Introduction

The -set_metadata_str "string" option is similar to the older -set_metadata FILE option. Instead of reading the metadata from a file, the metadata is on the command line. The latter option is generally more useful as each grib message can have its own set of metadata. The former option is only useful for specifying the metadata for a single grib message. The -set_metadata_str option was added to facilitate the creation of an "callable wgrib2" API for writing grib2. See -set_metadata for the format of the metadata string.

Usage:

-set_metadata_str "metadata"
metadata is a string 

Example:

sh-4.1$ wgrib2 small.grb2  -set_metadata_str "1:0:d=2001020304:TMP:10 mb:anl:"
1:0:d=2001020304:TMP:10 mb:anl:ENS=+19
