Could you post some code and/or output? Your jargon is impenetrable.

You should be able to call #read on your IO object to slurp the entire  
contents. IO is standard library, so you can find docs in all the usual  
places. I’d start here:

[http://ruby-doc.org/core/classes/IO.html](http://ruby-doc.org/core/classes/IO.html)

Good luck!
