Question: I started a VPN connection with `sudo openvpn --daemon --config connection.ovpn`. Is there a way to terminate this connection without using `ps` to search for the process and then `kill` it myself?

Answer: 
No, you will need to kill the process. In fairness a daemon management script would do just that. You can use pgrep or pkill to make your life easier.
```
sudo openvpn3 session-manage --disconnect --config $'client'.ovpn

```

Replace client with the corresponding name.
This will shutdown the session.
