- Open your terminal or command prompt and start the Ruby interpreter by typing
irband hitting enter. You should see the Ruby prompt (
irb(main):001:0>) indicating that the interpreter is ready to accept your commands.
- Try out your first Ruby command by typing
puts "Hello, World!"and hitting enter. You should see the output
Hello, World!in the console.

- In your script, add the following code:
puts "Hello, World!"
- Save the file and run it from the terminal or command prompt by typing
ruby hello.rb. You should see the same output as before:
In this tutorial, you’ve learned how to start the Ruby interpreter, run a simple command, and write a full Ruby script. These are the basics of working with Ruby, and you can now start learning more advanced concepts and techniques to build more complex and sophisticated programs.
Note that this is just a brief introduction to Ruby. To become proficient with the language, it’s recommended that you follow more comprehensive tutorials, take online courses, or read books and documentation on Ruby programming.
