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.
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.
