There are more than one Bash ports for Windows. I was using win-bash in the past. It is also on
SourceForge. You can install it onto Microsoft Windows NT based systems. I have not tested whether it covers everything what you need, but it is the most complete Bash port for Windows that I have used so far and since it has GNU General Public License version 2.0 (GPLv2), it should not be too complicated to issue new tickets with your requests.
Interesting, I will have to check it out! My script doesn't utilize any special commands and is really only reliant on "grep" and reading simple passed arguments so I believe it would work.
Thanks for the information!
