Lzip - LZMA lossless data compressor.
Usage: lzip [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, --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]
-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
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.
