Get values of some keys from a grib file. It is similar to grib_ls, but fails returning an error code when an error occurs (e.g. key not found).
grib_get [options] grib_file grib_file ...
Force. Force the execution not to fail on error.
Declaration of keys to print. For each key a string (key:s), a double (key:d) or an integer (key:i) type can be requested. Default type is string.
C style format for floating point values.
Value close to the point of a Latitude/Longitude. Allowed values for MODE are: 4 (4 values in the nearest points are printed) Default 1 (the value at the nearest point is printed) file (file is used as mask. The closer point with mask value>=0.5 is printed)
As -p adding the declared keys to the default list.
Where clause. 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), a double (key:d) or an integer (key:i) 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)
All the keys belonging to namespace are printed.
Key/values to set. For each key a string (key:s), a double (key:d) or an integer (key:i) type can be defined. By default the native type is set.

Input file offset in bytes. Processing of the input file will start from "offset".
Data value corresponding to the given index is printed.

> grib_get -p gribname ../data/tigge_pf_ecmwf.grib2 |
