DBZ2(1)

📦 version 0.12, in nixpkgs unstable

💅 dbz2 — the distributed bz2 compression girlie

okay so this is dbz2(1) from the mpiFileUtils gang, and bestie, she's here to compress (or decompress) your files across a whole MPI fleet. no cap.

✨ SYNOPSIS ✨

dbz2 [OPTIONS] [-z|-d] FILE

like literally that's it. options, then pick your fighter (-z or -d), then the file. periodt.

🦋 DESCRIPTION 🦋

dbz2 is a parallel MPI application that compresses or decompresses a file. so instead of one sad little core chugging through your data, you get the whole squad. main character energy fr.

When compressing, a new file will be created with a .dbz2 extension. 👑

When decompressing, the .dbz2 extension will be dropped from the file name. so cute, so tidy.

🎀 OPTIONS 🎀

  • -z, --compress — compress the file, slay 💖
  • -d, --decompress — decompress the file, reverse slay 💜
  • -k, --keep — keep the input file around (don't ghost it)
  • -f, --force — overwrite the output file if it already exists, no questions asked
  • -b, --blocksize SIZE — set the compression block size, from 1 to 9. where 1=100kB ... and 9=900kB. Default is 9. big block energy 🌸
  • -v, --verbose — verbose output (optional). she talks 🗣️
  • -q, --quiet — quiet output. she does not talk 🤫
  • -h, --help — print usage. the classic cry for help ✨
ngl the block size thing is a real vibe check: 1 through 9 only, and 1=100kB all the way up to 9=900kB, default 9. don't try to be cute with other numbers.

🧚 EXAMPLES 🧚

  1. To compress a file:
mpirun -np 128 dbz2 --compress /path/to/file
  1. To compress a file and overwrite any existing output file:
mpirun -np 128 dbz2 --force --compress /path/to/file
  1. To decompress a file:
mpirun -np 128 dbz2 --decompress /path/to/file.dbz2
