The following command line tools are provided to help users in all interactive and batch processing of GRIB data.

Use of the tools is recommended whenever possible. They provide a ready and tested solution for many situations and their use will avoid the need to write new code and thus will speed up your work.

To make easier their use the tools are provided with a common set of options so that it's quick to apply the same options to different tools. We suggest you begin with grib_dump, grib_ls and grib_get to inspect the content of some files and then to learn about the other tools to change the content of the GRIB message (grib_set, grib_filter) or to copy some messages from a file (grib_copy) or to get a latitude/longitude/values list of data (grib_get_data). A smart compare tool (grib_compare) is also provided to compare GRIB messages focusing on some keys or comparing data with a given precision.


Please note that the tool "grib_convert" is no longer supported. Please use "grib_filter" instead.
