If you replace '-v' with '-V', you should see definitions and data only for the variable (column_amount) that you are interested in. The tools provided by Unidata (nccopy, ncgen, ncdump) do not offer batch operations, but there are other tools that might be able to do what you're looking for. I'd suggest looking at the NetCDF Operators (NCO) software package.
