No - at least, not generally, for the more or less obvious reason that *nix
tools are not generally present on Windows.
But if you have a system call with _exactly_ the same name and options it
should work (windows isn't case-sensitive for system calls/tools; unix is)
Under windows, too, constructing batch files with suitable names (eg 'ls.bat')
can go some way to making unix-like things at least run windows equivalents.
But you'd have to do a lot of work to get identical output.

R already does that automatically.
