# Introduction Welcome to the Supernatural Academy for the technologically gifted, where the elite hackers and code whisperers of tomorrow sharpen their skills. Within these mythical walls lies a challenge that will test the practical abilities of our most promising student: you! Your mission, should you choose to accept it, is to navigate the cryptic corridors of Linux user environments and harness the power of user switching. As your initiation, you will master the subtle art of `su` (substitute user) and prove your worth to the grandmasters of code. This will not only enhance your terminal wizardry but also prepare you for the dire circumstances where you must seamlessly morph from one user identity to another. Are you ready to accept this challenge and join the pantheon of Linux luminaries?
