Unzip will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. Unzip is compatible with archives created by PKWARE's PKZIP, but in many cases the program options or default behaviors differ. Zipinfo lists technical information about files in a ZIP archive, most commonly found on MS-DOS systems. Such information includes file access permissions, encryption status, type of compression, version and operating system or file system of compressing program, and the like. Funzip acts as a filter; that is, it assumes that a ZIP archive is being piped into standard input, and it extracts the first member from the archive to stdout. If there is an argument, then the input comes from the specified file instead of from stdin. Unzipsfx is a modified version of unzip designed to be prepended to existing ZIP archives in order to form self-extracting archives. Instead of taking its first non-flag argument to be the zipfile(s) to be extracted, unzipsfx seeks itself under the name by which it was invoked and tests or extracts the contents of the appended archive.

6.10a00 (5 Jul 2010):
|
|
- Copy over UnZip 6.00 and rename as UnZip 6.10a00. [EG]
|
|
|
|
6.10a01 (5 Jul 2010):
|
|
- No feature changes.
|
|
|
|
6.10a02 (10 Jul 2010):
|
|
- Add new command parser code from new-cmdparser/unz6-newcmdparser-diffs.txt,
|
|
which is a modified version of the new Zip parser. Some modifications to
|
|
account for changes in UnZip since code was written. UnZip now supports
|
|
use of get_option() to parse the command line, adding support for a
|
|
command table and long options. Command parsing now mostly similar to
|
|
that used in Zip, but most of UnZip syntax preserved. One big difference
|
|
is inverting an option (making negative) is now done by a trailing "-"
|
|
instead of a leading one. See the long help and the manual for the
|
|
current syntax of these and all commands. (unzip.c, unzpriv.h, zipinfo.c,
|
|
vms/cmdline.c) [EG]
|
|
- Changed zipgrep to cope with the new command parser. Added environment
|
|
variable ZIPGREP_UNZIP to let the user specify a particular UnZip program
|
|
to use. (unix/zipgrep) [SMS]
|
|
- Add new option --license to show the license and note added to short help
|
|
displayed when no command arguments that this new option exists. Allows
|
|
distribution of UnZip under the current Info-ZIP license without additional
|
|
documentation. Calls show_license(). (unzip.c) [EG]
|
|
- Add preliminary support for AppleDouble storage of resource information on
|
|
Mac platforms. (extract.c, fileio.c, globals.h, unzip.c, unzip.h,
|
|
unzpriv.h, unix/unix.c) [SMS]
|
|
- Add VMS symlink works check. (extract.c) [SMS]
|
|
- Add new option --options to show all available options. (unzip.c) [EG]
|
|
- Add strerror() if port does not have one. Add check for mbstr.h.
|
|
(unzpriv.h, unix/configure, unix/unix.c) [SMS]
|
|
- Add uname calls to get system identification. (unix/configure, unix/unix.c)
|
|
[SMS]
|
|
- Add control of UID/GID and SGID using X_flag and K_flag. (unix/unix.c,
|
|
vms/vms.c) [SMS]
|
|
- Add verbose report. (vms/cmdline.c, vms/unz_cli.cld) [SMS]
|
|
- Update VMS notes. (vms/notes.txt) [SMS]
|
|
- VMS return code updates and allow restoring old status codes. (vms/vms.c)
|
|
[SMS]
|
|
|
|
6.10a03 (30 Jul 2010):
|
|
- fnfilter() now converts to a wide character string and does the isprint()
|
|
check on that, avoiding the issue of doing the check on multi-byte
|
|
characters. (extract.c, win32/win32.c, unzpriv.h, process.c) [EG]
|
|
- Update TODO list. (ToDo) [EG]
|
|
|
|
6.10a04 (5 Aug 2010):
|
|
- Updated INSTALL with latest information. [SMS]
|
|
- Remove 8-bit ASCII characters from ToDo. Add items. [SMS]
|
|
- Add ZipInfo "C" option to command table. (unzip.c) [SMS]
|
|
- Add new option --commandline to show the processed command line and exit.
|
|
Add new function show_commandline(). Update extended help. (unzip.c,
|
|
fileio.c, unzip.h, zipinfo.c) [EG]
|

|
|
|
6.10a07 (10 Aug 2010):
|
|
- Add announcement file. (unzip610a.ann) [EG]
|
|
- Replace /[NO]CASE_INSENSITIVE with /CASE_MATCH. (vms/unzip_cli.help,
|
|
vms/unz_cli.cld) [SMS]
|
|
|
|
6.10a (23 Aug 2010):
|
|
- Add note to README. Update announcement. (README, unzip610a.ann) [EG]
|
|
|
|
6.10b01 (12 Sep 2010):
|
|
- Restore full Windows Unicode support based on diff in win32-experimental
|
|
directory. Mainly involved adding wide character OS calls to Windows
|
|
port code. WIN32_WIDE must be defined for the new code to be used, but
|
|
this should be the default on Windows platforms from NT on. Currently
|
|
Windows 9x Unicode is partially supported, but this support may be pulled
|
|
to clean up the code. Some of the new functions include check_for_newerw()
|
|
has_win32_wide(), wchar_to_wide_string(), wchar_to_local_string(),
|
|
iswildw(), zstat_win32w(), getNTfiletimeW(), defer_dir_attribsw(),
|
|
set_direc_attribsw(), FStampIsLocTimeW(), mapnamew(), checkdirw(),
|
|
NTQueryVolInfoW(), maskDOSdevicew(), extract_or_test_entrylistw(), and
|
|
map2fatw(). (extract.c, fileio.c, process.c, match.c, globals.h, unzip.c,

|
6.10b02 (16 Sep 2010):
|
|
- Implement -I (--iso-char-set) and -O (--oem-char-set) options to allow user
|
|
to set a specific ISO or OEM character set that UnZip should translate
|
|
from to create the internal file name strings. Based on the
|
|
unzip60-alt-iconv-utf8.patch suggested in a forum thread. This patch is
|
|
rather simple, just providing the new options to manually set the input
|
|
character set (generally OEM if archive from Windows and ISO otherwise).
|
|
These options are currently only available on Unix. This is separate from
|
|
the Unicode implementation that allows direct conversion between character
|
|
sets and bypasses these new options if an entry has Unicode. These options
|
|
are only for converting names from older archives without stored UTF-8 to
|
|
names that are readable on a Unix platform. This implementation includes
|
|
a short table to automatically guess the code page for a few common
|
|
locales. More locales can be added later, and a more complete solution
|
|
might be implemented later based on something like the libnatspec or
|
|
librcc libraries. However, the goal is for everyone to move to zippers
|
|
that support UTF-8 so these options are no longer needed. Enabled by
|
|
setting the USE_ICONV_MAPPING macro. Uses the iconv library which must be
|
|
available. (unzip.c, zipinfo.c, unix/unix.c, unix/unxcfg.h) [EG]

- Change fnfilter() from using code used for Unicode for wide char conversions
|
|
to using standard ANSI wide calls, avoiding dependencies on zwstring and so
|
|
the need to restructure that code so it works in all contexts. (extract.c)
|
|
[EG]
|
|
|
|
6.10a06 (9 Aug 2010):

|
|
defined. (process.c, unzip.c, unzip.h, unzpriv.h, zipinfo.c, vms/vms.c)
|

When this bit is set, a verification checksum is in the first 3 bytes of

the external attributes. In this case, only use last byte of external
|
|
attributes by clearing other bytes in G.crec.external_file_attributes.
|
|
(process.c) [EG]
