Dump the content of a GRIB file in different formats.


grib_dump [options] grib_file grib_file ...


Octet mode. WMO documentation style dump.

Debug mode.

Print all data values. Available only in C mode

C code mode. A C code program generating the GRIB message is dumped.

Print type information.

Print octet content in hexadecimal format.

Dump aliases.

-w key[:{s/d/l}]{=/!=}value,key[:{s/d/l}]{=/!=}value,...
Where clause. Grib messages are processed only if they match all the key/value constraints. A valid constraint is of type key=value or key!=value. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be specified. Default type is string.
In the value you can also use the forward-slash character "/" to specify an OR condition (i.e. a logical disjunction)

-s key[:{s/d/i}]=value,key[:{s/d/i}]=value,...
Key/values to set. For each key a string (key:s) or a double (key:d) or an integer (key:i) type can be defined. By default the native type is set.

Multi-field support off. Turn off support for multiple fields in single GRIB message.

-T T | B | A
Message type. T -> GTS, B -> BUFR, A -> Any (Experimental). The input file is interpreted according to the message type.

Does not fail when the message has wrong length


-X offset
Input file offset in bytes. Processing of the input file will start from "offset".

grib_dump examples

  1. To dump in a WMO documentation style with hexadecimal octet values (-H).

    > grib_dump -OH ../data/reduced_gaussian_model_level.grib1
  2. To add key aliases and type information.

    > grib_dump -OtaH ../data/reduced_gaussian_model_level.grib
  3. To obtain all the key names (computed keys included) available in a grib file.

    > grib_dump -D ../data/regular_latlon_surface.grib1
