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.
