Provide the variants only?

Hi!

This repo is great but, what if we want to block only porn sites? or only gambling sites? ❓

All of the files have Unified hosts + Variant

I solved this by overengineering a NodeJS solution 😂 and then realized there’s a very simple way of doing it… 🤦‍♂️

Simple way:

diff --unchanged-group-format='' hosts porn > output_file

My NodeJS script: (downloads the hosts file then porn and then goes through all lines and displays the ones that are in the second file but not first.)

const fs = require("fs");
const wget = require("wget-improved");

try {
	let download = wget.download(
		"https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts",
		"hosts",
		{}
	);
	let download2 = wget.download(
		"https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/porn/hosts",
		"porn",
		{}
	);

	const events = [download, download2];
	const promises = events.map((event) => {
		return new Promise((resolve) => {
			event.on("end", (paths) => {
				resolve(paths);
			});
		});
	});

	Promise.all(promises).then((result) => {
		// console.log("both finished", result);

		// read contents of the file
		const data = fs.readFileSync("hosts", "UTF-8");
		const data2 = fs.readFileSync("porn", "UTF-8");

		// split the contents by new line
		const lines = new Set(data.split(/\r?\n/));
		const lines2 = new Set(data2.split(/\r?\n/));

		let count = 0;

		// usint Sets avoids O(n^2)
		lines2.forEach((line2) => {
			if (!lines.has(line2)) {
				console.log(line2);
				count++;
			}
		});

		console.log("# Size diff: ", lines2.size - lines.size);
		console.log("# Diff count: ", count);
	});
} catch (err) {
	console.error(err);
}

Run it: node diff.js > output_file

P.S. Don’t forget to: npm i wget-improved

I know…old post and all that,but it’s still open so… Linux to the rescue(no need of such a complicated JavaScripts) 😉 : wget https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/porn/hosts -O porn_only.txt sed -i '0,/^# End yoyo/d; /^#/d; s/ #.*//g; /^$/d' porn_only.txt And Voila…you have yourself one healthy porn only list. Enjoy 👍

I just want to throw my support for this in as well. This is a wonderful project, and having the categories only would be good for situations where blocking all the ads isn’t necessarily the goal. I worked in a small library before where this would be handy. This could be used in PiHole or pfBlockerNG as a quick way to help prevent adult content being viewed.
