How to execute a Ruby script in Terminal?

Question

I've set everything up that I need on my Mac (Ruby, Rails, Homebrew, Git, etc), and I've even written a small program. Now, how do I execute it in Terminal? I wrote the program in Redcar and saved it as a .rb, but I don't know how to execute it through Terminal. I want to run the program and see if it actually works. How do I do this?

Answer 1

In your terminal, make sure you are in the correct folder by typing

ls

You should see your .rb file. Then, in the terminal, you can type

ruby my_file.rb
