NAME

       clzip - reduces the size of files

SYNOPSIS

       clzip [options] [files]

DESCRIPTION

       Clzip is a C language version of lzip intended for systems lacking a C++ compiler.

       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.

       -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]

       --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 '-', clzip 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 'clzip -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 clzip to panic.

       The ideas embodied in clzip 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).
