title: Run multiple files in terminal simultaneously
body: <p>I need to write a batch/script file that will run the following files:</p>
  
  <pre><code>server.js
  client.js
  </code></pre>
  
  <p>I want to run server.js only once but the client.js I want to run multiple times. I need the scripts to run simultaneously.</p>
  
  <p>Is it possible?</p>
