a slightly less trickey way to do it (and apologies if this was already
proposed, I've been kinda skimming this thread up til now) would be to call
your ruby program from a cmd file, and call another cmd file right after.
then your ruby program could re-write the second cmd file.

like this:

doit.cmd contents:
    ruby myprog.rb
    followup.cmd

followup.cmd contents (written by myprog.rb):
    cd c:\whatever\

..pretty sure this would work, if you can't get the originally proposed
command line magic to work. It'd work as .bat files too, so you could use
it in Win98 or DOS or whatever.

Why was that so obvious _after_ I read it? Thanks much. Works like a charm.

The best answer to most questions is "it depends".

Sure it was, it's how I got Rake to drop me off in the newly created
directory when I give it a 'new_app' task :slight_smile:
