NAME

       pdlzip - reduces the size of files

SYNOPSIS

       pdlzip [options] [files]

DESCRIPTION

       Pdlzip is a permissively licensed implementation of the lzip data compressor, intended for
       those who can't distribute (or even use) GPL licensed Free Software. The  name  of  pdlzip
       comes  from  'public  domain  lzip'.  Pdlzip is written in C and is (hope)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.

       Pdlzip  is  also able to decompress legacy lzma-alone (.lzma) files.  Lzma-alone is a very
       bad format; it is essentially a raw LZMA stream.  If you keep any lzma-alone files, it  is
       advisable to recompress them to lzip format. Lziprecover can convert some lzma-alone files
       to lzip format without recompressing.

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

       -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]

       -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 '-', pdlzip 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 27 are interpreted as powers of two, meaning 2^12 to 2^27 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. For example,
       -9m64 usually compresses executables more (and faster) than -9.

       To extract all the files from archive 'foo.tar.lz', use the commands 'tar -xf  foo.tar.lz'
       or 'pdlzip -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 pdlzip to panic.

       Pdlzip  includes  public domain compression/decompression code from the LZMA SDK (Software
       Development Kit) written by Igor Pavlov.
