- Select the section you want the dump for. For example for section 1 you use the key "section_1"
- Invoke "grib_dump -p $key" on the given key
To find out the sections of each edition, see here:
For example let's look at the grid section Grid Section of a GRIB edition 1 file. This would be section Section 2 for edition 1

% grib_dump -p section_2 data/regular_latlon_surface.grib1
====================== SECTION_2 ( length=32, padding=0 ) ======================

And now let's dump the Product Section for a GRIB edition 2 message. This would be Section 4:
