Go Systems Programming: Building UNIX CLI Tools with Cobra

Systems programming is the backbone of reliable software infrastructure, but transitioning from general application development to low-level system interaction can feel daunting. Go simplifies this transition by combining high-performance system access with a clean, readable syntax. This text-based course guides you from a beginner to a confident systems developer. You will learn how to interact directly with UNIX environments, manipulate files, handle system signals, and build production-ready command-line utilities that users love. What you'll learn: - Understand foundational UNIX system concepts, environment variables, and process lifecycles. - Read and write files efficiently using Go's standard library, including structured JSON and XML handling. - Manage system signals and implement clean application shutdown using modern context patterns. - Build structured, interactive command-line interfaces (CLIs) using the Cobra and Viper packages. - Apply modern Go practices, including structured logging with the standard library's slog package. - Practice writing robust, testable system code through step-by-step written exercises and code analyses. The journey begins with key terminology and foundational UNIX concepts before moving into hands-on file input/output operations. You will then progress to advanced process management and finish by designing fully functional command-line applications. This course is designed for developers who know basic Go syntax and want to dive into systems programming and CLI tool development. No prior systems programming or UNIX administration experience is required. Start reading today to unlock the power of low-level systems development with Go.
