title: Linux - How to show a text message to a particular user during user login
body: <p>I have a text file in <code>/opt</code> which I would like to display to a particular user (e.g.: <code>/home/sunil</code>) during login (similar to welcome message).</p>
  
  <p>I know about <code>/etc/motd</code> which displays the message for all users during login.</p>
  
  <p>I don't want to use the respective users' <code>.cshrc</code>, <code>.bashrc</code> or <code>.profile</code> etc. because users will be added and deleted constantly.</p>
  
  <p>Is it possible to display text to a particular user during login?</p>
