I have a Windows and I'm using Ruby 1.9.1-p429, and it won't allow me to view my test.rb file on cmd when i type cd. I'll go through step-by-step of what I did.
I saved a test .rb file on Sublime to my desktop. I open cmd and type "cd", expecting it to list the test.rb file, as the About.com tutorial said it would. Nothing shows up.
I go to the files on my desktop and open it. It says I need a program to open it with. I try opening it with Ruby Interactive. Nothing. The same thing happens when i try to open it with cmd. Now all the save files try to open it with cmd.
