Book Description
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. Writing a command-line application that's self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, because it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Plus, Ruby has the support of a rich ecosystem of open source tools and libraries. Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason why a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users. With Ruby, the command line is not dead. Long live the command line.

Book Description
Rails is a framework written in Ruby that helps you build web applications. There are a lot of concepts packed into that one sentence that may be new to you, but don't worry, we'll get you feeling cozy.Ruby is a programming language. While there are many others (e.g. Python and Java) and they can mostly accomplish the same tasks, Ruby is a particularly readable and fun one, so you've made a good choice. If we were building a house, Ruby would be the raw materials: plywood, nails, etc. Rails is a framework written in (and for) Ruby - think of this as the frame for the house. It gives you certain parameters to work within, but you have a lot of flexibility about how the final product turns out. Just like the frame is built from the same raw materials that will be used to fill in the details of the house, Rails is written in Ruby, and you will add all of your application-specific features using Ruby (and HTML, and CSS, etc.).Through your instructions in Ruby, Rails will take information stored in a database and send HTML to be displayed to the user in a browser. Let's get going!
