Hi. I'm graduating from college soon (2 weeks!!!), and as a result, I've been furiously FTP-ing everything in sight so I don't have to pay huge dial-up fees after I graduate.... The problemis that after I spent acouple hours downloading and ftping, I end upwith a couple hundred files that I need to debinhex. I go into Stuffit (or binhex, depending on my mood), select "decode file", select the file, and wait a bit. Then I do it again. BOOORRRRING. Doing this for a couple megs worth of files is UGLY. Real ugly. Major ugly. Getting the init that freezes the SFthingy to the current place helped, but not much. What I need is some sort of simple utilitiy that will take a folder of files and massively de-binhex them. Errors would be recorded, so I could go back afterwards and fix the files that went bad, but otherwise everything would just be automates. Anyone know of any utility like this? Anyone want to write one? :-) And while you're at it, a mass unstuffit would be nice, too, since stuffit is the de facto utility now for downloading files.... thanx -- Laura Lemay ll12+@andrew.cmu.edu

Having to break apart downloaded files is a real drag. Especially when there are a LOT of files to process. As Laura Ann Lemay (ll12+@andrew.cmu.edu) put it in article <wYNPz6y00WB44PDUoC@andrew.cmu.edu>, >The problem is that after I spent a couple hours downloading and ftping, I >end up with a couple hundred files that I need to debinhex.

Every now and then I go on a downloading spree, when I transfer pretty much everything in sight to my machine. Having to deBinHex and unStuff each file is annoying at best, but I figure it's the price I must pay to have so much great software literally at my fingertips. However, one of these days, I'd like to download the entire set of PostScript fonts from Sumex, but I've been putting it off because I don't particularly relish the idea of having to prepare each of those files one-by-one for use. I'll expand on the general request here: Does anyone know of any mass-deBinHex or mass-unStuffIt utilities that exist for either the Mac or any Unix systems? I can use my CMS system here to de-BinHex a file before I download it, making it smaller and more quickly downloaded, but I hesitate to do that on each of dozens of files at once manually. And it would be REALLY nice if I could take a BinHexed, Stuffed file on my Unix system and, in one fell swoop, download it to each of its constituent files on my Mac, each file ready to go with no further action! (Dream on...) Any leads whatsoever are more than welcome! << Brian Kendig >>

I asked about this some time ago and was directed to several utilites available ftp on sumex, in the "unix" directory. Some were more complete than others, but I could not get any of them to correctly debinhex Stuffit files. That is, uncompressed files and files compressed with Packit would de-hqx correctly online, but Stuffit files would turn out to be corrupt if I converted them first and then downloaded them. Your mileage may vary. There is a mass-unstuff available, however. If you select all of the files you wish to decompress, and hold down the Shift key after opening them, Stuffit will convert them all, and save all items from all files in the same folder with the Stuffit application. Having a multi-debinhex in Stuffit would be a dream come true. James syap@vera.cc.rochester.edu ...!rochester!vera!syap GEnie: FITZWILLIAM

This seems to be a pretty popular topic, especially recently. In light of that, I sent off the following source code to comp.sources.mac several (about 6 to be a tad more precise) weeks ago, but alas no response was heard from the moderator and no posting ever showed up. Since I am quite impatient by nature, I grew tired of waiting long ago and so here is the source code for a wonderful little program called mcvert. It is a mac<->unix file converter, and in my humble opinion (IMHO for all you acronym junkies) it is the best one out there. It was written by Doug Moore of Cornell (who gave me permission to post), so comments should be directed to him (his address is in the shar file). About the only thing it doesn't do for you is un-stuff stuffit archives. Enjoy it, everybody. --- Delete this line and everything above it ----- #!/bin/sh # This is a shell archive, meaning: # 1.

[[-options] name...]... .br .SH DESCRIPTION The .I mcvert program translates MacIntosh files from one format to another. The primary formats in which MacIntosh files are represented on non-Macs are: .TP .B MacBinary: An eight bit wide representation of the data and resource forks of a Mac file and of relevant Finder information, MacBinary files are recognized as "special" by several MacIntosh terminal emulators. These emulators, using Kermit or Xmodem or any other file transfer protocol, can separate the incoming file into forks and appropriately modify the Desktop to display icons, types, creation dates, and the like. .TP .B BinHex 4.0: A seven bit wide representation of a Mac file with CRC error checking, BinHex 4.0 files are designed for communication of Mac files over long distance, possibly noisy, seven bit wide paths. .TP .B PackIt: PackIt files are actually representations of collections of Mac files, possibly Huffman compressed. Packing many small related files together before a MacBinary transfer or a translation to BinHex 4.0 is common practice. .TP .B Text: A MacIntosh ends each line of a plain text file with a carriage return character (^M), rather than the newline character (^J) that some systems seem to prefer. Moreover, a MacBinary file has prepended Finder information that non-MacIntoshes don't need. .TP .B Data, Rsrc: A Data or Rsrc file is the exact copy of the data or resource fork of a MacIntosh file. .PP It is the purpose of this program to convert to the MacBinary format files in other of the above formats, and vice versa. .PP .SH PARAMETERS Exactly one of the following operations may be specified for an input name: .TP .B x BinHex 4.0 - files in the MacBinary format are translated to BinHex files, or vice versa. The name argument may be the name of a file to be converted or a basename to which an appropriate suffix must be appended to get a filename. If the conversion is from Binhex 4.0 to MacBinary, several files may comprise the BinHex representation of the Mac file. Rather than manually concatenate the files and manually delete mail headers and other extraneous garbage, one may specify the names of the files in order and .I mcvert will do the concatenating and deleting. Conversely, in converting a MacBinary file to BinHex 4.0 format for mailing over long distances, one may be restricted to mail messages of no greater that some fixed length. In this case, .I mcvert can automatically divide the BinHex file into pieces and label each piece appropriately. Option 'x' is selected by default. .TP .B r Resource - files in the MacBinary format with empty data forks and nonempty resource forks are made from ordinary data files, or vice versa. .TP .B d Data - files in the MacBinary format with nonempty data forks and empty resource forks are made from ordinary data files, or vice versa. .TP .B u Text - files in the MacBinary format with nonempty data forks and empty resource forks are made from ordinary data files, or vice versa. Unix newline characters are interchanged with MacIntosh carriage return characters, and a newly created MacBinary file has creator field given by the MAC_EDITOR environment variable. .PP .SH OPTIONS .TP .B p | q If a BinHex to MacBinary conversion is taking place and option 'p' is selected, any file of type "PIT " will be unpacked into its constituent parts. This option does not recursively unpack "PIT " files packed in "PIT " files. If a MacBinary to BinHex conversion is taking place, this option is currently ignored. By default, option 'q' is selected. .TP .B U | D When option 'U' is selected, the conversion that takes place is the one suitable for Uploading files. That is, the conversion is from MacBinary to something else when 'U' is selected. Conversely, option 'D', as in Download, converts from something to MacBinary. Option 'D' is the default. .TP .B s | v Normally, .I mcvert prints to stderr information about the files it is creating. Selecting option 's', as in silent, disables this reporting. Option 'v', for verbose, is the default. .SH "ENVIRONMENT VARIABLES" There are four environment variables one may use to customize the behavior of .I mcvert slightly. .TP .B MAC_EDITOR The creator of MacBinary text files produced with options -uD. The default is MACA, the creator type of MacWrite. .TP .B MAC_DLOAD_DIR The MacBinary files created when option -D is selected are placed in this directory. The default is ".", the current working directory. .TP .B MAC_EXT The MacBinary files created when option -D is selected are named according to the filename field stored in the file header, with the name extended by this suffix. The default is ".bin". .TP .B MAC_LINE_LIMIT The BinHex files created when option -U is selected may be no longer than this many lines long. Files that would otherwise exceed this line limit are broken up into several files with numbers embedded into their file names to show their order. Each such file has "Start of part x" and "End of part x" messages included where appropriate. .SH BUGS It should be possible to discard bad input now and successfully translate good input later, but bad input mostly just causes immediate termination. .PP A more diligent person would support BinHex 3.0 and BinHex 2.0 and BinHex 5000.0 B. C., but I've never seen anyone use them in three years. A more diligent person would also do something for users of macget and macput, but hopefully someone will make those programs support the MacBinary file protocol. .SH SEE ALSO xbin(1), macget(1), macput(1), xmodem(1), kermit(1) .SH AUTHOR Doug Moore, Cornell University Computer Science. Based upon .I xbin by Dave Johnson, Brown University, as modified by Guido van Rossum, and upon .I unpit by Allan G. Weber, as well as upon correspondence with several helpful readers of USENET. ------ EOF ------ ls -l mcvert.1 fi # End mcvert.1 echo '***** End of' mcvert.shar '*****' exit 0 -- Ken Konecki "A squeegee by any other name wouldn't sound as funny" e-mail:kenk@tellab5.UUCP -or- ...!uunet!tellab5!kenk U.S. Mail: 1271 Portchester Circle, Carol Stream, IL 60188

I use xbin, unstuff, and macput on my Sun workstation (or I can use them on the VAX with Ultrix), and VersaTerm at 19200 via the Sun's serial port (or the VAX at 9600 over our terminal controller). I put all the .hqx files in a directory. I use a program called comb to extract the junk from a combined multi-part .binaries item. xbin -v *.hqx (I examine the names of the unpacked files; almost always the stuffit archives match *xsit.* or *xSIT.*) foreach a (*xsit.data) unsit -v $a end (C-shell) or for a in *xsit.data do unsit -v $a done (Other shell (if I remember right)) Then after deleting the used *.hqx and *xsit.* files: foreach a (*.info) macput `basename $a .info` end (C-shell; make appropriate changes for other shells) Some possible gotchas: Even with the latest changes, some characters in filenames break xbin. I don't bother; I generally ship the .hqx file to the Mac and do it by hand. If you do a lot of files at once, a later file with the same name as an earlier file could wipe the earlier one out (e.g. two files named READ_ME). READ_ME and Read_Me would co-exist on the Unix system OK but could be a problem on the Mac (I forget what Versaterm does). This is why I use the -v(erbose) options above. This is what works for me. I could make it more automated, but I don't do it often enough to make it worth while. /JBL UUCP: {backbone}!bbn!levin POTS: (617) 873-3463 INTERNET: levin@bbn.com

(Dream on...) I went away on vacation a few weeks ago and, paranoid that I might miss some gem of a posting to comp.binaries.mac, I finally got around to finishing off my c.b.m archiver. I have a (Ksh) script to rescue the individual articles out of the news area, a lex program that parses Subject: lines in order to rename articles by posting title and part number, a C program that strips out news wrappers and assembles multi-part postings, and then a modified version of Dave Johnson's xbin utility (our source here is dated 09/30/85 -- there's no doubt a more recent version) patched by me to generate AUFS files instead of MacBinary files. The end result is that I no longer need to read c.b.m: I just connect to the CAP/AUFS server and do a view by date to see what's new. I suppose I could go one step further and use unsit to uncompress any StuffIt archives, but I prefer to leave them compressed to save server disk space. To get back to your problem though, if you are using a Unix system, I'd suggest you get a copy of xbin and do your unbinhexing under Unix. Uncompressing StuffIt archives on the Mac is easy enough: just select all the archives you want to uncompress, double click to launch StuffIt, and hold down the shift key until it starts uncompressing. If you're interested in any of the things I mentioned above, the following caveats apply: the lex Subject parser is still subject (:-) to periodic tweaking whenever someone posts an article in some bizarre new format, and I have seen other similar utilities advertised; the C program that strips out news gunk is trivial enough that you can probably write it yourself in the time it would take me to send it to you; and I am unwilling to distribute patches to xbin without knowing what the most recent general release of it is.

First, the method I have been using. Get "mcvert" from sumex or elsewhere and use it on your unix box to convert hqx files (it handles part?.hqx pieces without any intervention) to SIT, PIT, etc bin files. Download those binary files with a macbinary xmodem, ftp, etc and then use stuffit's multiple file unstuffing capability. Today I wrote the following c-shell "prog" to create "ready to go" binary files from hqx files. Problem 1: hqx files have to be joined if they are in parts. Problem 2: some icons are not making it on applications; I don't know why. Problem 3: It handles only SIT files. OF course, you must have xbin, unsit, unxbin and mcvert from sumex! Use at your own risk!! ===cut here==== #!/bin/csh foreach f ($*) echo "Running xbin on file "$f xbin $f echo "Completed xbin on "$f foreach g (*[S,s][I,i][T,t].data) echo "Running unsit on file "$g unsit $g echo "Completed unsit on "$g rm -f $g:r.* end foreach g (*data) echo "Running unxbin and mcvert on file "$g unxbin $g:r mcvert $g:r.hqx echo "Completed unxbin and mcvert on file" $g rm -f $g:r.data $g:r.info $g:r.rsrc $g:r.hqx end echo "Completed file "$f end echo "Completed all hqx files" ====== Stephen M.

It is a very good program. But it would really be nice if it could undecode Stuffit archives. For instance, last week I downloaded a MacIntosh Technical Note over a 2400 baud link. When I unarchived it, I discovered that it comprised 3 files: a MacWrite, a Word, and a FullWrite version of the same document. What a waste. If I had a utility to unsit the file on unix, I could just download what I need. In article <39671@bbn.COM>, levin@bbn (Joel B Levin) writes: >I use xbin, unstuff, and macput on my Sun workstation...

Unfortunately, since I gave you permission to post, all the mail I've sent to you has bounced back to me, which is why I haven't been able to tell you that: Mcvert appeared on sumex-aim about a month ago and I quickly learned that there was a bug affecting Sun 3/60's. I fixed it and have been unable to get the update to you. So I guess I'll get it to you now. It follows this message. You can divide the stuff that follows into four parts, one for each file updated, and run "patch" on each one to update the source files. I agree with those who say that it would be nice if mcvert could decode stuffit archives. When I wrote it two years ago, Packit was hot and I included unpacking capability. Now, I don't have a lot of time for it. Sorry. Others are welcome to improve it as they wish. If anyone says that it would be nice if mcvert could produce .data, .rsrc and .info files compatible with macput and macget, I disagree. It's macput and macget that should be changed. But I'm not going to do that anytime soon either.
