Hi Mark,

That worked great.  Many thanks. That's the simplest approach I've
seen so far, and I don't see how it could be much simpler

I took a look at shell.rb to see how this command worked.  I'm a Ruby
newbie, so if you have time, please identify what I'm missing in my
understanding (and if you don't, no problem; thanks for what you've
done!):

Shell.new creates a shell object and invokes the initialize method on
that object.  The first thing that method did is initialize the
instance variable @cmd to the result of Dir.pwd, which returns the
current working directory with forward-slash delimiters.

Then the command invokes the pwd method on that initialized Shell
object.  That name is an alias for the cwd instance method. But I
don't see any cwd method defined in the Shell class, nor in its
required modules:
   shell/error
   shell/command-processor
   shell/process-controller
and it didn't seem I'd find it in any of *their* required modules.  (I
only checked the ftool.rb module)

So how do the separators get transformed?  It looks like magic :-)

Richard
