1. Without options a default list of keys is printed. The default list is different depending on the type of grib message.

   Code Block

   >>

   > grib_ls ../data/reduced*.grib1 ../data/regular*.grib1 ../data/reduced*.grib2




2. To print offset and count number in file use the keys offset and count Also the total count in a set of files is available as countTotal

   Code Block

   >>

   > grib_ls -p offset,count,countTotal ../data/reduced*.grib1




3. To list only a subset of messages use the -w (where option). Only the pressure levels are listed with the following line.

   Code Block

   >>

   > grib_ls -w levelType=pl ../tigge_pf_ecmwf.grib2




4. All the grib messages not on pressure levels are listed as follows:

   Code Block

   >>

   > grib_ls -w levelType!=pl ../tigge_pf_ecmwf.grib2




5. To get the closest grid point to a latitude/longitude.

   Code Block

   > grib_ls -l 51.46,-1.33,1 -p paramId,name ../data/reduced_gaussian_surface.grib2 ../data/reduced_gaussian_surface.grib2 paramId shortName value 167 2t 282.002 1 of 1 grib messages in ../data/reduced_gaussian_surface.grib2 1 of 1 total grib messages in 1 files Input Point: latitude=51.46 longitude=-1.33 Grid Point chosen #3 index=749 latitude=51.63 longitude=0.00 distance=93.81 (Km) Other grid Points - 1 - index=845 latitude=48.84 longitude=0.00 distance=306.86 (Km) - 2 - index=944 latitude=48.84 longitude=356.40 distance=333.66 (Km) - 3 - index=749 latitude=51.63 longitude=0.00 distance=93.81 (Km) - 4 - index=844 latitude=51.63 longitude=356.25 distance=168.37 (Km)
