We’re going to install Bash, a popular shell and command language that you’d find on Linux and macOS. Windows offers two command line interfaces out of the box: the classic Command Prompt, and PowerShell. The command line, also known as a shell, lets you automate many tasks you do on your computer daily, and is an essential tool for software developers. Instead of clicking buttons with your mouse, you’ll type commands as text and receive text-based feedback. The command line is a non-graphical way to interact with your computer. You’ll use the command line to install and work with Ruby. You will need a computer running Windows 10 with the Creators Update, and access to install software with administrative privileges.

Then you’ll test your environment out by writing a simple Ruby program. You’ll configure Bash on Windows, and then use RVM, the Ruby Version Manager to install the latest version of Ruby and its prerequisites. In this tutorial, you’ll set up a Ruby programming environment on your local Windows 10 machine using the command line. With Bash and WSL installed, you’ll edit your files with your favorite Windows tools, but use Bash and command line tools to execute Ruby and its related tools. Microsoft partnered with Canonical and other Linux distributions to enable native support for the Bash shell and Linux command line tools to solve this issue. Many Ruby libraries are designed to run on Linux, and can exhibit problems when run on Windows. WSL is a Windows 10 feature that lets you run native Linux command line tools on Windows. While there are many ways to set up Ruby on Windows, Microsoft recommends that you use the Windows Subsystem for Linux (WSL) and Bash to do your Ruby development. It’s a great choice for beginners and experienced developers alike.

Ruby is designed to be easy to use and fun for beginners, but powerful enough to create complex systems. It was first released in Japan in 1993, but gained popularity in 2005 as a language for server-side web development. Ruby is a dynamic programming language you can use to write anything from simple scripts to games and web applications.
