1. History
Hey rookie! So you decided to dive into this wonderful world known as Linux? It’s gonna be a beautiful and enjoyable road ahead! My name is Penguin Pete and I’m here to guide you through this journey. Let’s get started with a little bit of backstory about Linux.
To learn about how Linux came to be, let’s go back to the beginning to 1969 where Ken Thompson and Dennis Ritchie of Bell Laboratories developed the UNIX operating system. It was later rewritten in C to make it more portable and eventually became a widely used operating system.
A decade or so later, Richard Stallman started working on the GNU (GNU is Not UNIX) project, the GNU kernel called Hurd, which unfortunately never came to completion. The GNU General Public License (GPL), a free software license, was also created as a result of this.
The kernel is the most important piece in the operating system. It allows the hardware to talk to the software. It also does a whole lot of other things, but we’ll dig into that in a different course. For now, just know that the kernel controls pretty much everything that happens on your system.
During this time other efforts such as BSD, MINIX, etc were developed to be UNIX like-systems. However, one thing that all these UNIX like-systems had in common was the lack of a unified kernel.
Then in 1991, a young fellow named Linus Torvalds started developing what we now know today as the Linux kernel.
In the previous lesson, we learned about the Linux kernel which powers millions of devices a day. One thing before we move forward, the term Linux is actually quite a misnomer, since it actually refers to the Linux kernel. However, many distributions use the Linux kernel so therefore are commonly known as Linux operating systems.
A Linux system is divided into three main parts:
Hardware - This includes all the hardware that your system runs on as well as memory, CPU, disks, etc.
Linux Kernel - As we discussed above, the kernel is the core of the operating system. It manages the hardware and tells it how to interact with the system.
User Space - This is where users like yourself will be directly interacting with the system.
So the first step we’ll need to take is to install Linux on your machine. You have many options to choose from and this course will help inform you and get you started on choosing a Linux distribution.
There are many Linux distributions to choose from, we’ll just go over the most popular options.
