I've installed the Cloudflare gateway on Debian as a vm because I can't do
it directly in FreeBSD. But I want to be covered even when I use FreeBSD.
The script that I wrote forward the Cloudflare "VPN" from Debian to
FreeBSD,so from outside my IP will be cloudFlared.

What task is that?
Your answer does not help me to understand how to use a "structured
programming / if , while, for, functions" for the specific task that I want
to achieve. I failed using "your" lovely structured programming and that's
the reason why I'm asking for some hint to understand why and how I can use
it.

As others have noted, the above

That's not correct. There are many different GUI login setups where

That said, since
Should be as easy as executing the script from the .profile of root - that
