Thanks! Two questions:

1.

How would I write

commands = Commands.new ['this -x -y','that -a -b']
commands.each do |cmd|
   returned = cmd.issue # or ".run", ".enter", ...
   case returned
     when Stderr then raise returned
     when Stdout then puts  returned
   end
end

then?

2. Will it run unchanged on Win and Lin, etc?

TIA,

Tobi
