Summary

We have learned in this chapter how to log in to a system with a user and with root, understanding the basics of permissions and security. We are now also more comfortable using the command line with autocomplete, navigating through the directories and files, packing, and unpacking them, redirecting command output and parsing it, and even automating processes with shell scripts. More importantly, we have a way to obtain information on what we are doing (or want to do) available in any RHEL system with the included documentation. These skills are the basis of the upcoming chapters. Don't hesitate to revisit this chapter if you feel stuck or if your progress is not as fast as you thought.

Now, it is time to extend your knowledge to encompass more advanced topics in the upcoming chapters. In the following chapter, you will be getting used to the tools for regular operations, in which you will review the most common actions taken when managing a system. Enjoy!
