Need help with PROJ

Hi!

I have binary file containing a DEM which has a lat/lon projection.
I have tried to convert it to polar stereographic with PROJ1.3:
'proj +proj=ups +north euro.img -b > new.img'

The new file is just full of garbage. Does anybody know how to
change projection on binary files?

Thanks in advance from,
