While there are many more advanced filesystem features that are very interesting, we want to focus on what makes the Linux filesystem distinctively Linux: the filesystem structure. If you're used to Windows, this will probably be the single most confusing difference between the two operating systems. If you're coming from macOS, the difference is still noticeable, but much smaller: this is a result of macOS being a Unix operating system, which has obvious similarities with the Unix-like Linux structure.
We're going to be interactively exploring the Linux filesystem from this point on. We advise you to follow along with the code examples that follow, since this increases information retention significantly. Besides that, your system might look differently from the one we use, should you have chosen not to use Ubuntu 18.04 LTS for...
