+ caret escapes, causing many non-wildcard names to be considered
+ wildcard names. Also, since VMS V7.2 on non-VAX, "?" is a

+ such. (Correcting this problem makes possible the first of the

---------------------------------------------
- To enable support for AES encryption, a separate IZ_AES_WG source kit
-is needed. On the Info-ZIP FTP server, the IZ_AES_WG source kit should
-be found in:

+in Info-ZIP programs can normally be found in the file

+ For export control reasons, it may be possible to find an UnZip
+ source kit from which these files have been removed. If the files
+ in the "aes_wg" subdirectory are missing, then the simplest
+ solution is to fetch a complete source kit from any of the usual
+ places. For more information if the aes_wg/README_AES_WG.txt
+ file is missing, it should also be available at:
-The latest kit should be:
-
- ftp://ftp.info-zip.org/pub/infozip/crypt/iz_aes_wg.zip
-
-but other, older kits may also be available there. Version
-compatibility information should be included in the IZ_AES_WG
-documentation. The latest version of that should be:
-
- ftp://ftp.info-zip.org/pub/infozip/crypt/README_AES_WG.txt
-
-It might be wise to read that before downloading any particular
-IZ_AES_WG kit.
-
- The IZ_AES_WG kit should be unpacked in the main UnZip directory,
-where it should populate the "aes_wg" subdirectory. For example, if
-the proper IZ_AES_WG kit is "iz_aes_wg13.zip", then use commands like

-
- For creating Windows executables, the Microsoft Visual C++ compiler
- platforms from version 2.x up to 8.0 (Visual Studio .Net C++ 2005)
- should work. Recent build tests have been run on VC++ 6.0, 7.1 and

- with Visual C++ 2008 - [VC++ 9.0]) create executables that are marked
- to run on Windows 2000 and newer, only. Although these Visual C++
- environments may succeed in building Windows Info-ZIP executables,
- they cannot (and must not) be used to create binaries for public
- distribution, if support for older systems is intended.
-
- Alternative compilers for the Intel platforms are OpenWatcom C++,
- GNU C (Cygwin and MinGW32 have been tested, others, such as emx/rsxnt
- may also work), Borland C++, or lcc-win32. DEC C/C++ for NT/Alpha
- may or may not still work.
-
- For the Watcom compiler, use WMAKE and win32\makefile.wat.
-
- For the Microsoft compilers, use NMAKE and win32\Makefile.
-
- For Cygwin or MinGW, use unix/Makefile and the "generic" target.
- (An old win32\Makefile.gcc may still be included in the kit, but it
- lacks support for many features, and may be of little value.)
-
- With emx+gcc, a good choice is GNUMake 3.75 (or higher) from the
- djgpp V2 distribution used on win32\Makefile.emx.
-
- The unzip32.dll WinDLL executables can be built using the appropriate
- Makefile in the win32\ subdirectory, or by using the Microsoft Visual
- C++ project files supplied below the windll\ subdirectory. Besides
- the MSC compilers, gcc-mingw32, Watcom C and Borland C allow to build

+
+ Apology
+ -------
+
+ Too much time has passed between the releases of UnZip versions 6.10b
+and 6.1c. UnZip 6.1c lacks support for some new features in Zip 3.1d.
+We'll try to get the missing features into UnZip 6.1d, and to get the
+final UnZip 6.1 released in a more timely way.

+
+ Description
+ -----------
+
+ The Info-ZIP programs UnZip (version 6.1 and later) and Zip (version
+3.1 and later) include optional support for Advanced Encryption Standard
+(AES) encryption, a relatively strong encryption method. Traditional
+zip encryption, in contrast, is now considered relatively weak and easy
+to crack.
+
+ The Info-ZIP AES implementation is based on the WinZip AES
+specification, and uses AES encryption code supplied by Brian Gladman.
+We refer to it as IZ_AES_WG (Info-ZIP AES WinZip/Gladman) or simply
+AES_WG. The WinZip AES scheme is described in:
+
+ http://www.winzip.com/aes_info.htm
+
+ Briefly, the WinZip AES scheme uses compression method 99 to flag an
+AES-encrypted archive member. (In contrast, PKZIP AES encryption uses
+an incompatible scheme with different archive data structures. However,
+current versions of PKZIP may also be able to process WinZip AES
+encrypted archive entries.)
+
+ The IZ_AES_WG implementation supports 128-, 192-, and 256-bit keys.
+See the various discussions of WinZip AES encryption on the Internet for
+more on the security of the WinZip AES encryption implementation.
+
+ The IZ_AES_WG source kit is based on an AES source kit provided by
+Brian Gladman, which we obtained at:
+
+ http://gladman.plushost.co.uk/oldsite/cryptography_technology/
+ fileencrypt/files.zip
+
+with one header file ("brg_endian.h") from a newer kit:
+
+ http://gladman.plushost.co.uk/oldsite/AES/aes-src-11-01-11.zip
+
+(Non-Windows users should use "unzip -a" when unpacking those kits.)
+
+ That site is no longer active, so the only independent sources for
+those kits may be Internet archive providers. Dr. Gladman's current AES
+material may be found at:
+
+ http://www.gladman.me.uk/AES
+ https://github.com/BrianGladman/AES
+
+ We chose the code from the older Gladman code kits primarily to
+ensure compatibility with WinZip. We made some changes to it to improve
+its portability to different hardware and operating systems.
+
+ The portability-related changes to the original Gladman code include:
+
+ Use of <string.h> instead of <memory.h>.
+
+ Use of "brg_endian.h" for endian determination.
+
+ Changing "brg_endian.h" to work with GNU C on non-Linux systems,
+ and on SunOS 4.x systems.
+
+ #include <limits.h> instead of "limits.h" in aes.h.
+
+ Changing some "long" types to "int" or "sha1_32t" in hmac.c and
+ hmac.h to accommodate systems (like Mac OS X on Intel) where a
+ 64-bit "long" type caused bad results.
+
+ Comments in the code identify the changes. (Look for "Info-ZIP".)
+The IZ_AES_WG kit includes the original files from those kits, as well
+as files which we have modified. The original forms of modified files
+are preserved in an "orig" subdirectory, for reference.
+
+ The name "IZ_AES_WG" (Info-ZIP AES WinZip/Gladman) is used by
+Info-ZIP to identify our implementation of WinZip AES encryption of Zip
+archive members, using encryption code supplied by Dr. Gladman. WinZip
+is a registered trademark of WinZip International LLC. PKZIP is a
+registered trademark of PKWARE, Inc.
+
+ The source code files from Dr. Gladman are subject to the LICENSE
+TERMS at the top of each source file. The entire IZ_AES_WG kit is
+provided under the Info-ZIP license, a copy of which is included in the
+file LICENSE in the source kits. The latest version of the Info-ZIP
+license should be available at:
+
+ http://www.info-zip.org/license.html
+
+ NOTE: The IZ_AES_WG source kit is intended for use with the Info-ZIP
+ UnZip and Zip programs ONLY. Any other use is unsupported and
+ not recommended.

+
+ Building UnZip and Zip with AES_WG Encryption Support
+ -----------------------------------------------------
+
+ The IZ_AES_WG source kit is normally included in the basic UnZip and
+Zip source kits, and its files should be found in an "aes_wg"
+subdirectory.
+
+ The build instructions (INSTALL) in the UnZip and Zip source kits
+describe how to build UnZip and Zip with (or without) support for AES_WG
+encryption.
+
+ The UnZip and Zip README files have additional general information on
+AES encryption, and the UnZip and Zip manual pages provide the details
+on how to use AES encryption in these programs.
+
+ Be aware that some countries or jurisdictions may restrict who may
+download or use strong encryption source code and binaries. Prospective
+users are responsible for determining whether they are legally allowed
+to download or use this encryption software.

+
+ Acknowledgements
+ ----------------
+
+ We're grateful to Dr. Gladman for providing the AES encryption code.
+Any problems involving AES_WG encryption in Info-ZIP programs should be
+reported to the Info-ZIP team, not to Dr. Gladman. However, any questions
+on AES encryption or decryption algorithms, or regarding Gladman's code
+(except as we modified and use it) should be addressed to Dr. Gladman.
+
+ We're grateful to WinZip for making the WinZip AES specification
+available, and providing the detailed information needed to implement
+it.

+ Issue Date: 24/01/2003
+
+ This file contains the compilation options for AES (Rijndael) and code
+ that is common across encryption, key scheduling and table generation.
+
+ OPERATION
+
+ These source code files implement the AES algorithm Rijndael designed by
+ Joan Daemen and Vincent Rijmen. The version in aes.c is designed for
+ block and key sizes of 128, 192 and 256 bits (16, 24 and 32 bytes) while
+ that in aespp.c provides for block and keys sizes of 128, 160, 192, 224
+ and 256 bits (16, 20, 24, 28 and 32 bytes). This file is a common header
+ file for these two implementations and for aesref.c, which is a reference
+ implementation.
+
+ This version is designed for flexibility and speed using operations on
+ 32-bit words rather than operations on bytes. It provides aes_both fixed
+ and dynamic block and key lengths and can also run with either big or
+ little endian internal byte order (see aes.h). It inputs block and key
+ lengths in bytes with the legal values being 16, 24 and 32 for aes.c and
+ 16, 20, 24, 28 and 32 for aespp.c
+
+ THE CIPHER INTERFACE
+
+ aes_08t (an unsigned 8-bit type)
+ aes_32t (an unsigned 32-bit type)
+ aes_fret (a signed 16 bit type for function return values)
+ aes_good (value != 0, a good return)
+ aes_bad (value == 0, an error return)
+ struct aes_ctx (structure for the cipher encryption context)
+ struct aes_ctx (structure for the cipher decryption context)
+ aes_rval the function return type (aes_fret if not DLL)
+
+ C subroutine calls:
+
+ aes_rval aes_set_block_size(unsigned int blen, aes_ctx cx[1]);
+ aes_rval aes_set_encrypt_key(const unsigned char in_key[],
+ unsigned int klen, aes_ctx cx[1]);
+ aes_rval aes_encrypt_block(const unsigned char in_blk[],
+ unsigned char out_blk[], const aes_ctx cx[1]);
+
+ aes_rval aes_dec_len(unsigned int blen, aes_ctx cx[1]);
+ aes_rval aes_set_decrypt_key(const unsigned char in_key[],
+ unsigned int klen, aes_ctx cx[1]);
+ aes_rval aes_decrypt_block(const unsigned char in_blk[],
+ unsigned char out_blk[], const aes_ctx cx[1]);
+
+ IMPORTANT NOTE: If you are using this C interface and your compiler does
+ not set the memory used for objects to zero before use, you will need to
+ ensure that cx.n_blk is set to zero before using these subroutine calls.
+
+ C++ aes class subroutines:
+
+ class AESclass for encryption
+ class AESclass for decryption
+
+ aes_rval len(unsigned int blen = 16);
+ aes_rval key(const unsigned char in_key[], unsigned int klen);
+ aes_rval blk(const unsigned char in_blk[], unsigned char out_blk[]);
+
+ aes_rval len(unsigned int blen = 16);
+ aes_rval key(const unsigned char in_key[], unsigned int klen);
+ aes_rval blk(const unsigned char in_blk[], unsigned char out_blk[]);
+
+ The block length inputs to set_block and set_key are in numbers of
+ BYTES, not bits. The calls to subroutines must be made in the above
+ order but multiple calls can be made without repeating earlier calls
+ if their parameters have not changed. If the cipher block length is
+ variable but set_blk has not been called before cipher operations a
+ value of 16 is assumed (that is, the AES block size). In contrast to
+ earlier versions the block and key length parameters are now checked
+ for correctness and the encryption and decryption routines check to
+ ensure that an appropriate key has been set before they are called.
+
+ COMPILATION
+
+ The files used to provide AES (Rijndael) are
+
+ a. aes.h for the definitions needed for use in C.
+ b. aescpp.h for the definitions needed for use in C++.
+ c. aesopt.h for setting compilation options (also includes common
+ code).
+ d. aescrypt.c for encryption and decrytpion, or
+ e. aescrypt.asm for encryption and decryption using assembler code.
+ f. aeskey.c for key scheduling.
+ g. aestab.c for table loading or generation.
+
+ The assembler code uses the NASM assembler. The above files provice
+ block and key lengths of 16, 24 and 32 bytes (128, 192 and 256 bits).
+ If aescrypp.c and aeskeypp.c are used instead of aescrypt.c and
+ aeskey.c respectively, the block and key lengths can then be 16, 20,
+ 24, 28 or 32 bytes. However this code has not been optimised to the
+ same extent and is hence slower (esepcially for the AES block size
+ of 16 bytes).
+
+ To compile AES (Rijndael) for use in C code use aes.h and exclude
+ the AES_DLL define in aes.h
+
+ To compile AES (Rijndael) for use in in C++ code use aescpp.h and
+ exclude the AES_DLL define in aes.h
+
+ To compile AES (Rijndael) in C as a Dynamic Link Library DLL) use
+ aes.h, include the AES_DLL define and compile the DLL. If using
+ the test files to test the DLL, exclude aes.c from the test build
+ project and compile it with the same defines as used for the DLL
+ (ensure that the DLL path is correct)
+
+ CONFIGURATION OPTIONS (here and in aes.h)
+
+ a. define BLOCK_SIZE in aes.h to set the cipher block size (16, 24
+ or 32 for the standard code, or 16, 20, 24, 28 or 32 for the
+ extended code) or leave this undefined for dynamically variable
+ block size (this will result in much slower code).
+ b. set AES_DLL in aes.h if AES (Rijndael) is to be compiled as a DLL
+ c. You may need to set PLATFORM_BYTE_ORDER to define the byte order.
+ d. If you want the code to run in a specific internal byte order, then
+ INTERNAL_BYTE_ORDER must be set accordingly.
+ e. set other configuration options decribed below.

+
+ The fundamental data processing units in Rijndael are 8-bit bytes. The
+ input, output and key input are all enumerated arrays of bytes in which
+ bytes are numbered starting at zero and increasing to one less than the
+ number of bytes in the array in question. This enumeration is only used
+ for naming bytes and does not imply any adjacency or order relationship
+ from one byte to another. When these inputs and outputs are considered
+ as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
+ byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
+ In this implementation bits are numbered from 0 to 7 starting at the
+ numerically least significant end of each byte (bit n represents 2^n).
+
+ However, Rijndael can be implemented more efficiently using 32-bit
+ words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
+ into word[n]. While in principle these bytes can be assembled into words
+ in any positions, this implementation only supports the two formats in
+ which bytes in adjacent positions within words also have adjacent byte
+ numbers. This order is called big-endian if the lowest numbered bytes
+ in words have the highest numeric significance and little-endian if the
+ opposite applies.
+
+ This code can work in either order irrespective of the order used by the
+ machine on which it runs. Normally the internal byte order will be set
+ to the order of the processor on which the code is to be run but this
+ define can be used to reverse this in special situations

+ lead to memory access errors when such 32-bit word accesses are not

+ A simple file encryption application based on
+
+ a. RFC2898 for key derivation (using HMAC-SHA1)
+ b. AES in CTR mode for encryption
+ c. HMAC-SHA1 for authentication
+ d. A Random Data Pool based on Peter Gutmann's ideas
+
+The command line is:
+
+ encfile password infile
+
+ If the last file name extension is ".enc", the file is assumed to be an
+ encrypted file and an attempt is made to decrypt it with the given password,
+ writing the output to a file with the same name except for the ".enc" on the
+ end. Otherwise the file is encrypted with the given password and the output
+ is written to a file with the same name except that ".enc" is added on the
+ end.

+
+ This file contains the compilation options for AES (Rijndael) and code
+ that is common across encryption, key scheduling and table generation.
+
+ OPERATION
+
+ These source code files implement the AES algorithm Rijndael designed by
+ Joan Daemen and Vincent Rijmen. The version in aes.c is designed for
+ block and key sizes of 128, 192 and 256 bits (16, 24 and 32 bytes) while
+ that in aespp.c provides for block and keys sizes of 128, 160, 192, 224
+ and 256 bits (16, 20, 24, 28 and 32 bytes). This file is a common header
+ file for these two implementations and for aesref.c, which is a reference
+ implementation.
+
+ This version is designed for flexibility and speed using operations on
+ 32-bit words rather than operations on bytes. It provides aes_both fixed
+ and dynamic block and key lengths and can also run with either big or
+ little endian internal byte order (see aes.h). It inputs block and key
+ lengths in bytes with the legal values being 16, 24 and 32 for aes.c and
+ 16, 20, 24, 28 and 32 for aespp.c
+
+ THE CIPHER INTERFACE
+
+ aes_08t (an unsigned 8-bit type)
+ aes_32t (an unsigned 32-bit type)
+ aes_fret (a signed 16 bit type for function return values)
+ aes_good (value != 0, a good return)
+ aes_bad (value == 0, an error return)
+ struct aes_ctx (structure for the cipher encryption context)
+ struct aes_ctx (structure for the cipher decryption context)
+ aes_rval the function return type (aes_fret if not DLL)
+
+ C subroutine calls:
+
+ aes_rval aes_set_block_size(unsigned int blen, aes_ctx cx[1]);
+ aes_rval aes_set_encrypt_key(const unsigned char in_key[],
+ unsigned int klen, aes_ctx cx[1]);
+ aes_rval aes_encrypt_block(const unsigned char in_blk[],
+ unsigned char out_blk[], const aes_ctx cx[1]);
+
+ aes_rval aes_dec_len(unsigned int blen, aes_ctx cx[1]);
+ aes_rval aes_set_decrypt_key(const unsigned char in_key[],
+ unsigned int klen, aes_ctx cx[1]);
+ aes_rval aes_decrypt_block(const unsigned char in_blk[],
+ unsigned char out_blk[], const aes_ctx cx[1]);
+
+ IMPORTANT NOTE: If you are using this C interface and your compiler does
+ not set the memory used for objects to zero before use, you will need to
+ ensure that cx.n_blk is set to zero before using these subroutine calls.
+
+ C++ aes class subroutines:
+
+ class AESclass for encryption
+ class AESclass for decryption
+
+ aes_rval len(unsigned int blen = 16);
+ aes_rval key(const unsigned char in_key[], unsigned int klen);
+ aes_rval blk(const unsigned char in_blk[], unsigned char out_blk[]);
+
+ aes_rval len(unsigned int blen = 16);
+ aes_rval key(const unsigned char in_key[], unsigned int klen);
+ aes_rval blk(const unsigned char in_blk[], unsigned char out_blk[]);
+
+ The block length inputs to set_block and set_key are in numbers of
+ BYTES, not bits. The calls to subroutines must be made in the above
+ order but multiple calls can be made without repeating earlier calls
+ if their parameters have not changed. If the cipher block length is
+ variable but set_blk has not been called before cipher operations a
+ value of 16 is assumed (that is, the AES block size). In contrast to
+ earlier versions the block and key length parameters are now checked
+ for correctness and the encryption and decryption routines check to
+ ensure that an appropriate key has been set before they are called.
+
+ COMPILATION
+
+ The files used to provide AES (Rijndael) are
+
+ a. aes.h for the definitions needed for use in C.
+ b. aescpp.h for the definitions needed for use in C++.
+ c. aesopt.h for setting compilation options (also includes common
+ code).
+ d. aescrypt.c for encryption and decrytpion, or
+ e. aescrypt.asm for encryption and decryption using assembler code.
+ f. aeskey.c for key scheduling.
+ g. aestab.c for table loading or generation.
+
+ The assembler code uses the NASM assembler. The above files provice
+ block and key lengths of 16, 24 and 32 bytes (128, 192 and 256 bits).
+ If aescrypp.c and aeskeypp.c are used instead of aescrypt.c and
+ aeskey.c respectively, the block and key lengths can then be 16, 20,
+ 24, 28 or 32 bytes. However this code has not been optimised to the
+ same extent and is hence slower (esepcially for the AES block size
+ of 16 bytes).
+
+ To compile AES (Rijndael) for use in C code use aes.h and exclude
+ the AES_DLL define in aes.h
+
+ To compile AES (Rijndael) for use in in C++ code use aescpp.h and
+ exclude the AES_DLL define in aes.h
+
+ To compile AES (Rijndael) in C as a Dynamic Link Library DLL) use
+ aes.h, include the AES_DLL define and compile the DLL. If using
+ the test files to test the DLL, exclude aes.c from the test build
+ project and compile it with the same defines as used for the DLL
+ (ensure that the DLL path is correct)
+
+ CONFIGURATION OPTIONS (here and in aes.h)
+
+ a. define BLOCK_SIZE in aes.h to set the cipher block size (16, 24
+ or 32 for the standard code, or 16, 20, 24, 28 or 32 for the
+ extended code) or leave this undefined for dynamically variable
+ block size (this will result in much slower code).
+ b. set AES_DLL in aes.h if AES (Rijndael) is to be compiled as a DLL
+ c. You may need to set PLATFORM_BYTE_ORDER to define the byte order.
+ d. If you want the code to run in a specific internal byte order, then
+ INTERNAL_BYTE_ORDER must be set accordingly.
+ e. set other configuration options decribed below.

+/* 5. BYTE ORDER WITHIN 32 BIT WORDS
+
+ The fundamental data processing units in Rijndael are 8-bit bytes. The
+ input, output and key input are all enumerated arrays of bytes in which
+ bytes are numbered starting at zero and increasing to one less than the
+ number of bytes in the array in question. This enumeration is only used
+ for naming bytes and does not imply any adjacency or order relationship
+ from one byte to another. When these inputs and outputs are considered
+ as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
+ byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
+ In this implementation bits are numbered from 0 to 7 starting at the
+ numerically least significant end of each byte (bit n represents 2^n).
+
+ However, Rijndael can be implemented more efficiently using 32-bit
+ words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
+ into word[n]. While in principle these bytes can be assembled into words
+ in any positions, this implementation only supports the two formats in
+ which bytes in adjacent positions within words also have adjacent byte
+ numbers. This order is called big-endian if the lowest numbered bytes
+ in words have the highest numeric significance and little-endian if the
+ opposite applies.
+
+ This code can work in either order irrespective of the order used by the
+ machine on which it runs. Normally the internal byte order will be set
+ to the order of the processor on which the code is to be run but this
+ define can be used to reverse this in special situations

+ variables by addressing these arrays as if they are arrays of 32-bit
+ words. On some machines this will always be possible but there may
+ be a large performance penalty if the byte arrays are not aligned on
+ the normal word boundaries. On other machines this technique will
+ lead to memory access errors when such 32-bit word accesses are not
+ properly aligned. The option SAFE_IO avoids such problems but will
+ often be slower on those machines that support misaligned access
+ (especially so if care is taken to align the input and output byte
+ arrays on 32-bit word boundaries). If SAFE_IO is not defined it is
+ assumed that access to byte arrays as if they are arrays of 32-bit

+/* If there are no global variables, the AES tables are placed in
+ a structure and a pointer is added to the AES context. If this
+ facility is used, the calling program has to ensure that this
+ pointer is managed appropriately. In particular, the value of
+ the t_dec(in,it) item in the table structure must be set to zero
+ in order to ensure that the tables are initialised. In practice
+ the three code sequences in aeskey.c that control the calls to
+ gen_tabs() and the gen_tabs() routine itself will require some
+ changes for a specific implementation. If global variables are
+ available it will generally be preferable to use them with the
+ precomputed FIXED_TABLES option that uses static global tables.
+
+ The following defines can be used to control the way the tables
+ are defined, initialised and used in embedded environments that
+ require special features for these purposes
+
+ the 't_dec' construction is used to declare fixed table arrays
+ the 't_set' construction is used to set fixed table values
+ the 't_use' construction is used to access fixed table values
+
+ 256 byte tables:
+
+ t_xxx(s,box) => forward S box
+ t_xxx(i,box) => inverse S box

+ t_xxx(f,l) => forward last round
+ t_xxx(i,n) => inverse normal round
+ t_xxx(i,l) => inverse last round

+ t_xxx(i,m) => key schedule table
+

+
+UNZIP
+
+
+ UnZip lists, tests, or extracts files from a ZIP archive (an archive
+ format commonly used on many different 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. A companion program, Zip, creates ZIP archives.
+
+ Info-ZIP UnZip and Zip were intended to be compatible with archives
+ created by PKWARE's PKZIP and PKUNZIP programs (originally for
+ MS-DOS), but in many cases the program options or default behaviors
+ differ. Nowadays, many other programs are available which work with
+ ZIP archives.
+
+ This help file describes the Unix-style command-line edition of
+ UnZip. A VMS CLI edition is also available, with a separate help
+ file.
+
+ Format
+
+ unzip [ unzip_options ] [ file[.zip] ] [ member ... ]
+ unzip -Z [ zipinfo_options ] [ file[.zip] ] [ member ... ]
+
+ Note: Beginning with UnZip version 6.1, the old command-line parser
+ has been replaced by one like the one used in Zip. One significant
+ change is that option negation now uses a TRAILING hyphen ("-"), so,
+ for example, -B- negates the -B option. This change was made
+ because a double hyphen ("--") now introduces a long option.
+
+ To display the basic built-in help, use the command:
+ unzip -h
+
+ To display the extended built-in help, use the command:
+ unzip -hh
+
+ The built-in help may be more current than this help file,
+ especially between full product releases.
+
+ To list all available options for a particular UnZip program, use
+ the command:
+ unzip --show-options
+
+ This report will not include any options which are available only on
+ other system types, or options which must be enabled at build-time
+ but were not enabled in the particular UnZip program being used.
+
+
+UNZIP
+
+ Command_Parameters
+
+
+ file[.zip]
+
+ File path/name of a ZIP archive. A wildcard name may be used to
+ specify multiple ZIP archives to be processed in one command. On
+ VMS systems, any of the standard wildcards for a directory/file
+ specification may be used: "...", "*", or "%" (or, since VMS V7.2,
+ "?"). The default archive file specification is ".ZIP".
+
+ Note that a ".zip" or ".ZIP" file type on an archive is merely a
+ convention, not a requirement. For example, a self-extracting ZIP
+ archive named "fred" or "fred.exe" could be processed as if it were
+ an ordinary archive; just specify the actual file name with its
+ actual name ending (if any), whatever that may be.
+
+ member ...
+
+ An optional list of archive members to be processed, separated by
+ spaces. If no member list is specified, then all archive members
+ are processed. Unix-like ("globbing") wildcard patterns may be used
+ to match multiple members:
+
+ * Matches a sequence of 0 or more characters.
+ ? Matches exactly 1 character.
+ [...] Matches any single character found inside the brackets.
+ Ranges are specified by a beginning character, a hyphen, and
+ an ending character. If an exclamation point ("!") or a
+ caret ("^") follows the left bracket, then the range of
+ characters within the brackets is complemented. That is,
+ anything except the characters inside the brackets is
+ considered a match. To specify a literal left bracket, use
+ the three-character sequence "[[]".
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ Options in this group specify the primary mode of operation of
+ UnZip. Only one of these primary mode options may be specified.
+
+ Note that uppercase options (like -T) must be specified in quotes
+ (unless SET PROCESS/PARSE_STYLE=EXTENDED is set). For example:
+
+ unzip "-VX" -a zipfile
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ -c
+
+ -c
+ --to-stdout
+
+ Primary Mode. Extract files to stdout/screen. This option is
+ similar to the -p option except that the name of each file is
+ displayed as it is extracted, and the -a option is allowed, which
+ can provide automatic ASCII-EBCDIC conversion, where appropriate.
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ -f
+
+ -f
+ --freshen
+
+ Primary Mode. Freshen existing files. That is, extract only those
+ files that already exist on disk and that are newer than the disk
+ copies. By default UnZip queries before overwriting, but the -o
+ option may be used to suppress the queries.
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ -h
+
+ -h
+ --help
+
+ Primary Mode. Display brief (roughly 24 lines) usage instructions.
+ See also -hh.
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ -hh
+
+ -hh
+ --long-help
+
+ Primary Mode. Display extended help (more complete usage
+ instructions). See also -h.
+
+
+UNZIP
+
+ Options_Primary_Mode
+
+ -l
+
+ -l
+ --list
+
+ Primary Mode. List archive members. By default, a brief format is
+ used, which includes the following items: member name, uncompressed
+ file size ("Length"), and modification date-time of the member. A
+ summary is included at the end of the report, showing total size and
+ count for all the members in the report. Specifying a member list
+ limits the report to those members.
+
+ Adding -v (--verbose) to an "unzip -l" command line adds the
+ following items to the report: compression method, compressed size
+ ("Size"), compression ratio, and 32-bit CRC.
+
+ In contrast to some other programs, UnZip does not include the
+ 12-byte encryption header in the compressed size values for a
+ Traditionally encrypted member. Therefore, compressed size and
+ compression ratio figures are independent of the member's encryption
+ status and show the correct compression performance. (The complete
+ size of the encrypted compressed data stream for archive members is

+ are never created. In this case, all backup files are named as the
+ original file with an appended tilde, and existing backup files are
+ deleted without notice. This feature works similarly to the default

+
+ Example: the old copy of "foo" is renamed to "foo~".

+ deleted before UnZip attempts to rename "foo" to "foo~". When this
+ rename attempt fails (because of a file lock, insufficient

+ cancelled, but the old backup file is already lost. A similar
+ scenario takes place when the sequence number range for numbered

+
+ [Non-VMS] Note that before UnZip version 6.1, on a non-VMS system, a

+ [WILD_STOP_AT_DIR] (Valid when the program was built with the C

+ "?" (single-character wildcard) and "*" (multi-character wildcard)
+ match any character in a member path/name. "-W" modifies the
+ pattern-matching behavior for archive members so that both "?"
+ (single-character wildcard) and "*" (multi-character wildcard) do
+ not match the directory separator character "/". (The two-character
+ sequence "**" acts as a multi-character wildcard that includes the
+ directory separator in its matched characters.) For example, with
+ "-W":
+
+ "*.c" matches "foo.c" but not "mydir/foo.c"
+ "**.c" matches both "foo.c" and "mydir/foo.c"
+ "*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"
+ "??*/*" matches "ab/foo" and "abc/foo"
+ but not "a/foo" or "a/b/foo"
+
+ This modified behavior is equivalent to the pattern matching style
+ used by the shells of some of UnZip's supported target OSs (one
+ example is Acorn RISC OS). This option may not be available on
+ systems where the Zip archive's internal directory separator
+ character "/" is allowed as regular character in native operating
+ system filenames.
+
+ [non-VMS] Currently, UnZip uses the same pattern matching rules for

+
+ An optional list of archive members to be excluded from processing.
+ Because wildcard characters normally match "/" directory separators
+ (for exceptions see the option -W), this option may be used to
+ exclude any files that are in subdirectories. For example, "unzip

+
+ When the program sees -x (--exclude) on a command line, it stops

+ options, it's simplest to specify -x (--exclude) and its member list
+ as the last items on a command line. Alternatively, the special

+
+ [all but Acorn, VM/CMS, MVS, Tandem] Allows UnZip to extract archive

+ directory (and its subdirectories).
+
+ For security reasons, UnZip normally removes "parent directory" path
+ components ("../") from the path names of archive members as they
+ are extracted. This safety feature (new for version 5.50) prevents
+ UnZip from accidentally writing files to directories outside the
+ current destination directory tree. The -: option sets UnZip back
+ to its previous, more liberal behavior, allowing exact extraction of
+ archives that use "../" path components to create multiple directory
+ trees at or above the level of the destination directory.
+
+ This option does not enable writing explicitly to the root directory
+ ("/"). To achieve this, it is necessary to set the extraction
+ target folder to "/" (by using an option like "-d /"). However,
+ when the -: option is specified, it is still possible implicitly to
+ write to the root directory if member paths specifying enough "../"
+ path components.
+

+ --control-in-name
+
+ [Unix] Allow control characters in file names of extracted ZIP
+ archive members. On Unix, a file name may contain any (8-bit)
+ character code with the two exceptions of "/" (the directory
+ delimiter) and NUL (0x00, the C string-termination character),
+ unless the specific file system has more restrictive conventions.
+ Generally, this allows embedding ASCII control characters or escape
+ sequences in file names. However, this feature allows the use of
+ malicious file names which can cause various kinds of bad trouble
+ when displayed on a user's terminal/emulator. (Even a file name
+ with unprintable but otherwise harmless characters can cause
+ problems for users.)
+
+ For these reasons, by default, UnZip applies a filter that removes
+ potentially dangerous control characters from the extracted file
+ names. The -^ option overrides this filter in the rare case that
+ embedded filename dangerous control characters are to be
+ intentionally restored.
+
+
+UNZIP
+
+ Environment_Options
+
+ UnZip's default behavior may be modified by placing command-line
+ options in an environment variable. This can be done with any
+ option, but it is probably most useful options like -a (auto-convert
+ text files), -L (downcase file names from systems with all uppercase
+ file names), -C (use case-insensitive name matching), -q (quiet), -o
+ (always overwrite), or -n (never overwrite).
+
+ For UnZip, the environment variable name on VMS is UNZIP_OPTS
+ (non-VMS: UNZIP). The name on VMS is different to avoid conflict
+ with a foreign-command DCL symbol, UNZIP. For compatibility with
+ Zip, if UNZIP_OPTS is not defined, then UnZip will use UNZIPOPT the
+ same way.
+
+ For ZipInfo ("unzip -Z"), the environment variable name on VMS is
+ ZIPINFO_OPTS (non-VMS: ZIPINFO). For compatibility with Zip, if
+ ZIPINFO_OPTS is not defined, then ZipInfo will use ZIPINFOOPT the
+ same way.
+
+ For example, to make UnZip act as quietly as possible, only
+ reporting errors, one could use commands like the following:
+
+ Unix Bourne (or similar) shell:
+ UNZIP='-q -q'; export UNZIP
+
+ Unix C shell:
+ setenv UNZIP '-q -q'
+
+ OS/2 or MS-DOS:
+ set UNZIP="-q -q"
+
+ VMS (with quotation to preserve lower case in DCL):
+ define UNZIP_OPTS "-q -q" ! Logical name, or
+ UNZIP_OPTS = "-q -q" ! DCL symbol. (Either works.)
+
+ Environment options are treated the same as any other command-line
+ options, except that they are effectively the first options on the
+ command line. To override an environment option, one may use an
+ explicit option to cancel or override it. For example, to override
+ one of the "quiet" flags in the example above, use a command like:
+
+ unzip -q- [other options] archive.zip
+
+ The leading hyphen is the normal option character, and the trailing
+ one negates the option, canceling one level of quietness. To cancel
+ multiple "quiet" flags, use multiple -q- options:
+
+ unzip -t -q- -q- archive
+ unzip -q- -q- -t archive
+
+ Note that multiple one-character options like "-q" and "-q" can be
+ combined into a single "-qq", but it's generally clearer to keep
+ each instance of each option separate. Similarly, negated
+ one-character options can be combined, as with "-q-q-", but "-q-
+ -q-" is generally clearer.
+
+ The examples show short (one-character) options, but long ("--")
+ options are also allowed.

+UNZIP
+
+ Encryption_Decryption
+
+ Zip and UnZip have long supported a relatively weak encryption
+ method, which we call Traditional ZIP encryption. The source code
+ for Traditional encryption is included in the source kits, and
+ support for Traditional encryption is enabled by default.
+ (Build-time C macro: CRYPT_TRAD.)
+
+ Beginning with UnZip version 6.1 and Zip version 3.1, these programs
+ also offer a stronger, Advanced Encryption Standard (AES) encryption
+ method, which we call AES WinZip/Gladman (AES_WG) encryption. (The
+ encryption code was supplied by Brian Gladman, and the archive
+ format is intended to be compatible with that used by the WinZip
+ program. WinZip is a registered trademark of WinZip International
+ LLC.) The source code for AES_WG encryption is distributed in a
+ separate kit (for export control reasons), and support for AES_WG
+ encryption must be enabled explicitly at build time. (Build-time C
+ macro: CRYPT_AES_WG.) See the INSTALL file in the source kit for
+ details on how to enable AES_WG encryption (or how to disable
+ Traditional encryption).
+
+ For details on the WinZip AES scheme, see:
+ http://www.winzip.com/aes_info.htm
+
+ For information on the separate AES_WG source kit, see:
+ ftp://ftp.info-zip.org/pub/infozip/crypt/
+ ftp://ftp.info-zip.org/pub/infozip/crypt/README_AES_WG.txt
+
+ Normally, encryption passwords are supplied by the user
+ interactively when requested by the program. See the -P option for
+ a (less secure) method of specifying a password on the command line.
+
+ With Traditional encryption, when decrypting, a password will be
+ checked against header data, and used if it appears to be correct.
+ The correct password will always check out against the header data,
+ but there is a 1-in-256 chance that an incorrect password will as
+ well. (This is a security feature of the PKWARE archive format; it
+ helps prevent brute-force attacks that might otherwise gain a large
+ speed advantage by testing only the header.) In the case that an
+ incorrect password is given but it passes the header test anyway,
+ either an incorrect CRC will be generated for the extracted data or
+ else UnZip will fail during the extraction because the "decrypted"
+ bytes do not constitute a valid compressed data stream.
+
+ If the first password fails the header check on some file, UnZip
+ will prompt for another password, and so on until all files are
+ extracted. If a password is not known, entering a null password
+ (that is, just a carriage return or "Enter") is taken as a signal to
+ skip all further prompting. Only unencrypted files in the
+ archive(s) will thereafter be extracted. (The situation is actually
+ a little more complicated. Some old versions of Zip and ZipCloak
+ allowed null passwords, so UnZip checks each encrypted file to see
+ if the null password works. This may result in "false positives"
+ and extraction errors, as noted above.)
+
+ Archives encrypted with 8-bit-character passwords (for example,
+ passwords with accented European characters) may not be portable
+ across systems or to other archivers. This problem stems from the
+ use of multiple encoding methods for such characters, including
+ Latin-1 (ISO 8859-1) and OEM code page 850. DOS PKZIP 2.04g uses
+ the OEM code page; Windows PKZIP 2.50 uses Latin-1 (and is therefore
+ incompatible with DOS PKZIP; Info-ZIP uses the OEM code page on DOS,
+ OS/2 and Win3.x ports but ISO coding (Latin-1 etc.) everywhere else;
+ and Nico Mak's WinZip 6.x does not allow 8-bit-character passwords
+ at all. UnZip 5.3 (or newer) attempts to use the default character
+ set first (e.g., Latin-1), followed by the alternate one (e.g., OEM
+ code page) to test passwords. On EBCDIC systems, if both of these
+ fail, EBCDIC encoding will be tested as a last resort. (EBCDIC is
+ not tested on non-EBCDIC systems, because there are no known
+ archivers that encrypt using EBCDIC encoding.) ISO character
+ encodings other than Latin-1 are not supported. The new addition of
+ (partial) Unicode (UTF-8) support in UnZip 6.0 has not yet been
+ adapted to the encryption password handling in UnZip. On systems
+ that use UTF-8 as native character encoding, UnZip simply tries
+ decryption with the native UTF-8 encoded password; the built-in
+ attempts to check the password in translated encoding have not yet
+ been adapted for UTF-8 support and will consequently fail.

+ Examples
+
+ To use UnZip to extract all members of the archive letters.zip into
+ the current directory and subdirectories below it, creating any
+ subdirectories as necessary:
+
+ unzip letters
+
+ To extract all members of letters.zip into the current directory
+ only:
+
+ unzip -j letters
+
+ To test letters.zip, printing only a summary message indicating
+ whether the archive is OK or not:
+
+ unzip -t -q letters
+
+ To test all ".zip" archives in the current directory, printing only
+ the summaries:
+
+ unzip -t -q *.zip
+
+ (On a Unix system, the wildcard archive name would typically need to
+ be quoted to keep a a Unix shell from expanding ("globbing") it.
+ This is not necessary on VMS.)
+
+ The following command extracts to standard output all members of
+ letters.zip whose names end in ".tex", auto-converting to the local
+ end-of-line convention, in Stream_LF record format, and piping the
+ output into TYPE /PAGE:
+
+ pipe unzip -c -a -S letters *.tex | type /page sys$input
+
+ To extract from source.zip all Fortran and C source files (*.f, *.c,
+ *.h) and Makefile into the SYS$SCRATCH directory:
+
+ unzip source.zip *.[fch] Makefile -d sys$scratch
+
+ To extract all FORTRAN and C source files, regardless of case (for
+ example, both *.c and *.C, and any makefile, Makefile, MAKEFILE or
+ similar):
+
+ unzip -C source.zip *.[fch] makefile -d sys$scratch
+
+ The following command extracts only newer versions of the files
+ already in the current directory, without querying. (Note: Be
+ careful of extracting in one timezone an archive created in another.
+ ZIP archives created by Zip versions before 2.1 contain no timezone
+ information, and a "newer" file from an eastern timezone may, in
+ fact, be older):
+
+ unzip -f -o sources
+
+ To extract newer versions of the files already in the current
+ directory and to create any files not already there (same caveat as
+ previous example):
+
+ unzip -u -o sources
+
+ To display a configuration report showing the program version, the
+ OS and compiler used to build it, a list of optional features
+ enabled at build time, and the values of all the relevant
+ environment variables:
+
+ unzip -v
+
+ In the last five examples, assume that UNZIP_OPTS is set to -q. To
+ do a (singly) quiet listing:
+
+ unzip -l file.zip
+
+ To do a doubly quiet listing:
+
+ unzip -l -q file.zip
+
+ (Note that the ".zip" is generally not necessary.) To do a standard
+ listing:
+
+ unzip -l -q- file.zip
+
+ or:
+
+ unzip -lq- file.zip
+
+ or:
+
+ unzip -q-l file.zip

+
+ Exit_Status
+
+ UnZip's exit status approximates the exit codes defined by PKWARE.
+ On VMS, UnZip's UNIX-style exit values are translated into VMS-style
+ status codes with facility code 1954 = %x7A2, and with the
+ inhibit-message (%x10000000) and facility-specific (%x00008000) bits
+ set:
+
+ %x17A28001 normal exit
+ %x17A28000 + 16*UnZip_error_code warnings
+ %x17A28002 + 16*UnZip_error_code normal errors
+ %x17A28004 + 16*UnZip_error_code fatal errors
+
+ Note that multiplying the UNIX-style UnZip error code by 16 places
+ it conveniently in the hexadecimal representation of the VMS exit
+ code, "__" in %x17A28__s, where "s" is the severity code. For
+ example, a missing archive might cause UnZip error code 9, which
+ would be transformed into the VMS exit status %X17A28092.
+
+ The UnZip VMS exit codes include severity values which approximate
+ those defined by PKWARE, as shown in the following table:

+UNZIP
+
+ Bugs
+
+ Multi-part archives are not yet supported, except in conjunction
+ with Zip. (All parts must be concatenated together in order, and
+ then "zip -F" (for Zip 2.x) or "zip -FF" (for Zip 3.x) must be
+ performed on the concatenated archive in order to "fix" it. Also,
+ zip 3.0 and later can combine multi-part (split) archives into a
+ combined single-file archive using "zip -s- inarchive -O
+ outarchive". See the zip manual page for more information.) This
+ may be corrected in the next major release.
+
+ Archives read from standard input are not yet supported, except with
+ UnZip (and then only the first member of the archive can be
+ extracted).
+
+ Archives encrypted with 8-bit-character passwords (such as passwords
+ with accented European characters) may not be portable across
+ systems and/or other archivers. See also Encryption_Decryption.
+
+ UnZip's -M ("--more") option tries to take into account automatic
+ wrapping of long lines. However, the code may fail to detect the
+ correct wrapping locations. First, TAB characters (and similar
+ control sequences) are not taken into account, they are handled as
+ ordinary printable characters. Second, depending on the actual
+ system type, UnZip may not detect the true terminal/emulator
+ geometry, but instead may rely on "commonly used" default
+ dimensions. The correct handling of tabs would require the
+ implementation of a query for the actual tab setup on the output
+ terminal/emulator.
+
+ [Unix] Unix special files such as FIFO buffers (named pipes), block
+ devices and character devices are not restored even if they are
+ somehow represented in the archive, nor are hard-linked files
+ relinked. Basically, the only file types restored by UnZip are
+ regular files, directories, and symbolic (soft) links.
+
+ [OS/2] Extended attributes for existing directories are only updated
+ if the -o ("--overwrite") option is given. This is a limitation of
+ the operating system; because directories only have a creation time
+ associated with them, UnZip has no way to determine whether the
+ stored attributes are newer or older than those on disk. In
+ practice this may mean a two-pass approach is required: first
+ unpack the archive normally (with or without freshening/updating
+ existing files), then overwrite just the directory entries (for
+ example, "unzip -o foo */").
+
+ Note that uppercase options (-C, -D, -L, -M, -P, -S, -T, -V, -X, -Y,
+ and -Z) must be specified in quotes (unless SET PROC/PARSE=EXTEND is
+ set). For example:
+
+ unzip "-VX" -a zipfile
+
+ When extracting to SYS$OUTPUT (-c or -p options) redirected to a
+ file, you may want to override the default text file conversion by
+ specifying the -b option. A single "-b" option switches to "binary
+ piping" mode for Zip entries marked as non-text, only. To force
+ "binary piping" mode even for Zip file entries marked as text, the
+ "-bb" option should be used. (Please note that a later "-a" cancels
+ any -b option, see below.)
+
+ The output conversion options -b and -a may be combined to perform
+ binary conversions on binary files and text conversion on text
+ files. But note: For compatibility with implementation on other
+ systems, -b cancels any -a option; to get the intended result, -a
+ must be specified AFTER -b. And, in combination, "text" recognition
+ takes precedence; this means that -bba (-bb -a) has the same effect
+ as -ba (-b -a), and -aa overrides binary conversion for ALL files.
+
+ The conversion option -S is only effective when used together with
+ -a or -aa. When specified, "text" files are written in Stream_LF
+ record format instead of the VMS default of Variable-Length record
+ format. (When no conversion options are specified, all non-VMS
+ entries are always written as Stream_LF files.)
+
+ Please note that using the "-P<password>" option is higly insecure,
+ the plaintext password may be seen by others. For this reason (and
+ because of lack of space), the "-P<password>" option is not
+ advertised on UnZip's online help screen.

+
+ File path/name of a ZIP archive. A wildcard name may be used to
+ specify multiple ZIP archives to be processed in one command. On
+ VMS systems, any of the standard wildcards for a directory/file
+ specification may be used: "...", "*", or "%" (or, since VMS V7.2,
+ "?"). The default archive file specification is "[]*.ZIP".
+
+ Note that a ".zip" or ".ZIP" file type on an archive is merely a
+ convention, not a requirement. For example, a self-extracting ZIP
+ archive named "fred" or "fred.exe" could be processed as if it were
+ an ordinary archive; just specify the actual file name with its

+
+ member ...
+
+ An optional list of archive members to be processed, separated by

+
+ * Matches a sequence of 0 or more characters.
+ ? Matches exactly 1 character.
+ [...] Matches any single character found inside the brackets.
+ Ranges are specified by a beginning character, a hyphen, and
+ an ending character. If an exclamation point ("!") or a
+ caret ("^") follows the left bracket, then the range of
+ characters within the brackets is complemented. That is,

+ considered a match. To specify a literal left bracket, use
+ the three-character sequence "[[]".

+ pattern-matching behavior for archive members so that both "?"
+ (single-character wildcard) and "*" (multi-character wildcard) do
+ not match the directory separator character "/". (The two-character
+ sequence "**" acts as a multi-character wildcard that includes the
+ directory separator in its matched characters.) For example, with
+ "-W":
+
+ "*.c" matches "foo.c" but not "mydir/foo.c"
+ "**.c" matches both "foo.c" and "mydir/foo.c"
+ "*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"

+ but not "a/foo" or "a/b/foo"
+
+ This modified behavior is equivalent to the pattern matching style
+ used by the shells of some of UnZip's supported target OSs (one
+ example is Acorn RISC OS). This option may not be available on
+ systems where the Zip archive's internal directory separator
+ character "/" is allowed as regular character in native operating

+
+ When the program sees -x (--exclude) on a command line, it stops

+ options, it's simplest to specify -x (--exclude) and its member list
+ as the last items on a command line. Alternatively, the special
+ name "@" can be used to terminate the member list (and cause the

+
+ Detailed_Description
+
+ ZipInfo has three basic report formats, providing different degrees
+ of detail in the information about the members of an archive: a
+ simple list of names (-1, -2), a Unix ls-style listing (-l, -m, -s),
+ and a very detailed analysis (-v). Some of the information, such as
+ file sizes, is easy to interpret. Some of the information involves
+ fairly obscure details of ZIP archive structure. ZIP archive
+ structure is documented in the PKWARE Inc. APPNOTE.TXT:
+ http://www.pkware.com/documents/casestudies/APPNOTE.TXT
+
+ The table below shows some typical -l report entries:
+

+ RWED,RE, 3.1 vms 6656 bx 2295 defN 07-Aug-15 14:12 it/T.EXE;8
+
+ Field 1 (Perm/Prot) shows the file permission/protection attributes,
+ formatted according to the original operating system or file system
+ where the archive was created.
+
+ Field 2 (Zver) shows the (approximate) version of the Zip program
+ which created the archive.
+
+ Field 3 (Ofs) shows the original operating system where the archive
+ was created, or the file system on which the member file was stored.
+
+ Field 4 (UncSize) shows the original, uncompressed file size.
+
+ Field 5 (At) shows some archive member attributes, as detailed in
+ the tables below. The first character indicates whether a file was
+ binary or text, and whether it was encrypted. The second character
+ indicates the presence of a data descriptor and/or an extra field in
+ the member data.
+
+ | File Type Extra Field |
+ First char | binary text yes no | Second char
+ --------------+-------+----- ------+-----+--------------------
+ Encrypted no | b t x - | no Data Descriptor
+ yes | B T X l | yes
+
+ A Data Descriptor holds CRC and size data at an alternate place in
+ the archive (after processed member data instead of before), and is
+ normally used when the archiving program can't seek in the output
+ archive data/file. An Extra Field can hold a wide variety of data,
+ including 64-bit file sizes, many kinds of OS-specific attribute
+ data, UTC times, and so on.
+
+ Field 6 (CmpSize) shows the compressed file size. With -m, this
+ field shows the compression fraction as a percentage. With -s (the
+ default), this field is omitted. This compressed size value (unlike
+ the one in an "unzip -l" report) includes all the overhead resulting
+ from Traditional encryption.
+
+ Field 7 (Cmth) shows the compression method used. Note that AES_WG
+ encryption is treated as a compression method here. Not all of the
+ methods shown in the table below are supported. (Some are
+ obsolete.)

+
+UNZIP
+
+ ZipInfo_mode
+
+ Environment_Options
+
+ ZipInfo's default behavior may be modified by placing command-line
+ options in an environment variable. This can be done with any
+ option, but it is probably most useful options like -T (decimal time
+ format) or one of the non-default Unix format options: -l, -m.
+
+ For ZipInfo ("unzip -Z"), the environment variable name on VMS is
+ ZIPINFO_OPTS (non-VMS: ZIPINFO). For compatibility with Zip, if
+ ZIPINFO_OPTS is not defined, then ZipInfo will use ZIPINFOOPT the
+ same way.
+
+ For example, to make the default format the long Unix format instead
+ of the short Unix format, one could use commands like the following:
+
+ Unix Bourne (or similar) shell:
+ ZIPINFO='-l'; export UNZIP
+
+ Unix C shell:
+ setenv ZIPINFO '-l'
+
+ OS/2 or MS-DOS:
+ set ZIPINFO="-l"
+
+ VMS (with quotation to preserve lower case in DCL):
+ define ZIPINFO_OPTS "-l" ! Logical name, or
+ ZIPINFO_OPTS = "-l" ! DCL symbol. (Either works.)
+
+ Environment options are treated the same as any other command-line
+ options, except that they are effectively the first options on the
+ command line. To override an environment option, one may use an
+ explicit option to cancel or override it. For example, to disable
+ the totals trailer line by default, one could use commands like the
+ following:
+
+ Unix Bourne (or similar) shell:
+ ZIPINFO='-t-'; export ZIPINFO
+
+ Unix C shell:
+ setenv ZIPINFO '-t-'
+
+ VMS (with quotation to preserve lower case in DCL):
+ define ZIPINFO_OPTS "-t-" ! Logical name, or
+ ZIPINFO_OPTS = "-t-" ! DCL symbol. (Either works.)
+
+ The examples show short (one-character) options, but long ("--")
+ options are also allowed.
+
+
+UNZIP
+
+ ZipInfo_mode
+
+ Examples
+
+ To get a basic, short-format listing of the complete contents of a
+ ZIP archive zip31c.zip, with both header and totals lines, use only
+ the archive name as an argument to zipinfo:
+
+ zipinfo zip31c.zip
+ zipinfo zip31c
+
+ To produce a basic, long-format listing (not verbose), including
+ header and totals lines, use -l:
+
+ zipinfo -l zip31c.zip
+
+ To list the complete contents of the archive without header and
+ totals lines, either negate the -h and -t options or else specify
+ the contents explicitly:
+
+ zipinfo -h- -t- zip31c.zip
+ zipinfo zip31c.zip *
+
+ (On a Unix system, the wildcard member name would typically need to
+ be quoted to keep a a Unix shell from expanding ("globbing") it.
+ This is not necessary on VMS.)
+
+ To list information on a single archive member, in medium format,
+ specify the member name explicitly:
+
+ zipinfo -m unzip60.zip */unshrink.c
+
+ When any member name is specified, the header and totals trailer
+ are, by default, not included in the report, but explicitly
+ specifying -h and/or -t will restore them. For example:
+
+ zipinfo -m -t unzip610b.zip *.[ch] */Make*
+
+ On a Unix system, one could use the -T option along with an external
+ sorting program (and another filter like "head" or "tail") to get a
+ listing of the least or most recently modified files in the archive:
+
+ zipinfo -l -T -h- -t- zip31c.zip | sort -k 8 | head -12
+ zipinfo -l -T -h- -t- zip31c.zip | sort -r -k 8 | head -12
+
+ The "sort" option "-k 8" tells it to sort on field 8, which is the
+ date-time field in a long- or medium-format (-l, -m) ZipInfo report.
+ (Use "-k 7" for the short (-s) format.) The -r option reverses the
+ default smallest-to-largest sort order.
+
+
+UNZIP
+
+ ZipInfo_mode
+
+ Bugs
+
+ As with UnZip, ZipInfo's -M ("--more") option is overly simplistic
+ in its handling of screen output. As noted above, it fails to
+ detect the wrapping of long lines and may thereby cause lines at the
+ top of the screen to be scrolled off before being read. ZipInfo
+ should detect and treat each occurrence of line-wrap as one
+ additional line printed. This requires knowledge of the screen's
+ width as well as its height. In addition, ZipInfo should detect the
+ true screen geometry on all systems.
+
+ The interactions among the various listing format, header, and
+ trailer options (-h, -l, -m, -s, -t) are unnecessarily complex and
+ should be simplified, despite the potential disruption to current
+ users.

+
+UNZIP
+
+ UnZip lists, tests, or extracts files from a ZIP archive (an
+ archive format commonly used on many different 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. A companion program, Zip, creates ZIP
+ archives.
+
+ Info-ZIP UnZip and Zip were intended to be compatible with archives
+ created by PKWARE's PKZIP and PKUNZIP programs (originally for
+ MS-DOS), but in many cases the program options or default behaviors
+ differ. Nowadays, many other programs are available which work
+ with ZIP archives.
+
+ This help file describes the VMS CLI edition of UnZip. A
+ Unix-style command-line edition is also available, with a separate
+ help file.
+
+ The VMS CLI edition of UnZip adds a command-line translator to the
+ normal UnZip program. This translator transforms a set of
+ VMS-style qualifiers and parameters into an equivalent set of
+ Unix-style options and parameters, and then passes those
+ transformed arguments to UnZip's standard Unix-style command-line
+ processor. The documentation often shows the related Unix-style
+ options in parentheses after a VMS-style qualifier. For example:
+ /HELP (-h, -hh).
+
+ Format:
+
+ UNZIP [/unzip_qualifiers] [file[.zip]] [member [,...]]
+
+ UNZIP /ZIPINFO [/zipinfo_qualifiers] [file[.zip]] [member [,...]]
+
+ ZIPINFO [/zipinfo_qualifiers] [file[.zip]] [member [,...]]
+
+ To display the basic built-in help, use the command:

+ To display the extended built-in help, use the command:
+
+ UNZIP /HELP=EXTENDED
+
+ The built-in help may be more current than this help file,
+ especially between full product releases.

+ The VMS CLI edition of the program can also provide built-in help
+ on the Unix-style command-line edition; just use the "-h" or "-hh"
+ options.

+
+ Command_Parameters
+
+ file[.zip]
+
+ File path/name of a ZIP archive. A wildcard name may be used to
+ specify multiple ZIP archives to be processed in one command.
+ On VMS systems, any of the standard wildcards for a
+ directory/file specification may be used: "...", "*", or "%"
+ (or, since VMS V7.2, "?"). The default archive file
+ specification is ".ZIP".
+
+ Note that a ".zip" or ".ZIP" file type on an archive is merely a
+ convention, not a requirement. For example, a self-extracting
+ ZIP archive named "fred" or "fred.exe" could be processed as if
+ it were an ordinary archive; just specify the actual file name
+ with its actual name ending (if any), whatever that may be.
+
+ member [,...]
+
+ An optional list of archive members to be processed, separated
+ by commas. If no member list is specified, then all archive
+ members are processed. Unix-like ("globbing") wildcard patterns
+ may be used to match multiple members:
+
+ * Matches a sequence of 0 or more characters.
+ ? Matches exactly 1 character.
+ [...] Matches any single character found inside the brackets.
+ Ranges are specified by a beginning character, a hyphen,
+ and an ending character. If an exclamation point ("!")
+ or a caret ("^") follows the left bracket, then the
+ range of characters within the brackets is complemented.
+ That is, anything except the characters inside the
+ brackets is considered a match. To specify a literal
+ left bracket, use the three-character sequence "[[]".

+ uncompressed file size ("Length"), and modification date-time of
+ the member. A summary is included at the end of the report,
+ showing total size and count for all the members in the report.
+ Specifying a member list limits the report to those members.
+
+ Adding /VERBOSE to an "UNZIP /LIST" command line adds the following
+ items to the report: compression method, compressed size ("Size"),
+ compression ratio, and 32-bit CRC.
+
+ In contrast to some other programs, UnZip does not include the
+ 12-byte encryption header in the compressed size values for a
+ Traditionally encrypted member. Therefore, compressed size and
+ compression ratio figures are independent of the member's
+ encryption status and show the correct compression performance.
+ (The complete size of the encrypted compressed data stream for
+ archive members is reported by the more verbose ZipInfo reports.
+ See ZipInfo.
+
+ If UnZip was built with OS2_EAS enabled, then the /LIST report also
+ includes the sizes of stored OS/2 extended attributes (EAs) and
+ OS/2 access control lists (ACLs). In addition, the archive comment
+ and individual member comments (if any) are displayed.
+
+ If a file was archived from a single-case file system (for example,
+ the old MS-DOS FAT file system) and the /NAMES=DOWNCASE option was
+ given, the filename is converted to lowercase and is shown prefixed
+ with a caret (^).

+ /AUTO_DIRECTORY (-da)
+
+ /NOAUTO_DIRECTORY (default)
+ /AUTO_DIRECTORY[=REUSE]
+
+ Specifies a destination directory for extracted files which is
+ derived from the base name of the archive. By default, files are
+ extracted (and subdirectories created) in the current default
+ directory. With /AUTO_DIRECTORY, UnZip automatically derives a
+ subdirectory name from the archive name, creates that subdirectory,
+ and extracts files into that subdirectory.
+
+ For example, with /AUTO_DIRECTORY, extraction of "fred.zip" is done
+ into subdirectory "[.fred]" instead of into the current directory.
+ (On non-VMS systems, subdirectory "fred".)
+
+ Using this option can help to avoid cluttering the current
+ directory with files extracted from an archive whose structure does
+ not include a top-level directory.

+
+ The optional keywords and values are:
+
+ CASE=BLIND Name matching is case-insensitive. (-C)
+ CASE=SENSITIVE Name matching is case-sensitive. (Default.)
+
+ By default, case-sensitive matching is done. For example,
+ specifying "makefile" on the command line will match only
+ "makefile" in the archive, not "Makefile" or "MAKEFILE". On many
+ systems, the local file system is case-insensitive, so
+ case-insensitive name matching would be more natural. With
+ /MATCH=CASE=BLIND, "makefile" would match "makefile", "Makefile",
+ or "MAKEFILE".
+
+ /MATCH does not affect the search for the ZIP archive file(s), nor
+ the matching of archive members to existing files on the extraction
+ path. So, on a case-sensitive file system, UnZip will never try to
+ overwrite a file "FOO" when extracting a member named "foo"!
+
+ [WILD_STOP_AT_DIR] If the C macro WILD_STOP_AT_DIR is defined at
+ build time, then an additional keyword is allowed:
+
+ NOWILD_MATCH_SLASH Wildcards stop at directory slash. (-W)
+ WILD_MATCH_SLASH Wildcards match directory slash. (Default.)
+
+ By default, the wildcard characters "?" (single-character wildcard)
+ and "*" (multi-character wildcard) match any character in a member
+ path/name. /MATCH=NOWILD_MATCH_SLASH (-W) modifies the
+ pattern-matching behavior for archive members so that both "?"
+ (single-character wildcard) and "*" (multi-character wildcard) do
+ not match the directory separator character "/". (The
+ two-character sequence "**" acts as a multi-character wildcard that
+ includes the directory separator in its matched characters.) For
+ example, with /MATCH=NOWILD_MATCH_SLASH:
+
+ "*.c" matches "foo.c" but not "mydir/foo.c"
+ "**.c" matches both "foo.c" and "mydir/foo.c"
+ "*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"
+ "??*/*" matches "ab/foo" and "abc/foo"
+ but not "a/foo" or "a/b/foo"
+
+ This modified behavior is equivalent to the pattern matching style
+ used by the shells of some of \fIUnZip\fP's supported target OSs
+ (one example is Acorn RISC OS). This option may not be available
+ on systems where the Zip archive's internal directory separator
+ character "/" is allowed as regular character in native operating
+ system filenames.
+
+ [non-VMS] (Currently, UnZip uses the same pattern matching rules
+ for both wildcard archive file name specifications and archive

+
+ Environment_Options
+
+ UnZip's default behavior may be modified by placing Unix-style

+ translator acts only on the command line itself, not on the
+ environment variables.) This can be done with any option, but it is
+ probably most useful options like -a (/TEXT, auto-convert text
+ files), -L (/NAMES, downcase file names from systems with all
+ uppercase file names), -C (/MATCH=CASE=BLIND, use case-insensitive
+ name matching), -q (/QUIET, quiet), -o (/EXISTING, always
+ overwrite), or -n (/EXISTING, never overwrite).
+
+ For UnZip, the environment variable name on VMS is UNZIP_OPTS
+ (non-VMS: UNZIP). The name on VMS is different to avoid conflict
+ with a foreign-command DCL symbol, UNZIP. For compatibility with
+ Zip, if UNZIP_OPTS is not defined, then UnZip will use UNZIPOPT the
+ same way.
+
+ For ZipInfo ("UNZIP /ZIPINFO"), the environment variable name on
+ VMS is ZIPINFO_OPTS (non-VMS: ZIPINFO). For compatibility with
+ Zip, if ZIPINFO_OPTS is not defined, then ZipInfo will use
+ ZIPINFOOPT the same way.
+ For example, to make UnZip act as quietly as possible, only
+ reporting errors, one could use commands like the following (with
+ quotation to preserve lower case in DCL):
+
+ define UNZIP_OPTS "-q -q" ! Logical name, or
+ UNZIP_OPTS = "-q -q" ! DCL symbol. (Either works.)
+
+ Environment options are treated the same as any other Unix-style
+ command-line options, except that they are effectively the first
+ options on the command line. Generally, the VMS CLI translator
+ will override an environment option if an explicit corresponding
+ VMS-style qualifier is specified.

+ Encryption_Decryption
+
+ Zip and UnZip have long supported a relatively weak encryption
+ method, which we call Traditional ZIP encryption. The source code
+ for Traditional encryption is included in the source kits, and
+ support for Traditional encryption is enabled by default.
+ (Build-time C macro: CRYPT_TRAD.)
+
+ Beginning with UnZip version 6.1 and Zip version 3.1, these
+ programs also offer a stronger, Advanced Encryption Standard (AES)
+ encryption method, which we call AES WinZip/Gladman (AES_WG)
+ encryption. (The encryption code was supplied by Brian Gladman,
+ and the archive format is intended to be compatible with that used
+ by the WinZip program. WinZip is a registered trademark of WinZip
+ International LLC.) The source code for AES_WG encryption is
+ distributed in a separate kit (for export control reasons), and
+ support for AES_WG encryption must be enabled explicitly at build
+ time. (Build-time C macro: CRYPT_AES_WG.) See the INSTALL file in
+ the source kit for details on how to enable AES_WG encryption (or
+ how to disable Traditional encryption).
+
+ For details on the WinZip AES scheme, see:
+ http://www.winzip.com/aes_info.htm
+
+ For information on the separate AES_WG source kit, see:
+ ftp://ftp.info-zip.org/pub/infozip/crypt/
+ ftp://ftp.info-zip.org/pub/infozip/crypt/README_AES_WG.txt
+
+ Normally, encryption passwords are supplied by the user
+ interactively when requested by the program. See /PASSWORD for a
+ (less secure) method of specifying a password on the command line.
+
+ With Traditional encryption, when decrypting, a password will be
+ checked against header data, and used if it appears to be correct.
+ The correct password will always check out against the header data,
+ but there is a 1-in-256 chance that an incorrect password will as
+ well. (This is a security feature of the PKWARE archive format; it
+ helps prevent brute-force attacks that might otherwise gain a large
+ speed advantage by testing only the header.) In the case that an
+ incorrect password is given but it passes the header test anyway,
+ either an incorrect CRC will be generated for the extracted data or
+ else UnZip will fail during the extraction because the "decrypted"
+ bytes do not constitute a valid compressed data stream.
+
+ If the first password fails the header check on some file, UnZip
+ will prompt for another password, and so on until all files are
+ extracted. If a password is not known, entering a null password
+ (that is, just a carriage return or "Enter") is taken as a signal
+ to skip all further prompting. Only unencrypted files in the
+ archive(s) will thereafter be extracted. (The situation is
+ actually a little more complicated. Some old versions of Zip and
+ ZipCloak allowed null passwords, so UnZip checks each encrypted
+ file to see if the null password works. This may result in "false
+ positives" and extraction errors, as noted above.)
+
+ Archives encrypted with 8-bit-character passwords (for example,
+ passwords with accented European characters) may not be portable
+ across systems or to other archivers. This problem stems from the
+ use of multiple encoding methods for such characters, including
+ Latin-1 (ISO 8859-1) and OEM code page 850. DOS PKZIP 2.04g uses
+ the OEM code page; Windows PKZIP 2.50 uses Latin-1 (and is
+ therefore incompatible with DOS PKZIP; Info-ZIP uses the OEM code
+ page on DOS, OS/2 and Win3.x ports but ISO coding (Latin-1 etc.)
+ everywhere else; and Nico Mak's WinZip 6.x does not allow
+ 8-bit-character passwords at all. UnZip 5.3 (or newer) attempts to
+ use the default character set first (e.g., Latin-1), followed by
+ the alternate one (e.g., OEM code page) to test passwords. On
+ EBCDIC systems, if both of these fail, EBCDIC encoding will be
+ tested as a last resort. (EBCDIC is not tested on non-EBCDIC
+ systems, because there are no known archivers that encrypt using
+ EBCDIC encoding.) ISO character encodings other than Latin-1 are
+ not supported. The new addition of (partial) Unicode (UTF-8)
+ support in UnZip 6.0 has not yet been adapted to the encryption
+ password handling in UnZip. On systems that use UTF-8 as native
+ character encoding, UnZip simply tries decryption with the native
+ UTF-8 encoded password; the built-in attempts to check the password
+ in translated encoding have not yet been adapted for UTF-8 support
+ and will consequently fail.

+
+ Examples
+
+ To use UnZip to extract all members of the archive letters.zip into
+ the current directory and subdirectories below it, creating any
+ subdirectories as necessary:
+
+ unzip letters
+
+ To extract all members of letters.zip into the current directory
+ only:
+
+ unzip /junk_dirs letters
+
+ To test letters.zip, printing only a summary message indicating
+ whether the archive is OK or not:
+
+ unzip /test /quiet letters
+
+ To test all ".zip" archives in the current directory, printing only
+ the summaries:
+
+ unzip /test /quiet *.zip
+
+ (On a Unix system, the wildcard member name would typically need to
+ be quoted to keep a a Unix shell from expanding ("globbing") it.
+ This is not necessary on VMS. However, a name with a slash ("/")
+ character, such as "*/zip*.*", must be quoted. Otherwise, DCL may
+ interpret the slash as introducing a qualifier, causing unexpected
+ behavior or an "%CLI-W-IVQUAL, unrecognized qualifier" error.)
+
+ The following command extracts to standard output all members of
+ letters.zip whose names end in ".tex", auto-converting to the local
+ end-of-line convention, in Stream_LF record format, and piping the
+ output into TYPE /PAGE:
+
+ pipe unzip /screen /text=(auto, stmlf) letters *.tex | \
+ type /page sys$input
+
+ To extract from source.zip all Fortran and C source files (*.f,
+ *.c, *.h) and Makefile into the SYS$SCRATCH directory:
+
+ unzip source.zip *.[fch] Makefile /directory = sys$scratch
+
+ To extract all FORTRAN and C source files, regardless of case (for
+ example, both *.c and *.C, and any makefile, Makefile, MAKEFILE or
+ similar):
+
+ unzip -C source.zip *.[fch] makefile /directory = sys$scratch
+
+ The following command extracts only newer versions of the files
+ already in the current directory, without querying. (Note: Be
+ careful of extracting in one timezone an archive created in
+ another. ZIP archives created by Zip versions before 2.1 contain
+ no timezone information, and a "newer" file from an eastern
+ timezone may, in fact, be older):
+
+ unzip /freshen /existing=new_version sources
+
+ To extract newer versions of the files already in the current
+ directory and to create any files not already there (same caveat as
+ previous example):
+
+ unzip /update /existing=new_version sources
+
+ To display a configuration report showing the program version, the
+ OS and compiler used to build it, a list of optional features
+ enabled at build time, and the values of all the relevant
+ environment variables:
+
+ unzip /verbose
+
+
+UNZIP
+
+ Exit_Status
+
+ UnZip's exit status approximates the exit codes defined by PKWARE.
+ On VMS, UnZip's UNIX-style exit values are translated into
+ VMS-style status codes with facility code 1954 = %x7A2, and with
+ the inhibit-message (%x10000000) and facility-specific (%x00008000)
+ bits set:
+
+ %x17A28001 normal exit
+ %x17A28000 + 16*UnZip_error_code warnings
+ %x17A28002 + 16*UnZip_error_code normal errors
+ %x17A28004 + 16*UnZip_error_code fatal errors
+
+ Note that multiplying the UNIX-style UnZip error code by 16 places
+ it conveniently in the hexadecimal representation of the VMS exit
+ code, "__" in %x17A28__s, where "s" is the severity code. For
+ example, a missing archive might cause UnZip error code 9, which
+ would be transformed into the VMS exit status %X17A28092.
+
+ The UnZip VMS exit codes include severity values which approximate
+ those defined by PKWARE, as shown in the following table:
+
+ VMS UnZip

+UNZIP
+
+ Bugs
+
+ Multi-part archives are not yet supported, except in conjunction
+ with Zip. (All parts must be concatenated together in order, and
+ then "zip -F" (for Zip 2.x) or "zip -FF" (for Zip 3.x) must be
+ performed on the concatenated archive in order to "fix" it. Also,
+ zip 3.0 and later can combine multi-part (split) archives into a
+ combined single-file archive using "zip -s- inarchive -O
+ outarchive". See the zip manual page for more information.) This
+ may be corrected in the next major release.
+
+ Archives read from standard input are not yet supported, except
+ with UnZip (and then only the first member of the archive can be
+ extracted).
+
+ Archives encrypted with 8-bit-character passwords (such as
+ passwords with accented European characters) may not be portable
+ across systems and/or other archivers. See also
+ Encryption_Decryption.
+
+ UnZip's -M ("--more") option tries to take into account automatic
+ wrapping of long lines. However, the code may fail to detect the
+ correct wrapping locations. First, TAB characters (and similar
+ control sequences) are not taken into account, they are handled as
+ ordinary printable characters. Second, depending on the actual
+ system type, UnZip may not detect the true terminal/emulator
+ geometry, but instead may rely on "commonly used" default
+ dimensions. The correct handling of tabs would require the
+ implementation of a query for the actual tab setup on the output
+ terminal/emulator.
+
+ [Unix] Unix special files such as FIFO buffers (named pipes), block
+ devices and character devices are not restored even if they are
+ somehow represented in the archive, nor are hard-linked files
+ relinked. Basically, the only file types restored by UnZip are
+ regular files, directories, and symbolic (soft) links.
+
+ [OS/2] Extended attributes for existing directories are only
+ updated if the -o ("--overwrite") option is given. This is a
+ limitation of the operating system; because directories only have a
+ creation time associated with them, UnZip has no way to determine
+ whether the stored attributes are newer or older than those on
+ disk. In practice this may mean a two-pass approach is required:
+ first unpack the archive normally (with or without
+ freshening/updating existing files), then overwrite just the
+ directory entries (for example, "unzip -o foo */").

+
+ ZipInfo_mode
+
+ When /ZIPINFO is specified, the program runs in ZipInfo mode.
+ Remaining options are interpreted as ZipInfo options. If used,
+ /ZIPINFO must be the first qualifier on the command line.
+
+ ZipInfo reports detailed information about a ZIP archive and its
+ members. This information may include file access permissions,
+ compression method, encryption method, version and operating system
+ (or file system) of the archive-creating program, and so on. The
+ default behavior (with no options) is to show a single-line entry
+ for each member in the archive, with a header and a trailer
+ providing summary information for the entire archive. The format
+ is a cross between Unix "ls -l" and "UNZIP /LIST /VERBOSE" output.
+ See Detailed_Description. ZipInfo is the same program as UnZip.
+ (On Unix, "zipinfo" may be a link to "unzip". On VMS, "ZIPINFO" is
+ normally a DCL symbol defined as "''UNZIP' /ZIPINFO".) However,
+ ZipInfo support may have been disabled when UnZip was built.
+
+ Format:
+
+ ZIPINFO [/zipinfo_options] [file[.zip]] [member [,...]]
+
+ UNZIP /ZIPINFO [/zipinfo_options] [file[.zip]] [member [,...]]
+

+UNZIP
+
+ ZipInfo_mode
+
+ Command_Parameters
+
+ file[.zip]
+
+ File path/name of a ZIP archive. A wildcard name may be used to
+ specify multiple ZIP archives to be processed in one command.
+ On VMS systems, any of the standard wildcards for a
+ directory/file specification may be used: "...", "*", or "%"
+ (or, since VMS V7.2, "?"). The default archive file
+ specification is ".ZIP".
+
+ Note that a ".zip" or ".ZIP" file type on an archive is merely a
+ convention, not a requirement. For example, a self-extracting
+ ZIP archive named "fred" or "fred.exe" could be processed as if
+ it were an ordinary archive; just specify the actual file name
+ with its actual name ending (if any), whatever that may be.
+
+ member [,...]
+
+ An optional list of archive members to be processed, separated
+ by commas. If no member list is specified, then all archive
+ members are processed. Unix-like ("globbing") wildcard patterns
+ may be used to match multiple members:
+
+ * Matches a sequence of 0 or more characters.
+ ? Matches exactly 1 character.
+ [...] Matches any single character found inside the
+ brackets. Ranges are specified by a beginning
+ character, a hyphen, and an ending character. If an
+ exclamation point ("!") or a caret ("^") follows the
+ left bracket, then the range of characters within
+ the brackets is complemented. That is, anything
+ except the characters inside the brackets is
+ considered a match. To specify a literal left
+ bracket, use the three-character sequence "[[]".

+ /EXCLUDE=(member [,...])
+ An optional list of archive members to be excluded from processing.
+ Because wildcard characters normally match "/" directory separators
+ (for exceptions see /WILD_SPAN (-W)), this option may be used to
+ exclude any files that are in subdirectories. For example,
+ UNZIP foo *.[ch] /EXCLUDE = */*
+ would extract all C source files (*.c, *.h) in the main directory,
+ but none in any subdirectories. Without the /EXCLUDE option, all C
+ source files in all directories within the archive would be
+ extracted.
+
+ Note that archive members are specified using the Unix-style names
+ which are used in ZIP archives, not VMS-style names.
+
+
+UNZIP

+
+ /HEADER (-h)
+
+ Include a header in the report, showing the archive name, the

+
+ For the Unix-format reports (options /LONG, /MEDIUM, /SHORT), the
+ header is included by default, if no archive members are specified.
+ If /HEADER is specified alone, that is, without one of the
+ Unix-format options, and without a member list, then only the

+
+ /MATCH (-C, -W)
+
+ /MATCH=(keyword, ...)
+
+ Specifies name-matching behavior for names in the member list and
+ the /EXCLUDE excluded-member list on the command line.
+
+ The optional keywords and values are:
+
+ CASE=BLIND Name matching is case-insensitive. (-C)
+ CASE=SENSITIVE Name matching is case-sensitive. (Default.)
+
+ By default, case-sensitive matching is done. For example,
+ specifying "makefile" on the command line will match only
+ "makefile" in the archive, not "Makefile" or "MAKEFILE". On many
+ systems, the local file system is case-insensitive, so
+ case-insensitive name matching would be more natural. With
+ /MATCH=CASE=BLIND, "makefile" would match "makefile", "Makefile",
+ or "MAKEFILE".
+
+ /MATCH does not affect the search for the ZIP archive file(s), nor
+ the matching of archive members to existing files on the extraction
+ path. So, on a case-sensitive file system, UnZip will never try to
+ overwrite a file "FOO" when extracting a member named "foo"!
+
+ [WILD_STOP_AT_DIR] If the C macro WILD_STOP_AT_DIR is defined at
+ build time, then an additional keyword is allowed:
+
+ NOWILD_MATCH_SLASH Wildcards stop at directory slash. (-W)
+ WILD_MATCH_SLASH Wildcards match directory slash. (Default.)
+
+ By default, the wildcard characters "?" (single-character wildcard)
+ and "*" (multi-character wildcard) match any character in a member
+ path/name. /MATCH=NOWILD_MATCH_SLASH (-W) modifies the
+ pattern-matching behavior for archive members so that both "?"
+ (single-character wildcard) and "*" (multi-character wildcard) do
+ not match the directory separator character "/". (The
+ two-character sequence "**" acts as a multi-character wildcard that
+ includes the directory separator in its matched characters.) For
+ example, with /MATCH=NOWILD_MATCH_SLASH:
+ "*.c" matches "foo.c" but not "mydir/foo.c"
+ "**.c" matches both "foo.c" and "mydir/foo.c"
+ "*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"
+ "??*/*" matches "ab/foo" and "abc/foo"
+ but not "a/foo" or "a/b/foo"
+
+ This modified behavior is equivalent to the pattern matching style
+ used by the shells of some of \fIUnZip\fP's supported target OSs
+ (one example is Acorn RISC OS). This option may not be available
+ on systems where the Zip archive's internal directory separator
+ character "/" is allowed as regular character in native operating
+ system filenames.
+
+ [non-VMS] (Currently, UnZip uses the same pattern matching rules
+ for both wildcard archive file name specifications and archive
+ member selection patterns on most system types. For systems
+ allowing "/" as regular filename character, the -W option would not
+ work as expected on a wildcard file name specification.)

+ pressing the Enter (Return) key or the space bar. UnZip can be
+ terminated by pressing the "Q" key and, on some systems, the
+ Enter/Return key. Unlike Unix more(1), there is no
+ forward-searching or editing capability. Also, UnZip doesn't
+ notice if long lines wrap at the edge of the screen, effectively
+ resulting in the printing of two or more lines and the likelihood
+ that some text will scroll off the top of the screen before being

+
+ For the Unix-format reports (/LONG, /MEDIUM, /SHORT), the totals

+ ZipInfo_mode
+
+ Detailed_Description
+
+ ZipInfo has three basic report formats, providing different degrees
+ of detail in the information about the members of an archive: a
+ simple list of names (/ONE_LINE (-1, -2)), a Unix ls-style listing
+ (/LONG (-l), /MEDIUM (-m), /SHORT (-s)), and a very detailed
+ analysis (/VERBOSE (-v)). Some of the information, such as file
+ sizes, is easy to interpret. Some of the information involves
+ fairly obscure details of ZIP archive structure. ZIP archive
+ structure is documented in the PKWARE Inc. APPNOTE.TXT:
+ http://www.pkware.com/documents/casestudies/APPNOTE.TXT
+
+ The table below shows some typical /LONG report entries:

+ RWED,RE, 3.1 vms 6656 bx 2295 defN 07-Aug-15 14:12 it/T.EXE;8
+
+ Field 1 (Perm/Prot) shows the file permission/protection
+ attributes, formatted according to the original operating system or
+ file system where the archive was created.
+
+ Field 2 (Zver) shows the (approximate) version of the Zip program
+ which created the archive.
+
+ Field 3 (Ofs) shows the original operating system where the archive
+ was created, or the file system on which the member file was
+ stored.
+
+ Field 4 (UncSize) shows the original, uncompressed file size.
+
+ Field 5 (At) shows some archive member attributes, as detailed in
+ the tables below. The first character indicates whether a file was
+ binary or text, and whether it was encrypted. The second character
+ indicates the presence of a data descriptor and/or an extra field
+ in the member data.
+
+ | File Type Extra Field |
+ First char | binary text yes no | Second char
+ --------------+-------+----- ------+-----+--------------------
+ Encrypted no | b t x - | no Data Descriptor
+ yes | B T X l | yes
+
+ A Data Descriptor holds CRC and size data at an alternate place in
+ the archive (after processed member data instead of before), and is
+ normally used when the archiving program can't seek in the output
+ archive data/file. An Extra Field can hold a wide variety of data,
+ including 64-bit file sizes, many kinds of OS-specific attribute
+ data, UTC times, and so on.
+
+ Field 6 (CmpSize) shows the compressed file size. With /MEDIUM,
+ this field shows the compression fraction as a percentage. With
+ /SHORT (the default), this field is omitted. This compressed size
+ value (unlike the one in an "UNZIP /LIST" report) includes all the
+ overhead resulting from Traditional encryption.
+
+ Field 7 (Cmth) shows the compression method used. Note that AES_WG
+ encryption is treated as a compression method here. Not all of the
+ methods shown in the table below are supported. (Some are
+ obsolete.)

+
+UNZIP
+
+ ZipInfo_mode
+
+ Environment_Options
+
+ ZipInfo's default behavior may be modified by placing Unix-style
+ command-line options in an environment variable. (The VMS CLI
+ translator acts only on the command line itself, not on the
+ environment variables.) This can be done with any option, but it is
+ probably most useful options like -T (/DECIMAL_TIME, decimal time
+ format) or one of the non-default Unix format options: -l (/LONG),
+ -m (/MEDIUM).
+
+ For ZipInfo ("UNZIP /ZIPINFO", ZIPINFO), the environment variable
+ name on VMS is ZIPINFO_OPTS (non-VMS: ZIPINFO). For compatibility
+ with Zip, if ZIPINFO (ZIPINFO_OPTS on VMS) is not defined, then
+ ZipInfo will use ZIPINFOOPT the same way.
+
+ For example, to make the default format the long Unix format
+ instead of the short Unix format, one could use commands like the
+ following (with quotation to preserve lower case in DCL):
+
+ define ZIPINFO_OPTS "-l" ! Logical name, or
+ ZIPINFO_OPTS = "-l" ! DCL symbol. (Either works.)
+
+ Environment options are treated the same as any other Unix-style
+ command-line options, except that they are effectively the first
+ options on the command line. Generally, the VMS CLI translator
+ will override an environment option if an explicit corresponding
+ VMS-style qualifier is specified.
+
+ The examples show short (one-character) options, but long ("--")
+ options are also allowed.

+
+ To produce a basic, long-format listing (not verbose), including
+ header and totals lines, use /LONG:
+
+ zipinfo /long zip31c.zip
+
+ To list the complete contents of the archive without header and
+ totals lines, either negate the /HEADER and /TOTALS qualifiers or
+ else specify the contents explicitly:
+
+ zipinfo /noheader /nototals zip31c.zip
+ zipinfo zip31c.zip *
+
+ (On a Unix system, the wildcard member name would typically need to
+ be quoted to keep a a Unix shell from expanding ("globbing") it.
+ This is not necessary on VMS. However, a name with a slash ("/")
+ character, such as "*/zip*.*", must be quoted. Otherwise, DCL may
+ interpret the slash as introducing a qualifier, causing unexpected
+ behavior or an "%CLI-W-IVQUAL, unrecognized qualifier" error.)
+
+ To list information on a single archive member, in medium format,
+ specify the member name explicitly:
+
+ zipinfo /medium unzip60.zip */unshrink.c
+
+ On a VMS system, one could use /DECIMAL_TIME along with an external
+ sorting program to get a listing of files in the archive in
+ date-time order:
+
+ pipe zipinfo /decimal_time /long /noheader /nototals zip31c.zip | -
+ sort sys$input sys$output /key = (position:47, size:15, descend)
+
+ For a /LONG (-l) format report, the date-time field should begin at
+ position 47; for /MEDIUM (-m), 42; for /SHORT (-s), 38. HELP SORT
+ [/KEY] should lead to an explanation of the various SORT options.
+ (Unlike Unix, VMS does not include a useful "head" or "tail"
+ program.)
+
+ On a Unix system, one could use the -T option along with an
+ external sorting program (and another filter like "head" or "tail")
+ to get a listing of the least or most recently modified files in
+ the archive:
+
+ zipinfo -l -T -h- -t- zip31c.zip | sort -k 8 | head -12
+ zipinfo -l -T -h- -t- zip31c.zip | sort -r -k 8 | head -12
+
+ The "sort" option "-k 8" tells it to sort on field 8, which is the
+ date-time field in a long- or medium-format (-l, -m) ZipInfo
+ report. (Use "-k 7" for the short (-s) format.) The -r option
+ reverses the default smallest-to-largest sort order.

+
+ Bugs
+
+ As with UnZip, ZipInfo's /PAGE (-M) option is overly simplistic in
+ its handling of screen output. As noted above, it fails to detect
+ the wrapping of long lines and may thereby cause lines at the top
+ of the screen to be scrolled off before being read. ZipInfo should
+ detect and treat each occurrence of line-wrap as one additional
+ line printed. This requires knowledge of the screen's width as
+ well as its height. In addition, ZipInfo should detect the true
+ screen geometry on all systems.
+
+ The interactions among the various listing format, header, and
+ trailer options (/HEADER, /LONG, /MEDIUM, /SHORT, /TOTALS) are
+ unnecessarily complex and should be simplified, despite the
+ potential disruption to current users.

Zip and UnZip have long supported a relatively weak encryption method,
which we call Traditional ZIP encryption. The source code for Tradi-
tional encryption is included in the source kits, and support for Tra-
- ditional encryption is enabled by default. (Build-time C macros:
- IZ_CRYPT_TRAD, NO_CRYPT.)

- is intended to be compatible with that used by the WinZip program.
- WinZip is a registered trademark of WinZip International LLC.) The
- source code for AES_WG encryption is distributed in a separate kit (for
- export control reasons), and support for AES_WG encryption must be

-/* All currently known variants of WIN32 operating systems (Windows 95/98,
- * WinNT 3.x, 4.0, 5.x) have a nasty bug in the OS kernel concerning
- * conversions between UTC and local time: In the time conversion functions
- * of the Win32 API, the timezone offset (including seasonal daylight saving
- * shift) between UTC and local time evaluation is erratically based on the
- * current system time. The correct evaluation must determine the offset
- * value as it {was/is/will be} for the actual time to be converted.
- *
- * Newer versions of MS C runtime lib's stat() returns utc time-stamps so
- * that localtime(timestamp) corresponds to the (potentially false) local
- * time shown by the OS' system programs (Explorer, command shell dir, etc.)
- * The RSXNT port follows the same strategy, but fails to recognize the
- * access-time attribute.
- *
- * For the NTFS file system (and other filesystems that store time-stamps
- * as UTC values), this results in st_mtime (, st_{c|a}time) fields which
- * are not stable but vary according to the seasonal change of "daylight
- * saving time in effect / not in effect".
- *
- * Other C runtime libs (CygWin), or the crtdll.dll supplied with Win9x/NT
- * return the unix-time equivalent of the UTC FILETIME values as got back
- * from the Win32 API call. This time, return values from NTFS are correct
- * whereas utimes from files on (V)FAT volumes vary according to the DST
- * switches.
- *
- * To achieve timestamp consistency of UTC (UT extra field) values in
- * Zip archives, the Info-ZIP programs require work-around code for
- * proper time handling in stat() (and other time handling routines).
- *
- * However, nowadays most other programs on Windows systems use the
- * time conversion strategy of Microsofts C runtime lib "msvcrt.dll".
- * To improve interoperability in environments where a "consistent" (but
- * false) "UTC<-->LocalTime" conversion is preferred over "stable" time
- * stamps, the Info-ZIP specific time conversion handling can be
- * deactivated by defining the preprocessor flag NO_W32TIMES_IZFIX.

The fatal bzip2 error bail-out routine is provided in a separate code
module, so that it can be easily overridden when the UnZip package is
used as a static link library. One example is the WinDLL static library
- usage for building a monolythic binary of the Windows application "WiZ"
- that supports bzip2 both in compression and decompression operations.

- This program reads great gobs of totally nifty information, including the
- central directory stuff, from ZIP archives ("zipfiles" for short). It
- started as just a testbed for fooling with zipfiles, but at this point it
- is actually a useful utility. It also became the basis for the rewrite of
- UnZip (3.16 -> 4.0), using the central directory for processing rather than
- the individual (local) file headers.

- As of ZipInfo v2.0 and UnZip v5.1, the two programs are combined into one.
- If the executable is named "unzip" (or "unzip.exe", depending), it behaves
- like UnZip by default; if it is named "zipinfo" or "ii", it behaves like
- ZipInfo. The ZipInfo behavior may also be triggered by use of unzip's -Z
- option; for example, "unzip -Z [zipinfo_options] archive.zip".

- To enable support for AES encryption, a separate IZ_AES_WG source kit
-is needed. On the Info-ZIP FTP server, the IZ_AES_WG source kit should
-be found in:
+ All the source files needed to enable support for AES encryption are
+included in a normal UnZip source kit. Information about AES encryption
+in Info-ZIP programs can normally be found in the file
+[.aes_wg]README_AES_WG.txt.
- ftp://ftp.info-zip.org/pub/infozip/crypt/
+ For export control reasons, it may be possible to find an UnZip
+ source kit from which these files have been removed. If the files
+ in the [.aes_wg] subdirectory are missing, then the simplest
+ solution is to fetch a complete source kit from any of the usual
+ places. For more information if the [.aes_wg]README_AES_WG.txt
+ file is missing, it should also be available at:
-The latest kit should be:
-
- ftp://ftp.info-zip.org/pub/infozip/crypt/iz_aes_wg.zip
-
-but other, older kits may also be available there. Version
-compatibility information should be included in the IZ_AES_WG
-documentation. The latest version of that should be:
-
- ftp://ftp.info-zip.org/pub/infozip/crypt/README_AES_WG.txt
-
-It might be wise to read that before downloading any particular
-IZ_AES_WG kit.
-
- The IZ_AES_WG kit should be unpacked in the main UnZip directory,
-where it should populate the [.aes_wg] subdirectory. For example, if
-the proper IZ_AES_WG kit is "iz_aes_wg13.zip", then use commands like
-the following:
-
- SET DEFAULT [.unzip61] ! (If not already there.)
- UNZIP [-]iz_aes_wg13.zip
+ ftp://ftp.info-zip.org/pub/infozip/crypt/README_AES_WG.txt
See the "Build" section, below, for details on how to build UnZip
-with AES encryption support.
+with or without AES encryption support.
The IZ_AES_WG code may be too modern for VAX C.

- The UnZip builders for VMS wiil, by default, use the bzip2 source kit
+ By default, the UnZip builders for VMS will use the bzip2 source kit
which is included in the UnZip source kit to create the required bzip2
object library. The builders can also use an existing bzip2 object
library, which is supplied by the user. For details on how to use an
Bzip2 Compression
-----------------
- The optional bzip2 compression method is enabled by default, and the
-required source code is included in the UnZip source kit. By default,
-the builders will use the bzip2 source kit in the [.bzip2] subdirectory
-to build the required bzip2 object library.
+ By default, suppport for the bzip2 compression method is enabled, and
+the required source code is included in the UnZip source kit. By
+default, the builders will use the bzip2 source kit in the [.bzip2]
+subdirectory to build the required bzip2 object library.
- To disable bzip2 compression, add the appropriate option to the
-builder command line. For example:
+ To disable it, add the appropriate option to the builder command
+line. For example:
@ [.vms]build_unzip NOIZ_BZIP2
or:
LZMA and PPMd Compression Methods
---------------------------------
- The optional LZMA and PPMd compression methods (new in UnZip version
-6.1) are enabled by default, and the required source code is included
+ By default, support for the LZMA and PPMd compression methods (new in
+UnZip version 6.1) is enabled. The required source code is included
in the UnZip source kit. The code used to implement these compression
methods is generally written to newer C language standards than the base
Info-ZIP code, so some very old compilers may be unable to build UnZip
if these features are enabled.
- To disable LZMA and/or PPMd compression, add the appropriate option
-to the builder command line. For example:
+ To disable support for LZMA and/or PPMd compression, add the
+appropriate option to the builder command line. For example:
@ [.vms]build_unzip NOLZMA NOPPMD
or:
Advanced Encryption Standard (AES) Encryption
---------------------------------------------
- By default, AES encryption is not enabled. To enable it, first
-download and unpack the separate IZ_AES_WG source kit, as explained
-above. With the IZ_AES_WG source kit unpacked into its [.aes_wg]
-subdirectory, add the appropriate AES_WG option to the builder command
-line. For example:
+ By default, support for AES_WG encryption is enabled if the AES_WG
+source files are present in the [.aes_wg] subdirectory. To disable it,
+add the appropriate option to the builder command line. For example:
- @ [.vms]build_unzip AES_WG
+ @ [.vms]build_unzip NO_AES_WG
or:
- MMS /DESC = [.vms] /MACRO = (AES_WG=1)
+ MMS /DESC = [.vms] /MACRO = (NO_AES_WG=1)
The code used to implement AES_WG encryption is generally written to
newer C language standards than the base Info-ZIP code, so some very old
Traditional Zip Encryption
--------------------------
- By default, Traditional Zip encryption is enabled. To disable it,
-the C macro NO_CRYPT must be defined at build time. This can be done by
-adding NO_CRYPT to the LOCAL_UNZIP symbol/macro. For example:
+ By default, support for Traditional Zip encryption is enabled. To

+can be done by adding NO_CRYPT to the LOCAL_UNZIP symbol/macro. For
+example:
LOCAL_UNZIP == "NO_CRYPT"
@ [.vms]build_unzip
Note that if PROD=dest_dir is specified for a build, then it must
also be specified for other builder operations, such as TEST or
- CLEAN, which also need to know which destination directory to use.
+ CLEAN, which use the destination directory.
Note that PROD=dest_dir has no effect on any automatically built
bzip2 object library, so it's generally safer to use a pre-built
