X  Additional copyright information:
X
X     BILF (distributed with the VMS stuff) is copyrighted by Rahul Dhesi,
X     but it is freely distributable.
X
X     The functions extract_or_test_files() and store_info() in extract.c,
X     do_string() and return_VMS() in misc.c, VMS version of echo() in
X     file_io.c, and find_end_central_dir() in unzip.c, were written by
X     Greg Roelofs and subsequently modified by many others via Info-ZIP.
X     I do not claim a copyright on these routines, but I do ask that no
X     one else do so either, :-) and that anyone using them in other pro-
X     grams note their source.
X
X     The function decrypt_member() in extract.c and the password functions
X     in file_io.c were written by Mark Adler.
X
X     The function mapped_name() in mapname.c was written by David Kirschbaum,
X     based on the XXU program by Frank Da Cruz.
X
X     Most of the remaining routines have contributions from all of us, and
X     show it. :-)
X
X===============================================================================
X
X   Info-ZIP comments:
X
X   Info-ZIP has very little interest in legal matters, aside from the usual
X   "CYA" sense.  In particular, Info-ZIP makes no claim as to the validity of
X   the fourth copyright notice, which did not appear in any of the original
X   source code in question.  We do NOT, however, dispute the fact that Mr.
X   Mascott made contributions to unzip--in fact, he was apparently responsi-
X   ble for the original port to Unix on which Info-ZIP UnZip is based.  As
X   an author, his wishes should be honored, regardless of any copyrights.
X
X   Regarding the original copyright by Mr. Smith:  Info-ZIP has attempted to
X   contact Mr. Smith at the BBS formerly listed in the usage screen, in order
X   to comply with his first stipulation; no response was ever received, and
X   as of early 1992 the number no longer exists (hence was removed from the
X   usage screen lest it be reassigned to someone else by the phone company).
X   Since the current incarnation of UnZip can be considered "our own"--it
X   bears very little resemblance to his original program, in either content
X   or size :-) --and since we freely distribute the source code, we feel that
X   we are within the bounds of his third stipulation.  In any case, Info-ZIP
X   has acted in good faith, and we hope we are not overstepping our authority.
X
X   Info-ZIP would *like* UnZip to be distributed with minimal restrictions,
X   and to that end, the authors are working to rewrite portions of the code
X   where time permits.  This is a slow business, however, and it is not a
X   primary concern for most of us.  So don't hold your breath. :-)

X.SH NAME
Xzipinfo - list detailed information about a ZIP archive file
X.SH SYNOPSIS
Xzipinfo [-1lv] file[.zip] [filespec...]
X.SH ARGUMENTS
X.in +12
X.ti -12
Xfile[.zip]  Path of the ZIP archive.  The suffix ``.zip'' is applied
Xif the file specified does not exist.  Note that
Xself-extracting ZIP files are supported; just specify
Xthe ``.exe'' suffix yourself.
X.sp 1
X.ti -12
X[filespec]  An optional list of archive members to be processed.
XExpressions may be used to match multiple members; be sure to quote
Xexpressions that contain characters interpreted by the UNIX shell. See
XPATTERN MATCHING (below) for more details.
X.SH OPTIONS
X.nf
X   -1  list filenames only, one per line (useful for pipes)
X   -l  list files in Unix "ls -l" format:  default
X   -v  list files in verbose, multi-page format
X.fi
X.SH DESCRIPTION
X.B ZipInfo
Xlists technical information about a ZIP archive, including information
Xfile access permissions, encryption status, type of compression, version
Xand operating system of compressing program, and the like.  The default
Xoption is to list files in the following format:
X.sp 1
X.nf
X.ti -5
X-rw-rwl---  1.5 unx    2802 t-     538 defX 11-Aug-91 13:48 perms.2660
X.fi
X.sp 1
XThe last three fields are clearly the modification date and time of
Xthe file, and its name.  The case of the filename is respected; thus
Xfiles which come from MS-DOS are always capitalized.  If the file was
Xzipped with a stored directory name, that is also displayed as part of
Xthe filename.
X.sp 1
XThe second and third fields indicate that the file was zipped under
XUnix with version 1.5 of zip (not available, so don't ask--this is
Xjust an example).  Since it comes from Unix, the file permissions at
Xthe beginning of the line are printed in Unix format.  The uncompressed
Xfile-size (2802 in this example) is the fourth field, and the compressed
Xfile-size is the sixth (538).
X.sp 1
XThe fifth field consists of two characters, either of which may take
Xon several values.  The first character may be either `t' or `b', indicating
Xthat zip believes the file to be text or binary, respectively; but if the
Xfile is encrypted,
X.B ZipInfo
Xnotes this fact by capitalizing the character (`T' or `B').  The second
Xcharacter may also take on four values, depending on whether there is
Xan extended local header and/or an ``extra field'' associated with the
Xfile (explained in PKWare's APPNOTE.TXT).  If neither exists, the character
Xwill be a hyphen (`-'); if there is an extended local header but no extra
Xfield, `l'; if the reverse, `x'; and if both exist, `X'.  Thus the
Xfile in this example is (apparently) a text file, is not encrypted, and
Xhas neither an extra field nor an extended local header associated with it.
XThe example below, on the other hand, is an encrypted binary file with an
Xextra field:
X.sp 1
X.nf
X.ti -5
XRWD,R,R     0.9 vms     168 Bx     165 shrk  9-Aug-91 19:15 perms.0644
X.fi
X.sp 1
XExtra fields are used by PKWare for authenticity verification (?) and
Xpossibly other purposes, and by an upcoming release of Info-ZIP's zip
Xfor VMS (to store file attributes).  This example presumably falls into
Xthe latter class, then.  Note that the file attributes are listed in
XVMS format.  Other possibilities for the host operating system are
XOS/2 with High Performance File System
X(HPFS), and DOS or OS/2 with File Allocation Table (FAT) file system, denoted
Xas follows:
X.sp 1
X.nf
X.ti -5
Xarc,hid,rdo,sys dos    4096 b-    2334 i4:2 14-Jul-91 12:58 EA DATA. SF
X.ti -5
Xarc,,rw,    1.0 os2    5358 Tl    1914 i4:3  4-Dec-91 11:33 longfilename.hpfs
X.fi
X.sp 1
XFile attributes in both of these cases are indicated in a DOS-like format,
Xwhere the file may or may not have its archive bit set; may be hidden or not;
Xmay be read-write or read-only; and may be a system file or not.  If the
Xattributes are too long, the version number of the encoding software is
Xomitted.  (The information is still available in the verbose listing,
Xhowever.)
X.sp 1
XFinally, the seventh field indicates
Xthe compression method and possible sub-method used.  There are six methods
Xknown at present:  storing (no compression), reducing, shrinking, imploding,
Xtokenizing, and deflating.  In addition, there are four levels of reducing
X(1 through 4); four types of imploding (4K or 8K sliding dictionary, and
X2 or 3 Shannon-Fano trees); and three levels of deflating (fast, normal,
Xmaximum compression).
X.B ZipInfo
Xrepresents these methods and their sub-methods as follows:  ``stor'';
X``re:1,'' ``re:2,'' etc.; ``shrk''; ``i4:2,'' ``i8:3,'' etc.; ``tokn'';
Xand ``defF,'' ``defN,'' and ``defX.''
X.sp 1
XThe verbose listing is self-explanatory.  It also lists file comments and
Xthe zipfile comment, if any.
X.SH PATTERN MATCHING
XAll archive members are listed unless a
X.B filespec
Xis provided to specify a subset of the archive members.
XThe
X.B filespec
Xis similar to an egrep expression, and may contain:
X.sp 1
X.in +8
X.ti -8
X*       matches a sequence of 0 or more characters
X.ti -8
X?       matches exactly 1 character
X.ti -8
X\\nnn    matches the character having octal code nnn
X.ti -8
X[...]   matches any single character found inside the brackets; ranges
Xare specified by a beginning character, a hyphen, and an ending
Xcharacter.  If a '!' follows the left bracket, then the range
Xof characters matched is complemented with respect to the ASCII
Xcharacter set.
X.SH TIPS
XThe author finds it convenient to set up an alias ``ii'' for
X.B ZipInfo
Xon systems which allow aliases, or else to set up a batch file ``ii.bat''
Xor to rename the executable to ``ii.exe'' on systems such as MS-DOS which
Xhave no provision for aliases.  The ``ii'' usage parallels the common
X``ll'' alias for long listings in Unix, and the similarity between the
Xoutputs of the two commands was intentional.
X.SH AUTHOR
XGreg Roelofs (also known as Cave Newt).
X.B ZipInfo
Xis partly based on
XS. H. Smith's unzip and contains pattern-matching code from Thom
XHenderson, but mostly it was written from scratch.

X     [filespec]  An optional list of archive members to  be  pro-
X                 cessed.  Expressions may be used to match multi-
X                 ple members; be sure to quote  expressions  that
X                 contain   characters  interpreted  by  the  UNIX
X                 shell. See PATTERN  MATCHING  (below)  for  more

X     encrypted, ZipInfo notes this fact by capitalizing the char-
X     acter  (`T'  or `B').  The second character may also take on
X     four values, depending on whether there is an extended local
X     header  and/or  an  ``extra field'' associated with the file
X     (explained in PKWare's APPNOTE.TXT).  If neither exists, the
X     character  will  be  a hyphen (`-'); if there is an extended
X     local header but no extra field, `l'; if the  reverse,  `x';
X     and  if  both  exist, `X'.  Thus the file in this example is
X     (apparently) a text file, is not encrypted, and has  neither
X     an  extra field nor an extended local header associated with
X     it.  The example below, on the other hand, is  an  encrypted
X     binary file with an extra field:

X
X     Extra fields are used by PKWare for  authenticity  verifica-
X     tion  (?)  and  possibly  other purposes, and by an upcoming
X     release of Info-ZIP's zip for  VMS  (to  store  file  attri-
X     butes).   This  example  presumably  falls  into  the latter
X     class, then.  Note that the file attributes  are  listed  in
X     VMS format.  Other possibilities for the host operating sys-
X     tem are OS/2 with High Performance File System  (HPFS),  and
X     DOS  or  OS/2  with File Allocation Table (FAT) file system,
X     denoted as follows:
X
Xarc,hid,rdo,sys dos    4096 b-    2334 i4:2 14-Jul-91 12:58 EA DATA. SF
Xarc,,rw,    1.0 os2    5358 Tl    1914 i4:3  4-Dec-91 11:33 longfilename.hpfs
X
X     File attributes in both of these cases are  indicated  in  a
X     DOS-like  format,  where  the  file  may or may not have its
X     archive bit set; may be hidden or not; may be read-write  or
X     read-only;  and  may be a system file or not.  If the attri-
X     butes are too long,  the  version  number  of  the  encoding
X     software is omitted.  (The information is still available in
X     the verbose listing, however.)
X
X     Finally, the seventh field indicates the compression  method
X     and  possible  sub-method used.  There are six methods known
X     at present:  storing (no compression), reducing,  shrinking,
X     imploding,  tokenizing,  and  deflating.  In addition, there
X     are four levels of reducing (1 through  4);  four  types  of
X     imploding  (4K or 8K sliding dictionary, and 2 or 3 Shannon-
X     Fano trees); and three levels of  deflating  (fast,  normal,
X     maximum  compression).  ZipInfo represents these methods and
X     their sub-methods as follows:  ``stor''; ``re:1,'' ``re:2,''
X     etc.;  ``shrk'';  ``i4:2,''  ``i8:3,''  etc.;  ``tokn''; and
X     ``defF,'' ``defN,'' and ``defX.''
X
X     The verbose listing is self-explanatory.  It also lists file
X     comments and the zipfile comment, if any.

XPATTERN MATCHING
X     All archive members are listed unless a filespec is provided
X     to specify a subset of the archive members.  The filespec is
X     similar to an egrep expression, and may contain:
X
X     *       matches a sequence of 0 or more characters
X     ?       matches exactly 1 character
X     \nnn    matches the character having octal code nnn
X     [...]   matches any single character found inside the brack-
X             ets;  ranges are specified by a beginning character,
X             a hyphen, and an ending character.  If a '!' follows
X             the  left  bracket,  then  the  range  of characters
X             matched is complemented with respect  to  the  ASCII
X             character set.
X
XTIPS
X     The author finds it convenient to set up an alias ``ii'' for
X     ZipInfo  on systems which allow aliases, or else to set up a
X     batch  file  ``ii.bat''  or  to  rename  the  executable  to
X     ``ii.exe'' on systems such as MS-DOS which have no provision
X     for aliases.  The ``ii'' usage parallels the  common  ``ll''
X     alias  for long listings in Unix, and the similarity between
X     the outputs of the two commands was intentional.

XAUTHOR
X     Greg Roelofs (also known as Cave Newt).  ZipInfo  is  partly
X     based  on  S. H. Smith's unzip and contains pattern-matching
X     code from Thom Henderson, but mostly  it  was  written  from
X     scratch.
