Question

I am doing prep work for App Academy but I am having a hard time setting up files/directories to be able to run everything correctly. I have a couple questions and haven’t been able to find concrete answers:

1. How do you make a directory in the windows terminal?
2. How do you run files previously written in Notepad in IRB? I wrote some simple scripts in Notepad because Sublime was causing me severe migraines. Or how do you change Notepad files to Ruby files?
3. How do you create new files in IRB like test_code.rb?

Answer 1

1) When at the Windows command prompt and having navigated to your working directory, type md directory_name

2) Unless you have specifically told notepad otherwise, notepad will have saved your file as a .txt file. You will simply have to rename the file extension from *.txt to *.rb.

3) When you installed Ruby on your Windows machine, the Ruby interpreter would have undoubtably been added to your path, so you should just be able to run your *.rb file direct from the windows cmd prompt and it will execute.
To load it while in IRB: Make sure you run IRB from the same folder as your *.rb file is in. Once you have cranked up an IRB session, type load 'my_file.rb'.
