Thanks for getting back to me.

Most of the errors are Error 1, can not create a dataset or can not open
a dataset. It is not running from within the shell I don't think so I
had to set the GDAL_DATA environment variable. Can I pass the command to
the FWTools shell with a batch file because at the moment I'm using

What error do you get?

Are you running the command from within the FWTools shell?  There are
several environment variables needed for correct operation of ogr2ogr,
and they are normally defined in the FWTools shell environment, but not
outside it.  In particular, EPSG:4277 won't be correctly expanded unless
the GDAL_DATA environment variable is set.
