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

What is this for?

hBlock is a POSIX-compliant shell script that gets a list of domains that serve ads, tracking scripts and malware from multiple sources and creates a hosts file, among other formats, that prevents your system from connecting to them.

Installation

hBlock is available in various package managers. Please check the PACKAGES.md file for an up-to-date list.

The latest available version can also be installed manually by running the following commands:

curl -o /tmp/hblock 'https://raw.githubusercontent.com/hectorm/hblock/v3.1.2/hblock' \
  && echo '0f5a0f6219a346be5551760e6ec5245c56cae146c5fb05fdc752819e0e93b42f  /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 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 hblock.1.md file for the full list.

Nightly builds

Nightly builds of the hosts file, among other formats, can be found on the hBlock website.
