  • Check out Gate number for your flight from CLI with Chrome, html2texgt and grep. Works on Arch Linux (Garuda) and probably will work on others. Requirements: * google chrome (might work with chromium as well) * installed html2text (on archlinux: sudo pacman -S python-html2text) * installed grep (comes by default with your OS) * the gate number should be visible at the given website (it's not existent too early before the flight and also disappears after the flight departed) Please don't forget to replace the link to appropriate one, matching your flight. You can also wrap this into something like `whlie true; do ...; sleep 60; done' and this will check and tell you the gate number maximum in 1 minute after it appears on Avinor website.
