.SH DESCRIPTION
.I Nedmail
edits a mailbox.
The default mailbox is
.BI /mail/box/ username /mbox\f1.
The
.B -f
command line option specifies an alternate mailbox.
Unrooted path names are interpreted relative to
.BI /mail/box/ username.
If the
.I mailfile
argument is omitted, the name defaults to
.BR stored .
.PP
The options are:
.TF "-f mailfile"
.TP
.BI -c " dir
Create a mailbox.  If
.I dir
is specified, the new mailbox is created in
.BI /mail/box/ username / dir /mbox\f1.
Otherwise, the default mailbox is created.
.TP
.B -r
Reverse: show messages in first-in, first-out order; the default is last-in, first-out.
.TP
.B -n
Make the message numbers the same as the file names in the mail
box directory.  This implies the
.B -r
option.
.TP
.BI -f " mailfile"
Read messages from the specified file (see above) instead of the default mailbox.
.TP
.BI -s " mailfile"
Read a single message file
.IR mailfile ,
as produced by
.IR fs ,
and treat it as an entire mailbox.
This is provided for
use in plumbing rules; see
.IR faces (1).
.PD
.PP
.I Nedmail
starts by reading the mail box, printing out the number
of messages, and then prompting for commands from standard input.
Commands, as in
.IR ed (1),
are of the form
.RI `[ range ]
.I command
.RI [ arguments ]'.
The command is applied to each message in the (optional) range.
.PP
The address range can be:
.TP 1.4i
.I address
to indicate a single message header
.PD 0
.TP
.IB address , address
to indicate a range of contiguous message headers
.TP
.BI g/ expression /
to indicate all messages whose headers match the regular
.IR expression .
.TP
.BI g% expression %
to indicate all messages whose contents match the regular
.IR expression .
.PD
.PP
The addresses can be:
.TP 1.4i
.I number
to indicate a particular message
.PD 0
.TP
.IB address . number
to indicate a subpart of a particular message
.TP
.BI / expression /
to indicate the next message whose header matches
.I expression
.TP
.BI % expression %
to indicate the next message whose contents match
expression
.TP
.I "empty or .
to indicate the current message
.TP
.BI - address
to indicate backwards search or movement
.PD
.PP
Since messages in MIME are hierarchical
structures, in
.I 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.
.PP
The commands are:
.TP 1.1i
.BI a " args
Reply to all addresses in the
.BR To: ,
.BR From: ,
and
.BR Cc:
header lines.
.I Marshal
is used to format the reply and any arguments the
user specifies are added to the command line to
.I marshal
before the recipient.
The possibility of making a fool of yourself is very
high with this command.
.PD 0
.TP
.BI A " args
Like 
.B a
but with the message
appended to the reply.
.TP
.B b
Print the headers for the next ten messages.
.TP
.B d
Mark message to be deleted upon exiting
.IR nedmail .
.TP
.B f
Append the message to the file 
.BI /mail/box/ username / sendername
where
.I sendername
is the account name of the sender.
.TP
.B h
Print the disposition, size in characters, reception time, sender,
and subject of the message.
.TP
.B H
Print the MIME structure of the message.
.TP
.B help
Print a summary of the commands.
.TP
.BI m " person ...
Forward the message as a mime attachment to the named
.IR persons .
.TP
.BI M " person ...
Like
.B m
but allow the user to type in text to be included
with the forwarded message.
.TP
.B p
Print message.
An interrupt stops the printing.
.TP
.BI r " args
Reply to the sender of the message.
.I Marshal
is used to format the reply.
If any optional
.I args
are specified, they are added to the command line to
.I marshal
before the recipient's address.
.TP
.BI R " args 
Like
.B r
but with the original message included as an attachment.
.TP
.B rf
Like
.B r
but append the message and the reply to the file 
.BI /mail/box/ username / sendername
where
.I sendername
is the account name of the sender.
.TP
.B Rf
Like 
.B R
but append the message and the reply to the file 
.BI /mail/box/ username / sendername
where
.I sendername
is the account name of the sender.
.TP
.BI s " mfile"
Append the message to the specified mailbox.
If
.I mfile
doesn't start with a `/', it is interpreted relative to the directory in which the mailbox resides.
If
.I 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
.IR mktemp (2)
and the string
.BR att.XXXXXXXXXXX .
.TP
.B q
Put undeleted mail back in the mailbox and stop.
.TP
EOT (control-D)
Same as 
.BR q .
.TP
.BI w " file

save binary mail bodies.
.TP
.B u
Remove mark for deletion.
.TP
.B x
Exit, without changing the mailbox file.
.TP
.B y
Synchronize with the mail box.  Any deleted
messages are purged and any new messages read.
This is equivalent to quiting nedmail and restarting.
.TP
.BI | command
Run the
.I command
with the message body as standard input.
.TP
.BI || command
Run the
.I command
with the whole message as standard input.
.TP
.BI ! command
Escape to the shell to do
.IR command .
.TP
.B \&=
Print the number of the current message.
.PD
.PP
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:
.LP
.EX
% mail
