You know when you do rails generate controller abc def
you get a file def.html.erb
that's an ERB file, an Embedded Ruby file
The contents of that file get preprocessed , such that anything outside of <%..%> gets outputted, and anything inside <%...%> gets executed and <%=....%> involves execution and a result outputted.
PHP has a similar concept.. PHP though also has a PHP.EXE file that you can run a file through and get the output.
I see it now, it's mentioned here

I suspect you're looking for "irb" -- Interactive Ruby.No, ERB is not IRB. ERB is called Embedded Ruby, people often use it when they use Rails.
