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

-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

-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.
