Overview of this book

Linux is the world's most popular open source operating system (OS). Linux System Programming Techniques will enable you to extend the Linux OS with your own system programs and communicate with other programs on the system. The book begins by exploring the Linux filesystem, its basic commands, built-in manual pages, the GNU compiler collection (GCC), and Linux system calls. You'll then discover how to handle errors in your programs and will learn to catch errors and print relevant information about them. The book takes you through multiple recipes on how to read and write files on the system, using both streams and file descriptors. As you advance, you'll delve into forking, creating zombie processes, and daemons, along with recipes on how to handle daemons using systemd. After this, you'll find out how to create shared libraries and start exploring different types of interprocess communication (IPC). In the later chapters, recipes on how to write programs using POSIX threads and how to debug your programs using the GNU debugger (GDB) and Valgrind will also be covered. By the end of this Linux book, you will be able to develop your own system programs for Linux, including daemons, tools, clients, and filters.

To get the most out of this book

To get the most out of this book, you'll need a basic understanding of Linux, some basic commands, be familiar with moving around the filesystem, and installing new programs. It would help if you also have a basic understanding of programming, preferably the C language.

You will need a Linux computer with root access—either via su or sudo—to complete all the recipes. You'll also need to install the GCC compiler, the Make tool, GDB, Valgrind, and some other smaller tools. The particular Linux distribution doesn't matter that much. There are installation instructions in the book for these programs for Debian, Ubuntu, CentOS, Fedora, and Red Hat.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
