LZIP(1)                          User Commands                         LZIP(1)


NAME

       lzip - reduces the size of files


SYNOPSIS

       lzip [options] [files]


DESCRIPTION

       Lzip - LZMA lossless data compressor.


OPTIONS

       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

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

       -c, --stdout
              send output to standard output

       -d, --decompress
              decompress

       -f, --force
              overwrite existing output files

       -F, --recompress
              force recompression 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]

       -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

       If no file names are given, 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...  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 lzip to panic.
