You can perform unique tasks on Linux or even use your skills to develop something completely new. Hence, learning Linux can bring great opportunities for you. However, as a beginner, you need to make sure you are on the right course.
To help you start your Linux learning journey correctly, we have listed below the top 10 Linux, UNIX, and system programming books for beginners.
These books will undoubtedly help you learn more and develop your skills. They are quite popular reads. Some of the UNIX books listed here were written by authors like Sir Richard Stevens and Sir Brain Kernighan.
01. The Linux Programming Interface: A Linux and UNIX System Programming
This is a relatively newer Linux book, unlike many older UNIX publications. Michael Kerrisk, one of the writers who writes the Linux man pages, is the author of this book. He began using UNIX in 1987 and has been focusing on Linux since the late 1990s, much like many other writers.
While many factors make this book one of the best Linux and UNIX and system programming books for beginners, its primary elements are its thoroughness, comprehensiveness, and writing quality.
02. How Linux Works: What Every Superuser Should Know
If you are thinking of starting your career as a programmer, you need to know how things operate behind the scenes, such as how HashMap functions. You will learn about the inner workings of your Linux computer from this book.
While most programmers spend a lot of time learning programming languages like Java, C++, and others, they spend very little time understanding operating systems like Linux, which is far more beneficial and will likely benefit them for many years. This is the best Linux, UNIZX book that is a must-read for any Linux programmer.
03. The Linux Command Line: A Complete Introduction
Linux is mostly about commands. If you don’t know how to use them, you can’t survive on the system, but if you can, you will be an absolute king.
The Linux Command Line book will help you learn the command line. It enables you to achieve tasks that, in other operating systems, such as Windows or Mac OS X, call for a completely different programmer or tool. This is a book that any new programmer working with Linux needs to acquire. The best part is that the book can be used as a workbook along with a valuable resource for incredible and potent Linux commands.
04. Advanced Programming in the UNIX Environment
Advanced Programming in the UNIX Environment is a timeless classic by Sir Richard W. Stevens; it is one of the best Linux, UNIX, and system programming books. It has been around for more than 30 years and is still going strong. This book will be useful for as long as UNIX is around—which is to say, forever.
Thousands of code examples with concise explanations are included in the book, which is one of its unique factors. Additionally, it has hundreds of images and visuals that demonstrate how various UNIX concepts work. Overall, this book is great for anyone looking to learn and improve their understanding on UNIX.
05. Advanced UNIX Programming—RRochkind
Another book that has recently entered the market, Advanced UNIX Programming by Marc J. Rochkind, is becoming a favorite for students studying UNIX/Linux system programming. This book serves as a workbook and reference at the same time, offering the most thorough coverage of UNIX system calls.
The majority of programmers studied this book or Steven’s before “The Linux Programming Interface” became popular to comprehend the UNIX programming environment. This UNIX instruction is simply outstanding. It includes a brief history of POSIX, SUS, and other UNIX standards in addition to UNIX itself. It also goes over threads, signals, sockets, etc.
06. UNIX and Linux System Administration Handbook, 4th Edition
UNIX and Linux Systems: This book is a little different from the others, but it is still a great resource for learning Linux. It’s a really useful book on UNIX. If you are looking for a good book to learn Linux and UNIX, you can definitely go for this book.
The book is broken up into different administrator sections, such as required administration, which gives a system administrator’s perspective on UNIX and Linux in general.
07. Unix Network Programming (Volume 1)
Sir W. Richard Stevens is a renowned name in the world of UNIX. He is the author of Unix Network Programming, but in addition to this gem of a book, he has written a few others.
This comprehensive book covers many of the network protocols used by Linux and the internet, including POSIX 1003.1–2001 and IPv6. This book is divided into two parts, the first of which is devoted to socket programming.
This is a book you must read if you want to understand real network programming. Although this book’s third edition is the most recent, the previous editions are still valuable to read.
08. UNIX Network Programming, Volume 2: Interprocess Communications
UNIX Network Programming is the second book by Stevens. He has tried to cover socket-based network programming in the first section of the book, and “inter-process communications” is the main topic of this read.
If you are thinking of buying this book, you are making the right decision. Stevens’ books work incredibly well together, making Advanced Programming in the UNIX Environment and these two volumes essential reading for any serious UNIX programmer.
09. The Art of UNIX Programming
Another name in the list of the top 10 best Linux, UNIX, and system programming books, The Art of UNIX Programming, is a great resource for learning UNIX philosophy. There are numerous helpful tidbits within. The book will go into greater detail on “why” than “what” and “how.” Thus, this is the book you should read if you’d like to know why some things in UNIX are done this way rather than that.
10. The Unix Programming Environment
The Unix Programming Environment by Brian W. Kernighan and Rob Pike is the last name on this list of the best books for learning UNIX. This book elucidates the idioms and accurately conveys the Unix philosophy.
Because it was written by two exceptionally skilled technical writers and originated from the original Bell Labs Computing Sciences Research Center, it is also considered an authority on the subject.
This is the list of the 10 best Linux, UNIX, and system programming books for beginners in 2024. Whether you are looking for guidance to pursue a career in this field or you just want to increase your knowledge, these books are super helpful.
