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.

       -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).
