put this into your ~/.irbrc if you like do some text stuff in your ruby console which you want to paste somewhere else. Use "pbcopy a" to copy the contents of a to the pasteboard.

pbcopy.rb

require 'tempfile'

def pbcopy(s)
  tmp_file = Tempfile.new("pbcopy")
  begin 
    tmp_file.write(s.to_s)
    tmp_file.rewind
    system "/bin/cat #{tmp_file.path} | /usr/bin/pbcopy"
  ensure
    tmp_file.close
    tmp_file.unlink
  end
end
