OpenOffice Calc is very usefull for working with *.dbf files. The only
restrictions – you must not add, rearrange or delete rows.
I'm not looking for a solution to delete a dbf column. I thought that with
GDAL 1.9 I could use QGIS standard interface without any extension or
external software.
Best regards,
Andrea

Andrea,
I recently had a problem of converting a very large shapefile and
include some coordinate data in the file. In the end I was directed to
and successfully used the following command (albeit in a bash file).
The point is that if you can use SQL you can send only those fields you
want to the duplicate file. Hence, albeit with a little programming, you
could 'leave out' the field you want to delete and make a copy of the
file. I know ogr2ogr can be programmed can be handed stuff in python so
an sql command can be constructed and handed to the library as
parameter. To get specifics try the gdal forums.
ogr2ogr -sql "SELECT OGR_GEOM_WKT AS GEOM_WKT, * FROM $FileName" ./dbf
$TheFile
