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 and provides a 3 factor
integrity checking to maximize interoperability and optimize safety. 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.

--fast alias for -0
--best alias for -9
--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 flags, 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), Andrey 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).
