title: What is the difference between node vs nodejs command in terminal?
body: <p>I have untarred node.js from the tar file given on nodejs.org, but when i try executing my js program through node command nothing happens, but on the other hand nodejs command runs executes the file.</p>
  
  <p>So my question is what's the  <strong>difference between node command and nodejs command</strong> as and will it effect my programs as i <strong>didn't build from the source code.</strong> And i of that is the reason of this discrepancy.</p>
