lrz man page

lrz — gzip compatible command line variant of lrzip


lrz [OPTIONS] <file>


lrz is identical to the lrzip application however its command line options and behaviour are made to be as compatible with gzip as possible.


lrz differs from lrzip by accepting the following commands:

General options:
-c, --stdout output to STDOUT
-C, --check check integrity of file written on decompression
-d, --decompress decompress
-e, --encrypt password protected sha512/aes128 encryption on compression
-h, -?, --help show help
-H, --hash display md5 hash integrity information
-i, --info show compressed file information
-L, --license display software version and license
-P, --progress show compression progress
-r, --recursive operate recursively on directories
-t, --test test compressed file integrity
-v[vv], --verbose Increase verbosity
-V, --version show version Options affecting output:
-f, --force force overwrite of any existing files
-k, --keep don't delete source files on de/compression
-K, --keep-broken keep broken or damaged output files
-o, --outfile filename specify the output file name and/or path
-O, --outdir directory specify the output directory when -o is not used
-S, --suffix suffix specify compressed suffix (default '.lrz') Options affecting compression:
-b, --bzip2 bzip2 compression
-g, --gzip gzip compression using zlib
-l, --lzo lzo compression (ultra fast)
-n, --no-compress no backend compression - prepare for other compressor
-z, --zpaq zpaq compression (best, extreme compression, extremely slow) Low level options:
-1 .. -9 set lzma/bzip2/gzip compression level (1-9, default 7)
--fast alias for -1
--best alias for -9
-L, --level level set lzma/bzip2/gzip compression level (1-9, default 7)
-N, --nice-level value Set nice value to value (default 0)
-p, --threads value Set processor count to override number of threads
-m, --maxram size Set maximim available ram in hundreds of MB
overrides detected ammount of available ram
-T, --threshold Disable LZO compressibility testing
-U, --unlimited Use unlimited window size beyond ramsize (potentially much slower)
-w, --window size maximum compression window in hundreds of MB
default chosen by heuristic dependent on ram and chosen compression
