Fun fact, though: Linux is the only case-sensitive one.

Least favorite part of linux honestly

Case-insensitive filesystems are for maniacs. They are only causing trouble. Ever had two folders with the same name but different capitalization in windows? You see both, but whichever you click it will always open the same one, while the other can’t be accessed. Psychopath behavior.

In my decades of IT work I have literally never seen this to be an issue. To myself or others.

Your username is 3 words. At a quick glance maybe they are 3 directories. I guess I have to use another command to find out.
