getBlockLists.sh

#!/usr/bin/env sh

# Download lists, unpack and filter, write to gzipped file 
curl -s https://www.iblocklist.com/lists.php \
| grep -A 2 Bluetack \
| sed -n "s/.*value='\(http:.*\)'.*/\1/p" \
| xargs wget -O - \
| gunzip \
| egrep -v '^#' \
| gzip - > bt_blocklist.gz

Works on ubuntu 16x

works for me in Debian 10. I added "-1" option to the 'gzip' command at the end of the script to speed up compression.

| gzip -1 - > bt_blocklist.gz
