You can set up irb to limit the number of chars it prints. Put the 
following code in your .irbrc. This was originally written by Stian Haklev.

class IRB::Context
   attr_accessor :max_output_size

   alias initialize_before_max_output_size initialize
   def initialize(*args)
     initialize_before_max_output_size(*args)
     @max_output_size = (IRB.conf[:MAX_OUTPUT_SIZE] ? 
IRB.conf[:MAX_OUTPUT_SIZE] : 500)
   end
end

class IRB::Irb
   def output_value
     text =
       if @context.inspect?
         sprintf @context.return_format, @context.last_value.inspect
       else
         sprintf @context.return_format, @context.last_value
       end
     max = @context.max_output_size
     if text.size < max
       puts text
     else
       puts text[0..@context.max_output_size-1] + "..." + text[-2..-1]
     end
   end
end
