title: shelljs: shx can't work correctly
body: <p>I am working in windows platform, and want to use some Unix shell command in daily work.So I install the shelljs package via node as following:</p>
  
  <pre><code>npm install -g shelljs
  </code></pre>
  
  <p>the installation runs well. But I can't use the shx as interface to run Unix shell. The error message said "it is not recognized as an internal or external command".</p>
  
  <p>So how to fix the issue?</p>
  
  <p>Edit:
  Find the reason, it turns out there is another node package named <code>shx</code>. The difference between <code>shelljs</code> and <code>shx</code> is:<br></p>
  
  <ul>
  <li>ShellJS: Good for writing long scripts, all in JS, running via NodeJS
  (e.g. node myScript.js).</li>
  <li>shx: Good for writing one-off commands in npm package scripts (e.g.
  "clean": "shx rm -rf out/").</li>
  </ul>
  
  <p>so install shx is the correct move I need to make. </p>
