title: Trigger notification over SSH pipeline
body: <p>I have a question about SSH and notifications (or commands in general).</p>
  
  <p><strong>I have:</strong>
  1. my computer which is a macbook pro
  2. my server which is a Debian 9</p>
  
  <p><strong>On my server I have:</strong>
  1. Nodejs (npm, node, etc...)
  2. My web projects using node for build</p>
  
  <p><strong>What I want to do:</strong>
  1. Display a notification on my screen (my macbook pro) when a build is finished on my server</p>
  
  <p>Is their any possibility to execute some commands on my macbook from the server directly? I'm connected over SSH so invoking commands on my server from my macbook pro is easy, but the reverse...?</p>
  
  <p>Hope this is clear and that someone has an idea to help me..</p>
