9 NAME grib_get
10 DESCRIPTION
12 Get values of some keys from a GRIB file. It is similar to
14 grib_ls, but fails returning an error code when an error occurs
15 (e.g. key not found).
16 USAGE
18 grib_get [options] grib_file grib_file ...
20 OPTIONS
22 -f Force. Force the execution not to fail on error.
24 -p key[:{s|d|i}],key[:{s|d|i}],...
26 Declaration of keys to print. For each key a string (key:s), a
28 double (key:d) or an integer (key:i) type can be requested. De‐
29 fault type is string.
30 -F format
32 C style format for floating-point values.
34 -B 'order by' directive
36 Order by. The output will be ordered according to the 'order by'
38 directive. Example: "step:i asc, centre desc" (step numeric as‐
39 cending and centre descending) Default sort mode is 'asc'
40 -l Latitude,Longitude[,MODE,file]
42 Value close to the point of a Latitude,Longitude. Allowed val‐
44 ues for MODE are:
45 4 (4 values in the nearest points are printed) Default 1 (the
47 value at the nearest point is printed)
48 file (file is used as mask. The closer point with mask
50 value>=0.5 is printed)
51 -P key[:{s|d|i}],key[:{s|d|i}],...
53 As -p adding the declared keys to the default list.
55 -w key[:{s|d|i}]{=|!=}value,key[:{s|d|i}]{=|!=}value,...
57 Where clause. Messages are processed only if they match all the
59 key/value constraints. A valid constraint is of type key=value
60 or key!=value. For each key a string (key:s), a double (key:d)
61 or an integer (key:i) type can be specified. Default type is
62 string. In the value you can also use the forward-slash charac‐
63 ter '/' to specify an OR condition (i.e. a logical disjunction)
64 Note: only one -w clause is allowed.
65 -n namespace
67 All the keys belonging to namespace are printed.
69 -s key[:{s|d|i}]=value,key[:{s|d|i}]=value,...
71 Key/values to set. For each key a string (key:s), a double
73 (key:d) or an integer (key:i) type can be defined. By default
74 the native type is set.
75 -V Version.
77 -W width
79 Minimum width of each column in output. Default is 10.
81 -m Mars keys are printed.
83 -M Multi-field support off. Turn off support for multiple fields in
85 single GRIB message.
86 -g Copy GTS header.
88 -G GRIBEX compatibility mode.
90 -T T | B | M | A
92 Message type. T->GTS, B->BUFR, M->METAR (Experimental), A->Any
93 (Experimental). The input file is interpreted according to the
94 message type.
95 -7 Does not fail when the message has wrong length
97 -X offset
99 Input file offset in bytes. Processing of the input file will
101 start from the given offset.
102 -i index
104 Data value corresponding to the given index is printed.
