Such information includes file access permissions, encryption status, type of compression, version and operating system or file system of compressing program, and the like. The default behavior (with no options) is to list single-line entries for each file in the archive, with header and trailer lines providing summary information for the entire ar‐ chive. The format is a cross between Unix ``ls -l'' and ``unzip -v'' output. See **DETAILED** **DESCRIPTION** below. Note that _zipinfo_ is the same program as _unzip_ (under Unix, a link to it); on some systems, however, _zipinfo_ support may have been omitted when _unzip_ was compiled. ## ARGUMENTS _file_[_.zip_] Path of the ZIP archive(s). If the file specification is a wildcard, each matching file is processed in an order determined by the operating system (or file system). Only the filename can be a wildcard; the path itself cannot. Wildcard expressions are similar to Unix [_egrep_(1)](https://www.chedong.com/phpMan.php/man/egrep/1/markdown) (regular) expressions and may contain: * 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 (`!' or `^') follows the left bracket, then the range of char‐ acters within the brackets is complemented (that is, anything _except_ the char‐ acters inside the brackets is considered a match). To specify a verbatim left bracket, the three-character sequence ``[[]'' has to be used. (Be sure to quote any character that might otherwise be interpreted or modified by the operating system, particularly under Unix and VMS.) If no matches are found, the specification is assumed to be a literal filename; and if that also fails, the suffix .zip is appended. Note that self-extracting ZIP files are supported, as with any other ZIP archive; just specify the .exe suffix (if any) explicitly. [_file(s)_] An optional list of archive members to be processed, separated by spaces. (VMS ver‐ sions compiled with VMSCLI defined must delimit files with commas instead.) Regular expressions (wildcards) may be used to match multiple members; see above. Again, be sure to quote expressions that would otherwise be expanded or modified by the operat‐ ing system. [**-x** _xfile(s)_] An optional list of archive members to be excluded from processing. ## OPTIONS ### -1 and zipfile comments are never printed. It is intended for use in Unix shell scripts. ### -2 -h -t comments (**-z**), as well. This option may be useful in cases where the stored filenames are particularly long. ### -s below. ### -m -s that the compression factor, expressed as a percentage, is also listed. ### -l -m pressed size (in bytes) is printed instead of the compression ratio. ### -v ### -h is printed. ### -M end of a screenful of output, _zipinfo_ pauses with a ``--More--'' prompt; the next screenful may be viewed by pressing the Enter (Return) key or the space bar. _zipinfo_ can be terminated by pressing the ``q'' key and, on some systems, the Enter/Return key. Unlike Unix [_more_(1)](https://www.chedong.com/phpMan.php/man/more/1/markdown), there is no forward-searching or editing capability. Also, _zipinfo_ doesn't notice if long lines wrap at the edge of the screen, effectively re‐ sulting in the printing of two or more lines and the likelihood that some text will scroll off the top of the screen before being viewed. On some systems the number of available lines on the screen is not detected, in which case _zipinfo_ assumes the height is 24 lines. ### -t compressed and compressed total sizes , and their overall compression factor is printed; or, if only the totals line is being printed, the values for the entire ar‐ chive are given. The compressed total size does not include the 12 additional header bytes of each encrypted entry. Note that the total compressed (data) size will never match the actual zipfile size, since the latter includes all of the internal zipfile headers in addition to the compressed data. ### -T fault date format is a more standard, human-readable version with abbreviated month names (see examples below). ### -U available, the option **-U** forces _unzip_ to escape all non-ASCII characters from UTF-8 coded filenames as ``#Uxxxx''. This option is mainly provided for debugging purpose when the fairly new UTF-8 support is suspected to mangle up extracted filenames. The option **-UU** allows to entirely disable the recognition of UTF-8 encoded filenames. The handling of filename codings within _unzip_ falls back to the behaviour of previous versions. ### -z ## DETAILED DESCRIPTION _zipinfo_ has a number of modes, and its behavior can be rather difficult to fathom if one isn't familiar with Unix [_ls_(1)](https://www.chedong.com/phpMan.php/man/ls/1/markdown) (or even if one is). The default behavior is to list files in the following format: -rw-rws--- 1.9 unx 2802 t- defX 11-Aug-91 13:48 perms.2660 The last three fields are the modification date and time of the file, and its name. The case of the filename is respected; thus files that come from MS-DOS PKZIP are always capitalized. If the file was zipped with a stored directory name, that is also displayed as part of the filename. The second and third fields indicate that the file was zipped under Unix with version 1.9 of _zip_. Since it comes from Unix, the file permissions at the beginning of the line are printed in Unix format. The uncompressed file-size (2802 in this example) is the fourth field. The fifth field consists of two characters, either of which may take on several values. The first character may be either `t' or `b', indicating that _zip_ believes the file to be text or binary, respectively; but if the file is encrypted, _zipinfo_ notes this fact by capitalizing the character (`T' or `B'). The second character may also take on four values, depending on whether there is an extended local header and/or an ``extra field'' associated with the file (fully explained in PKWare's APPNOTE.TXT, but basically analogous to pragmas in ANSI C--i.e., they provide a standard way to include non-standard information in the archive). If neither exists, the character will be a hyphen (`-'); if there is an extended local header but no ex‐ tra field, `l'; if the reverse, `x'; and if both exist, `X'. Thus the file in this example is (probably) a text file, is not encrypted, and has neither an extra field nor an extended local header associated with it. The example below, on the other hand, is an encrypted bi‐ nary file with an extra field: RWD,R,R 0.9 vms 168 Bx shrk 9-Aug-91 19:15 perms.0644 Extra fields are used for various purposes (see discussion of the **-v** option below) including the storage of VMS file attributes, which is presumably the case here. Note that the file attributes are listed in VMS format. Some other possibilities for the host operating system (which is actually a misnomer--host file system is more correct) include OS/2 or NT with High Performance File System (HPFS), MS-DOS, OS/2 or NT with File Allocation Table (FAT) file sys‐ tem, and Macintosh. These are denoted as follows: -rw-a-- 1.0 hpf 5358 Tl i4:3 4-Dec-91 11:33 longfilename.hpfs -r--ahs 1.1 fat 4096 b- i4:2 14-Jul-91 12:58 EA DATA. SF --w------- 1.0 mac 17357 bx i8:2 4-May-92 04:02 unzip.macr File attributes in the first two cases are indicated in a Unix-like format, where the seven subfields indicate whether the file: (1) is a directory, (2) is readable (always true), (3) is writable, (4) is executable (guessed on the basis of the extension--_.exe_, _.com_, _.bat_, _.cmd_ and _.btm_ files are assumed to be so), (5) has its archive bit set, (6) is hidden, and (7) is a system file. Interpretation of Macintosh file attributes is unreliable because some Macin‐ tosh archivers don't store any attributes in the archive. Finally, the sixth field indicates the compression method and possible sub-method used. There are six methods known at present: storing (no compression), reducing, shrinking, im‐ ploding, tokenizing (never publicly released), and deflating. In addition, there are four levels of reducing (1 through 4); four types of imploding (4K or 8K sliding dictionary, and 2 or 3 Shannon-Fano trees); and four levels of deflating (superfast, fast, normal, maximum com‐ pression). _zipinfo_ represents these methods and their sub-methods as follows: _stor_; _re:1_, _re:2_, etc.; _shrk_; _i4:2_, _i8:3_, etc.; _tokn_; and _defS_, _defF_, _defN_, and _defX_. The medium and long listings are almost identical to the short format except that they add information on the file's compression. The medium format lists the file's compression factor as a percentage indicating the amount of space that has been ``removed'': -rw-rws--- 1.5 unx 2802 t- 81% defX 11-Aug-91 13:48 perms.2660 In this example, the file has been compressed by more than a factor of five; the compressed data are only 19% of the original size. The long format gives the compressed file's size in bytes, instead: -rw-rws--- 1.5 unx 2802 t- 538 defX 11-Aug-91 13:48 perms.2660 In contrast to the _unzip_ listings, the compressed size figures in this listing format denote the complete size of compressed data, including the 12 extra header bytes in case of en‐ crypted entries. Adding the **-T** option changes the file date and time to decimal format: -rw-rws--- 1.5 unx 2802 t- 538 defX 910811.134804 perms.2660 Note that because of limitations in the MS-DOS format used to store file times, the seconds field is always rounded to the nearest even second. For Unix files this is expected to change in the next major releases of [_zip_(1)](https://www.chedong.com/phpMan.php/man/zip/1/markdown) and _unzip_. In addition to individual file information, a default zipfile listing also includes header and trailer lines: ### Archive: OS2.zip 5453 bytes 5 files ,,rw, 1.0 hpf 730 b- i4:3 26-Jun-92 23:40 Contents ,,rw, 1.0 hpf 3710 b- i4:3 26-Jun-92 23:33 makefile.os2 ,,rw, 1.0 hpf 8753 b- i8:3 26-Jun-92 15:29 os2unzip.c ,,rw, 1.0 hpf 98 b- stor 21-Aug-91 15:34 unzip.def ,,rw, 1.0 hpf 95 b- stor 21-Aug-91 17:51 zipinfo.def 5 files, 13386 bytes uncompressed, 4951 bytes compressed: 63.0% The header line gives the name of the archive, its total size, and the total number of files; the trailer gives the number of files listed, their total uncompressed size, and their total compressed size (not including any of _zip_'s internal overhead). If, however, one or more _file(s)_ are provided, the header and trailer lines are not listed. This behavior is also similar to that of Unix's ``ls -l''; it may be overridden by specifying the **-h** and **-t** options explicitly. In such a case the listing format must also be specified explicitly, since **-h** or ### -t both) is listed. See the **EXAMPLES** section below for a semi-intelligible translation of this nonsense. The verbose listing is mostly self-explanatory. It also lists file comments and the zipfile comment, if any, and the type and number of bytes in any stored extra fields. Currently known types of extra fields include PKWARE's authentication (``AV'') info; OS/2 extended at‐ tributes; VMS filesystem info, both PKWARE and Info-ZIP versions; Macintosh resource forks; Acorn/Archimedes SparkFS info; and so on. (Note that in the case of OS/2 extended at‐ tributes--perhaps the most common use of zipfile extra fields--the size of the stored EAs as reported by _zipinfo_ may not match the number given by OS/2's _dir_ command: OS/2 always reports the number of bytes required in 16-bit format, whereas _zipinfo_ always reports the 32-bit storage.) Again, the compressed size figures of the individual entries include the 12 extra header bytes for encrypted entries. In contrast, the archive total compressed size and the average compression ratio shown in the summary bottom line are calculated **without** the extra 12 header bytes of encrypted entries. ## ENVIRONMENT OPTIONS Modifying _zipinfo_'s default behavior via options placed in an environment variable can be a bit complicated to explain, due to _zipinfo_'s attempts to handle various defaults in an intu‐ itive, yet Unix-like, manner. (Try not to laugh.) Nevertheless, there is some underlying logic. In brief, there are three ``priority levels'' of options: the default options; envi‐ ronment options, which can override or add to the defaults; and explicit options given by the user, which can override or add to either of the above. The default listing format, as noted above, corresponds roughly to the "zipinfo -hst" command (except when individual zipfile members are specified). A user who prefers the long-listing format (**-l**) can make use of the _zipinfo_'s environment variable to change this default: Unix Bourne shell: ZIPINFO=-l; export ZIPINFO Unix C shell: setenv ZIPINFO -l OS/2 or MS-DOS: set ZIPINFO=-l VMS (quotes for _lowercase_): define ZIPINFO_OPTS "-l" If, in addition, the user dislikes the trailer line, _zipinfo_'s concept of ``negative op‐ tions'' may be used to override the default inclusion of the line. This is accomplished by preceding the undesired option with one or more minuses: e.g., ``-l-t'' or ``--tl'', in this example. The first hyphen is the regular switch character, but the one before the `t' is a minus sign. The dual use of hyphens may seem a little awkward, but it's reasonably intuitive nonetheless: simply ignore the first hyphen and go from there. It is also consistent with the behavior of the Unix command [_nice_(1)](https://www.chedong.com/phpMan.php/man/nice/1/markdown). As suggested above, the default variable names are ZIPINFO_OPTS for VMS (where the symbol used to install _zipinfo_ as a foreign command would otherwise be confused with the environment variable), and ZIPINFO for all other operating systems. For compatibility with [_zip_(1)](https://www.chedong.com/phpMan.php/man/zip/1/markdown), ZIP‐ INFOOPT is also accepted (don't ask). If both ZIPINFO and ZIPINFOOPT are defined, however, ZIPINFO 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. ## EXAMPLES To get a basic, short-format listing of the complete contents of a ZIP archive _storage.zip_, with both header and totals lines, use only the archive name as an argument to zipinfo: zipinfo storage To produce a basic, long-format listing (not verbose), including header and totals lines, use ### -l zipinfo -l storage 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 storage zipinfo storage \* (where the backslash is required only if the shell would otherwise expand the `*' wildcard, as in Unix when globbing is turned on--double quotes around the asterisk would have worked as well). To turn off the totals line by default, use the environment variable (C shell is as‐ sumed here): setenv ZIPINFO --t zipinfo storage To get the full, short-format listing of the first example again, given that the environment variable is set as in the previous example, it is necessary to specify the **-s** option explic‐ itly, since the **-t** option by itself implies that ONLY the footer line is to be printed: setenv ZIPINFO --t zipinfo -t storage [only totals line] zipinfo -st storage [full listing] The **-s** option, like **-m** and **-l**, includes headers and footers by default, unless otherwise specified. Since the environment variable specified no footers and that has a higher prece‐ dence than the default behavior of **-s**, an explicit **-t** option was necessary to produce the full listing. Nothing was indicated about the header, however, so the **-s** option was suffi‐ cient. Note that both the **-h** and **-t** options, when used by themselves or with each other, override any default listing of member files; only the header and/or footer are printed. This behavior is useful when _zipinfo_ is used with a wildcard zipfile specification; the con‐ tents of all zipfiles are then summarized with a single command. To list information on a single file within the archive, in medium format, specify the file‐ name explicitly: zipinfo -m storage unshrink.c The specification of any member file, as in this example, will override the default header and totals lines; only the single line of information about the requested file will be printed. This is intuitively what one would expect when requesting information about a sin‐ gle file. For multiple files, it is often useful to know the total compressed and uncom‐ pressed size; in such cases **-t** may be specified explicitly: zipinfo -mt storage "*.[ch]" Mak\* To get maximal information about the ZIP archive, use the verbose option. It is usually wise to pipe the output into a filter such as Unix [_more_(1)](https://www.chedong.com/phpMan.php/man/more/1/markdown) if the operating system allows it: zipinfo -v storage | more Finally, to see the most recently modified files in the archive, use the **-T** option in con‐ junction with an external sorting utility such as Unix [_sort_(1)](https://www.chedong.com/phpMan.php/man/sort/1/markdown) (and [_sed_(1)](https://www.chedong.com/phpMan.php/man/sed/1/markdown) as well, in this example): zipinfo -T storage | sort -nr -k 7 | sed 15q The **-nr** option to [_sort_(1)](https://www.chedong.com/phpMan.php/man/sort/1/markdown) tells it to sort numerically in reverse order rather than in tex‐ tual order, and the **-k** **7** option tells it to sort on the seventh field. This assumes the de‐ fault short-listing format; if **-m** or **-l** is used, the proper [_sort_(1)](https://www.chedong.com/phpMan.php/man/sort/1/markdown) option would be **-k** **8**. Older versions of [_sort_(1)](https://www.chedong.com/phpMan.php/man/sort/1/markdown) do not support the **-k** option, but you can use the traditional **+** op‐ tion instead, e.g., **+6** instead of **-k** **7**. The [_sed_(1)](https://www.chedong.com/phpMan.php/man/sed/1/markdown) command filters out all but the first 15 lines of the listing. Future releases of _zipinfo_ may incorporate date/time and filename sorting as built-in options. ## TIPS The author finds it convenient to define an alias _ii_ for _zipinfo_ on systems that allow aliases (or, on other systems, copy/rename the executable, create a link or create a command file with the name _ii_). The _ii_ usage parallels the common _ll_ alias for long listings in Unix, and the similarity between the outputs of the two commands was intentional. ## 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 knowl‐ edge of the screen's width as well as its height. In addition, _zipinfo_ should detect the true screen geometry on all systems. _zipinfo_'s listing-format behavior is unnecessarily complex and should be simplified. (This is not to say that it will be.) ## SEE ALSO [_ls_(1)](https://www.chedong.com/phpMan.php/man/ls/1/markdown), [_funzip_(1)](https://www.chedong.com/phpMan.php/man/funzip/1/markdown), [_unzip_(1)](https://www.chedong.com/phpMan.php/man/unzip/1/markdown), [_unzipsfx_(1)](https://www.chedong.com/phpMan.php/man/unzipsfx/1/markdown), [_zip_(1)](https://www.chedong.com/phpMan.php/man/zip/1/markdown), [_zipcloak_(1)](https://www.chedong.com/phpMan.php/man/zipcloak/1/markdown), [_zipnote_(1)](https://www.chedong.com/phpMan.php/man/zipnote/1/markdown), [_zipsplit_(1)](https://www.chedong.com/phpMan.php/man/zipsplit/1/markdown) ## URL The Info-ZIP home page is currently at or ftp://ftp.info-zip.org/pub/infozip/ . ## AUTHOR Greg ``Cave Newt'' Roelofs.
