Beschreibung

Focusing on the Executable and Linkable Format (ELF) used in Linux and Unix systems, this book explores how code is compiled, linked, and loaded into memory, and how the operating system executes it. You’ll learn to analyse ELF files, debug and optimize programs at the binary level, write custom linker scripts, and understand dynamic linking and symbol resolution.

ELF files are important because low-level programming and binary analysis are critical skills for system programmers, embedded developers, and security researchers. With the rise of performance optimization, cybersecurity, and resource-constrained environments (e.g., IoT), understanding executables is more relevant than ever.

Executable Files for Linux provides a hands-on, modern approach to a topic often overlooked in learning resources today.

What You Will Learn

· · · · · Explore kernel-level processes for loading and executing binaries

Who This Book Is For

Developers and programmers working on operating systems, embedded systems, or low-level software as well as performance engineers and security professionals
