Build Awesome Command-Line Applications in Ruby
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. 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. ...

Pro Windows PowerShell
Windows power users have always envied their friends running UNIX machines for the ease of automation that they enjoy. The traditional Windows command-line shell, cmd.exe, has never been up to par with shells like bash or tcsh, especially when it comes to text processing and process automation. Windows PowerShell changes all that. This next-generation shell is also a full-blown scripting environment with a real programming language that allows users to access every part of their operating system. Files, registry entries, and COM and .NET objects are all supported by PowerShell, which makes manipulating them a breeze. ...
