Little bash script to repeatedly check if any appointment slot is available for Anmeldung (apartment registration) in Berlin

anmeldung-termin-notifier.sh

#!/bin/bash

# Check if xidell is present (required for extracting from webpage using xpath)
if ! command -v xidel &> /dev/null
then
    printf "\n\nCould not find xidel \n\n"
    echo "You can install it with (on a mac):"
    echo "brew install xidel"
    exit
fi

FULL_URL=$(xidel --silent https://service.berlin.de/dienstleistung/120686/ --extract '//*[@id="top"]/div[2]/div/div/div/div[4]/div[4]/div[1]/div/div[2]/div/a/@href')
DELAY_SEC=600

PATTERN="An diesem Tag einen Termin buchen"

function show_notification {
  # Show notification on macOS when osascript is present, otherwise print to console
  if ! command -v osascript &> /dev/null
  then
    osascript -e 'display notification "Termin slot available for Anmeldung!"'
  else
    echo "Termin slot available for Anmeldung!"
  fi

}

while true
do
  slot_exists=$(wget "${FULL_URL}" -qO- | grep -c "${PATTERN}")
  [[ $slot_exists -gt 0 ]] && show_notification && echo "$(date):    $slot_exists slots available now!"
  sleep ${DELAY_SEC}
done

Just realised, they changed the website, sucks... why is so hard to get an appointment here!

I made a version without xidel inspired by this script. Star if it helps you :) https://github.com/nwehrhan/berlin
