In this chapter, we looked at the principles behind user and group accounts under SUSE Linux. We've examined how user and group accounts can be created, edited, and deleted using the GUI, as well as the command-line prompt. We also looked at how passwords can be manipulated both by the root user and by the individual users themselves.
Finally, you learned how the sudo command can be used to run root-only programs, allowing users to avoid needing to switch to root user frequently.
In the next chapter, we'll look at how the system can be optimized. You'll also learn about several interesting and important system tools.
