Go Systems Programming

Overview of this book

Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code. Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management. This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.

Summary

In this chapter, we talked about many things, including working with log files, dealing with Unix file permissions, users, and groups, creating regular expressions, and processing text files.

In the next chapter, we will talk about Unix signals, which allow you to communicate with a running program from the outside world, in an asynchronous way. Furthermore, we will tell you how to plot in Go.
