Linux command line. The complete guide

This book provides an extensive overview of Linux command line life. Unlike other books on a single program, such as the bash shell, this book will try to explain how to get along with the command line interface more broadly. How does he work? What can you do with it? What is the best way to use it?
This book is not about Linux system administration. Even though any serious discussion of the command line invariably leads to a discussion of system administration, this book only touches on a narrow range of administrative tasks. But it prepares the reader for additional research, laying the foundations of the knowledge necessary to use the command line as the main tool for solving any serious system administration tasks.
This book is exclusively about Linux. Many books try to expand their target audience to include other platforms such as Unix and macOS. For this reason, they only cover general topics. This book, on the other hand, focuses exclusively on modern Linux distributions. While ninety-five percent of the information will be useful to users of other Unix-like systems, the main target audience for this book is command line users of modern versions of Linux.
