</strong> globally installed modules would be even better, with the <code>npm link</code>'d ones <strong>flagged</strong> somehow.</p>
