Unzip's default behavior may be modified via options placed in an environment variable.This can be done with any option, but it is probably most useful with the -a, -L, -C, -q, -o, or -n modifiers: make unzip auto-convert text files by default, make it convert filenames from uppercase systems to lowercase, make it match names case-insensitively, make it quieter, or make it always.

SYNOPSIS

unzip [-cflptTuvz[abjnoqsCDKLMUVWX$/:^]] file[.zip][file(s) ...] [-xxfile(s) ...] [-dexdir]

DESCRIPTION

unzip will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. A companion program, zip, creates ZIP archives; both programs are compatible with archives created by PKWARE's PKZIP and PKUNZIP for MS-DOS, but in many cases the program options or default behaviors differ.

If the archive contains Unix or Win32 symbolic links, these will be displayed (a 0x80000 in the non-MSDOS external file attributes field with both Unix/Linux/MacOS and PTC MKS Toolkit) or restored to NTFS volumes to point to the same names (existing or not existing) as they were in the source file system. Where the source is on an NTFS volume and target does not exist, a file symbolic link will be created.

Options

-Z

zipinfo mode. If the first option on the command line is -Z, the remaining options are taken to be zipinfo options. See the appropriate manual page for a description of these options.

-A

Macos Unzip Terminal Download

[OS/2, Unix (but not PTC MKS Toolkit) DLL] print extended help for the DLL's programming interface (API).

-c
Macos Unzip Terminal

extract files to stdout/screen (``CRT'). This option is similar to the -p option except that the name of each file is printed as it is extracted, the -a option is allowed, and ASCII-EBCDIC conversion is automatically performed if appropriate. This option is not listed in the unzip usage screen.

-f

freshen existing files, i.e., 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. Note that under many operating systems, the TZ (timezone) environment variable must be set correctly in order for -f and -u to work properly (under Unix the variable is usually set automatically). PTC MKS Toolkit will fall back to the system timezone in the registry if TZ is not set. The reasons for this are somewhat subtle but have to do with the differences between DOS-format file times (always local time) and Unix-format times (always in GMT/UTC) and the necessity to compare the two. A typical TZ value is ``PST8PDT' (US Pacific time with automatic adjustment for Daylight Savings Time or ``summer time').

-l

list archive files (short format). The names, uncompressed file sizes and modification dates and times of the specified files are printed, along with totals for all files specified. If UnZip was compiled with OS2_EAS defined, the -l option also lists columns for the sizes of stored OS/2 extended attributes (EAs) and OS/2 access control lists (ACLs). In addition, the zipfile comment and individual file 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 -L option was given, the filename is converted to lowercase and is prefixed with a caret (^).

-v

list zipfile information in verbose, multi-page format.

-p

extract files to pipe (stdout). Nothing but the file data is sent to stdout, and the files are always extracted in binary format, just as they are stored (no conversions).

-t

test archive files. This option extracts each specified file in memory and compares the CRC (cyclic redundancy check, an enhanced checksum) of the expanded file with the original file's stored CRC value.

-T

[most OSes] set the timestamp on the archive(s) to that of the newest file in each one. This corresponds to zip's -go option except that it can be used on wildcard zipfiles (e.g., ``unzip -T *.zip') and is much faster.

-u

update existing files and create new ones if needed. This option performs the same function as the -f option, extracting (with query) files that are newer than those with the same name on disk, and in addition it extracts those files that do not already exist on disk. See -f above for information on setting the timezone properly.

-v

list archive files (verbose format) or show diagnostic version info. This option has evolved and now behaves as both an option and a modifier. As an option it has two purposes: when a zipfile is specified with no other options, -v lists archive files verbosely, adding to the basic -l info the compression method, compressed size, compression ratio and 32-bit CRC. In contrast to most of the competing utilities, unzip removes the 12 additional header bytes of encrypted entries from the compressed size numbers. Therefore, compressed size and compression ratio figures are independent of the entry's encryption status and show the correct compression performance. (The complete size of the encrypted compressed data stream for zipfile entries is reported by the more verbose zipinfo reports, see the separate manual.) When no zipfile is specified (that is, the complete command is simply ``unzip -v'), a diagnostic screen is printed. In addition to the normal header with release date and version, unzip lists the home Info-ZIP ftp site and where to find a list of other ftp and non-ftp sites; the target operating system for which it was compiled, as well as (possibly) the hardware on which it was compiled, the compiler and version used, and the compilation date; any special compilation options that might affect the program's operation (see also DECRYPTION below); and any options stored in environment variables that might do the same (see ENVIRONMENT below). As a modifier it works in conjunction with other options (e.g., -t) to produce more verbose or debugging output; this is not yet fully implemented but will be in future releases.

-z

display only the archive comment.

Modifiers

-a

convert text files. Ordinarily all files are extracted exactly as they are stored (as ``binary' files). The -a option causes files identified by zip as text files (those with the `t' label in zipinfo listings, rather than `b') to be automatically extracted as such, converting line endings, end-of-file characters and the character set itself as necessary. (For example, Unix files use line feeds (LFs) for end-of-line (EOL) and have no end-of-file (EOF) marker; Macintoshes use carriage returns (CRs) for EOLs; and most PC operating systems use CR+LF for EOLs and control-Z for EOF. In addition, IBM mainframes and the Michigan Terminal System use EBCDIC rather than the more common ASCII character set, and NT supports Unicode.) Note that zip's identification of text files is by no means perfect; some ``text' files may actually be binary and vice versa. unzip therefore prints ``[text]' or ``[binary]' as a visual check for each file it extracts when using the -a option. The -aa option forces all files to be extracted as text, regardless of the supposed file type. On VMS, see also -S.

-b

treat all files as binary (no text conversions). This is a shortcut for -a.

-B

[when compiled with UNIXBACKUP defined (as it is with PTC MKS Toolkit)] save a backup copy of each overwritten file. The backup file is gets the name of the target file with a tilde and optionally a unique sequence number (up to 5 digits) appended. The sequence number is applied whenever another file with the original name plus tilde already exists. When used together with the 'overwrite all' option -o, numbered backup files are never created. In this case, all backup files are named as the original file with an appended tilde, existing backup files are deleted without notice. This feature works similarly to the default behavior of emacs in many locations.

Example: the old copy of ``foo' is renamed to ``foo~'.

Warning: Users should be aware that the -B option does not prevent loss of existing data under all circumstances. For example, when unzip is run in overwrite-all mode, an existing ``foo~' file is deleted before unzip attempts to rename ``foo' to ``foo~'. When this rename attempt fails (because of a file locks, insufficient privileges, or ...), the extraction of ``foo~' gets cancelled, but the old backup file is already lost. A similar scenario takes place when the sequence number range for numbered backup files gets exhausted (99999, or 65535 for 16-bit systems). In this case, the backup file with the maximum sequence number is deleted and replaced by the new backup version without notice.

-C

use case-insensitive matching for the selection of archive entries from the command-line list of extract selection patterns. unzip's philosophy is ``you get what you ask for' (this is also responsible for the -L/-U change; see the relevant options below). Because some file systems are fully case-sensitive (notably those under the Unix operating system) and because both ZIP archives and unzip itself are portable across platforms, unzip's default behavior is to match both wildcard and literal filenames case-sensitively. That is, specifying ``makefile' on the command line will only match ``makefile' in the archive, not ``Makefile' or ``MAKEFILE' (and similarly for wildcard specifications). Since this does not correspond to the behavior of many other operating/file systems (for example, OS/2 HPFS, which preserves mixed case but is not sensitive to it), the -C option may be used to force all filename matches to be case-insensitive. In the example above, all three files would then match ``makefile' (or ``make*', or similar). The -C option affects file specs in both the normal file list and the excluded-file list (xlist).

Please note that the -C option does neither affect the search for the zipfile(s) nor the matching of archive entries to existing files on the extraction path. On a case-sensitive file system, unzip will never try to overwrite a file ``FOO' when extracting an entry ``foo'!

Mac os unzip terminal
-D

skip restoration of timestamps for extracted items. Normally, unzip tries to restore all meta-information for extracted items that are supplied in the Zip archive (and do not require privileges or impose a security risk). By specifying -D, unzip is told to suppress restoration of timestamps for directories explicitly created from Zip archive entries. This option only applies to ports that support setting timestamps for directories (currently ATheOS, BeOS, MacOS, OS/2, Unix, VMS, Win32, PTC MKS Toolkit, for other unzip ports, -D has no effect). The duplicated option -DD forces suppression of timestamp restoration for all extracted entries (files and directories). This option results in setting the timestamps for all extracted entries to the current time.

On VMS, the default setting for this option is -D for consistency with the behaviour of BACKUP: file timestamps are restored, timestamps of extracted directories are left at the current time. To enable restoration of directory timestamps, the negated option --D should be specified. On VMS, the option -D disables timestamp restoration for all extracted Zip archive items. (Here, a single -D on the command line combines with the default -D to do what an explicit -DD does on other systems.)

-E

[MacOS only] display contents of MacOS extra field during restore operation

-F

[non-Acorn systems supporting long filenames with embedded commas, and only if compiled with ACORN_FTYPE_NFS defined (which PTC MKS Toolkit does not)] translate filetype information from ACORN RISC OS extra field blocks into a NFS filetype extension and append it to the names of the extracted files. (When the stored filename appears to already have an appended NFS filetype extension, it is replaced by the info from the extra field.

-i

[MacOS only] ignore filenames stored in MacOS extra fields. Instead, the most compatible filename stored in the generic part of the entry's header is used.

-j

junk paths. The archive's directory structure is not recreated; all files are deposited in the extraction directory (by default, the current one).

-J

[MacOS only] ignore MacOS extra fields. All Macintosh specific info is skipped.. Embedded control characters in file names might have nasty side effects when displayed on screen by some listing code without sufficient filtering. And, for ordinary users, it may be difficult to handle such file names (e.g. when trying to specify it for open, copy, move, or delete operations). Therefore, unzip applies a filter by default that removes potentially dangerous control characters from the extracted file names. The -^ option allows to override this filter in the rare case that embedded filename control characters are to be intentionally restored.

-2

[VMS] force unconditionally conversion of file names to ODS2-compatible names. The default is to exploit the destination file system, preserving case and extended file name characters on an ODS5 destination file system; and applying the ODS2-compatibility file name filtering on an ODS2 destination file system.

ENVIRONMENT

unzip's default behavior may be modified via options placed in an environment variable. This can be done with any option, but it is probably most useful with the -a, -L, -C, -q, -o, or -n modifiers: make unzip auto-convert text files by default, make it convert filenames from uppercase systems to lowercase, make it match names case-insensitively, make it quieter, or make it always overwrite or never overwrite files as it extracts them. For example, to make unzip act as quietly as possible, only reporting errors, one would use one of the following commands:

Unix (and PTC MKS Toolkit) Bourne shell:

Unix (and PTC MKS Toolkit) C shell:

OS/2 or MS-DOS:

VMS (quotes for lowercase):

Environment options are, in effect, considered to be just like 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 the ``minus operator' to remove it. For instance, to override one of the quiet-flags in the example above, use the command

The first hyphen is the normal switch character, and the second is a minus sign, acting on the q option. Thus the effect here is to cancel one quantum of quietness. To cancel both quiet flags, two (or more) minuses may be used:

(the two are equivalent). This may seem awkward or confusing, but it is reasonably intuitive: just ignore the first hyphen and go from there. It is also consistent with the behavior of Unix nice.

As suggested by the examples above, the default variable names are UNZIP_OPTS for VMS (where the symbol used to install unzip as a foreign command would otherwise be confused with the environment variable), and UNZIP for all other operating systems. For compatibility with zip, UNZIPOPT is also accepted (don't ask). If both UNZIP and UNZIPOPT are defined, however, UNZIP takes precedence. unzip's diagnostic option (-v with no zipfile name) can be used to check the values of all four possible unzip and zipinfo environment variables.

The timezone variable (TZ) should be set according to the local timezone in order for the -f and -u to operate correctly. See the description of -f above for details. This variable may also be necessary to get timestamps of extracted files to be set correctly. The WIN32 (2012/8.1/2012R2/2016/2019 and the PTC MKS Toolkit) port of unzip gets the timezone configuration from the registry, assuming it is correctly set in the Control Panel. The TZ variable is ignored for WIN32 but will override teh registry for PTC MKS Toolkit.

TK_ARCHIVE_CHARSET will instruct unzip how to interpret file names and commants in an archive. Settings are:

The value must be one of ASCII_ANSI, ASCII_OEM, or UTF-8 (or their equivalents) as described in the File Character Formats section of the unicode reference page.

Setting TK_ARCHIVE_CHARSET to ASCII_ANSI or ASCII_OEM is somewhat like to the LANG environment variable on UNIX in that it tailors the interpretation of the character set in use for file names and comments inside the zip archive.

When this variable is unset or it is set to a value other than those listed earlier, the default ANSI character set is used.

DECRYPTION

Encrypted archives are fully supported by Info-ZIP software, but due to United States export restrictions, de-/encryption support might be disabled in your compiled binary. However, since spring 2000, US export restrictions have been liberated, and our source archives do now include full crypt code. In case you need binary distributions with crypt support enabled, see the file ``WHERE' in any Info-ZIP source or binary distribution for locations both inside and outside the US.

Some compiled versions of unzip may not support decryption (The PTC MKS Toolkit version is compiled with decryption enabled). To check a version for crypt support, either attempt to test or extract an encrypted archive, or else check unzip's diagnostic screen (see the -v option above) for ``[decryption]' as one of the special compilation options.

As noted above, the -P option may be used to supply a password on the command line, but at a cost in security. The preferred decryption method is simply to extract normally; if a zipfile member is encrypted, unzip will prompt for the password without echoing what is typed. unzip continues to use the same password as long as it appears to be valid, by testing a 12-byte header on each file. The correct password will always check out against the header, but there is a 1-in-256 chance that an incorrect password will as well. (This is a security feature of the PKWARE zipfile 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. (In fact, that's not quite true; older 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 passwords (for example, passwords with accented European characters) may not be portable across systems and/or 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 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 (partially) Unicode (resp. 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:

To extract all members of letters.zip into the current directory only:

To test letters.zip, printing only a summary message indicating whether the archive is OK or not:

To test all zipfiles in the current directory, printing only the summaries:

(The backslash before the asterisk is only required if the shell expands wildcards, as in Unix; double quotes could have been used instead, as in the source examples below.) To extract to standard output all members of letters.zip whose names end in .tex, auto-converting to the local end-of-line convention and piping the output into more:

To extract the binary file paper1.dvi to standard output and pipe it to a printing program:

To extract all FORTRAN and C source files--*.f, *.c, *.h, and Makefile--into the /tmp directory:

(the double quotes are necessary only in Unix (and PTC MKS Toolkit shells) and only if globbing is turned on). To extract all FORTRAN and C source files, regardless of case (e.g., both *.c and *.C, and any makefile, Makefile, MAKEFILE or similar):

To extract any such files but convert any uppercase MS-DOS or VMS names to lowercase and convert the line-endings of all of the files to the local standard (without respect to any files that might be marked ``binary'):

To extract only newer versions of the files already in the current directory, without querying (NOTE: be careful of unzipping in one timezone a zipfile created in another--ZIP archives other than those created by Zip 2.1 or later contain no timezone information, and a ``newer' file from an eastern timezone may, in fact, be older):

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):

To display a diagnostic screen showing which unzip and zipinfo options are stored in environment variables, whether decryption support was compiled in, the compiler with which unzip was compiled, etc.:

(Extra minuses in options don't hurt.)

TIPS

The current maintainer, being a lazy sort, finds it very useful to define a pair of aliases: tt for ``unzip -tq' and ii for unzip-Z (or zipinfo). One may then simply type ``tt zipfile' to test an archive, something that is worth making a habit of doing. With luck unzip will report ``No errors detected in compressed data of zipfile.zip,' after which one may breathe a sigh of relief.

The maintainer also finds it useful to set the UNZIP environment variable to ``-aL' and is tempted to add ``-C' as well. His ZIPINFO variable is set to ``-z'.

DIAGNOSTICS

The exit status (or error level) approximates the exit codes defined by PKWARE and takes on the following values, except under VMS:

0

normal; no errors or warnings detected.

1

one or more warning errors were encountered, but processing completed successfully anyway. This includes zipfiles where one or more files was skipped due to unsupported compression method or encryption with an unknown password.

2

a generic error in the zipfile format was detected. Processing may have completed successfully anyway; some broken zipfiles created by other archivers have simple work-arounds.

3

a severe error in the zipfile format was detected. Processing probably failed immediately.

4

unzip was unable to allocate memory for one or more buffers during program initialization.

5

unzip was unable to allocate memory or unable to obtain a tty to read the decryption password(s).

6

unzip was unable to allocate memory during decompression to disk.

7

unzip was unable to allocate memory during in-memory decompression.

8

[currently not used]

9

the specified zipfiles were not found.

10

invalid options were specified on the command line.

11

no matching files were found.

50

the disk is (or was) full during extraction.

51

the end of the ZIP archive was encountered prematurely.

80

the user aborted unzip prematurely with control-C (or similar)

81

testing or extraction of one or more files failed due to unsupported compression methods or unsupported decryption.

82

no files were found due to bad decryption password(s). (If even one file is successfully processed, however, the exit status is 1.)

VMS interprets standard Unix (or PC) return values as other, scarier-looking things, so unzip instead maps them into VMS-style status codes. The current mapping is as follows: 1 (success) for normal exit, 0x7fff0001 for warning errors, and (0x7fff000? + 16*normal_unzip_exit_status) for all other errors, where the `?' is 2 (error) for unzip values 2, 9-11 and 80-82, and 4 (fatal error) for the remaining ones (3-8, 50, 51). In addition, there is a compilation option to expand upon this behavior: defining RETURN_CODES results in a human-readable explanation of what the error status means.

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 3 manual page for more information.) This will definitely be corrected in the next major release. Archives read from standard input are not yet supported, except with funzip (and then only the first member of the archive can be extracted).

Archives encrypted with 8-bit passwords (e.g., passwords with accented European characters) may not be portable across systems and/or other archivers. See the discussion in DECRYPTION above.

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 / OS port, unzip may not detect the true screen geometry but rather rely on 'commonly used' default dimensions. The correct handling of tabs would require the implementation of a query for the actual tabulator setup on the output console.

Dates, times and permissions of stored directories are not restored except under Unix and PTC MKS Toolkit. (On Windows NT and successors, timestamps are now restored.)

[MS-DOS] When extracting or testing files from an archive on a defective floppy diskette, if the ``Fail' option is chosen from DOS's ``Abort, Retry, Fail?' message, older versions of unzip may hang the system, requiring a reboot. This problem appears to be fixed, but control-C (or control-Break) can still be used to terminate unzip.

Under DEC Ultrix, unzip would sometimes fail on long zipfiles (bad CRC, not always reproducible). This was apparently due either to a hardware bug (cache memory) or an operating system bug (improper handling of page faults?). Since Ultrix has been abandoned in favor of Digital Unix (OSF/1), this may not be an issue anymore.

[Unix and PTC MKS Toolkit] 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 zipfile, 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 all') 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 (e.g., ``unzip -o foo */').

[VMS] When extracting to another directory, only the [.foo] syntax is accepted for the -d option; the simple Unix foo syntax is silently ignored (as is the less common VMS foo.dir syntax).

[VMS] When the file being extracted already exists, unzip's query only allows skipping, overwriting or renaming; there should additionally be a choice for creating a new version of the file. In fact, the ``overwrite' choice does create a new version; the old version is not overwritten or deleted.
