Hi Konrad,
h5dump with the -p option may give you what you want Combining it with -H will
rmove the data from the output, or add -d to limit the output to a specific
dataset or -g for a specific group. The output for a dataset looks like this:
DATASET "BeamLatitude" {
DATATYPE H5T_IEEE_F32BE
DATASPACE SIMPLE { ( 24, 96, 5 ) / ( H5S_UNLIMITED, H5S_UNLIMITED,
H5S_UNLIMITED
) }
STORAGE_LAYOUT {
CHUNKED ( 12, 48, 5 )
SIZE 46080
}
FILTERS {
NONE
}
FILLVALUE {
FILL_TIME H5D_FILL_TIME_IFSET
VALUE -999.3
}
ALLOCATION_TIME {
H5D_ALLOC_TIME_INCR
}
}
SIZE is the storage size of the dataset in bytes. If the dataset is
compressed, the storage size is the size of the compressed data.

Subject: [Hdf-forum] Finding the size of the datasets in a file
Hi everyone,
I just spent some time looking for a command-line tool that shows the size
occupied by each dataset in a file. I didn't find anything. The most promising
candidates were h5stat, h5ls, and h5dump, but it seems that none of them can
provide the information I am looking for.
Is there perhaps a third-party tool for that purpose?
I realize that "size" can be defined in lots of ways, but I don't really care
about the details. I have lots of files that each contain hundreds of datasets,
of which most are small but a few are very big.
I am looking for a simple way to identify the big ones. My ideal definition of
size is "how much smaller would the file be if dataset X were not in there".
Konrad.
