NAME

       plzip - reduces the size of files

SYNOPSIS

       plzip [options] [files]

DESCRIPTION

       Plzip  is  a  massively parallel (multi-threaded) implementation of lzip, fully compatible
       with lzip 1.4 or newer. Plzip uses the compression library lzlib.

       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.

       Plzip  can  compress/decompress  large  files  on multiprocessor machines much faster than
       lzip, at the cost of a slightly  reduced  compression  ratio  (0.4  to  2  percent  larger
       compressed  files).  Note  that  the  number of usable threads is limited by file size; on
       files larger than a few GB plzip can use hundreds of processors, but on files  of  only  a
       few MB plzip is no faster than lzip.

              set number of (de)compression threads [2]

       -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]

       -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

       --in-slots=<n>
              number of 1 MiB input packets buffered [4]

       --out-slots=<n>
              number of 1 MiB output packets buffered [64]

       --check-lib
              compare version of lzlib.h with liblz.{a,so}

       If  no  file  names  are given, or if a file is '-', plzip 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 'plzip -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 plzip to panic.
