 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.
