I ran a search for "Unix Dos" in the search field box and checked a few pages' results but did not find what I was looking for. I am trying to find out if there are choices of applications that would enable using Unix commands inside a Windows environment, particularly the DOS Prompt. The only application I've found over the past few months I've been searching for a viable solution has been the UnixDos Toolkit for Windows (http://www.profsoftware.com/unixdos/) but it seems outdated when looking at the current version information under the updates tab (current Version 5.1a Jun 30th, 2004). Are there any other solutions / programs that are supported more frequently, etc.?

Thanks.
