grib_set1

Overview

Sets key/value pairs in the input grib file and writes each message to the output_grib_file. It fails when an error occurs (e.g. key not found).

Usage

grib_set [options] grib_file grib_file ... output_grib_file

Options

-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.

-r Repack data. Sometimes after setting some keys involving properties

of the packing algorithm a repacking of data is needed. This repacking is performed setting this -r option.

-d value

Set all the data values to "value".

-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.

-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. Set is only executed for grib messages matching all the key/value constraints. If a grib message does not match the constraints it is copied unchanged to the output_grib_file. This behaviour can be changed setting the option -S. 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 defined. Default type is string.

-7 Does not fail when the message has wrong length

-S Strict. Only grib messages matching all the constraints are copied to

the output file

-V Version.

-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.

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

-v Verbose.
