In this chapter, we started off with a walkthrough of creating new users. We explored how to do so using Mint's handy Users and Groups tool as well as via the shell. Then, we explored removing a user permanently as well as blocking access on a temporary basis. Next, we went over groups in Linux and how to add and remove them. Our journey then explored how to run commands as other users, and then we had a more in-depth look at the sudo command and how to configure it. This chapter then ended with a detailed look at how permissions in Linux are handled.

In the next chapter, we will explore networking in Mint, including connecting to wired and wireless networks, setting up a static IP, accessing your system via SSH, as well as sharing files.
