Ubuntu Manpage: lzip - reduces the size of files

NAME

       lzip - reduces the size of files

SYNOPSIS

       lzip [options] [files]

DESCRIPTION

       Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip uses a
       simplified   form   of   the   'Lempel-Ziv-Markov  chain-Algorithm'  (LZMA)  stream  format  to  maximize
       interoperability. The maximum dictionary size is 512 MiB so that any lzip file  can  be  decompressed  on
       32-bit  machines.  Lzip provides accurate and robust 3-factor integrity checking. Lzip can compress about
       as fast as gzip (lzip -0) or compress most files more  than  bzip2  (lzip  -9).  Decompression  speed  is
       intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery perspective.
       Lzip  has  been  designed,  written, and tested with great care to replace gzip and bzip2 as the standard
       general-purpose compressed format for Unix-like systems.

       -m, --match-length=<bytes>
              set match length limit in bytes [36]

       -o, --output=<file>
              write to <file>, keep input files

       -q, --quiet
              suppress all messages

       -s, --dictionary-size=<bytes>
              set dictionary size limit in bytes [8 MiB]

       -S, --volume-size=<bytes>
              set volume size limit in bytes

       -t, --test
              test compressed file integrity

       -v, --verbose
              be verbose (a 2nd -v gives more)

       -0 .. -9
              set compression level [default 6]

       --fast alias for -0

       --best alias for -9

       --empty-error
              exit with error status if empty member in file

       --marking-error
              exit with error status if 1st LZMA byte not 0

       --loose-trailing
              allow trailing data seeming corrupt header

       If no file names are given, or if a file is '-', lzip compresses or decompresses from standard  input  to
       standard  output.  Numbers may be followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024,
       M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...  Dictionary sizes 12 to 29 are interpreted as powers  of
       two, meaning 2^12 to 2^29 bytes.

       The  bidimensional  parameter  space  of LZMA can't be mapped to a linear scale optimal for all files. If
       your files are large, very repetitive, etc, you  may  need  to  use  the  options  --dictionary-size  and
       --match-length directly to achieve optimal performance.

       To  extract  all  the files from archive 'foo.tar.lz', use the commands 'tar -xf foo.tar.lz' or 'lzip -cd
       foo.tar.lz | tar -xf -'.

       Exit status: 0 for a normal exit, 1 for environmental problems  (file  not  found,  invalid  command-line
       options,  I/O  errors, etc), 2 to indicate a corrupt or invalid input file, 3 for an internal consistency
       error (e.g., bug) which caused lzip to panic.

       The ideas embodied in lzip are due to (at least) the following people: Abraham Lempel and Jacob Ziv  (for
       the LZ algorithm), Andrei Markov (for the definition of Markov chains), G.N.N. Martin (for the definition
       of  range  encoding),  Igor  Pavlov  (for putting all the above together in LZMA), and Julian Seward (for
       bzip2's CLI).
