55: mailx \- interactive message processing system
56: .SH SYNOPSIS
57: .B mailx
58: [options] [address ...]
59: .SH DESCRIPTION
60: The command
61: \f2mailx\f1 provides a comfortable, flexible environment for sending and
62: receiving messages electronically.
63: When reading mail,
64: \*(Ma provides commands to facilitate saving, deleting, and responding to
65: messages.
66: When sending mail,
67: \*(Ma allows editing, reviewing and other modification of the message
68: as it is entered.
69: .PP
70: Incoming mail is stored in a standard file for each user,
71: called the \*(mx for that user.
72: When \*(Ma is called to read messages,
73: the \*(mx is the default place to find them.
74: As messages are read,
75: they may be marked to be moved to a secondary file for storage
76: (see ``hold''),
77: unless specific action is taken,
78: so that the messages need not be seen again.
79: This secondary file is called the \*(mb
80: and is normally located in the user's \s-1HOME\s+1 directory
81: (see ``\s-1MBOX\s+1'').
82: Messages can be saved in other secondary files named by the user.
83: Messages remain in a secondary file until forcibly removed.
84: .PP
85: The user can access a secondary file by using the
86: \f3\-f\f1 option of the \*(Ma command.
87: Messages in the secondary file can then be read or otherwise
88: processed using the same \*(CM as in the primary \*(mx.
89: This gives rise within these pages to the notion of a current \*(mx.
90: .PP
91: On the command line,
92: .I options
93: start with a dash (\-) and any other arguments are taken to be
94: addresses.
95: If no recipients are specified,
96: \*(Ma will attempt to read messages from the \*(mx.
97: Command line options are:
98: .PP
99: .PD 0
100: .TP 14
101: .B \-e
102: Test for presence of mail.
103: \f2mailx\f1 prints nothing and exits with a successful return code if there is
104: mail to read.
105: .TP
106: .BR \-f \ [\*(fn]
107: Read messages from \*(fn instead of \*(mx.
108: If no \*(fn is specified,
109: the \*(mb is used.
110: .TP
111: .B \-F
112: Record the message in a file named after the first recipient.
113: Overrides the ``record'' variable, if set.
114: .TP
115: .B \-H
116: Print header summary only.
117: .TP
118: .B \-i
119: Ignore interrupts.
120: See ``ignore''.
121: .TP
122: .B \-n
123: Do not initialize from the system default
124: .I mailx.rc
125: file.
126: .TP
127: .B \-N
128: Do not print initial header summary.
129: .TP
130: .BI \-s \ subject
131: Set the Subject header field to
132: .IR subject .
133: .TP
134: .BI \-u \ user
135: Read
136: .IR user 's
137: \*(mx.
138: This is only effective if
139: .IR user 's
140: \*(mx is not read protected.
141: .PD
142: .PP
143: When reading mail,
144: \*(Ma is in
145: command mode.
146: A header summary of the first several messages is displayed,
147: followed by a prompt indicating \*(Ma can accept regular commands
148: (see \*(CM below).
149: When sending mail,
150: \*(Ma is in
151: input mode.
152: If no subject is specified on the command line,
153: a prompt for the subject is printed.
154: As the message is typed,
155: \*(Ma will read the message and store it in a temporary
156: file.
157: Commands may be entered by beginning a line with the tilde (~) escape
158: character followed by a single command letter and optional arguments.
159: See \*(Te for a summary of these commands.
160: Outgoing mail may be saved in a local file (see ``record'').
161: .PP
162: At any time,
163: the behavior of \*(Ma is governed by a set of
164: \f2environment variables\f1.
165: These are flags and valued parameters which are set and cleared via the
166: ``set'' and ``unset'' commands.
167: See \*(EV below for a summary of these parameters.
168: .PP
169: \*(Ma accepts \fIpost\fP addressing.
170: Login names may be any network address,
171: including mixed network addressing.
172: If mail is found to to undeliverable, an attempt is
173: made to return it to the sender's \f2mailbox\f1.
174: If the recipient name begins with a plus (+),
175: the rest of the name is a file to append the mail to.
176: If the file is a relative path name, it is prepended
177: with the value of the ``folder'' variable.
178: If the recipient name begins with a pipe symbol (|),
179: the rest of the name is taken to be a shell command to pipe the
180: message through.
181: This provides an automatic interface with any program that reads the standard
182: input, such as
183: .IR lp (1)
184: for recording outgoing mail on paper.
185: Alias groups are set by the ``alias'' command
186: and are lists of recipients of any type.
187: .PP
188: Regular commands are of the form
189: .ti +.5i
190: [
191: .B command
192: ] [
193: .I msglist
194: ] [
195: .I arguments
196: ]
197: .br
198: If no command is specified in command mode,
199: .BR p rint
200: is assumed.
201: In input mode,
202: commands are recognized by the escape character,
203: and lines not treated as commands are taken as input for the message.
204: .PP
205: Each message is assigned a sequential number,
206: and there is at any time the notion of a current message,
207: marked by a right angle bracket (>) in the header summary.
208: Many commands take an optional list of messages
209: (\*(ml) to operate on.
210: The default for \f2msglist\f1 is the current message.
211: A \*(ml is a list of message identifiers separated by spaces,
212: which may include:
213: .PP
214: .PD 0
215: .TP 8
216: .B n
217: Message number
218: .BR n .

237: .BR user ,
238: where
239: .B user
240: is the network address of the sender.
241: .TP

243: All messages with
244: .B string
245: in the subject line (case ignored).

271: Note that the context of the command determines whether this type of
272: message specification makes sense.
273: .PD
274: .PP
275: Other arguments are usually arbitrary strings whose usage
276: depends on the command involved.
277: File names,
278: where expected,
279: are expanded via the normal shell conventions (see
280: .IR sh (1)).
281: Special characters are recognized by certain commands and are
282: documented with the commands below.
283: .PP
284: At start-up time,
285: \*(Ma tries to execute commands from the optional system-wide file
286: (\f3/usr/lib/mailx.rc\f1) to initialize
287: certain parameters,
288: then from a private start-up file (\f3$HOME/.mailrc\f1) for
289: personalized variables.
290: With the exceptions noted below,
291: regular commands are legal inside start-up files.
292: The most common use of a start-up file is
293: to set up initial display options and alias lists.
294: The following commands are not legal in the start-up file:
295: ``!'', ``Copy'', ``edit'', ``followup'', ``Followup'', ``hold'',
296: ``mail'', ``reply'', ``Reply'', ``shell'', and ``visual''.
297: An error in the start-up file causes the remaining lines in the file to
298: be ignored.
299: The \f3.mailrc\f1 file is optional, and must be constructed locally.
