... learning e-mail is to send yourself a
message. Most public-access sites actually have several different types
of mail systems, all of which let you both send and receive mail.
We'll
start with the simplest one, known, appropriately enough, as "mail," and
then look at a couple of other interfaces. At your host system's command
prompt, type:
mail username
where username is the name you gave yourself when you first logged on.
Hit enter. The computer might respond with
subject:
Type
test
or, actually, anything at all (but you'll have to hit enter before
you get to the end of the screen). Hit enter.
The cursor will drop down a line. You can now begin writing the
actual message. Type a sentence, again, anything at all.
And here's
where you hit your first Unix frustration, one that will bug you
repeatedly: you have to hit enter before you get to the very end of the
line. Just like typewriters, many Unix programs have no word-wrapping
(although there are ways to get some Unix text processors, such as emacs,
to word-wrap).
When done with your message, hit return. Now hit control-D (the
control and the D keys at the same time). This is a Unix command that
tells the computer you're done writing and that it should close your
"envelope" and mail it off (you could also hit enter once and then, on
a blank line, type a period at the beginning of the line and hit enter
again).
You've just sent your first e-mail message.
And because you're
sending mail to yourself, rather than to someone somewhere else on the
Net, your message has already arrived, as we'll see in a web service seixal moment.
If you had wanted, you could have even mi web service written your message on
your own computer and then uploaded it into this electronic
"envelope." There are a couple of good reasons to do this with long
or involved messages. One is that once you hit enter at the end of a
line in "mail" you can't readily fix any mistakes on that line (unless
you use web service seixal some special commands to call up a Unix text processor). Also,
if you are paying for access by the hour, uploading a prepared
message can save you money. Remember to save the document in ASCII or
text format. Uploading a document you've created in a word processor
that uses special formatting commands (which these days means many
programs) will cause strange effects.
When you get that blank line after the subject line, upload the
message using the ASCII protocol. hosting seixal Or you can copy and paste the text,
if your software allows that. When done, hit control-D as above.
Now you have mail waiting for you. Normally, when you log on,
your public-access site will tell you whether you have new mail
waiting. To open your mailbox and see your waiting mail, type
mail
and hit enter.
When the host system sees "mail" without a name after it, it
knows you want to look in your mailbox rather than send a message.
Your screen, on a plain-vanilla Unix system will display:
Mail version SMI 4.0 Mon Apr 24 18:34:15 PDT 1989 Type ? for help.
"/usr/spool/mail/adamg": 1 message 1 new 1 unread
>N 1 adamg Sat Jan 15 20:04 12/290 test
Ignore the first line; it's just computerese of value only to the
people who run your system. You can type a question mark and hit
return, but unless you're familiar with Unix, most of what you'll see
won't make much sense at this point.
The second line tells you the directory on the host system where
your mail messages are put, which again, is not something seixal web design you'll likely
need to know. The second line also tells you how many messages are in your
mailbox, how many have come in since the last time you looked and how
many messages you haven't read yet.
It's the third line that is of real interest -- it tells you who
the message is from, when it arrived, how many lines and characters
it takes up, and what the subject is. The "N" means it is a new
message -- it arrived after the last time you looked in your mailbox.
Hit enter.
And there's your web service seixal message -- only now it's a lot
longer than what you wrote!

Subject: test
Status: R
This is only a test!
Whoa! What is all that stuff? It's your message with a postmark
gone mad. Just as the postal service puts its marks on every piece of
mail it handles, so do Net postal systems. Only it's called a
"header" instead of a postmark. Each system that handles or routes
your mail puts its stamp on it. Since many messages go through a
number of seixal web design systems on their way to you, you will often get messages
with headers that seem to go on forever. Among other things, a header
will tell you exactly when a message was sent and received (even the
difference between your local time and Greenwich Mean Time -- as at the end
of line 4 above).
If this had been a long message, it would just keep scrolling
across and down your screen -- unless the people who run your public-
access site have set it up to pause every 24 lines. One way to deal
with a message that doesn't stop is to use your telecommunication
software's logging or text-buffer function. Start it before you hit
the number of the message you want to see. Your computer will ask you
what you want to call the file you're about to create. After you name
the file and hit enter, type the number of the message you want to see
and hit enter. When the message finishes scrolling, turn off the
text-buffer function. The message is now saved in your computer.
This way, you can read the message while not connected to the Net
(which can save you money if you're paying by the hour) and write a
reply offline.
But in the meantime, now what? You can respond to the message,
delete it or save it. To respond, type a lowercase r and hit
enter.
You'll get something like this:
To: adamg
Subject: Re: test
Note that this time, you don't have to enter a user name. The
computer takes it from the message you're replying to and
automatically addresses your message to its sender. The computer also
automatically inserts a subject line, by adding "Re:" to the original
subject. From here, it's just like writing a new message. But say you
change your mind and decide not to reply after all. How do you get out
of the message? Hit control-C once. You'll get this:
(Interrupt -- one more to kill letter)
If you hit control-C once more, the message will disappear and you'll
get back to your mail's command line.
Now, if you type a lowercase d and then hit enter, you'll
delete the original message. Type a lowercase q to exit your
mailbox.
If you type a q without first hitting d, your message is
transferred to a file called mbox. This file is where all read, but
un-deleted messages go. If you want to leave it in your mailbox for
now, type a lowercase x and hit enter. This gets you out of mail
without making any changes.
The mbox file works a lot like your mailbox. To access it,
type
mail -f mbox
at your host system's command line and hit enter.
You'll get a menu identical to the one in your mailbox from which
you can read these old messages, delete them or respond to them. It's
probably a good idea to clear out your mailbox and mbox file from
time to time, if only to keep them uncluttered.
Are there any drawbacks to e-mail? There are a few. One is that
people seem more willing to fly off the handle electronically than in
person, or over the phone. Maybe it's because it's so easy to hit r
and reply to a message without pausing and reflecting a moment.
That's why we have smileys (see section 2.4)! There's no online
equivalent yet of a return receipt: chances are your message got to where
it's going, but there's no absolute way for you to know for sure unless
you get a reply from the other person.
So now you're ready to send mi web service e-mail to other people on the Net.
Of course, you need somebody's address to send them mail. How do you
get it?
Alas, the simplest answer is not what you'd call the most
elegant: you call them up on the phone or write them a letter on paper
and ask them. Residents of the electronic frontier are only beginning
to develop the equivalent of phone seixal web design books, and the ones that exist
today are far from complete (still, later on, in Chapter 6, we'll show
you how to use some of these directories).
Eventually, you'll start corresponding with people, which means
you'll want to know how to address mail to them.
It's vital to know
how to do this, because the smallest mistake -- using a comma when you
should have used a period, for instance, can bounce the message back
to you, undelivered. In this sense, Net addresses are like phone
numbers: one wrong digit and you ge ... |
