title: Is there any difference between start appium server via appium & command or using just appium
body: <p>I can start the appium server via command line using below commands via command line since I installed the appium using npm.</p>
  
  <pre><code>   appium &amp;
     appium
  
  //To change the default port 
  appium &amp; --port 9090 
  appium  --port 9090 
  </code></pre>
  
  <p>As I observed both commands are doing the same, so are they identical or is there any difference?</p>
