advzip - AdvanceCOMP ZIP Compression Utility
SYNOPSIS
advzip [-a, --add] [-x, --extract] [-l, --list]
[-z, --recompress] [-t, --test] [-0, --shrink-store]
[-1, --shrink-fast] [-2, --shrink-normal] [-3, --shrink-extra]
[-4, --shrink-insane] [-i, --iter N]
[-k, --keep-file-time] [-p, --pedantic] [-q, --quiet]
[-h, --help] [-V, --version] ARCHIVES... [FILES...]
DESCRIPTION
The main purpose of this utility is to recompress and test the zip archives to get the
smallest possible size.
For recompression the 7-Zip (www.7-zip.com) Deflate implementation is used. This
implementation generally gives 5-10% more compression than the zLib Deflate
implementation.
For experimental purpose also the 7-Zip LZMA algorithm is available with the -N option. In
this case, the generated zips WILL NOT BE USABLE by any other program. To make them usable
you need to recompress them without the -N option. Generally this algorithm gives 10-20%
more compression than the 7-Zip Deflate implementation.
OPTIONS
-a, --add ARCHIVE FILES...
Create the specified archive with the specified files. You must specify only one
archive.
-x, --extract ARCHIVE
Extract all the files on the specified archive. You must specify only one archive.
-l, --list ARCHIVES...
List the content of the specified archives.
-z, --recompress ARCHIVES...
Recompress the specified archives. If the -1, -2, -3, -4 options are specified,
it´s used the smallest file choice from: the previous compressed data, the new
compression and the uncompressed format. If the -0 option is specified the archive
is always rewritten without any compression.
-t, --test ARCHIVES...
Test the specified archives. The tests may be extended with the -p option.
-k, --keep-file-time
When recompressing with -z keep the .zip file time.
-p, --pedantic
Be pedantic on the zip tests. If this flag is enabled some more extensive tests on
the zip integrity are done. These tests are generally not done by other zip
utilities.
-0, --shrink-store
Disable the compression. The file is only stored and not compressed. This option is
very useful to expand the archives of .png and .mp3 files. These files are already
compressed, trying to compress them another time is really a waste of time and
resource.
-1, --shrink-fast
Set the compression level to "fast" using the zlib compressor.
-2, --shrink-normal
Set the compression level to "normal" using the 7z compressor. This is the default
level of compression.
-3, --shrink-extra
Set the compression level to "extra" using the 7z compressor. You can define the
compressor iterations with the -i, --iter option.
-4, --shrink-insane
Set the compression level to "insane" using the zopfli compressor. You can define
the compressor iterations with the -i, --iter option.
-i, --iter N
Define an additional numer of iterations for the 7z and zopfli compressors for
modes -3 and -4. More iterations usually give a better compression, but may
require a lot more time. Try for example with 10, 15, 20, and so on.
