# pihole-cloudsync
# Helper script to keep multiple Pi-holes' lists synchronized via Git
# Steve Jenkins (stevejenkins.com)
# https://github.com/stevejenkins/pihole-cloudsync
version='5.0'
update='December 26, 2020'
# SETUP
# Follow the instructions in the README to set up your own private Git
# repository BEFORE running this script for the first time. This script
# will not work without a properly configured Git repo and credentials.
# USAGE: pihole-cloudsync <option>
# OPTIONS:
# --initpush Initialize Primary Pi-hole in "Push" mode
# --initpull Initialize Secondary Pi-hole in "Pull" mode
# --push, --upload, --up, -u Push (upload) your Pi-hole lists to a remote Git repo
# --pull, --download, --down, -d Pull (download) your lists from a remote Git repo
# --help, -h, -? Show the current version of pihole-cloudsync
# --version, -v Show version number
# EXAMPLES:
# 'pihole-cloudsync --push' will push (upload) your lists to a remote Git repo
# 'pihole-cloudsync --pull' will pull (download) your lists from a remote Git repo
