This is version 2.0b3 of macutil (22-OCT-1992).
|
||||
|
||||
This package contains the following utilities:
|
||||
macunpack
|
||||
hexbin
|
||||
macsave
|
||||
macstream
|
||||
binhex
|
||||
tomac
|
||||
frommac
|
||||
|
||||
Requirements:
|
||||
a. Of course a C compiler.
|
||||
b. A 32-bit machine with large memory (or at least the ability to 'malloc'
|
||||
large chunks of memory). For reasons of efficiency and simplicity the
|
||||
programs work 'in-core', also many files are first read in core.
|
||||
If somebody can take the trouble to do it differently, go ahead!
|
||||
There are also probably in a number of places implicit assumptions that
|
||||
an int is 32 bits. If you encounter such occurrences feel free to
|
||||
notify me.
|
||||
c. A Unix (tm) machine, or something very close. There are probably quite
|
||||
a lot of Unix dependencies. Also here, if you have replacements, feel
|
||||
free to send comments.
|
||||
d. This version normally uses the 'mkdir' system call available on BSD Unix
|
||||
and some versions of SysV Unix. You can change that, see the makefile for
|
||||
details.
|
||||
|
||||
File name translation:
|
||||
|
||||
The programs use a table driven program to do Mac filename -> Unix filename
|
||||
translation. When compiled without further changes the translation is as
|
||||
follows:
|
||||
Printable ASCII characters except space and slash are not changed.
|
||||
Slash and space are changed to underscore, as are all characters that
|
||||
do not fall in the following group.
|
||||
Accented letters are translated to their unaccented counterparts.
|
||||
If your system supports the Latin-1 character set, you can change this
|
||||
translation scheme by specifying '-DLATIN1' for the 'CF' macro in the
|
||||
makefile. This will translate all accented letters (and some symbols)
|
||||
to their Latin-1 counterpart. This feature is untested (I do not have
|
||||
access to systems that cater for Latin-1), so use with care.
|
||||
Future revisions of the program will have user settable conversions.
|
||||
|
||||
Another feature of filename translation is that when the -DNODOT flag is
|
||||
specified in the CF macro an initial period will be translated to underscore.
|
||||
|
||||
MacBinary stream:
|
||||
|
||||
Most programs allow MacBinary streams as either input or output. A
|
||||
MacBinary stream is a series of files in MacBinary format pasted
|
||||
together. Embedded within a MacBinary stream can be information about
|
||||
folders. So a MacBinary stream can contain all information about a
|
||||
folder and its constituents.
|
||||
|
||||
Appleshare support:
|
||||
|
||||
Optionally the package can be compiled for systems that support the sharing
|
||||
of Unix and Mac filesystems. The package supports AUFS (AppleTalk Unix File
|
||||
Server) from CAP (Columbia AppleTalk Package) and AppleDouble (from Apple).
|
||||
It will not support both at the same time. Moreover this support requires
|
||||
the existence of the 'mkdir' system call. And finally, as implemented it
|
||||
probably will work on big-endian BSD compatible systems. If you have a SysV
|
||||
system with restricted filename lengths you can get problems. I do not know
|
||||
also whether the structures are stored native or Apple-wise on little-endian
|
||||
systems. And also, I did not test it fully; having no access to either AUFS
|
||||
or AppleDouble systems.
|
||||

||||
Acknowledgements:
|
||||
a. Macunpack is for a large part based on the utilities 'unpit' and 'unsit'
|
||||
written by:
|
||||
Allan G. Weber
|
||||
weber%brand.usc.edu@oberon.usc.edu
|
||||
(wondering whether that is still valid!). I combined the two into a
|
||||
single program and did a lot of modification. For information on the
|
||||
originals, see the files README.unpit and README.unsit.
|
||||
b. The crc-calculating routines are based on a routine originally written by:
|
||||
Mark G. Mendel
|
||||
UUCP: ihnp4!umn-cs!hyper!mark
|
||||
(this will not work anymore for sure!). Also here I modified the stuff
|
||||
and expanded it, see the files README.crc and README.crc.orig.
|
||||
c. LZW-decompression is taken from the sources of compress that are floating
|
||||
around. Probably I did not use the most efficient version, but this
|
||||
program was written to get it done. The version I based it on (4.0) is
|
||||
authored by:
|
||||
Steve Davies (decvax!vax135!petsd!peora!srd)
|
||||
Jim McKie (decvax!mcvax!jim) (Hi Jim!)

||||
Ken Turkowski (decvax!decwrl!turtlevax!ken)

||||

|
||||
I am sure those e-mail addresses also will not work!
|
||||
d. Optional AUFS support comes from information supplied by:
|
||||
Casper H.S. Dik

||||

||||

||||

phone: +31205922022
|
||||
email: casper@fwi.uva.nl
|
||||
This is an e-mail address that will workm but the address and phone
|
||||
number ar no longer valid.
|
||||
See the makefile.
|
||||
Some caveats are applicable:
|
||||
1. I did not fully test it (we do not use it). But the unpacking
|
||||
appears to be correct. Anyhow, as the people who initially compile
|
||||
it and use it will be system administrators I am confident they are
|
||||
able to locate bugs! (What if an archive contains a Macfile with
|
||||
the name .finderinfo or .resource? I have had two inputs for AUFS
|
||||
support [I took Caspers; his came first], but both do not deal with
|
||||
that. Does CAP deal with it?) Also I have no idea whether this
|
||||
version supports it under SysV, so beware.
|
||||
2. From one of the README's supplied by Casper:
|
||||
Files will not appear in an active folder, because Aufs doesn't like
|
||||
people working behind it's back.
|
||||
Simply opening and closing the folder will suffice.
|
||||
Appears to be the same problem as when you are unpacking or in some
|
||||
other way creating files in a folder open to multifinder. I have seen
|
||||
bundle bits disappear this way. So if after unpacking you see the
|
||||
generic icon; check whether a different icon should appear and check
|
||||
the bundle bit.
|
||||
The desktop isn't updated, but that doesn't seem to matter.
|
||||
I dunno, not using it.
|
||||
e. Man pages are now supplied. The base was provided by:
|
||||
Douglas Siebert
|
||||
ISCA
|
||||
dsiebert@icaen.uiowa.edu
|
||||
f. Because of some problems the Uncompactor has been rewritten, it is now
|
||||
based on sources from the dearchiver unzip (of PC fame). Apparently the
|
||||
base code is by:
|
||||
Samuel H. Smith
|
||||
I have no further address available, but as soon as I find a better
|
||||
attribution, I will include it.
|
||||
g. UnstuffIt's LZAH code comes from lharc (also of PC fame) by:
|
||||
Haruhiko Okumura,
|
||||
Haruyasu Yoshizaki,
|
||||
Yooichi Tagawa.
|
||||
h. Zoom's code comes from information supplied by Jon W{tte
|
||||
(d88-jwa@nada.kth.se). The Zoo decompressor is based on the routine
|
||||
written by Rahul Dhesi (dhesi@cirrus.COM). This again is based on
|
||||
code by Haruhiko Okumura. See also the file README.zoom.
|
||||
i. MacLHa's decompressors are identical to the ones mentioned in g and h.
|
||||
j. Most of hexbin's code is based on code written/modified by:
|
||||
Dave Johnson, Brown University Computer Science
|
||||
Darin Adler, TMQ Software
|
||||
Jim Budler, amdcad!jimb
|
||||
Dan LaLiberte, liberte@uiucdcs
|
||||
ahm (?)
|
||||
Jeff Meyer, John Fluke Company
|
||||
Guido van Rossum, guido@cwi.nl (Hi!)
|
||||
(most of the e-mail addresses will not work, the affiliation may also
|
||||
be incorrect by now.) See also the file README.hexbin.
|
||||
k. The dl code in hexbin comes is based on the original distribution of
|
||||
SUMacC.
|
||||
l. The mu code in hexbin is a slight modification of the hcx code (the
|
||||
compressions are identical).
|
||||
m. The MW code for StuffIt is loosely based on code by Daniel H. Bernstein
|
||||
(brnstnd@acf10.nyu.edu).
|
||||
n. Tomac and frommac are loosely based on the original macput and macget
|
||||
by (the e-mail address will not work anymore):

|
||||
Macunpack will unpack PackIt, StuffIt, Diamond, Compactor/Compact Pro, most
|
||||
StuffItClassic/StuffItDeluxe, and all Zoom and LHarc/MacLHa archives, and
|
||||
archives created by later versions of DiskDoubler.
|
||||
Also it will decode files created by BinHex5.0, MacBinary, UMCP,
|
||||
Compress It, ShrinkToFit, MacCompress, DiskDoubler and AutoDoubler.
|
||||
|
||||
(PackIt, StuffIt, Diamond, Compactor, Compact/Pro, Zoom and LHarc/MacLHa are
|
||||
archivers written by respectively: Harry R. Chesley, Raymond Lau, Denis Sersa,
|
||||
Bill Goodman, Jon W{tte* and Kazuaki Ishizaki. BinHex 5.0, MacBinary and
|
||||
UMCP are by respectively: Yves Lempereur, Gregory J. Smith, Information
|
||||
Electronics. ShrinkToFit is by Roy T. Hashimoto, Compress It by Jerry
|
||||
Whitnell, and MacCompress, DiskDoubler and AutoDoubler are all by
|
||||
Lloyd Chambers.)
|
||||
|
||||
* from his signature:
|
||||
Jon W{tte - Yes, that's a brace - Damn Swede.
|
||||
Actually it is an a with two dots above; some (German inclined) people
|
||||
refer to it (incorrectly) as a-umlaut.
|
||||
|
||||
It does not deal with:
|
||||
a. Password protected archives.
|
||||
b. Multi-segment archives.
|
||||
c. Plugin methods for Zoom.
|
||||
d. MacLHa archives not packed in MacBinary mode (the program deals very
|
||||
poorly with that!).
|
||||
|
||||
Background:
|
||||
There are millions of ways to pack files, and unfortunately, all have been
|
||||
implemented one way or the other. Below I will give some background
|
||||
information about the packing schemes used by the different programs
|
||||
mentioned above. But first some background about compression (I am no
|
||||
expert, more comprehensive information can be found in for instance:
|
||||
Tomothy Bell, Ian H. Witten and John G. Cleary, Modelling for Text
|
||||
Compression, ACM Computing Surveys, Vol 21, No 4, Dec 1989, pp 557-591).
|
||||
|
||||
Huffman encoding (also called Shannon-Fano coding or some other variation
|
||||
of the name). An encoding where the length of the code for the symbols
|
||||
depends on the frequency of the symbols. Frequent symbols have shorter
|
||||
codes than infrequent symbols. The normal method is to first scan the
|
||||
file to be compressed, and to assign codes when this is done (see for
|
||||
instance: D. E. Knuth, the Art of Computer Programming). Later methods
|
||||
have been designed to create the codes adaptively; for a survey see:
|
||||
Jeremy S. Vetter, Design and Analysis of Dynamic Huffman Codes, JACM,
|
||||
Vol 34, No 4, Oct 1987, pp 825-845.
|
||||
LZ77: The first of two Ziv-Lempel methods. Using a window of past encoded
|
||||
text, output consists of triples for each sequence of newly encoded
|
||||
symbols: a back pointer and length of past text to be repeated and the
|
||||
first symbol that is not part of that sequence. Later versions allowed
|
||||
deviation from the strict alternation of pointers and uncoded symbols
|
||||
(LZSS by Bell). Later Brent included Huffman coding of the pointers
|
||||
(LZH).
|
||||
LZ78: While LZ77 uses a window of already encoded text as a dictionary,
|
||||
LZ78 dynamically builds the dictionary. Here again pointers are strictly
|
||||
alternated with unencoded new symbols. Later Welch (LZW) managed to
|
||||
eliminate the output of unencoded symbols. This algorithm is about
|
||||
the same as the one independently invented by Miller and Wegman (MW).
|
||||
A problem with these two schemes is that they are patented. Thomas
|
||||
modified LZW to LZC (as used in the Unix compress command). While LZ78
|
||||
and LZW become static once the dictionary is full, LZC has possibilities
|
||||
to reset the dictionary. Many LZC variants are in use, depending on the
|
||||
size of memory available. They are distinguished by the maximum number
|
||||
of bits that are used in a code.
|
||||
A number of other schemes are proposed and occasionally used. The main
|
||||
advantage of the LZ type schemes is that (especially) decoding is fairly fast.
|
||||
|
||||
Programs background:
|
||||
|
||||
Plain programs:
|
||||
BinHex 5.0:
|
||||
Unlike what its name suggest this is not a true successor of BinHex 4.0.
|
||||
BinHex 5.0 takes the MacBinary form of a file and stores it in the data
|
||||
fork of the newly created file.
|
||||
Although BinHex 5.0 does not create BinHex 4.0 compatible files, StuffIt
|
||||
will give the creator type of BinHex 5.0 (BnHq) to its binhexed files,
|
||||
rather than the creator type of BinHex 4.0 (BNHQ). The program knows
|
||||
about that.
|
||||
MacBinary:
|
||||
As its name suggests, it does the same as BinHex 5.0.
|
||||
UMCP:
|
||||
Looks similar, but the file as stored by UMCP is not true MacBinary.
|
||||
Size fields are modified, the result is not padded to a multiple of 128,
|
||||
etc. Macunpack deals with all that, but until now is not able to
|
||||
correctly restore the finder flags of the original file. Also, UMCP
|
||||
created files have type "TEXT" and creator "ttxt", which can create a
|
||||
bit of confusion. Macunpack will recognize these files only if the
|
||||
creator has been modified to "UMcp".
|
||||
|
||||
Compressors:
|
||||
ShrinkToFit:
|
||||
This program uses a Huffman code to compress. It has an option (default
|
||||
checked for some reason), COMP, for which I do not yet know the
|
||||
meaning. Compressing more than a single file in a single run results
|
||||
in a failure for the second and subsequent files.
|
||||
Compress It:
|
||||
Also uses a Huffman code to compress.
|
||||
MacCompress:
|
||||
MacCompress has two modes of operation, the first mode is (confusingly)
|
||||
MacCompress, the second mode is (again confusingly) UnixCompress. In
|
||||
MacCompress mode both forks are compressed using the LZC algorithm.
|
||||
In UnixCompress mode only the data fork is compressed, and some shuffling
|
||||
of resources is performed. Upto now macunpack only deals with MacCompress
|
||||
mode. The LZC variant MacCompress uses depends on memory availability.
|
||||
12 bit to 16 bit LZC can be used.
|
||||
|
||||
Archivers:
|
||||
ArcMac:
|
||||
Nearly PC-Arc compatible. Arc knows 8 compression methods, I have seen
|
||||
all of them used by ArcMac, except the LZW techniques. Here they are:
|
||||
1: No compression, shorter header
|
||||
2: No compression
|
||||
3: (packing) Run length encoding
|
||||
4: (squeezing) RLE followed by Huffman encoding
|
||||
5: (crunching) LZW
|
||||
6: (crunching) RLE followed by LZW
|
||||
7: (crunching) as the previous but with a different hash function
|
||||
8: (crunching) RLE followed by 12-bit LZC
|
||||
9: (squashing) 13-bit LZC
|
||||
PackIt:
|
||||
When archiving a file PackIt either stores the file uncompressed or
|
||||
stores the file Huffman encoded. In the latter case both forks are
|
||||
encoded using the same Huffman tree.
|
||||
StuffIt and StuffIt Classic/Deluxe:
|
||||
These have the ability to use different methods for the two forks of a
|
||||
file. The following standard methods I do know about (the last three
|
||||
are only used by the Classic/Deluxe version 2.0 of StuffIt):
|
||||
0: No compression
|
||||
1: Run length encoding
|
||||
2: 14-bit LZC compression
|
||||
3: Huffman encoding
|
||||
5: LZAH: like LZH, but the Huffman coding used is adaptive
|
||||
6: A Huffman encoding using a fixed (built-in) Huffman tree
|
||||
8: A MW encoding
|
||||
Diamond:
|
||||
Uses a LZ77 like frontend plus a Fraenkel-Klein like backend (see
|
||||
Apostolico & Galil, Combinatorial Algorithms on Words, pages 169-183).
|
||||
Compactor/Compact Pro:
|
||||
Like StuffIt, different encodings are possible for data and resource fork.
|
||||
Only two possible methods are used:
|
||||
0: Run length encoding
|
||||
1: RLE followed by some form of LZH
|
||||
Zoom:
|
||||
Data and resource fork are compressed with the same method. The standard
|
||||
uses either no compression or some form of LZH
|
||||
MacLHa:
|
||||
Has two basic modes of operation, Mac mode and Normal mode. In Mac mode
|
||||
the file is archived in MacBinary form. In normal mode only the forks
|
||||
are archived. Normal mode should not be used (and can not be unpacked
|
||||
by macunpack) as all information about data fork size/resource fork size,
|
||||
type, creator etc. is lost. It knows quite a few methods, some are
|
||||
probably only used in older versions, the only methods I have seen used
|
||||
are -lh0-, -lh1- and -lh5-. Methods known by MacLHa:
|
||||
-lz4-: No compression
|
||||
-lz5-: LZSS
|
||||
-lzs-: LZSS, another variant
|
||||
-lh0-: No compression
|
||||
-lh1-: LZAH (see StuffIt)
|
||||
-lh2-: Another form of LZAH
|
||||
-lh3-: A form of LZH, different from the next two
|
||||
-lh4-: LZH with a 4096 byte buffer (as far as I can see the coding in
|
||||
MacLHa is wrong)
|
||||
-lh5-: LZH with a 8192 byte buffer
|
||||
DiskDoubler:
|
||||
The older version of DiskDoubler is compatible with MacCompress. It does
|
||||
not create archives, it only compresses files. The newer version (since
|
||||
3.0) does both archiving and compression. The older version uses LZC as
|
||||
its compression algorithm, the newer version knows a number of different
|
||||
compression algorithms. Many (all?) are algorithms used in other
|
||||
archivers. Probably this is done to simplify conversion from other formats
|
||||
to DiskDoubler format archives. I have seen actual DiskDoubler archives
|
||||
that used methods 0, 1 and 8:
|
||||
0: No compression
|
||||
1: LZC
|
||||
2: unknown
|
||||
3: RLE
|
||||
4: Huffman (or no compression)
|
||||
5: unknown
|
||||
6: unknown
|
||||
7: An improved form of LZSS
|
||||
8: Compactor/Compact Pro compatible RLE/LZH or RLE only
|
||||
9: unknown
|
||||
The DiskDoubler archive format contains many subtle twists that make it
|
||||
difficult to properly read the archive (or perhaps this is on purpose?).
|
||||
|
||||
Naming:
|
||||
Some people have complained about the name conflict with the unpack utility
|
||||
that is already available on Sys V boxes. I had forgotten it, so there
|
||||
really was a problem. The best way to solve it was to trash pack/unpack/pcat
|
||||
and replace it by compress/uncompress/zcat. Sure, man uses it; but man uses
|
||||
pcat, so you can retain pcat. If that was not an option you were able to feel
|
||||
free to rename the program. But finally I relented. It is now macunpack.
|
||||
|
||||
When you have problems unpacking an archive feel free to ask for information.
|
||||
I am especially keen when the program detects an unknown method. If you
|
||||
encounter such an archive, please, mail a 'binhexed' copy of the archive
|
||||
to me so that I can deal with it. Password protected archives are (as
|
||||
already stated) not implemented. I do not have much inclination to do that.
|
||||
Also I feel no inclination to do multi-segment archives.
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
Hexbin will de-hexify files created in BinHex 4.0 compatible format (hqx)
|
||||
but also the older format (dl, hex and hcx). Moreover it will uudecode
|
||||
files uuencoded by UUTool (the only program I know that does UU hexification
|
||||
of all Mac file information).
|
||||
|
||||
There are currently many programs that are able to create files in BinHex 4.0
|
||||
compatible format. There are however some slight differences, and most
|
||||
de-hexifiers are not able to deal with all the variations. This program is
|
||||
very simple minded. First it will intuit (based on the input) whether the
|
||||
file is in dl, hex, hcx or hqx format. Next it will de-hexify the file.
|
||||
When the format is hqx, it will check whether more files follow, and continue
|
||||
processing. So you can catenate multiple (hqx) hexified files together and
|
||||
feed them as a single file to hexbin. Also hexbin does not mind whether lines
|
||||
are separated by CR's, LF's or combinations of the two. Moreover, it will
|
||||
strip all leading, trailing and intermediate garbage introduced by mailers
|
||||
etc. Next, it does not mind if a file is not terminated by a CR or an LF
|
||||
(as StuffIt 1.5.1 and earlier did), but in that case a second file is not
|
||||
allowed to follow it. Last, while most hexifiers output lines of equal length,
|
||||
some do not. Hexbin will deal with that, but there are some caveats; see the
|
||||
-c option in the man page.
|
||||
|
||||
Background:
|
||||
|
||||
dl format:
|
||||
This was the first hexified format used. Programs to deal with it came
|
||||
from SUMacC. This format only coded resource forks, 4 bits in a byte.
|
||||
hex format:
|
||||
I think this is the first format from Yves Lempereur. Like dl format,
|
||||
it codes 4 bits in a byte, but is able to code both resource and
|
||||
data fork. Is it BinHex 2.0?
|
||||
hcx format:
|
||||
A compressing variant of hex format. Codes 6 bits in a byte.
|
||||
Is it BinHex 3.0?
|
||||
hqx format:
|
||||
Like hcx, but using a different coding (possibly to allow for ASCII->EBCDIC
|
||||
and EBCDIC->ASCII translation, which not always results in an identical
|
||||
file). Moreover this format also encodes the original Mac filename.
|
||||
mu format:
|
||||
The conversion can be done by the UUTool program from Octavian Micro
|
||||
Development. It encodes both forks and also some finder info. You will
|
||||
in general not use this with uudecode on non Mac systems, with uudecode
|
||||
only the data fork will be uudecoded. UU hexification is well known (and
|
||||
fairly old) in Unix environments. Moreover it has been ported to lots of
|
||||
other systems.
|
||||
-------------------------------------------------------------------------------
|
||||
Macsave reads a MacBinary stream from standard input and writes the
|
||||
files according to the options.
|
||||
-------------------------------------------------------------------------------
|
||||
Macstream reads files from the Unix host and will output a MacBinary stream
|
||||
containing all those files together with information about the directory
|
||||
structure.
|
||||
-------------------------------------------------------------------------------
|
||||
Binhex will read a MacBinary stream, or will read files/directories as
|
||||
indicated on the command line, and will output all files in binhexed (.hqx)
|
||||
format. Information about the directory structure is lost.
|
||||
-------------------------------------------------------------------------------
|
||||
Tomac will transmit a MacBinary stream, or named files to the Mac using
|
||||
the XMODEM protocol.
|
||||
-------------------------------------------------------------------------------
|
||||
Frommac will receive one or more files from the Mac using the XMODEM protocol.
|
||||
-------------------------------------------------------------------------------
|
||||
This is an ongoing project, more stuff will appear.

All comments are still welcome. Thanks for the comments I already received.

This code is based on the code described in README.ORIG.
|
||||
Changes are:
|
||||
1. A program (makecrc) will create the different C source
|
||||
files to do crc calculations.
|
||||
2. The crc calculation method of binhex is added.
|
||||
3. 32 bit crc's are added.

/* updcrc(3), crc(1) - calculate crc polynomials
|
||||
*
|
||||
* Calculate, intelligently, the CRC of a dataset incrementally given a
|
||||
* buffer full at a time.
|
||||
*
|
||||
* Usage:
|
||||
* newcrc = updcrc( oldcrc, bufadr, buflen )
|
||||
* unsigned int oldcrc, buflen;
|
||||
* char *bufadr;
|
||||
*
|
||||
* Compiling with -DTEST creates a program to print the CRC of stdin to stdout.
|
||||
* Compile with -DMAKETAB to print values for crctab to stdout. If you change
|
||||
* the CRC polynomial parameters, be sure to do this and change
|
||||
* crctab's initial value.
|
||||
*
|
||||
* Notes:
|
||||
* Regards the data stream as an integer whose MSB is the MSB of the first
|
||||
* byte recieved. This number is 'divided' (using xor instead of subtraction)
|
||||
* by the crc-polynomial P.
|
||||
* XMODEM does things a little differently, essentially treating the LSB of
|
||||
* the first data byte as the MSB of the integer. Define SWAPPED to make
|
||||
* things behave in this manner.

Preliminary info about the Unix scanner.
|
||||
----------------------------------------
|
||||
|
||||
This file states mostly how to use it, it is not yet full documentation.
|
||||
|
||||
There are a few utilities in this package that help scanning: macidf,
|
||||
macscan, macstream, hexbin and macunpack. I will give examples of use
|
||||
where every use highlights some factilities.
|
||||
|
||||
The main program is macscan. It reads from standard input (NB: no file
|
||||
parameters) and will scan the input for offensive stuff. The input
|
||||
consists of a stream of files in MacBinary format, with additional
|
||||
information between (about Unix file name, Archive/Packed file name,
|
||||
folder entry/exit in an archive etc.).
|
||||
|
||||
To scan a single MacBinary file just do:
|
||||
macscan <file
|
||||
This will read the file and macscan will mark everything it does not like.
|
||||
Also when macscan detects that it is an archive, it will unpack the archive,
|
||||
and recursively so for embedded archives. When given the opion -l macscan
|
||||
will list the contents of the archive during its scan. When given the
|
||||
option -v it will also list all resources found, with type, number,
|
||||
name (if defined) and size.
|
||||
|
||||
If you have multiple MacBinary files (e.g. a set of MacBinary files in a
|
||||
directory tree), you can do the following (supposing the filenames end in
|
||||
'.bin'):
|
||||
find directory -name '*.bin' -exec xxx {} \; | macscan
|
||||
Where xxx is the following shellscript:
|
||||
#!/bin/sh
|
||||
macidf $1
|
||||
cat $1
|
||||
The macidf is needed so that macscan knows the original Unix file name.
|
||||
Of course macscan can also get the -l and -v options.
|
||||
|
||||
If you have a directory tree with binhexed files, the following is
|
||||
appropriate:
|
||||
find directory -name '*.hqx' -exec hexbin -S {} \; | macscan
|
||||
The flag -S tells hexbin that filename info for macscan must be included.
|
||||
And here again, macscan can have options. Note: every binhexed file must
|
||||
be contained in a single Unix file, unlike mcvert. But, like mcvert,
|
||||
mailheaders and such can preceed and follow the binhexed file, and can
|
||||
also be in the middle.
|
||||
|
||||
You can of course have compressed binhexed files, in that case:
|
||||
find directory -name '*.hqx.Z' -exec xxx {} \; | macscan
|
||||
with xxx the following shellscript:
|
||||
#!/bin/sh
|
||||
macidf $1
|
||||
zcat $1 | hexbin -s
|
||||
(Note, lower case s here. Hexbin has no knowledge about the Unix filename.)
|
||||
|
||||
If the directory is an AUFS directory the following can be done:
|
||||
macstream directory | macscan
|
||||
Note: in this case it is not yet possible to include the Unix filename in
|
||||
the output of macscan. With the option -l Mac names are listed.
|
||||
|
||||
The previous method might also work with AppleDouble directories, but I am
|
||||
not sure about that.
|
||||
|
||||
-------
|
||||
What macscan can at this moment.
|
||||
|
||||
It currently uses a subset of Jeff's VirusDetective strings during the scan.
|
||||
Not all strings are yet implemented, so not all viruses are already detected.
|
||||
|
||||
Moreover, it includes warnings for CDEF 0, WDEF 0 etc. resources, as per
|
||||
Zig's suggestion.
|
||||
|
||||
Finally, it warns about resources compressed by the resource compressor of
|
||||
Ben Haller.
|
||||
|
||||
-------
|
||||
The status.
|
||||
|
||||
This version is preliminary and confidential. Do not distribute.
|
||||
There are probably a number of bugs present, although my testing
|
||||
on a Sun (actually an FPS == very fast Sun) worked pretty well.
|
||||
Lint does not complain too much ;-). Also SGI's lint has not
|
||||
many problems with it. Mostly because the difference between
|
||||
(char *)malloc();
|
||||
and
|
||||
(void *)malloc();
|
||||
etc. That must be straightened out sometime.
|
||||
|
||||
Any bug-reports, suggestions are wellcome. Please support bug-reports
|
||||
with input or somesuch.

unpit - Macintosh PackIt file unpacker
|
||||
|
||||
Version 2, for PackIt II
|
||||
|
||||
This program will unpack a Macintosh PackIt file into separate files. The
|
||||
data fork of a PackIt file contains both the data and resource forks of the
|
||||
packed files. The program will unpack each Mac file into separate .data,
|
||||
.rsrc., and .info files that can be downloaded to a Mac using macput.
|
||||
|
||||
The program syntax is much like macput/macget:
|
||||
|
||||
unpit [-rdu] packit-file.data
|
||||
|
||||
The -r and -d flags will cause only the resource and data forks to be
|
||||
written. The -u flag will cause only the data fork to be written and
|
||||
to have carriage return characters changed to Unix newline characters.
|
||||
|
||||
Some of the program is borrowed from the macput.c/macget.c programs.

/* There is some confusion as to what to do with the "inited" flag in the

|
||||
MacTerminal into placing the file icons in the upper left corner of the
|
||||
window on top of each other. Setting this bit to zero in the .info file
|
||||
seems to fix that problem but may cause others. I haven't been able to
|
||||
find any .info files that have this flag set so making it zero may be OK.
|

Anyway, MacTerminal seems to set the flag when it create the file on the

Mac. The "#define INITED_BUG" can be used to try both settings. */

unsit - Macintosh StuffIt file extractor
|
||||
|
||||
Version 1, for StuffIt 1.31
|
||||
|
||||
This program will unpack a Macintosh StuffIt file into separate files.
|
||||
The data fork of a StuffIt file contains both the data and resource
|
||||
forks of the packed files. The program will unpack each Mac file into
|
||||
separate .data, .rsrc., and .info files that can be downloaded to a
|
||||
Mac using macput. The program is much like the "unpit" program for
|
||||
breaking apart Packit archive files.
|
||||
|
||||
***** IMPORTANT *****
|
||||
To extract StuffIt files that have been compressed with the Lempel-Ziv
|
||||
compression method, unsit pipes the data through the "compress"
|
||||
program with the appropriate switches, rather than incorporate the
|
||||
uncompression routines within "unsit". Therefore, it is necessary to
|
||||
have the "compress" program on the system and in the search path to
|
||||
make "unsit" work. "Compress" is available from the comp.sources.unix
|
||||
archives.
|
||||
|
||||
The program syntax is much like unpit and macput/macget, with some added
|
||||
options:
|
||||
|
||||
unsit [-rdulvq] stuffit-file.data
|
||||
|
||||
The -r and -d flags will cause only the resource and data forks to be
|
||||
written. The -u flag will cause only the data fork to be written and
|
||||
to have carriage return characters changed to Unix newline characters.
|
||||
The -l flag will make the program only list the files in the StuffIt
|
||||
file. The -v flag causes the program to list the names, sizes, type,
|
||||
and creators of the files it is writing. The -q flag causes it to
|
||||
list the name, type and size of each file and wait for a 'y' or 'n'
|
||||
for either writing that file or skipping it, respectively.
|
||||
|
||||
Some of the program is borrowed from the macput.c/macget.c programs.
|
||||
Many, many thanks to Raymond Lau, the author of StuffIt, for including
|
||||
information on the format of the StuffIt archives in the documentation.
