# A CLI Script to update list of domains instead from the UI. Can be useful for people who want to execute updates from a cronjob
#
# Tip:
# When running from a cron, use flock (you might need to install it) to be sure only one process is running a time. eg:
# */5 * * * * flock -xn "/tmp/pdns-update-zones.lock" python /var/www/html/apps/poweradmin/update_zones.py >/dev/null 2>&1
