title: Replace a javascript file on all websites in WHM
body: <p>I am having a serious issue. I need to replace a javascript file with a new one on all the websites in my WHM. I have almost 400 websites in my WHM and replacing it manually in every websites file manager is not possible.</p>
  
  <p>I have no idea if that is possible or not, or how is that possible.</p>
  
  <p>Is there a way to replace a particular js file with a new js file on all the websites in my WHM at one go through some shell script or any other way?</p>
