grib_copy examples
To copy only the pressure levels from a file
Code Block > grib_copy -w levtype=pl ../data/tigge_pf_ecmwf.grib2 out.grib
To copy only the fields that are not on pressure levels from a file
Code Block > grib_copy -w levtype!=pl ../data/tigge_pf_ecmwf.grib2 out.grib
A grib_file with multi field messages can be converted in single field messages with a simple grib_copy.
Code Block > grib_copy multi.grib simple.grib
Use the square brackets to insert the value of a key in the name of the output file.
