NAME
minilzip - reduces the size of files
SYNOPSIS
minilzip [options] [files]
DESCRIPTION
Minilzip is a test program for the compression library lzlib, fully 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 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.
OPTIONS
-h, --help display this 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 in bytes -c, --stdout write to standard output, keep input files -d, --decompress decompress -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 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 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), 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).
