How Linux works: the ultimate guide
Ever wanted to learn how the internals of your Linux desktop work? In this article we're going to explain how everything in a modern Linux distro works, start to finish.
How it works: Userspace
Before we delve into the Linux underworld, there's one idea that's important to understand. It's a concept that links userspace, privileges and groups, and it governs how the whole Linux system works and how you, as a user, interact with it. It's based on the premise that a normal desktop user shouldn't be able to make important system changes without proving that they have the correct administrator's privileges to do so. This is why you're asked for a password when you install new packages or open your distribution's configuration panels, and it's why a normal user can't see the contents of the /root directory or make changes to specific files.
Your distribution will use either sudo or an administrator account to grant access to the system-wide configurable parts of your system.
