UNIX System Programming with Go

To build fast, reliable, and modern system-level applications, you need to understand how your code interacts directly with the operating system. This text-based course guides you through the foundational concepts of UNIX system programming using Go, one of the most efficient languages for systems work today. You will start with the core architecture of UNIX environments, establish a firm grasp of basic terminology, and quickly progress to writing clean, idiomatic Go code that communicates directly with the kernel. By working through this comprehensive guide, you will transition from writing simple scripts to engineering robust system utilities. You will learn how to manage file systems, handle operating system signals gracefully, process structured data, and structure professional command-line interfaces. What you'll learn: - Understand the core concepts of UNIX system architecture and system calls - Manage file input and output operations efficiently using Go standard libraries - Handle system signals to build resilient and responsive background processes - Parse and manipulate JSON data for configuration and system communication - Build structured, maintainable command-line tools using the Cobra framework - Apply modern Go practices, including proper error handling and context management This course begins with essential theoretical foundations, explaining how the UNIX kernel manages processes and resources. From there, you will explore step-by-step written explanations and practical code implementations that demonstrate how to manage files, intercept signals, and construct polished CLI tools. This course is designed for beginner to intermediate programmers who want to transition from general-purpose Go development to system-level programming. No prior experience with UNIX system internals is required. Gain a deep understanding of system-level operations and start building powerful command-line applications today.
