title: Node Red - How to stop a Bash node with button
body: <p>I have a node Red Dashboard Button which starts a Bash node, Bash node executes a .sh script which lets a python file run. The python file runs in loop. </p>
  
  <p>I am trying to add a button which stops the Bash node without stopping the node-red instance. </p>
  
  <p>Does someone have an idea about how to do it?</p>
