Get Programming with Go

Go is a popular choice for writing DevOps and systems programs, and command-line tools in particular. How can we write simple, powerful, idiomatic, and even beautiful tools in Go? This book covers all the necessary techniques: functional options, flags and arguments, files and filesystems, executing commands, writing shells and pipelines, JSON and YAML wrangling, and even sophisticated API clients. Even more importantly, the book teaches you how to think like a master software engineer: how to break down problems into manageable chunks, how to test functions before they're written, and how to design Go CLIs that delight users.
