MINILZIP(1)                      User Commands                     MINILZIP(1)

NAME
       minilzip - reduces the size of files

SYNOPSIS
       minilzip [options] [files]

DESCRIPTION
       Minilzip is a test program for the compression library lzlib,
       compatible with lzip 1.4 or newer.

       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.

       -d, --decompress
              decompress, test compressed file integrity

       -f, --force
              overwrite existing output files

       -F, --recompress
              force re-compression of compressed files

       -k, --keep
              keep (don't delete) input files

       -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

       --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).
