grib_keys tool

Kilistázza azokat a kulcsokat, amelyeket a GRIB típusa elérhetővé tesz (-T beállítás), vagy amelyek egy fájlból a GRIB üzenetbe kerülhetnek (-F beállítás).

Használat

grib_ls [beállítások]

Beállítások

-T típus

Kiírja az adott GRIB típusban rendelkezésre álló kulcsokat. A rendelkezésre álló típusok listáját a -L beállításánál láthatod.

-F fájl

Kiírja azokat a kulcsokat, amelyek a GRIB fájlban rendelkezésre állnak.

-x

Kiírja a kiterjesztett kulcstáblázatot.

-c

Csak a kódolt kulcsokat írja ki.

-L

A rendelkezésre álló típusok listája.

-t

Kiírja a típusra vonatkozó információit.

-a

Kidobja a felvett neveket.

5. Kiírjuk azokat a kulcsokat, amelyek az uv500.grib fájlban rendelkezésre állnak úgy, hogy csak a kódolt kulcsokra vagyunk kíváncsiak

A kódolt kulcsok közvetlenül kapcsolódnak a GRIB üzenetek oktetjeihez (nyolc elemből álló adathalmaz), és értékeik csak az oktetek dekódolásával férhető hozzá. Az üzenetben alkalmazott összes kódolt kulcsot a grib_dump parancs segítségével írathatjuk ki.
