💖 HDFPACK — the hdfpack(1) glow-up 💖

okay bestie, gather round, because this is the general commands manual entry for hdfpack, and she is here to squeeze your HDF files down to size. no cap.

✨ 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

like, she takes an input and she gives you an output. that's the whole vibe. 🫶

🌸 DESCRIPTION 🌸

okay so here's the tea: hdfpack compresses all of the data in an HDF file and writes that compressed data to a second HDF file. that's it, that's the job, and she does it flawlessly. 💅

👑 OPTIONS 👑

  • -b — Non-coalesced Blocks. hdfpack will not coalesce linked-block elements. she's leaving them exactly where they are, respectfully. 🛑
  • -i — Interactive Mode. hdfpack will prompt you for each linked-block element. yes, every single one. she wants your input, bestie, she's being thorough. 🙈
  • -d num — Write an output file with the specified number of data descriptors per block of data descriptors. you're picking the number here, so choose wisely. 🔢
  • -t num — Write an output file with the specified number of linked blocks per table entry. again, your call, your numbers. ⭐

🌈 EXAMPLES 🌈

so say you wanna compress the data in the file named "aa.hdf" and store the compressed data in the file named "aa.cmp". run this, periodt:

hdfpack aa.hdf aa.cmp

now imagine a file named "bb.hdf" that contains data elements stored as sequences of linked blocks. this next 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

see how clean that was? iconic behaviour, honestly. 🔥
