Linux is a family of open-source Unix-like operating systems based on the Linux kernel. Linux is the brainchild of Linus Torvalds. He made Linux for fun apparently and released the first version of Linux on 17 September 1991.
Sources I used to learn the Terminal and Bash script:
NetworkChuck ‘s tutorial (Hard to believe it’s free).
@amirtha255 ‘s article, that made me stop overthinking.
Bash scrip by freeCodeCamp.
Google 😅.
