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).
grib_set [options] grib_file grib_file ... output_grib_file
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.
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.
Set all the data values to "value".
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.
As -p adding the declared keys to the default list.
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. 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.
Does not fail when the message has wrong length
Strict. Only grib messages matching all the constraints are copied to the output file
Version.
Multi-field support off. Turn off support for multiple fields in single grib message.
Copy GTS header.
GRIBEX compatibility mode.
Message type. T->GTS, B->BUFR, A->Any (Experimental). The input file is interpreted according to the message type.
Force. Force the execution not to fail on error.
Verbose.
