A Bash script to monitor "Echange d'un permis de conduire hors Union Européenne" rendez-vous availability at Prefecture de Paris

rdv_echange_permis_conduire_paris.sh

#! /bin/bash

#Usage:
# 1. Download the script to Home folder and open the Terminal
# 2. Put in your e-mail and SendGrid bearer token to get a notification of success
# 3. Open the Terminal and run the script: "$ bash ~/rdv_echange_permis_conduire_paris.sh"
# 4. Get your RDV! Right now the script will exit once it found a RDV available. It would dump the HTML of the page to "~/rdv_naturalisation_saint_denis.sh.html". Comment the line 38 to continue checking.

set -e

SENDGRID_BEARER_TOKEN='' # should start with "SG."
SENDGRID_EMAIL='' # put your e-mail here
TIMEOUT=30 # timeout between checks in seconds
