Ubuntu Manpage: minilzip - reduces the size of files

NAME

       minilzip - reduces the size of files

SYNOPSIS

       minilzip [options] [files]

DESCRIPTION

       Minilzip  is  a  test program for the compression library lzlib. Minilzip is not intended to be installed
       because lzip has more features, but minilzip is well tested and you can use it as your main compressor if
       so you wish.

       Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip uses a
       simplified form of LZMA (Lempel-Ziv-Markov chain-Algorithm) designed to achieve complete interoperability
       between implementations. 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  -0'  compresses
       about  as  fast  as  gzip,  while 'lzip -9' compresses most files more than bzip2. Decompression speed is
       intermediate between gzip and bzip2. Lzip provides better data recovery capabilities than gzip and bzip2.
       Lzip has been designed, written, and tested with great care to replace gzip and bzip2 as  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

       -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

       --loose-trailing
              allow trailing data seeming corrupt header

       --check-lib
              compare version of lzlib.h with liblz.{a,so}

       If  no file names are given, or if a file is '-', minilzip 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  'minilzip
       -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 minilzip to panic.

       The ideas embodied in lzlib 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).
