NAME
       lrz - gzip compatible command line variant of lrzip

SYNOPSIS
       lrz [options] file

       possible.

       --decompress
       -d       Decompress.

       --encrypt[=password]
       -e       Password protect sha512/aes128 encryption on compression.

       -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').

   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
       --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.
