NAME

6       lzip - reduces the size of files
7

SYNOPSIS

9       lzip [options] [files]
10

DESCRIPTION

12       Lzip is a lossless data compressor with a user interface similar to the
13       one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0)
14       or  compress  most files more than bzip2 (lzip -9). Decompression speed
15       is intermediate between gzip and bzip2. Lzip is better  than  gzip  and
16       bzip2 from a data recovery perspective. Lzip has been designed, written
17       and tested with great care to replace gzip and bzip2  as  the  standard
18       general-purpose compressed format for unix-like systems.

OPTIONS

21       -h, --help
22              display this help and exit
23
24       -V, --version
25              output version information and exit
26
27       -a, --trailing-error
28              exit with error status if trailing data
29
30       -b, --member-size=<bytes>
31              set member size limit in bytes
32
33       -c, --stdout
34              write to standard output, keep input files
35
36       -d, --decompress
37              decompress
38
39       -f, --force
40              overwrite existing output files
41
42       -F, --recompress
43              force re-compression of compressed files
44
45       -k, --keep

47
48       -l, --list
49              print (un)compressed file sizes
50
51       -m, --match-length=<bytes>
52              set match length limit in bytes [36]
53
54       -o, --output=<file>
55              if reading standard input, write to <file>
56
57       -q, --quiet
58              suppress all messages
59
60       -s, --dictionary-size=<bytes>
61              set dictionary size limit in bytes [8 MiB]
62
63       -S, --volume-size=<bytes>
64              set volume size limit in bytes
65
66       -t, --test
67              test compressed file integrity
68
69       -v, --verbose
70              be verbose (a 2nd -v gives more)
71
72       -0 .. -9
73              set compression level [default 6]
74
75       --fast alias for -0
76
77       --best alias for -9
78
79       --loose-trailing
80              allow trailing data seeming corrupt header
81
82       If  no  file  names  are given, or if a file is '-', lzip compresses or
83       decompresses from standard input to standard output.   Numbers  may  be
84       followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024,
85       M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...  Dictionary  sizes  12
86       to 29 are interpreted as powers of two, meaning 2^12 to 2^29 bytes.
87
88       The  bidimensional  parameter space of LZMA can't be mapped to a linear
89       scale optimal for all files. If your files are large, very  repetitive,
90       etc,  you  may  need  to  use  the --dictionary-size and --match-length
91       options directly to achieve optimal performance.
92
93       Exit status: 0 for a normal exit, 1 for  environmental  problems  (file
94       not  found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
95       invalid input file, 3 for an internal consistency error (eg, bug) which
96       caused lzip to panic.
