📖 Documentation

This library is compatible with MacOS, Linux, and Windows.

Some operating systems may require root access to flush the DNS cache.

📋 TODO

• Add argument to public static method to get a command for a specific OS. (needs knotsphp/system updated)
• Add support for more operating systems.
• Add support for running elevated commands on MacOS and Linux by passing the password as an argument or having a gui prompt depending of the context. (needs knotsphp/elevated to be written)
