 NAME
      plzip - reduces the size of files

 SYNOPSIS
      plzip [,options/] [,files/]

 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

      -B, --data-size=<bytes>
           set size of input data blocks [2x8=16 MiB]

      -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

      -l, --list
           print (un)compressed file sizes

      -m, --match-length=<bytes>
           set match length limit in bytes [36]

      -n, --threads=<n>
           set number of (de)compression threads [2]

      -o, --output=<file>
           if reading standard input, write to <file>

                                 April 2017



      -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

      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 --dictionary-size and --match-length
      options directly to achieve optimal performance.

      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 plzip to panic.
