Depending on your needs, the Windows port of Busybox might do the trick. Personally, I don't like the shell that much. As others pointed out, it is a consistency-lacking set of programs that often do only trivial tasks (by design). A proper cross-platform scripting language such as Perl, Python or Newlisp. The latter is very much like Busybox : it packs a lot in a small single executable (plus it is a Lisp-like language so the syntax is simple and the documentation is good).
