grib_get1

Overview

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).

Usage

grib_get [options] grib_file grib_file ...

Options

-f Force. Force the execution not to fail on error.

-p key[:{s/d/l}],key[:{s/d/l}],...

Declaration of keys to print. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be requested. Default type is string.

-F format

C style format for floating point values.

-l Latitude,Longitude[,MODE,file]

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)

-P key[:{s/d/l}],key[:{s/d/l}],...

As -p adding the declared keys to the default list.

-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.

-n namespace

All the keys belonging to namespace are printed.

-s key[:{s/d/l}]=value,key[:{s/d/l}]=value,...

Key/values to set. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be defined. By default the native type is set.

-V Version.

-W width

Minimum width of each column in output. Default is 10.

-m Mars keys are printed.

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

-g Copy GTS header.

-G GRIBEX compatibility mode.

-T T | B | A Message type. T->GTS, B->BUFR, A->Any (Experimental).

The input file is interpreted according to the message type.

-7 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".

-i index

Data value corresponding to the given index is printed.
