NAME

       pdlzip - reduces the size of files

SYNOPSIS

       pdlzip [options] [files]

DESCRIPTION

       Pdlzip  -  A  "public  domain" version of the lzip data compressor also able to decompress
       legacy lzma-alone (.lzma) files.  Lzma-alone is  a  very  bad  format.  If  you  keep  any
       lzma-alone files, it is advisable to recompress them to lzip format.

OPTIONS

       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -c, --stdout
              send output to standard output

       -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 stdin, place the output into <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

       If  no  file  names  are  given,  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...  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 --match-length and
       --dictionary-size 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.
