Login to Facebook using cURL

facebook-login.sh

#!/bin/sh

# Authenticate an facebook application directly from shell.
# Make sure to modify the EMAIL and PASS below and just run it as:
# sh facebook-login.sh "<your facebook url>"
#
# It's possible to script and run the script in a while loop (In my case this is necessary hence
# the facebook-sdk api for php causes random crashes and my script needs to run for a loooong time.
