Command-Line Development

Back before Windows and GUI shells, there was the command line. But in this modern age, command-line development is still an important tool to have in your toolbox. Command-line programming is important for scriptable utilities, one-off applications, complex data processing applications, and yes, cloud-based software development. In this presentation, we will review the fundamental concepts of command-line development; how to use stdin, stdout, and stderr for I/O; and inter-process communication between command-line processes. We will look at command-line development across multiple languages including .NET, Java, Python, Ruby, and Node.js.
