Unix System Programming and File I/O in Go

To build reliable system utilities and DevOps tools, you must understand how to interact directly with the underlying Unix system. This text-based course guides you through the core concepts of system programming, showing you how to write efficient Go code that manages system resources and processes data. You will start with the fundamental principles of Unix architecture before moving on to practical file operations and configuration parsing. By completing this course, you will be able to confidently write Go programs that read files, handle system inputs, and manage structured configuration files. You will transition from writing basic scripts to developing robust system utilities that follow Unix design principles. What you'll learn: - Understand Unix system principles and how Go interacts with the operating system kernel - Read and process large text files efficiently using Go standard library scanners - Parse and manage structured configuration data using modern YAML packages - Handle system inputs, outputs, and standard error streams correctly in your utilities - Apply robust error handling and file closure patterns to prevent resource leaks - Structure your Go CLI applications for maintainability and clean execution This course begins with essential Unix concepts and Go system packages, establishing a solid foundation. You will then progress through written explanations and code walkthroughs that demonstrate real-world file I/O operations and configuration parsing. This course is designed for beginner to intermediate Go developers who want to expand their skills into system-level programming and tool development. No prior experience with Unix system calls is required. Start reading today to build your own efficient Unix system utilities with Go.
