Reading Mail: inc, show, next, prev
[previous]
[next]
[table of contents] [index]
With the messages that you and your friend sent, you should have at
least five new messages waiting by now.
You can't read the messages until you incorporate them from your
system mailbox into your account.
To do this, type inc at the shell prompt (%).
For example:
% inc
Incorporating new mail into inbox...

Okay -- what's all that?
Here's an explanation of the output from inc:
-
The inc command got all your new mail from your system mailbox (the
place that new mail waits for you) and moved it into your inbox folder.
-
There were six new messages, which inc numbered 1 through 6.
(If there were already some messages in your inbox, then inc
would have started numbering the new messages one higher than the last
message already in inbox.)
-
There's a one-line summary of each message called a scan listing.
It shows the message number, the date when the message was sent,
who sent it,
and the Subject: field, if any.
(The date order will be different -- date/month instead of
month/date -- if MH was configured with its
[UK] option.)
If there's room on the screen, you'll see the first few words of the
message body (with the two left angle brackets (<<) first).
-
One message has a plus sign (+) next to the number.
In a scan listing, the + marks the current message.
The + isn't part of the message number;
MH just puts it in the scan line.
To read the first message you incorporated,
type show and press
RETURN.
You'll see the current message (in this case, message number 1) on your
screen.
Your screen will look something like this:
% show
(Message inbox:1)

Hi, Angela! You asked me to send you a message. Here it is.
I hope this is okay and that you can figure out how to use
that mail system.
Joe
The message header has information
(fields such as Received:) that you can usually ignore.
Your message may have more, fewer, or other header fields.
You can configure show to skip header fields you don't want;
see Using mhl.
If the message is longer than one screen, most users just see the first
screenful.
(What happens depends on your version of UNIX and how your MH package
was set up.)
Then, until all of the message has been shown, and depending on how your
account is set up:
-
There may be a prompt like -- More -- ,
or a single colon (:), at the bottom of your screen.
-
Your terminal may beep.
-
The screen may just sit still.
No matter what happens, if your screen pauses before the end of the message,
try pressing the space bar or
RETURN
to get the next screenful of the message.
When you've seen the message, you should get another shell prompt
(%) on the screen.
(In some setups, you may need to type q, for "quit," first.)
Now, to look at the next message, type next at the shell prompt.
The display will be just like the one you got with the show
command, but you'll see the next message (in this case, message number 2).
Message 2 becomes the new current message.
When you're done reading message 2, type prev.
This shows the previous message.
(For example, if you've just seen message 2,
prev will show message 1.)
Because MH commands are used at a shell prompt (%), you can use all
the other standard UNIX commands with them, too.
For instance, assuming your system's printer command is named lpr,
you can print the current message by sending
show's output to the printer, like this:
% show | lpr
You can copy the current message to a file with:
% show > filename
and so on -- output redirection works with other MH commands, too.
NOTE:
MIME messages are usually difficult to redirect to a file because they
may start multiple viewers, print prompts, and so on.
A command like
cp `mhpath cur` filename
will help.
The mimecat script decodes a
MIME message and can also extract individual parts.
The current message is number 1 again.
Let's skip over message 2 and go straight to message 3.
Do that by giving the message number to the show command:
% show 3
Use next or show to read all other mail except the MIME
message from the O'Reilly server.
We'll get to it in Section Using MIME.
