.SH NAME
mailx \- interactive message processing system
.SH SYNOPSIS
.B mailx
[options] [address ...]
.SH DESCRIPTION
The command
\f2mailx\f1 provides a comfortable, flexible environment for sending and
receiving messages electronically.
When reading mail,
\*(Ma provides commands to facilitate saving, deleting, and responding to
messages.
When sending mail,
\*(Ma allows editing, reviewing and other modification of the message
as it is entered.
.PP
Incoming mail is stored in a standard file for each user,
called the \*(mx for that user.
When \*(Ma is called to read messages,
the \*(mx is the default place to find them.
As messages are read,
they may be marked to be moved to a secondary file for storage
(see ``hold''),
unless specific action is taken,
so that the messages need not be seen again.
This secondary file is called the \*(mb
and is normally located in the user's \s-1HOME\s+1 directory
(see ``\s-1MBOX\s+1'').
Messages can be saved in other secondary files named by the user.
Messages remain in a secondary file until forcibly removed.
.PP
The user can access a secondary file by using the 
\f3\-f\f1 option of the \*(Ma command.
Messages in the secondary file can then be read or otherwise
processed using the same \*(CM as in the primary \*(mx.
This gives rise within these pages to the notion of a current \*(mx.
.PP
On the command line,
.I options
start with a dash (\-) and any other arguments are taken to be
addresses.
If no recipients are specified,
\*(Ma will attempt to read messages from the \*(mx.
Command line options are:
.PP
.PD 0
.TP 14
.B \-e
Test for presence of mail.
\f2mailx\f1 prints nothing and exits with a successful return code if there is
mail to read.
.TP
.BR \-f \ [\*(fn]
Read messages from \*(fn instead of \*(mx.
If no \*(fn is specified,
the \*(mb is used.
.TP
.B \-F
Record the message in a file named after the first recipient.
Overrides the ``record'' variable, if set.
.TP
.B \-H
Print header summary only.
.TP
.B \-i
Ignore interrupts.
See ``ignore''.
.TP
.B \-n
Do not initialize from the system default
.I mailx.rc
file.
.TP
.B \-N
Do not print initial header summary.
.TP
.BI \-s \ subject
Set the Subject header field to
.IR subject .
.TP
.BI \-u \ user
Read
.IR user 's
\*(mx.
This is only effective if
.IR user 's
\*(mx is not read protected.
.PD
.PP
When reading mail,
\*(Ma is in
command mode.
A header summary of the first several messages is displayed,
followed by a prompt indicating \*(Ma can accept regular commands
(see \*(CM below).
When sending mail,
\*(Ma is in
input mode.
If no subject is specified on the command line,
a prompt for the subject is printed.
As the message is typed,
\*(Ma will read the message and store it in a temporary
file.
Commands may be entered by beginning a line with the tilde (~) escape
character followed by a single command letter and optional arguments.
See \*(Te for a summary of these commands.
Outgoing mail may be saved in a local file (see ``record'').
.PP
At any time,
the behavior of \*(Ma is governed by a set of
\f2environment variables\f1.
These are flags and valued parameters which are set and cleared via the
``set'' and ``unset'' commands.
See \*(EV below for a summary of these parameters.
.PP
\*(Ma accepts \fIpost\fP addressing.
Login names may be any network address,
including mixed network addressing.
If mail is found to to undeliverable, an attempt is
made to return it to the sender's \f2mailbox\f1.
If the recipient name begins with a plus (+),
the rest of the name is a file to append the mail to.
If the file is a relative path name, it is prepended
with the value of the ``folder'' variable.
If the recipient name begins with a pipe symbol (|),
the rest of the name is taken to be a shell command to pipe the
message through.
This provides an automatic interface with any program that reads the standard
input, such as
.IR lp (1)
for recording outgoing mail on paper.
Alias groups are set by the ``alias'' command
and are lists of recipients of any type.
.PP
Regular commands are of the form
.ti +.5i
[
.B command
] [
.I msglist
] [
.I arguments
]
.br
If no command is specified in command mode,
.BR p rint
is assumed.
In input mode,
commands are recognized by the escape character,
and lines not treated as commands are taken as input for the message.
.PP
Each message is assigned a sequential number,
and there is at any time the notion of a current message,
marked by a right angle bracket (>) in the header summary.
Many commands take an optional list of messages
(\*(ml) to operate on. 
The default for \f2msglist\f1 is the current message.
A \*(ml is a list of message identifiers separated by spaces,
which may include:
.PP
.PD 0
.TP 8
.B n
Message number
.BR n .
.TP
.B .
The current message.
.TP
.B ^
The first message.
.TP
.B $
The last message.
.TP
.B *
All messages.
.TP
.B n\-m
An inclusive range of message numbers.
.TP
.B user
All messages from
.BR user ,
where
.B user
is the network address of the sender.
.TP
.B /string
All messages with
.B string
in the subject line (case ignored).
.TP
.BI : c
All messages of type
.IR c ,
where
.I c
is one of:
.RS 13
.TP
.B d
deleted messages
.TP
.B n
new messages
.TP
.B o
old messages
.TP
.B r
read messages
.TP
.B u
unread messages
.RE
.PP
Note that the context of the command determines whether this type of
message specification makes sense.
.PD
.PP
Other arguments are usually arbitrary strings whose usage
depends on the command involved.
File names,
where expected,
are expanded via the normal shell conventions (see
.IR sh (1)).
Special characters are recognized by certain commands and are
documented with the commands below.
.PP
At start-up time,
\*(Ma tries to execute commands from the optional system-wide file
(\f3/usr/lib/mailx.rc\f1) to initialize
certain parameters,
then from a private start-up file (\f3$HOME/.mailrc\f1) for
personalized variables.
With the exceptions noted below, 
regular commands are legal inside start-up files.
The most common use of a start-up file is 
to set up initial display options and alias lists.
The following commands are not legal in the start-up file:
``!'', ``Copy'', ``edit'', ``followup'', ``Followup'', ``hold'',
``mail'', ``reply'', ``Reply'', ``shell'', and ``visual''.
An error in the start-up file causes the remaining lines in the file to
be ignored.
The \f3.mailrc\f1 file is optional, and must be constructed locally.
.SS \*(CM
The following is a complete list of \*(Ma commands:
.PP
.PD 0

the response is saved at the end of that file.
See ``flipr''.
.Cm s ave [\*(fn]
.C s ave \*(om \*(fn
Save the specified messages in the given file.
The file is created if it does not exist.
The message is deleted from the \*(mx when
\*(Ma terminates unless ``keepsave'' is set
(see the ``exit'' and ``quit'' commands).
.Cm S ave \*(om
Save the specified messages in a file whose name is derived from
the author of the first message.

.PD
.SS \*(EV
The following are environment variables taken from the execution environment and
are not alterable within \*(Ma.
.PD 0
.Va \s-1HOME\s+1 \*(dr
The user's base of operations.
.Va \s-1MAILRC\s+1 \*(fn
The name of the start-up file.
Default is \fB$HOME/.mailrc\fR.
.PD
.PP
The following variables are internal \*(Ma variables.
They may be imported from the execution environment or

The ``unset'' command may be used to erase variables.
.PD 0
.V allnet
.Va allnet \fBuucp\f1
.Va allnet \fBany\f1
.Va allnet \fBheader\f1
All network names whose last component (login name) match are treated as
identical.
If
.B uucp
is the argument, all network names whose two last components
(system and login name) that match are treated as identical.
This causes the \*(ml message specifications to behave similarly.
If
.B any
is the argument,
.I user
is treated as a pattern to be matched anywhere in the first
line of a message (similar to /bin/mail).
.If
.B header
is the argument,
.I user
is treated as a pattern to be used in a case-independent match
of either the network address in the first line of a message or
the full name, as printed by the ``headers'' command.
Default is ``allnet=any''.
See also the ``alternates'' command and the ``metoo'' variable.
