In 2006, Microsoft released
Windows Powershell, a new command line shell that, via cmdlets, scripts, and executables, allow core system administration tasks to be scripted. While this functionality has been available on Unix-type systems for decades, Microsoft's version will almost certainly, within a few years, be available on several hundred million PCs. So
how does the Powershell stack up against Linux favorite bash? MSDN links to this
