Dump the content of a grib file in different formats.<h2><a class="anchor" name="USAGE">
USAGE</a></h2>
grib_dump [options] grib_file grib_file ...<h2><a class="anchor" name="OPTIONS">
OPTIONS</a></h2>
-O <br>
Octet mode. WMO documentation style dump. <br>
<br>
-D <br>
Debug mode. <br>
<br>
-P key[:{s/d/l}],key[:{s/d/l}],... <br>
As -p adding the declared keys to the default list. <br>
<br>
-d <br>
Print all data values. Available only in C mode <br>
<br>
-C <br>
C code mode. A C code program generating the grib message is dumped. <br>
<br>
-t <br>
Print type information. <br>
<br>
-H <br>
Print octet content in hexadecimal format. <br>
<br>
-a <br>
Dump aliases. <br>
<br>
-w key[:{s/d/l}]{=/!=}value,key[:{s/d/l}]{=/!=}value,... <br>
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. <br>
<br>
-M <br>
Multi-grib support off. Turn off support for multiple fields in single grib message <br>
<br>
-7 <br>
Does not fail when the message has wrong length <br>
<br>
-V <br>
Version. <br>
<br>
-G <br>
GRIBEX compatibility mode. <br>
