 The core script of Pi-hole provides the ability to tie many DNS related functions into a simple and user friendly management system, so that one may easily block unwanted content such as advertisements. For both the Command Line Interface (CLI) and Web Interface, we achieve this through the `pihole` command (this helps minimise code duplication, and allows users to read exactly what's happening using `bash` scripting). This "wrapper" elevates the current user (whether it be your own user account, or `www-data`) using `sudo`, but restricts the elevation to solely what can be called through the wrapper.
