Is it possible to create a CSV file right out of the command line in IRB or elsewhere with a one-time use on it. Say, I just need a CSV file with all my user's first name on it.
Can I create that without setting up any architecture?

Yes, use Ruby's csv
library (it's part of the standard lib):

What database are you using? It seems doubtful that you'd need to use Rails at all. For example:
