Improve your security and privacy by blocking ads, tracking and malware domains.

## What is this for? This POSIX-compliant shell script, designed for Unix-like systems, gets a list of domains that serve ads, tracking scripts and malware from [multiple sources](./SOURCES.md) and creates a [hosts file](https://en.wikipedia.org/wiki/Hosts_(file)) (alternative formats are also supported) that prevents your system from connecting to them. ## Installation hBlock is available in various package managers. Please check the [PACKAGES.md](./PACKAGES.md) file for an up-to-date list. The latest available version can also be installed manually by running the following command: ```sh curl -o /tmp/hblock 'https://raw.githubusercontent.com/hectorm/hblock/v2.1.7/hblock' \ && echo 'e357fc9439d7b79036c7939f976aab9cbd25878c4651e5a757e30ff96452edc2 /tmp/hblock' | shasum -c \ && sudo mv /tmp/hblock /usr/local/bin/hblock \ && sudo chown root:root /usr/local/bin/hblock \ && sudo chmod 755 /usr/local/bin/hblock ``` Additionally, a [systemd timer](resources/systemd/) can be set to regularly update the hosts file for new additions. ## Usage The default behavior of hBlock can be adjusted with multiple options. Use the `--help` option or check the [USAGE.md](./USAGE.md) file for the full list.
