How to view my custom VPN service listed in a terminal in order to export it?
Use networksetup or scutil
You can use it to at least establish/ disconnect connections to the VPN.
Use this command to connect the VPN configured with the name &quot;myVPN&quot;:
networksetup -connectpppoeservice &quot;myVPN&quot;

Disconnect from the VPN
networksetup -disconnectpppoeservice &quot;myVPN&quot;

When you want to check the connection status
networksetup -showpppoestatus &quot;myVPN&quot;


The &quot;system configuration utility&quot; or scutil command provides access to network configuration, too.
To connect to your VPN use this command:
scutil --nc start &quot;myVPN&quot;

Run the following command to disconnect from the VPN:
scutil --nc stop &quot;myVPN&quot;

If you want to check the connection status, use:
 scutil --nc status &quot;myVPN&quot;

Let's make it even better
Github Code
#!/bin/bash
#
# Provides some basic utilities for VPN connections.

readonly vpn=&quot;${2}&quot;

  echo &quot;$*&quot; &gt;&amp;2

  if [[ -z &quot;${cmd}&quot; ]]; then 
    err &quot;Command must be provided: [connect, disconnect, status, list]&quot;
    exit 1
  fi
}

validateVpnName() {
  if [[ -z &quot;${vpn}&quot; ]]; then 
    err &quot;VPN name must be provided as second argument&quot;
    exit 1
  fi
}

  networksetup -showpppoestatus &quot;${vpn}&quot; | grep -qv &quot;^connected$&quot;

Open the script in an editor and add this code. Let's say it's called vpnConnection.
Add #!/bin/bash so that it can start without further ado
echo `'#!/bin/bash'` &gt; ~/vpnConnection.sh &amp;&amp; chmod +x ~/vpnConnection.sh

./vpnConnection.sh list show all VPN connections
./vpnConnection.sh connect &quot;myVPN&quot; Connect to the VPN &quot;myVPN&quot; and automatically enter the password
./vpnConnection.sh disconnect &quot;myVPN&quot; disconnect the VPN &quot;myVPN&quot;
./vpnConnection.sh status &quot;myVPN&quot; view the connection status for VPN &quot;myVPN&quot;
