Have a google for 'command-line ruby' and read up on the gets() method. As far as where to put client.rb, that could be anywhere given the command-line you quoted. Starting the ruby method's first argument with a dot-slash means "starting in the current directory…" and the rest just points the ruby executable to the file client.rb in that directory. Are you meaning to call a Rails application using this command-line interface? Have a read on the Rails Runner. I don't remember anything about it except I saw it mentioned in passing in AWDWROR when I read it years ago, never used it.
