NAME

       pdlzip - reduces the size of files

SYNOPSIS

       pdlzip [options] [files]

DESCRIPTION

       Pdlzip  -  A  permissively  licensed  implementation  of the lzip data compressor 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>
              if reading standard input, write to <file>

       -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)

       -1 .. -9
              set compression level [default 6]

       --fast alias for -1

       --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 --dictionary-size and --match-length
       options directly to achieve optimal performance. For example, -9m64 usually compresses  executables  more
       (and faster) than -9.

       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  (eg,
       bug) which caused pdlzip to panic.
