hdfpack - compress an HDF file
hdfpack [-i|-b] [-d data-descriptors-per-block] [-t linked-blocks-per-
table-entry] input-hdf-file output-hdf-file
hdfpack compresses all of the data in an HDF file and writes the
compressed data to a second HDF file.
-b Non-coalesced Blocks. hdfpack will not coalesce linked-block
-i Interactive Mode. hdfpack will prompt for each linked-block
-d num Write an output file with the specified number of data
descriptors per block of data descriptors.
-t num Write an output file with the specified number of linked blocks
per table entry.
To compress the data in the file named "aa.hdf" and store the
compressed data in the file named "aa.cmp", use the following hdfpack
hdfpack aa.hdf aa.cmp
Suppose a file named "bb.hdf" contains data elements stored as
sequences of linked blocks. The following hdfpack command compresses
the file while leaving the linked-block elements intact, and writes the
compressed data to a file named "bb.blk".
hdfpack -b bb.hdf bb.blk
