Grex Info Item 206: Binary Newsgroups
Entered by peacefrg on Sat Feb 4 15:32:43 UTC 1995:

When I'm in a binary newsgroup and want to download a picture how do
I get pictures that are 3-4 postings long? I download each posting
individually but then I have 4 pieces of the same picture.
I cant get them to go togethor to make one big picture.

12 responses total.

You need to combine them in an editor, and remove the mail headers from
all but the first post. Make sure they're in the right order, too.
Since all postings are text, you will be manipulating text, so an
editor can handle it. After you have combined them into a single file, you'll
run whatever you would have run to convert the file into a binary format
(such as uudecode).

Amazing coincidence. I was just sent uuencoded .zip file in three
pieces, and puzzled over exactly the same thing. I did concatenate
them, downloaded and unzipped, but got error messages. So I stripped
the headers on 2 and 3, and tried again. Success! I combined them
on a unix machine with  >cat file1 file2 file3 > fullfile, rather
than in an editor.

There are uu-decode-type programs out there that will a) ignore
mail or Usenet header information and b) automatically combine multi-
part files, assuming a particular naming sequence (like fyle.1, fyle.2,
etc. ).  One program that at least ignores headers is uud.

Yes Valerie, I uudecoded before downloading...(mumble, mumble, mumble..).

The easiest way, of course, is to type "e" at
the "What next?" prompt after each article, and it will
extract the binary file for you.  Make sure you do each
article in order, or it won't work.

You know any of those program names Kent?

Robh, what you said is completely meaningless to me, but seems to pose 
the most promise of being of help.  Could you elaborate?

Thanks.

Okay, I'll give it a shot - if you're using rn or trn, (and this
probably applies to tin too but I never use it so I'm not sure),
if you've loaded an article with part or all of a uuencoded
binary, hitting "e" at the "what next?" prompt will uudecode
that file/section-of-file.  If you're suing some other software
to read Usenet, then that won't work obviously.

They're all awful, but why take them to court?


#11 of 12 by gixxie11 on Sun Mar 30 01:35:27 2003:

How exactly does the uudecoding process work I understand binary coding just
not how the uudecoding process works can anyone give me some clearifacation
on how it is done?
