        !            54: .I zip
        !            55: is a compression and file packaging utility for Unix, VMS, MSDOS,
        !            56: OS/2, Windows NT, Minix, Atari and Macintosh.  It is analogous to a
        !            57: combination of tar and compress and is compatible with PKZIP (Phil
        !            58: Katz ZIP) for MSDOS systems.
        !            59: .PP
        !            60: There is a companion to
        !            61: .I zip
        !            62: called
        !            63: .I unzip
        !            64: (of course) which you should be able
        !            65: to find the same place you got
        !            66: .I zip.  zip
        !            67: and
        !            68: .I unzip
        !            69: can work with files
        !            70: produced by PKZIP under MSDOS, and PKZIP and PKUNZIP can work with files
        !            71: produced by
        !            72: .I zip.
        !            73: .PP
        !            74: .I zip
        !            75: version 1.9 is compatible with pkzip 1.93a.
        !            76: Note that pkunzip 1.10 cannot extract files produced by pkzip 1.93a
        !            77: or zip 1.9. You must use pkunzip 1.93a or unzip 5.0 to extract them.
        !            78: .PP
        !            79: For a brief help on
        !            80: .I zip
        !            81: and
        !            82: .I unzip,
        !            83: run each without specifying any parameters on the command line.
        !            84: .PP
        !            85: .I zip
        !            86: puts one or more compressed files into a single "zip file" along with
        !            87: information about the files, including the name, path if requested, date
        !            88: and time last modified, protection, and check information to verify the
        !            89: fidelity of each entry.
        !            90: .I zip
        !            91: can also be used as a filter, compressing standard input to standard output.
        !            92: .I zip
        !            93: can pack an entire directory structure in a
        !            94: zip file with a single command.  Compression ratios of 2:1 to 3:1 are
        !            95: common for text files.
        !            96: .I zip
        !            97: has one compression method (deflation) and can also store files without
        !            98: compression. It automatically chooses the better of the two for each file
        !            99: to be compressed.
        !           100: .PP
        !           101: .I zip
        !           102: is useful for packaging a set of files to send to someone or for distribution;
        !           103: for archiving or backing up files; and for saving disk space by temporarily
        !           104: compressing unused files or directories.
        !           105: .SH "HOW TO USE ZIP"
        !           106: The simplest use of
        !           107: .I zip
        !           108: is as follows:
        !           109: .PP
        !           110: .ti +5n
        !           111: zip stuff *
        !           112: .PP
        !           113: This will create the file "stuff.zip" (assuming it does not exist) and put
        !           114: all the files in the current directory in stuff.zip in a compressed form.
        !           115: The .zip suffix is added automatically, unless that file name given contains
        !           116: a dot already.  This allows specifying suffixes other than ".zip".
        !           117: .PP
        !           118: Because of the way the shell does filename substitution, files that start
        !           119: with a "." are not included.  To include those as well, you can:
        !           120: .PP
        !           121: .ti +5n
        !           122: zip stuff .* *
        !           123: .PP
        !           124: Even this will not include any subdirectories that are in the current
        !           125: directory.  To zip up an entire directory, the command:
        !           126: .PP
        !           127: .ti +5n
        !           128: zip -r foo foo
        !           129: .PP
        !           130: will create the file "foo.zip" containing all the files and directories in
        !           131: the directory "foo" that is in the current directory. (The first "foo" denotes
        !           132: the zip file, the second one denotes the directory.)  The "r" option means
        !           133: recurse through the directory structure.  In this case, all the
        !           134: files and directories in foo are zipped, including the ones that start with
        !           135: a ".", since the recursion does not use the shell's file-name substitution.
        !           136: You should not use -r with the name ".*", since that matches ".." which will
        !           137: attempt to zip up the parent directory--probably not what was intended.
        !           138: .PP
        !           139: You may want to make a zip file that contains the files in foo, but not record
        !           140: the directory name, foo.  You can use the -j (junk path) option to leave off
        !           141: the path:
        !           142: .PP
        !           143: .ti +5n
        !           144: zip -j foo foo/*
        !           145: .PP
        !           146: The -y option (only under Unix) will store symbolic links as such in the
        !           147: zip file, instead of compressing and storing the file referred to in the link.
        !           148: .PP
        !           149: You might be zipping to save disk space, in which case you could:
        !           150: .PP
        !           151: .ti +5n
        !           152: zip -rm foo foo
        !           153: .PP
        !           154: where the "m" option means "move".  This will delete foo and its contents
        !           155: after making foo.zip.  No deletions will be done until the zip has completed
        !           156: with no errors.  This option is obviously more dangerous and should be
        !           157: used with care.
        !           158: .PP
        !           159: If the zip file already exists, these commands will replace existing or add
        !           160: new entries to the zip file.  For example, if you were really short on disk
        !           161: space, you might not have enough room simultaneously to hold the directory
        !           162: foo and the compressed foo.zip.  In this case, you could do it in steps.  If
        !           163: foo contained the subdirectories tom, dick, and harry, then you could:
        !           164: .PP
        !           165: .ti +5n
        !           166: zip -rm foo foo/tom
        !           167: .ti +5n
        !           168: zip -rm foo foo/dick
        !           169: .ti +5n
        !           170: zip -rm foo foo/harry
        !           171: .PP
        !           172: where the first command would create foo.zip, and the next two would add to
        !           173: it.  At the completion of each zip command, the directory just zipped would
        !           174: be deleted, making room in which the next
        !           175: .I zip
        !           176: command could work.
        !           177: .PP
        !           178: .I zip
        !           179: will also accept a single dash ("-") as the zip file name, in which case it
        !           180: will write the zip file to stdout, allowing the output to be piped to another
        !           181: program. For example:
        !           182: .PP
        !           183: .ti +5n
        !           184: zip -r - . | dd of=/dev/nrst0 obs=16k
        !           185: .PP
        !           186: would write the zip output directly to a tape with the specified block size
        !           187: for the purpose of backing up the current directory.
        !           188: .PP
        !           189: .I zip
        !           190: also accepts a single dash ("-") as the name of a file to be compressed, in
        !           191: which case it will read the zip file from stdin, allowing zip to take
        !           192: input from another program. For example:
        !           193: .PP
        !           194: .ti +5n
        !           195: tar cf - . | zip backup -
        !           196: .PP
        !           197: would compress the output of the tar command for the purpose of backing up
        !           198: the current directory. This generally produces better compression than
        !           199: the previous example using the -r option, because
        !           200: .I zip
        !           201: can take advantage of redundancy between files. The backup can be restored
        !           202: using the command
        !           203: .PP
        !           204: .ti +5n
        !           205: unzip -p backup | tar xf -
        !           206: .PP
        !           207: When no zip file name is given and stdout is not a terminal,
        !           208: .I zip
        !           209: acts as a filter, compressing standard input to standard output.
        !           210: For example,
        !           211: .PP
        !           212: .ti +5n
        !           213: tar cf - . | zip | dd of=/dev/nrst0
        !           214: .PP
        !           215: is equivalent to
        !           216: .PP
        !           217: .ti +5n
        !           218: tar cf - . | zip - - | dd of=/dev/nrst0
        !           219: .PP
        !           220: Zip archives created in this manner can be extracted with the program
        !           221: .I funzip
        !           222: which is provided in the
        !           223: .I unzip
        !           224: package. For example,
        !           225: .PP
        !           226: .ti +5n
        !           227:    dd if=/dev/nrst0 | funzip | tar xvf -
        !           228: .SH "MODIFYING EXISTING ZIP FILES"
        !           229: When given the name of an existing zip file with the above commands,
        !           230: .I zip
        !           231: will replace identically named entries in the

        !           233: file or add entries for

        !           243: unchanged from before.
        !           244: .PP
        !           245: When changing an existing zip file,
        !           246: .I zip
        !           247: will write a temporary file with
        !           248: the new contents, and only replace the old one when the zip has completed
        !           249: with no errors. You can use
        !           250: the -b option to specify a different path (usually a different device) to
        !           251: put the temporary file in.  For example:
        !           252: .PP
        !           253: .ti +5n
        !           254: zip -b /tmp stuff *
        !           255: .PP
        !           256: will put the temporary zip file and the temporary compression files in the
        !           257: directory "/tmp", copying over stuff.zip in the current directory when
        !           258: done.
        !           259: .PP
        !           260: If you are only adding entries to a zip file, not replacing, and the
        !           261: -g option is given, then
        !           262: .I zip
        !           263: grows (appends to) the file instead of copying it.  The danger of this is that
        !           264: if the operation fails, the original zip file is corrupted and lost.
        !           265: .PP
        !           266: There are two other ways to change or add entries in a zip file that are
        !           267: restrictions of simple addition or replacement.  The first is -u (update)
        !           268: which will add new entries to the zip file as before but will replace
        !           269: existing entries only if the modified date of the file is more recent than
        !           270: the date recorded for that name in the zip file.  For example:
        !           271: .PP
        !           272: .ti +5n
        !           273: zip -u stuff *
        !           274: .PP
        !           275: will add any new files in the current directory, and update any changed files
        !           276: in the zip file stuff.zip.  Note that
        !           277: .I zip
        !           278: will not try to pack stuff.zip into
        !           279: itself when you do this. 
        !           280: .I zip
        !           281: will always exclude the zip file from the files on which to be operated.
        !           282: .PP
        !           283: The second restriction is -f (freshen) which, like update, will only replace
        !           284: entries with newer files; unlike update, will not add files that are not
        !           285: already in the zip file.  For this option, you may want to simply freshen all
        !           286: of the files that are in the specified zip file.  To do this you would simply:
        !           287: .PP
        !           288: .ti +5n
        !           289: zip -f foo
        !           290: .PP
        !           291: Note that the -f option with no arguments freshens all the entries in the
        !           292: zip file.  The same is true of -u, and hence "zip -u foo" and "zip -f foo"
        !           293: both do the same thing.
        !           294: .PP
        !           295: This command should
        !           296: be run from the same directory from which the original zip command was run,
        !           297: since paths stored in zip files are always relative.
        !           298: .PP
        !           299: Another restriction that can be used with adding, updating, or freshening is
        !           300: -t (time), which will not operate on files modified earlier than the specified
        !           301: date.  For example:
        !           302: .PP
        !           303: .ti +5n
        !           304: zip -rt 120791 infamy foo
        !           305: .PP
        !           306: will add all the files in foo and its subdirectories that were last modified
        !           307: on December 7, 1991, or later to the zip file infamy.zip.
        !           308: .PP
        !           309: Also, files can be explicitly excluded using the -x option:
        !           310: .PP
        !           311: .ti +5n
        !           312: zip -r foo foo -x \\*.o
        !           313: .PP
        !           314: which will zip up the contents of foo into foo.zip but exclude all the
        !           315: files that end in ".o".  Here the backslash causes
        !           316: .I zip
        !           317: to match file names
        !           318: that were found when foo was searched.
        !           319: .PP
        !           320: The last operation is -d (delete) which will remove entries from a zip file.
        !           321: An example might be:
        !           322: .PP
        !           323: .ti +5n
        !           324: zip -d foo foo/tom/junk foo/harry/\\* \\*.o
        !           325: .PP
        !           326: which will remove the entry foo/tom/junk, all of the files that start with
        !           327: "foo/harry/", and all of the files that end with ".o" (in any path).  Note
        !           328: that once again, the shell expansion has been inhibited with backslashes, so
        !           329: that
        !           330: .I zip
        !           331: can see the asterisks.  
        !           332: .I zip
        !           333: can then match on the contents of the zip
        !           334: file instead of the contents of the current directory.
        !           335: .PP
        !           336: Under MSDOS, -d is case sensitive when it matches names in the zip file.
        !           337: This allows deleting names that were zipped on other systems, but requires
        !           338: that the names be entered in upper case if they were zipped on an MSDOS
        !           339: system, so that the names can be found in the zip file and deleted.
        !           340: .SH "MORE OPTIONS"
        !           341: As mentioned before,
        !           342: .I zip
        !           343: will use the best of two methods: deflate or store.
        !           344: .PP
        !           345: The option -0 will force
        !           346: .I zip
        !           347: to use store on all files. For example:
        !           348: .PP
        !           349: .ti +5n
        !           350: zip -r0 foo foo
        !           351: .PP
        !           352: will zip up the directory foo into foo.zip using only store.
        !           353: .PP
        !           354: The speed of deflation can also be controlled with options -1 (fastest
        !           355: method but less compression) to -9 (best compression but slower). The
        !           356: default value is -5. For example:
        !           357: .PP
        !           358: .ti +5n
        !           359: zip -r8 foo foo
        !           360: .PP
        !           361: In nearly all cases, a file that is already compressed cannot be compressed
        !           362: further by
        !           363: .I zip,
        !           364: or if it can, the effect is minimal.  The -n option prevents
        !           365: .I zip
        !           366: from trying to compress files that have the given suffixes.
        !           367: Such files are simply stored (0% compression) in the output zip file,
        !           368: so that
        !           369: .I zip
        !           370: doesn't waste its time trying to compress them.
        !           371: The suffixes are separated by
        !           372: either colons or semicolons.  For example:
        !           373: .PP
        !           374: .ti +5n
        !           375: zip -rn ".Z:.zip:.tiff:.gif:.snd"  foo foo
        !           376: .PP
        !           377: will put everything in foo into foo.zip, but will store any files that end
        !           378: in .Z, .zip, .tiff, .gif, or .snd without trying to compress them.  (Image
        !           379: and sound files often have their own specialized compression methods.)
        !           380: The default suffix list is ".Z:.zip;.zoo:.arc:.lzh:.arj".
        !           381: The environment variable ZIPOPT can be used to change this default. For
        !           382: example under Unix with csh:
        !           383: .PP
        !           384: .ti +5n
        !           385: setenv ZIPOPT "-n .gif:.zip"
        !           386: .PP
        !           387: The variable ZIPOPT can be used for any option and can include several
        !           388: options.
        !           389: .PP
        !           390: Under Unix and under OS/2 (if files from an HPFS are stored),
        !           391: .I zip
        !           392: will store the full path (relative to the current path) and name of the
        !           393: file (or just the name if -j is specified) in the zip file along with the
        !           394: Unix attributes, and it will mark
        !           395: the entry as made under Unix.  If the zip file is intended for PKUNZIP under
        !           396: MSDOS, then the -k (Katz) option should be used to attempt to convert the
        !           397: names and paths to conform to MSDOS, store only the MSDOS attribute (just
        !           398: the user write attribute from Unix), and mark the entry as made under MSDOS
        !           399: (even though it wasn't).
        !           400: .PP
        !           401: The -o (older) option will set the "last modified" time of the zip file to
        !           402: the latest "last modified" time of the entries in the zip file.  This can
        !           403: be used without any other operations, if desired.  For example:
        !           404: .PP
        !           405: .ti +5n
        !           406: zip -o foo
        !           407: .PP
        !           408: will change the last modified time of foo.zip to the latest time of the
        !           409: entries in foo.zip.
        !           410: .PP
        !           411: The -e and -c options operate on all files updated or added to the zip file.
        !           412: Encryption (-e) will prompt for a password on the terminal and will
        !           413: not echo the password as it is typed (if stderr is not a TTY, zip will exit
        !           414: with an error).  New zip entries will be encrypted using that password.  For
        !           415: added peace of mind, you can use -ee, which will prompt for the password
        !           416: twice, checking that the two are the same before using it. The encryption
        !           417: code is distributed separately, so the -e option may not be available
        !           418: in your version.
        !           419: .PP
        !           420: One-line comments can be added for each file with the -c option.  The zip
        !           421: file operations (adding or updating) will be done first, and you will then be
        !           422: prompted for a one-line comment for each file.  You can then enter the comment
        !           423: followed by return, or just return for no comment.
        !           424: .PP
        !           425: The -z option will prompt you for a multi-line comment for the entire zip
        !           426: file.  This option can be used by itself, or in combination with other
        !           427: options.  The comment is ended by a line containing just a period, or an end
        !           428: of file condition (^D on Unix, ^Z on MSDOS, OS/2, and VAX/VMS).
        !           429: Since -z reads the
        !           430: lines from stdin, you can simply take the comment from a file:
        !           431: .PP
        !           432: .ti +5n
        !           433: zip -z foo < foowhat
        !           434: .PP
        !           435: The -q (quiet) option eliminates the informational messages and comment prompts
        !           436: while
        !           437: .I zip
        !           438: is operating.  This might be used in shell scripts, for example, or if the
        !           439: zip operation is being performed as a background task ("zip -q foo *.c &").
        !           440: .PP
        !           441: .I zip
        !           442: can take a list of file names to operate on from stdin using the -@ option.
        !           443: In Unix, this option can be used with the find command to extend greatly
        !           444: the functionality of
        !           445: .I zip.
        !           446: For example, to zip up all the C source files in the current directory and
        !           447: its subdirectories, you can:
        !           448: .PP
        !           449: .ti +5n
        !           450: find . -type f -name "*.[ch]" -print | zip source -@
        !           451: .PP
        !           452: Note that the pattern must be quoted to keep the shell from expanding it.
        !           453: .PP
        !           454: Under VMS only, the -w option will append the version number of the files to
        !           455: the name and zip up multiple versions of files.  Without -w,
        !           456: .I zip
        !           457: will only use the most recent version of the specified file(s).
        !           458: .PP
        !           459: The -l option translates the Unix end-of-line character LF into the
        !           460: MSDOS convention CR LF. This option should not be used on binary files.
        !           461: This option can be used on Unix if the zip file is intended for PKUNZIP
        !           462: under MSDOS. If the input files already contain CR LF, this option adds
        !           463: an extra CR. This ensure that "unzip -a" on Unix will get back an exact
        !           464: copy of the original file, to undo the effect of "zip -l".
        !           465: .PP
        !           466: If
        !           467: .I zip

        !           534: .SH BUGS
        !           535: WARNING: zip files produced by zip 1.9 must not be
        !           536: *updated* by zip 1.0 or pkzip 1.10 or pkzip 1.93a, if they contain
        !           537: encrypted members, or if they have been produced in a pipe or on a non
        !           538: seekable device. The old versions of zip or pkzip would destroy the
        !           539: zip structure. The old versions can list the contents of the zip file
        !           540: but cannot extract it anyway (because of the new compression algorithm).
        !           541: If you do not use encryption and use regular disk files, you do
        !           542: not have to care about this problem.
        !           543: .PP
        !           544: zip 1.9 is compatible with pkzip 1.93a, except when two features
        !           545: are used: encryption or zip file created in a pipe or on a non
        !           546: seekable device. pkzip versions above 2.0 will support such files, and
        !           547: unzip 5.0 already supports them.
        !           548: .PP
        !           549: Without -y, when zip must compress a symbolic link to an non existing file,
        !           550: it only displays a warning "name not matched". A better warnign should be
        !           551: given.
        !           552: .PP
        !           553: The option -e also forces -o (make zipfile as old as latest entry). This
        !           554: is used to make brute force attacks on the password harder.
        !           555: .PP
        !           556: Under VMS, not all of the odd file formats are treated properly.  Only
        !           557: zip files of format stream-LF and fixed length 512 are expected to work
        !           558: with zip.  Others can be converted using Rahul Dhesi's BILF program.
        !           559: This version of zip does handle some of the conversion internally.
        !           560: When using Kermit to transfer zip files from Vax to MSDOS, type "set
        !           561: file type block" on the Vax.  When transfering from MSDOS to Vax, type
        !           562: "set file type fixed" on the Vax.  In both cases, type "set file type
        !           563: binary" on MSDOS.
        !           564: .PP
        !           565: Under VMS, zip hangs for file specification that uses DECnet syntax (foo::*.*).
        !           566: .PP
        !           567: Under OS/2, the amount of External Attributes displayed by DIR is (for
        !           568: compatibility) the amount returned by the 16-bit version of
        !           569: DosQueryPathInfo(). Otherwise OS/2 1.3 and 2.0 would report different
        !           570: EA sizes when DIRing a file.
        !           571: However, the structure layout returned by the 32-bit DosQueryPathInfo()
        !           572: is a bit different, it uses extra padding bytes and link pointers (it's
        !           573: a linked list) to have all fields on 4-byte boundaries for portability
        !           574: to future RISC OS/2 versions. Therefore the value reported by ZIP
        !           575: (which uses this 32-bit-mode size) differs from that reported by DIR.
        !           576: ZIP stores the 32-bit format for portability, even the 16-bit
        !           577: MS-C-compiled version running on OS/2 1.3, so even this one shows the
        !           578: 32-bit-mode size.
