title: How to run a sudo command on startup?
body: <p>I'm trying to connect to my vpn on startup. I normally enter protonvpn c -f into command line.
  I have tried the method of creating an rc.local file however it didn't work.
  This is the code I have inside of it (I got this from a post about a similar issue):</p>
  
  <pre><code>#!/bin/sh -e
  /usr/local/bin/protonvpn c CH-NL#1
  exit 0
  </code></pre>
  
  <p>I also made the file executable with chmod +x.
  Im running Kali 2020.1 if that helps. 
  How do I fix this?</p>
