grib_get

DESCRIPTION

Get values of some keys from a grib file. It is similar to grib_ls, but fails returning an error code when an error occurs (e.g. key not found).

USAGE

grib_get [options] grib_file grib_file ...

OPTIONS

-f Force. Force the execution not to fail on error. -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. -F format C style format for floating point values. -l Latitude,Longitude[,MODE,file] Value close to the point of a Latitude/Longitude. Allowed values for MODE are: 4 (4 values in the nearest points are printed) Default 1 (the value at the nearest point is printed) file (file is used as mask. The closer point with mask value>=0.5 is printed) -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. Grib messages are processed only if they match all the key/value constraints. 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 specified. Default type is string. -n namespace All the keys belonging to namespace are printed. -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. -V Version. -W width Minimum width of each column in output. Default is 10. -m Mars keys are printed. -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. -7 Does not fail when the message has wrong length -X offset Input file offset in bytes. Processing of the input file will start from "offset". -i index Data value corresponding to the given index is printed.
