Introduction to Go for Command-Line Tools

Command-line tools are the backbone of modern development, automation, and DevOps workflows. Go has become the language of choice for these tools because it compiles to a single, fast binary with zero dependencies. This text-only course guides you through the process of writing clean, efficient, and robust command-line programs using Go's powerful standard library. You will transition from a Go beginner to a confident developer capable of structuring and building executable CLI applications. You will learn how to handle user input, manage files, and structure your code using modern Go conventions. What you'll learn: - Understand core Go syntax, basic types, and foundational programming concepts - Manage project dependencies and structure your code using modern Go modules - Parse command-line flags and arguments using the built-in flag package - Read and write files, handle system signals, and manage external processes - Implement robust error handling and write unit tests using the testing package - Compile your code into lightweight, cross-platform native executables The course starts with essential Go terminology and installation steps, then guides you step-by-step through syntax, control structures, and standard library packages, culminating in the creation of practical CLI utilities. This course is designed for beginners, system administrators, and developers new to Go, requiring no prior experience with the language.
