porting unix commands is handy, but it's not native to windows.
I would like to see some native windows commandline utilities like, let's say they make one called msconv (for MS convert) and you can say like:
msconv thisSheet.xls -F -S=1 --to_CSV
and it spits out sheet 1 to thisFile.csv
msconv thisDoc.doc -F --to_HTML
(F to assume yes and Force any conversion complaints)
And by all means guys, if you want to develop this, feel free to freely use any ideas I'm posting. If you guys had a good native command line it would make Windows a much much better product.
Keep us posted on MSH!
