title: how to recreate npm links to executables
body: <p>I am new to npm and nodejs. I installed nodejs 9 and I created my first npm build app.</p>
  
  <p>I noticed the <code>prefix</code> of npm was <code>/usr</code> and I changed it to <code>/usr/local/npm-global</code></p>
  
  <p>I moved the old packages to the new location. I wanted to recreate the symbolic links. How do i do that?</p>
  
  <p>I checked <code>bin</code>, <code>link</code> and <code>rebuild</code> commands but the don't seem to be what I'm looking for. </p>
