NAME

       clzip - reduces the size of files

SYNOPSIS

       clzip [options] [files]

DESCRIPTION

       Clzip  is  a C language version of lzip, fully compatible with lzip 1.4 or newer. As clzip
       is written in C, it may be easier to integrate  in  applications  like  package  managers,
       embedded devices, or 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  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.

              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

       -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
       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 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), 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).
