/usr/bin/lzip

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) and is 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.

Usage: /usr/bin/lzip [options] [files]

Options:
  -h                             display usage help and exit
      --help                     display full help and exit
  -V, --version                  output version information and exit
  -a, --trailing-error           exit with error status if trailing data
  -b, --member-size=<bytes>      set member size limit of multimember files
  -c, --stdout                   write to standard output, keep input files
  -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
  -l, --list                     print (un)compressed file sizes
  -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]
      --loose-trailing           allow trailing data seeming corrupt header

Lzip replaces each named file with a (de)compressed version.
If no file names are given, or if a file is '-', lzip compresses or
decompresses from standard input to standard output.
Numbers may contain underscore separators between groups of digits and
may be followed by a SI or binary multiplier: 1_234_567kB, 4KiB.
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 -'.

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).

*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.
