... t enter.
"File" is the name of the file you want to prepare for
mailing, and yes, you have to type the name twice! The > is a Unix
command that tells the system to call the "encoded" file "file.uu"
(you could actually call it anything you want).
Now to get it into a mail message. The quick and dirty way is to
type
mail friend
where "friend" is your friend's address. At the agoura graphic designer subject line, type
the name of the enclosed file. When you get the blank line, type
~r file.uu
or whatever you called the file, and hit enter. (on some agoura graphic designer systems, the ~
may not work; if so, ask your system administrator what to use).
This
inserts the file into your mail message. Hit control-D, and your file
is on its way!
On the other end, when your friend goes into her mailbox, she
should transfer it to her home directory. Then she should type
uudecode file.name
and hit enter. This creates a new file in her name directory with
whatever name you originally gave it. She can then download it to her
own computer. Before she can actually use it, though, she'll have to
open it up with a text processor and delete the mail header that has
been "stamped" on it. If you use a mailer program that automatically
appends a "signature," tell her about that so she can delete that as
well.
9.2 RECEIVING FILES
If somebody sends you a file through the mail, you'll have to go
through a couple of steps to get it into a form you can actually use. If
you are using the simple mail program, go into mail and type
w # file.name
where # is the number of the message you want to transfer and
file.name is what you want to call the resulting file. In pine, call
up the message and hit your O key and then E. You'll then be asked
for a file name.
In elm, call up the message and hit your S key.
You'll get something that looks like this:
=file.request
Type a new file name and hit enter (if you hit enter without
typing a file name, the message will be saved to another mail folder,
not your home directory).
In all three cases, exit the mail program to return to your host
system's command line. Because the file has been encoded for mail
delivery, you now have to run a decoder.
At the command line, type
uudecode file.name
where file.name is the file you created while in mail. Uudecode will
create a new, uncompressed binary file. In some cases, you may have to
run it through some other programs (for example, if it is in "tar" form),
but generally it should now be ready for you to download to your own
computer (on which you might then have to run a de-compressor program
such as PKXZIP).
9.3 SENDING FILES TO NON-INTERNET SITES
What if your friend only connects with a non-Unix system, such as
CompuServe or MCIMail? There are programs available for MS-DOS, Apple
and Amiga computers that will encode and decode files. Of course, since
you can't send one of these programs to your friend via e-mail (how would
she un-encode it?), you'll have to mail (the old-fashioned way) or give
her a diskette with the program on it first. Then, she can get the file
by e-mail and go through the above process (only on her own computer) to
get a usable file. Remember to give her an encoder program as well, if
she wants to send you files in return.
For MS-DOS machines, you'll want to get uunecode.com and
uudecode.com. Both can be found through anonymous ftp at
wuarchive.wustl.edu in the /mirrors/msdos/starter directory. The MS-
DOS kansas graphic designer version is as easy to use as the Unix one: Just type
uudecode filename.ext
and hit enter.
agoura graphic graphic designer singapore designer Mac users should get a program called uutool, which can be found
in the info-mac/util directory on sumex-aim.stanford.edu.
Think twice bramley graphic designer before sending somebody a giant file. Although large
sites connected directly to the Internet can probably handle mega-files,
many smaller systems cannot. Some commercial systems, such as CompuServe
and MCIMail, limit the size of mail messages their users can receive. agoura graphic designer
Fidonet doesn't even allow encoded messages. In general, a file size of
30,000 or so bytes is a safe upper limit for non-Internet systems.
9.4 GETTING FTP FILES VIA E-MAIL
To help people without ftp access, a number of ftp sites have set up
mail servers (also known as archive servers) that allow you to get files
via e-mail. You send a request to one of these machines and they send
back the file you want. As with ftp, you'll be able to find everything
from historical documents to software (but please note that if you do
have access to ftp, that method is always quicker and ties up fewer
resources than using e-mail).
Some interesting or useful mail servers include:
mail-server@rtfm.mit.edu Files of "frequently asked questions"
related to Usenet; state-by-state lists of U.S. representatives and
Senators and their addresses and office phone numbers.
graphic designer singapore archive-server@eff.org Information about the Electronic Frontier
Foundation; documents about legal issues on the Net.
archive-server@cs.widener.edu Back copies of the Computer
Underground Digest and every possible fact you could want to know about
"The Simpsons."
netlib@uunet.uu.net Programs for many types ... |
