Alternatively num = line[/^Success - new device-id: \((\d+)\)/, 1] and puts num I find the solution with String#[] very elegant. :-) Btw, if there is always just one number this shorter solution will work as well - but is not so robust against other inputs: num = line[/\d+/] Kind regards robert -- remember.guy do |as, often| as.you_can - without end http://blog.rubybestpractices.com/ -- You received this message because you are subscribed to the Google Groups ruby-talk-google group.
