Before we invite our friends to join the conversation, we need to pick a valid, catchy, and available domain name that we can point to the server running our Go code. Instead of sitting in front of our favorite domain name provider for hours on end trying different names, we are going to develop a few command-line tools that will help us find the right one. As we do so, we will see how the Go standard library allows us to interface with the terminal and other executing applications, as well as explore some patterns and practices to build command-line programs.
In this chapter, you will learn:
How to build complete command-line applications with as little as a single code file
How to ensure that the tools we build can be composed with other tools using standard streams
How to interact with a simple third...
