I want to run a shell script that might open my browser to a specific website. I don’t want the page to load when this happen. But I cannot switch off my internet access also (as I use the internet to remotely access another system at the same time). So I am planning to isolate the run time environment for the shell script.

I an on Arch and I used to use a AUR package called bubblejail to do this. But with the whole AUR security fiasco, I am not trusting any packages from AUR. I can switch to another distro if needed, like Rocky or something.

So my requirement is, Internet sandboxing for a terminal and the processes it spawns. Preferably using flatpak commands.

Edit: I tried disabling the internet usage for a terminal from Flathub using Flatseal. Sure I cannot curl after this, but when I launch my browser using it, it had Internet access.

    You said you don’t want the page to load. Do you even care if the browser opens?

    What about overriding the default browser application that the terminal tries to use? Maybe there’s some env variable to override the xdg browser default, and you could point it to a script that exits instantly.
