As Ruby pro David Copeland explains, writing a command-line application that is self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, since it combines high-level abstractions with “close to the metal” system interaction wrapped up in a concise, readable syntax. Moreover, Ruby has the support of a rich ecosystem of open-source tools and libraries.

Speak directly to your system. With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. With this book, you’ll learn specific ways to write command-line applications that are easy to use, deploy, and maintain, using a set of clear best practices and the Ruby programming language. This book is designed to make any programmer or system administrator more productive in their job. Now updated for Ruby 2.

As a Rails developer, you care about user experience and performance, but you also want simple and maintainable code. Achieve all that by embracing the full stack of web development, from styling with Bootstrap, building an interactive user interface with AngularJS, to storing data quickly and reliably in PostgreSQL. Take a holistic view of full-stack development to create usable, high-performing applications, and learn to use these technologies effectively in a Ruby on Rails environment.

The “Build Awesome Command-Line Applications in Ruby: Control Your Computer, Simplify Your Life, 1st Edition” is an educational book that demonstrates command-line best practice. David B. Copeland is the author of this programming book. David is a veteran professional software developer who spends most of his time on the command line. He was a principal engineer at Opower and is currently a lead engineer at LivingSocial. With the help of this book, you will learn how to use free, open-source parsers to create a user-friendly command-line interface. This book makes it easy to switch over to other Ruby-based solutions. David does a really excellent job of covering all the details for command-line apps, namely structure, testing, and distribution. Additionally, Build Awesome Command-Line Applications in Ruby is the perfect place to start if you just learned Ruby, or if you want to learn how to build command-line apps as a general skill. This book presents modern cryptography in a way that anyone can understand and makes even the most difficult of subjects easy to learn. In summary, Build Awesome Command-Line Applications in Ruby is a good book for the developers.
