suppressing IRB output?
irb, ruby, ruby-on-rails
Solution
Just add `nil` to the end of your command. It doesn't kill irb's response line, but if you have some large object, it avoids blasting your screen.

Problem
Possible Duplicate: Rails console, how to stop output of return value? Consider this session in IRB: ``` >> for a in 1..5 do ?> puts a >> end 1 2 3 4 5 => 1..5 >> ``` How do I suppress the output `=> 1..5`? This is important if I do this in a Rails console session: ``` for post in Post.find(:all) do if post.submit_time > Time.now puts "Corrupted post #{post.id} is from the future" end end ``` I don't want all the Posts to be printed as an array at the end. How do I suppress that output? I am sure there are other ways of doing this, like `find_each` or a Ruby script but I am more interested in doing this in an interactive session.
