Why don't you just install the shell itself (bash, ksh, etc)?
cygwin will install a set of tools on your PC that include several shells.
If, for some reason, you don't want to install cygwin either, you can find KSH for Windows and probably bash as well. Otherwise, you'll have to crack open the books and pretend.
And by the way, posting the same message in more than one forum is against the
rules.
