GRIB_SET(1) User Commands GRIB_SET(1)




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


-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.
