Description

NAME    grib_get

DESCRIPTION

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|i}],key[:{s|d|i}],...      

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.

-F format      

C style format for floating-point values.

-B 'order by' directive

Order by. The output will be ordered according to the 'order by' directive. Example: "step:i asc, centre desc" (step numeric ascending and centre descending) Default sort mode is 'asc'

-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|i}],key[:{s|d|i}],...      

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

-w key[:{s|d|i}]{=|!=}value,key[:{s|d|i}]{=|!=}value,...        

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) Note: only one -w clause is allowed.

-n namespace    

All the keys belonging to namespace are printed.

-s key[:{s|d|i}]=value,key[:{s|d|i}]=value,...  

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.

-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 | M | A

Message type. T->GTS, B->BUFR, M->METAR (Experimental), 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 the given offset.

-i index        

Data value corresponding to the given index is printed.
