Optimise Pihole's gravity.list

If you are making use of Pihole's regex filtering and/or DNSMASQ wildcards, then it's likely that your gravity.list contains far more domains than necessary.

Example

Regex:

^(.+[-_.])??ad[sxv]?[0-9]*[-_.] matches 19,268 unnecessary entries in my gravity.list file.

DNSMASQ Wildcard:

address=/302br.net/0.0.0.0 matches 16,327 unnecessary entries in my gravity.list file.

What does the script do?

1. Identifies gravity.list entries that do not match items in your regex.list
2. Identifies gravity.list entries that do not match items in any DNSMASQ conf files.
3. Creates a new, optimised gravity.list

Instructions

• All commands will need to be entered via Terminal (PuTTY or your SSH client of choice) after logging in.
• Each time pihole -g is ran, either through updates, automatic cron or manually, any entries that were previously removed by this script will be re-added.
