NAME

       hdfpack - compress an HDF file

SYNOPSIS

       hdfpack [-i|-b] [-d data-descriptors-per-block] [-t linked-blocks-per-table-entry] input-
              hdf-file output-hdf-file

DESCRIPTION

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

OPTIONS

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

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

       -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.

EXAMPLES

       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 compressed data to a file named "bb.blk".

               hdfpack -b bb.hdf bb.blk
