The above script installs the fonts from Hack typeface repository by requested release version number on the Linux platform. This script can be used for initial installs and upgrades to new versions (or downgrades if ever necessary).

Usage

$ ./hack-linux-installer.sh [VERSION]

Define the version number in the format vX.XXX. You must use a lowercase v followed by the version number sequence that is used in the repository releases. For instance, to install Hack v3.003, use the following:

$ ./hack-linux-installer.sh v3.003

What it does

• The release archive is pulled from the repository release
• The release archive is unpacked
• The fonts are installed on the path $HOME/.local/share/fonts
• The font cache is cleared and regenerated
• fc-list | grep "Hack" is executed to display the installed font paths. You should see valid output from this command.
