Okay, after a fair amount of searching, including some blind guessing, I came across some old ruby-talk posts mentioning Open3, which seems to do what I want: Open3.popen3('jive') { |wtr,rdr,err| wtr.puts "what is up?" wtr.close puts rdr.gets } This points up my major frustration with Ruby-- I had to completely guess as to how Open3 worked, or *even that it existed at all*. There are no docs I can find for it, and this makes developing with Ruby more of a pain than it needs to be. If I were doing this in perl, I'd just have to 'perldoc -q pipe', and instantly I have docs on IPC::Open2 and a reference to IPC::Open3 if I need that. Pardon the gripiness, please, but I really hate guessing about my programming language. POLS is nice, but having easily accessible docs to confirm all the corner cases is even better, IMO. -=Eric -- Come to think of it, there are already a million monkeys on a million typewriters, and Usenet is NOTHING like Shakespeare. -- Blair Houghton.
