What's the scope of a variable in a piece of code that has been require'd?
e.g. say I have a piece of code like this in a file called users.rb:
users = ...
and this line is not in a class or in a method. I then require this file. E.g. in app.rb
require './users.rb'
What's the scope of that variable (users) and how would I access it?
Variables which start with a lower case letter are local variables. Local variables are called local variables because they are local to the scope they are defined in and cannot be accessed from a different scope.

In your particular case, the scope is the script body of users.rb.
how would I access it?
You can't. That's the whole purpose of local variables.
