A personal bash script I'm using to monitor when planning for "remises de titres de séjours" are ready at Bobigny prefecture. To avoid ban, spinning several few Amazon EC2 Paris microinstances is recommended

Bob.sh

#!/bin/bash -e

###
### This script is a continuation of vadimkantorov/rdv.sh
### https://gist.github.com/vadimkantorov/c6942cc702cceec7ffb30a990c72df5e
### This script is a helper to notify you when a planning for inscription
### to the prefecture to get back your card.
