Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

In this chapter, you have learned how to work with the most commonly used commands in Linux. You now know how to manage (create, delete, copy, and move) files, how the filesystem is organized, how to work with directories, and how to view file contents. You now understand the shell and basic permissions. The skills you have learned will help you manage files in any Linux distribution and edit text files. You have learned how to work with vim, one of the most widely used command-line text editors in Linux. Those skills will help you to learn how to use other text editors such as nano and emacs. You will use these skills in almost every chapter of this book, as well as in your everyday job as a systems administrator.

In the next chapter, you will learn how to manage packages, including how to install, remove, and query packages in both Debian- and Red Hat-based distributions. This skill is important for any administrator and must be part of any basic training.
