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.

General options
Output to STDOUT. Check integrity of file written on decompression. Decompress. Password protect sha512/aes128 encryption on compression. Show help. Display md5 hash integrity information. Show compressed file information. Display software version and license. Show compression progress. Operate recursively on directories. Test compressed file integrity. Increase verbosity. Show version.

Options affecting output
Force overwrite of any existing files. Don't delete source files on de/compression. Keep broken or damaged output files. Specify the output file name and/or path. Specify the output directory when -o is not used. Specify compressed suffix (default '.lrz').

Options affecting compression
Bzip2 compression. Gzip compression using zlib. Lzo compression (ultra fast). Lzma compression (default). No backend compression - prepare for other compressor. Zpaq compression (best, extreme compression, extremely slow).

Low level options
Set lzma/bzip2/gzip compression level (1-9, default 7). Alias for -1. Alias for -9. Set nice value to value (default 0). Set processor count to override number of threads. Set maximum available ram as size * 100 MB. Overrides detected amount of available ram. Disable LZ4 compressibility testing. Use unlimited window size beyond ramsize (potentially much slower). Set maximum compression window as size * 100 MB. Default chosen by heuristic dependent on ram and chosen compression.
