@arubislander OK, thank you, I'll have a look at it and consider this option. Cheers

What does exacly exec do?

I ask, because sh doesn't work for my script like . does.

I'm also interested as I want to run VPN on boot and keep it always on.

Here are my scrips and other information.

Also, what are the nmcli commands that enable cellular data? I tried to find it and I'm run out of ideas.
