"I have discovered that there are two types of command interfaces in the world of computing: good interfaces and user interfaces"

This quote by Daniel J. Bernstein is describing the 2 kinds of command user interfaces utilized in computing. A good user interface is one that is simple to use and understand, and provides the user with a smooth and efficient experience. A user interface, on the other hand, is one that is more complicated and hard to utilize, and typically requires more effort from the user to understand and utilize. Great user interfaces are developed to make the user's experience as simple and simple as possible, while interface are designed to offer more control and modification choices. By comprehending the distinctions between these 2 kinds of command interfaces, developers can produce better user experiences and more effective computing systems.
