Gimp script-fu question

[bjy20716]

I am trying to use a script I found online with the windows version of Gimp.

Script

I placed the script in my scripts directory, but how do I run it in windows, not unix?

It says to run it:
The command line invocation is:
gimp --no-data --no-fonts --no-interface -b '(batch-scale "filename.xtn" x-factor y-factor)' '(gimp-quit 0)'

Can I make a dos bat file with
"gimp --no-data --no-fonts --no-interface -b '(batch-scale "*.png" 640 0)' '(gimp-quit 0)'
To run the script in windows? Or it has to be ran in unix?

thanks
