This book will provide good, in-depth explanations of various interesting Go concepts. It begins with Unix and system programming, which will help you understand what components the Unix operating system has to offer, from the kernel API to the filesystem, and allow you to familiarize yourself with the basic concepts of system programming.
Next, it moves on to cover the application of I/O operations, focusing on the filesystem, files, and streams in the Unix operating system. It covers many topics, including reading from and writing to files, among other I/O operations.
This book also shows how various processes communicate with one another. It explains how to use Unix pipe-based communication in Go, how to handle signals inside an application, and how to use a network to communicate effectively. Also, it shows how to encode data to improve communication speed.
The book will, toward the end, help you to understand the most modern feature of Go—concurrency. It will introduce you to the tools the language has, along with sync and channels, and how and when to use each one.
