You can open a .rb file in command prompt.

Here are the steps:

1. Open the command prompt (search for 'command prompt' or 'cmd.exe.') you should see this:

   C:\Users\username>

2. For example I am keeping this file in Desktop and in a folder named Ruby, type in the path to the folder like this:

   cd Desktop\Ruby

   You should see this:

   C:\Users\username\Desktop\Ruby>

3. Enter the name of the folder, then the file name:

   Ruby *example.rb*

4. If else fails, check your code for errors. The command prompt will give you a hint for example:

   example.rb:5: syntax error, unexpected keyword_end, expecting end-of-input

   This means that your error has something to do with the code, end, and is on line 5.

Good luck opening a .rb file!
