hdfpack - compress an HDF file

hdfpack compresses all of the data in an HDF file and writes the compressed data to a second HDF file.

       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 command:

               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  com‐
       pressed data to a file named "bb.blk".

               hdfpack -b bb.hdf bb.blk

-b     Non-coalesced Blocks.  hdfpack will not coalesce linked-block elements.

       -i     Interactive Mode.  hdfpack will prompt for each linked-block element.

       -dnum Write an output file with the specified number of data descriptors per block of data descriptors.

       -tnum Write an output file with the specified number of linked blocks per table entry.
