LRZ.1(1)

🌸 NAME 🌸

welcome to LRZ.1(1), the lrz page from User Contributed Perl Documentation 💅

lrz — gzip compatible command line variant of lrzip. That’s the whole vibe.

✨ SYNOPSIS ✨

lrz [options] file

🦋 DESCRIPTION 🦋

okay so lrz is literally identical to the lrzip application, but its command line options and behaviour are made to be as compatible with gzip as possible. no cap, that’s the main character energy here 💖

🎀 OPTIONS 🎀

✨ General options ✨

• --stdout, -c — output to STDOUT.
• --check, -C — check integrity of file written on decompression.
• --decompress, -d — decompress.
• --encrypt[=password], -e — password protect sha512/aes128 encryption on compression.
• --help, -h, -? — show help.
• --hash, -H — display md5 hash integrity information.
• --info, -i — show compressed file information.
• --license, -L — display software version and license.
• --progress, -P — show compression progress.
• --recursive, -r — operate recursively on directories.
• --test, -t — test compressed file integrity.
• --verbose, -v[vv] — increase verbosity.
• --version, -V — show version.

🎀 Options affecting output 🎀

• --force, -f — force overwrite of any existing files.
• --keep, -k — don’t delete source files on de/compression.
• --keep-broken, -K — keep broken or damaged output files.
• --outfile name, -o name — specify the output file name and/or path.
• --outdir dir, -O dir — specify the output directory when -o is not used.
• --suffix suffix, -S suffix — specify compressed suffix (default '.lrz').

--force means force overwrite, bestie. literally what it says. proceed with intention 💀

🔥 Options affecting compression 🔥

• --bzip2, -b — Bzip2 compression.
• --gzip, -g — Gzip compression using zlib.
• --lzo, -l — Lzo compression (ultra fast).
• --lzma — Lzma compression (default).
• --no-compress, -n — no backend compression — prepare for other compressor.
• --zpaq, -z — Zpaq compression (best, extreme compression, extremely slow).

🧚 Low level options 🧚

• -1 .. -9 — yep, literally the -1 through -9 flags, bestie.
• --level level, -L level — set lzma/bzip2/gzip compression level (1-9, default 7).
• --fast — alias for -1.
• --best — alias for -9.
• --nice-level value, -N value — set nice value to value (default 0).
• --threads value, -P value — set processor count to override number of threads.
• --maxram size, -m size — set maximum available ram as size * 100 MB. Overrides detected amount of available ram.
• --threshold, -T — disable LZ4 compressibility testing.
• --unlimited, -U — use unlimited window size beyond ramsize (potentially much slower).
• --window size, -w size — set maximum compression window as size * 100 MB. Default chosen by heuristic dependent on ram and chosen compression.
