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.

Which files are considered system files?

Each Unix operation system contains files that are responsible for the configuration of the system as well as its various services. Most of these files are located in the /etc directory. I also like to consider log files as system files, although some people might disagree. Usually, most system log files can be found inside /var/log. However, the log files of the Apache and the nginx web server can be found elsewhere, depending on their configuration.
