nedmail – reading mail

upas/nedmail [ –nr ] [ –f mailfile ] [ –s mailfile ]

upas/nedmail –c dir

Nedmail edits a mailbox. The default mailbox is /mail/box/username/mbox. The –f command line option specifies an alternate mailbox. Unrooted path names are interpreted relative to /mail/box/username. If the mailfile argument is omitted, the name defaults to stored.

The options are:
c dir         Create a mailbox. If dir is specified, the new mailbox is created in /mail/box/username/dir/mbox. Otherwise, the default mailbox is created.
r           Reverse: show messages in first–in, first–out order; the default is last–in, first–out.
n           Make the message numbers the same as the file names in the mail box directory. This implies the –r option.
f mailfile      Read messages from the specified file (see above) instead of the default mailbox.
s mailfile      Read a single message file mailfile, as produced by fs, and treat it as an entire mailbox. This is provided for use in plumbing rules; see faces(1).

Nedmail starts by reading the mail box, printing out the number of messages, and then prompting for commands from standard input. Commands, as in ed(1), are of the form `[range] command [arguments]'. The command is applied to each message in the (optional) range.

The address range can be:
address          to indicate a single message header
address,address    to indicate a range of contiguous message headers
g/expression/      to indicate all messages whose headers match the regular expression.
g%expression%      to indicate all messages whose contents match the regular expression.

The addresses can be:
number          to indicate a particular message
address.number    to indicate a subpart of a particular message
/expression/       to indicate the next message whose header matches expression
%expression%       to indicate the next message whose contents match expression
empty or .         to indicate the current message
address         to indicate backwards search or movement

Since messages in MIME are hierarchical structures, in nedmail all the subparts are individually addressable. For example if message 2 contains 3 attachments, the attachments are numbered 2.1, 2.2, and 2.3.

The commands are:
a args        Reply to all addresses in the To:, From:, and Cc: header lines. Marshal is used to format the reply and any arguments the user specifies are added to the command line to marshal before the recipient. The possibility of making a fool of yourself is very high with this command. A args        Like a but with the message appended to the reply.
b           Print the headers for the next ten messages.
d           Mark message to be deleted upon exiting nedmail.
f           Append the message to the file /mail/box/username/sendername where sendername is the account name of the sender.
h           Print the disposition, size in characters, reception time, sender, and subject of the message.
H           Print the MIME structure of the message.
help         Print a summary of the commands.
m person ...     Forward the message as a mime attachment to the named persons.
M person ...     Like m but allow the user to type in text to be included with the forwarded message.
p           Print message. An interrupt stops the printing.
r args        Reply to the sender of the message. Marshal is used to format the reply. If any optional Args are specified, they are added to the command line to marshal before the recipient's address.
R    args      Like r but with the original message included as an attachment.
rf           Like r but append the message and the reply to the file /mail/box/username/sendername where sendername is the account name of the sender.
Rf           Like R but append the message and the reply to the file /mail/box/username/sendername where sendername is the account name of the sender.
s mfile        Append the message to the specified mailbox. If mfile doesn't start with a `/', it is interpreted relative to the directory in which the mailbox resides. If mfile is a directory then the destination is a file in that directry. If the MIME header specifies a file name, that one is used. Otherwise, one is
generated using mktemp(2) and the string att.XXXXXXXXXXX.
q           Put undeleted mail back in the mailbox and stop.
EOT (control–D)Same as q.
w file         Same as s with the mail header line(s) stripped. This can be used to save binary mail bodies.
u           Remove mark for deletion.
x           Exit, without changing the mailbox file.
y           Synchronize with the mail box. Any deleted messages are purged and any new messages read. This is equivalent to quiting nedmail and restarting.
|command     Run the command with the message body as standard input.
||command    Run the command with the whole message as standard input.
!command     Escape to the shell to do command.
=           Print the number of the current message.

Here's an example of a mail session that looks at a summary of the mail messages, saves away an html file added as an attachment to a message and then deletes the message:

% mail

Notice that the delete of message 1.2 deleted the entire message and not just the attachment.
