DESCRIPTION

16       The main purpose of this utility is to recompress and test the zip  ar‐
17       chives to get the smallest possible size.
18
19       For  recompression  the 7‐Zip (www.7‐zip.com) Deflate implementation is
20       used. This implementation generally gives 5‐10% more  compression  than
21       the zLib Deflate implementation.
22
23       For  experimental  purpose  also  the 7‐Zip LZMA algorithm is available
24       with the ‐N option. In this case, the generated zips WILL NOT BE USABLE
25       by  any  other program. To make them usable you need to recompress them
26       without the ‐N option. Generally this algorithm gives 10‐20% more  com‐
27       pression than the 7‐Zip Deflate implementation.

OPTIONS

30       ‐a, ‐‐add ARCHIVE FILES...
31              Create  the specified archive with the specified files. You must
32              specify only one archive.
33
34       ‐x, ‐‐extract ARCHIVE
35              Extract all the files on the specified archive. You must specify
36              only one archive.
37
38       ‐l, ‐‐list ARCHIVES...
39              List the content of the specified archives.
40
41       ‐z, ‐‐recompress ARCHIVES...
42              Recompress the specified archives. If the ‐1, ‐2, ‐3 options are
43              specified, it’s used the smallest file choice from: the previous
44              compressed  data,  the new compression and the uncompressed for‐
45              mat. If the ‐0 option is specified the archive is always rewrit‐
46              ten without any compression.
47
48       ‐t, ‐‐test ARCHIVES...
49              Test  the specified archives. The tests may be extended with the
50              ‐p option.
51
52       ‐N, ‐‐not‐zip
53              Use the LZMA algorithm when compressing. The generated zips will
54              not be readable by any other application!
55
56       ‐p, ‐‐pedantic
57              Be  pedantic on the zip tests. If this flag is enabled some more
58              extensive tests on the zip integrity are done. These  tests  are
59              generally not done by other zip utilities.
60
61       ‐0, ‐‐shrink‐store
62              Disable  the  compression.  The file is only stored and not com‐
63              pressed. This option is very useful to expand  the  archives  of
64              .png  and .mp3 files. These files are already compressed, trying
65              to compress them another time is really  a  waste  of  time  and
66              resource.
67
68       ‐1, ‐‐shrink‐fast
69              Set the compression level to ˝fast˝.
70
71       ‐2, ‐‐shrink‐normal
72              Set the compression level to ˝normal˝. This is the default level
73              of compression.
74
75       ‐3, ‐‐shrink‐extra
76              Set the compression level to ˝extra˝.
77
78       ‐4, ‐‐shrink‐insane
79              Set the compression level to ˝insane˝.
