Managing File Systems in Go for CLI Tools

When building command-line utilities, system tools, or backend services, interacting with the host file system is an absolute necessity. Understanding how to handle paths, read and write files, and manage directories safely across different operating systems is a core skill for any developer. This course provides a clear, text-based path to mastering file system operations in Go, ensuring your applications are robust, fast, and cross-platform compatible. You will transition from a basic understanding of Go syntax to confidently writing programs that manipulate files, manage permissions, and archive data. Through clear written explanations and practical code examples, you will learn how to handle real-world challenges like concurrent file access and modern path manipulation. What you'll learn: - Understand core file system concepts, permissions, and basic Go input/output primitives - Navigate and manipulate paths safely across Windows, macOS, and Linux using modern path packages - Create, read, update, and delete files and directories with proper resource cleanup and error handling - Archive and compress data using standard archive formats built directly into Go - Implement structured logging to track file operations and system events - Apply concurrency safely when reading or writing to multiple files simultaneously This course starts with fundamental concepts, explaining how operating systems view files and how Go maps to these structures. You will then progress through practical file operations, directory traversal, and advanced patterns like archiving and concurrent safe writes. This course is designed for beginner to intermediate Go developers who want to build practical system tools and command-line applications. No prior experience with file system APIs is required.
