     NAME
          lzip - reduces the size of files

     SYNOPSIS
          lzip [,options/] [,files/]

     DESCRIPTION
          Lzip is a lossless data compressor with a user interface similar to
          the one of gzip or bzip2. 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.

     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, --member-size=<bytes>
               set member size limit in bytes

          -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]

                                    January 2019

          -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]

          -S, --volume-size=<bytes>
               set volume size limit in bytes

          -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 '-', lzip 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 lzip to panic.
