How can I create index files for local GRIB files?

I have some local GRIB files, but they don't have index files. How can I make the .idx file?

Index files can be generated with wgrib2.

wgrib2 -s file.grib2 > file.grib2.idx

If wgrib2 is in your path, Herbie has a helper function to make the index files.

from pathlib import Path
import herbie.wgrib2

# list of grib2 files
files = sorted(Path("/user/data/my_urma_data").rglob("*/urma2p5*wexp"))

# generate an index file for each file
for f in files:
    herbie.wgrib2.create_inventory_file(f)
