Unix System Programming and Performance Essentials

To build fast and reliable software, you need to understand how your code interacts directly with the operating system. Writing truly efficient applications requires a solid grasp of Unix system architecture, resource management, and execution mechanics. This written course guides you from Unix basics to performance optimization. You will learn how the kernel manages resources and how to write programs that leverage system calls, file systems, and processes effectively. What you'll learn: - Understand foundational Unix architecture, system calls, and core kernel concepts - Manage processes, threads, and inter-process communication (IPC) mechanisms - Implement efficient file I/O operations and memory management techniques - Analyze and optimize system performance using standard diagnostic tools - Explore modern Unix concepts including namespaces, cgroups, and containerization fundamentals - Write robust shell scripts to automate system tasks and manage workflows You will start with essential terminology and command-line basics before progressing to low-level programming interfaces. Through detailed written explanations and code examples, you will explore how to measure, analyze, and improve application execution speed. This course is designed for aspiring system programmers, software developers, and system administrators who want to understand the inner workings of Unix-like operating systems. No prior system programming experience is required. Start reading today to unlock the full potential of Unix system performance.
