Chapter 1: Overview of the Book

The book titled "How Linux Works" by Brian Ward spans 435 pages and was published by No Starch Press in 2021. It delves into the architecture and functionality of Linux, covering essential topics such as:

• Structure and functionality of Linux
• Basic command usage and navigation
• Shells: Their definition and how to modify the default shell
• File modes and permissions
• Understanding device files and SCSI
• Partitioning and file systems
• Bootloaders and system management
• User management and process allocation
• Network configuration and applications
• Basics of shell scripting
• File transfer and sharing over networks
• User environments and Linux desktop surveys
• Development tools: C, Python, Perl, Java, and more
• Introductory guide to compiling in C
• Virtualization, including virtual machines and containers

No Starch Press consistently delivers exceptional technology books, and having previously read "How Linux Works" 2nd edition, I found the 3rd edition to be a worthy continuation. While the newer edition includes a chapter on virtualization and some historical insights, it doesn't present a significant overhaul from its predecessor. Without the 2nd edition for direct comparison, I suggest that those who already possess the earlier version might consider waiting for a potential 4th edition before making a purchase.

As I prepare for the CompTIA Linux+ certification, I appreciate the comprehensive coverage and clarity that this book provides. The hallmark of No Starch Press publications is their ability to simplify complex topics, making them accessible.

If you have prior exposure to Linux, you might find that you can skip certain sections of this book. Conversely, for those new to the subject, this text serves as an excellent primer, offering a solid foundation in various Linux topics.

For beginners, "How Linux Works" is an ideal starting point or a valuable addition to your reading list. It provides a straightforward way to refresh your existing knowledge. However, if this is your first encounter with Linux, you might need to consult tutorial videos on installation and setup, as the book assumes you already have a Linux environment in place.

Overall, "How Linux Works" is a fantastic resource for both novice and intermediate Linux users, allowing for a review of topics that may not have been fully grasped before. I would rate this book ★★★★ out of 5.

The first video, "How the Sausage Is Made," provides a unique perspective on the creation process of various technologies, including Linux, which may enhance your understanding of the subject matter.

The second video, "Do You Know How Sausages Are Made?" offers insights into the behind-the-scenes processes, making it a fitting complement to the themes discussed in the book.
