Cygwin like Module in perl

[perl pra]

Hi Gurus,


I want  to execute  some of the unix commands on windows, Presently we are
using Cygwin to run unix commands on Windows.

Now I need to convert all the shell scripts into perl scritp. Is there any
module in perl which allows me to execute unix commands on Windows.

My windows version Windows 2003 EE.

Thanks in Advance.
