# grib\_set(1)

## NAME

grib\_set

## DESCRIPTION

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.
