Around the second semester, our lecturer introduced us to a different perspective, focusing on computer security. The lecturer was highly skilled with Linux, and everything was done using this operating system. To demonstrate their expertise, they showed us how to create new users in Linux via the terminal. To make it easier for us to understand, we were given an assignment to create a user-friendly interface with menu options displayed on CMD, terminal, or similar environments. Below is the result.
