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.

              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).
