8: .sh 1 "Additional features"
9: .pp
10: This section describes some additional commands useful for
11: reading your mail, setting options, and handling lists of messages.
12: .sh 2 "Message lists"
13: .pp
14: Several
15: .i Mail
16: commands accept a list of messages as an argument.
17: Along with
18: .b type
19: and
20: .b delete ,
21: described in section 2,
22: there is the
23: .b from
24: command, which prints the message headers associated with the
25: message list passed to it.
26: The
27: .b from
28: command is particularly useful in conjunction with some of the
29: message list features described below.
30: .pp
31: A
32: .i "message list"
33: consists of a list of message numbers, ranges, and names,
34: separated by spaces or tabs. Message numbers may be either
35: decimal numbers, which directly specify messages, or one of the
36: special characters
37: .q \(ua
38: .q "."
39: or
40: .q "$"
41: to specify the first relevant, current, or last
42: relevant message, respectively.
43: .i Relevant
44: here means, for most commands
45: .q "not deleted"
46: and
47: .q "deleted"
48: for the
49: .b undelete
50: command.
51: .pp
52: A range of messages consists of two message numbers (of the form
53: described in the previous paragraph) separated by a dash.
54: Thus, to print the first four messages, use
55: .(l
56: type 1\-4
57: .)l
58: and to print all the messages from the current message to the last
59: message, use
60: .(l
61: type .\-$
62: .)l
63: .pp
64: A
65: .i name
66: is a user name. The user names given in the message list are
67: collected together and each message selected by other means
68: is checked to make sure it was sent by one of the named users.
69: If the message consists entirely of user names, then every
70: message sent by one of those users that is
71: .i relevant
72: (in the sense described earlier)
73: is selected. Thus, to print every message sent to you by
74: .q root,
75: do
76: .(l
77: type root
78: .)l
79: .pp
80: As a shorthand notation, you can specify simply
81: .q *
82: to get every
83: .i relevant
84: (same sense)
85: message. Thus,
86: .(l
87: type *
88: .)l
89: prints all undeleted messages,
90: .(l
91: delete *
92: .)l
93: deletes all undeleted messages, and
94: .(l
95: undelete *
96: .)l
97: undeletes all deleted messages.
98: .pp
99: You can search for the presence of a word in subject lines with
100: .b / .
101: For example, to print the headers of all messages that contain the
102: word
103: .q PASCAL,
104: do:
105: .(l
106: from /pascal
107: .)l
108: Note that subject searching ignores upper/lower case differences.
109: .sh 2 "List of commands"
110: .pp
111: This section describes all the
112: .i Mail
113: commands available when
114: receiving mail.
115: .ip "\fB\-\fP\ \ "
116: The
117: .rb \-
118: command goes to the previous message and prints it. The
119: .rb \-
120: command may be given a decimal number
121: .i n
122: as an argument, in which case the
123: .i n th
124: previous message is gone to and printed.
125: .ip "\fB?\fP\ \ "
126: Prints a brief summary of commands.
127: .ip "\fB!\fP\ \ "
128: Used to preface a command to be executed by the shell.
129: .ip "\fBPrint\fP\ \ "
130: Like
131: .b print ,
132: but also print out ignored header fields. See also
133: \fBprint\fP, \fBignore\fP and \fBretain\fP.
134: \fBPrint\fP can be abbreviated to \fBP\fP.
135: .ip "\fBReply\fP or \fBRespond\fP\ \ "
136: Note the capital \fBR\fP in the name.
137: Frame a reply to a one or more messages.
138: The reply (or replies if you are using this on multiple messages)
139: will be sent ONLY to the person who sent you the message
140: (respectively, the set of people who sent the messages you are
141: replying to).
142: You can
143: add people using the \fB~t\fP, \fB~c\fP and \fB~b\fP
144: tilde escapes. The subject in your reply is formed by prefacing the
145: subject in the original message with
146: .q "Re:"
147: unless it already began thus.
148: If the original message included a
149: .q "reply-to"
150: header field, the reply will go
151: .i only
152: to the recipient named by
153: .q "reply-to."
154: You type in your message using the same conventions available to you
155: through the
156: .b mail
157: command.
158: The
159: .b Reply
160: command is especially useful for replying to messages that were sent
161: to enormous distribution groups when you really just want to
162: send a message to the originator. Use it often.
163: \fBReply\fP (and \fBRespond\fP) can be abbreviated to \fBR\fP.
164: .ip "\fBType\fP\ \ "
165: Identical to the
166: .b Print
167: command.
168: \fBType\fP can be abbreviated to \fBT\fP.
169: .ip "\fBalias\fP\ \ "
170: Define a name to stand for a set of other names.
171: This is used when you want to send messages to a certain
172: group of people and want to avoid retyping their names.
173: For example
174: .(l
175: alias project john sue willie kathryn
176: .)l
177: creates an alias
178: .i project
179: which expands to the four people John, Sue, Willie, and Kathryn.
180: If no arguments are given, all currently-defined aliases are printed.
181: If one argument is given, that alias is printed (if it exists).
182: \fBAlias\fP can be abbreviated to \fBa\fP.
183: .ip "\fBalternates\fP\ \ "
184: If you have accounts on several machines, you may find it convenient
185: to use the /usr/lib/aliases on all the machines except one to direct
186: your mail to a single account.
187: The
188: .b alternates
189: command is used to inform
190: .i Mail
191: that each of these other addresses is really
192: .i you .
193: .i Alternates
194: takes a list of user names and remembers that they are all actually you.
195: When you
196: .b reply
197: to messages that were sent to one of these alternate names,
198: .i Mail
199: will not bother to send a copy of the message to this other address (which
200: would simply be directed back to you by the alias mechanism).
201: If
202: .i alternates
203: is given no argument, it lists the current set of alternate names.
204: .b Alternates
205: is usually used in the .mailrc file.
206: \fBAlternates\fP can be abbreviated to \fBalt\fP.
207: .ip "\fBchdir\fP\ \ "
208: The
209: .b chdir
210: command allows you to change your current directory.
211: .b Chdir
212: takes a single argument, which is taken to be the pathname of
213: the directory to change to. If no argument is given,
214: .b chdir
215: changes to your home directory.
216: \fBChdir\fP can be abbreviated to \fBc\fP.
217: .ip "\fBcopy\fP\ \ "
218: The
219: .b copy
220: command does the same thing that
221: .b save
222: does, except that it does not mark the messages it is used on
223: for deletion when you quit.
224: \fBCopy\fP can be abbreviated to \fBco\fP.
225: .ip "\fBdelete\fP\ \ "
226: Deletes a list of messages. Deleted messages can be reclaimed
227: with the
228: .b undelete
229: command.
230: \fBDelete\fP can be abbreviated to \fBd\fP.
231: .ip "\fBdp\fP or \fBdt\fP\ \ "
232: These
233: commands delete the current message and print the next message.
234: They are useful for quickly reading and disposing of mail.
235: If there is no next message, \fImail\fP says ``at EOF.''
236: .ip "\fBedit\fP\ \ "
237: To edit individual messages using the text editor, the
238: .b edit
239: command is provided. The
240: .b edit
241: command takes a list of messages as described under the
242: .b type
243: command and processes each by writing it into the file
244: Message\c
245: .i x
246: where
247: .i x
248: is the message number being edited and executing the text editor on it.
249: When you have edited the message to your satisfaction, write the message
250: out and quit, upon which
251: .i Mail
252: will read the message back and remove the file.
253: .b Edit
254: can be abbreviated to
255: .b e .
256: .ip "\fBelse\fP\ \ "
257: Marks the end of the then-part of an
258: .b if
259: statement and the beginning of the
260: part to take effect if the condition of the
261: .b if
262: statement is false.
263: .ip "\fBendif\fP\ \ "
264: Marks the end of an
265: .b if
266: statement.
267: .ip "\fBexit\fP or \fBxit\fP\ \ "
268: Leave
269: .i Mail
270: without updating the system mailbox or the file your were reading.
271: Thus, if you accidentally delete several messages, you can use
272: .b exit
273: to avoid scrambling your mailbox.
274: \fBExit\fP can be abbreviated to \fBex\fP or \fBx\fP.
275: .ip "\fBfile\fP\ \ "
276: The same as
277: .b folder .
278: \fBFile\fP can be abbreviated to \fBfi\fP.
279: .ip "\fBfolders\fP\ \ "
280: List the names of the folders in your folder directory.
281: .ip "\fBfolder\fP\ \ "
282: The
283: .b folder
284: command switches to a new mail file or folder. With no arguments, it
285: tells you which file you are currently reading. If you give
286: it an argument, it will write out changes (such as deletions)
287: you have made in the current file and read the new file.
288: Some special conventions are recognized for the name:
289: .(b
290: .TS
291: center;
292: c c
293: l a.
294: Name Meaning
295: _
296: # Previous file read
297: % Your system mailbox
298: %name \fIName\fP's system mailbox
299: & Your ~/mbox file
300: +folder A file in your folder directory
301: .TE
302: .)b
303: \fBFolder\fP can be abbreviated to \fBfo\fP.
304: .ip "\fBfrom\fP\ \ "
305: The
306: .b from
307: command takes a list of messages and prints out the header lines for each one;
308: hence
309: .(l
310: from joe
311: .)l
312: is the easy way to display all the message headers from \*(lqjoe.\*(rq
313: \fBFrom\fP can be abbreviated to \fBf\fP.
314: .ip "\fBheaders\fP\ \ "
315: When you start up
316: .i Mail
317: to read your mail, it lists the message headers that you have.
318: These headers tell you who each message is from, when they were
319: received, how many lines and characters each message is, and the
320: .q "Subject:"
321: header field of each message, if present. In addition,
322: .i Mail
323: tags the message header of each message that has been the object
324: of the
325: .b preserve
326: command with a
327: .q P.
328: Messages that have been
329: .b saved
330: or
331: .b written
332: are flagged with a
333: .q *.
334: Finally,
335: .b deleted
336: messages are not printed at all. If you wish to reprint the current
337: list of message headers, you can do so with the
338: .b headers
339: command. The
340: .b headers
341: command (and thus the initial header listing)
342: only lists the first so many message headers.
343: The number of headers listed depends on the speed of your
344: terminal.
345: This can be overridden by specifying the number of headers you
346: want with the
347: .i window
348: option.
349: .i Mail
350: maintains a notion of the current
351: .q window
352: into your messages for the purposes of printing headers.
353: Use the
354: .b z
355: command to move forward and back a window.
356: You can move
357: .i Mail's
358: notion of the current window directly to a particular message by
359: using, for example,
360: .(l
361: headers 40
362: .)l
363: to move
364: .i Mail's
365: attention to the messages around message 40.
366: If a ``+'' argument is given, then the next screenful of message headers is
367: printed, and if a ``\-'' argument is given, the previous screenful of message
368: headers is printed.
369: \fBHeaders\fP can be abbreviated to \fBh\fP.
370: .ip "\fBhelp\fP\ \ "
371: Print a brief and usually out of date help message about the commands
372: in
373: .i Mail .
374: The
375: .i man
376: page for
377: .i mail
378: is usually more up-to-date than either the help message or this manual.
379: It is also a synonym for \fB?\fP.
380: .ip "\fBhold\fP\ \ "
381: Arrange to hold a list of messages in the system mailbox, instead
382: of moving them to the file
383: .i mbox
384: in your home directory. If you set the binary option
385: .i hold ,
386: this will happen by default.
387: It does not override the \fBdelete\fP command.
388: \fBHold\fP can be abbreviated to \fBho\fP.
389: .ip "\fBif\fP\ \ "
390: Commands in your
391: .q .mailrc
392: file can be executed conditionally depending on whether you are
393: sending or receiving mail with the
394: .b if
395: command. For example, you can do:
396: .(l
397: if receive
398: \fIcommands\fP...
399: endif
400: .)l
401: An
402: .b else
403: form is also available:
404: .(l
405: if send
406: \fIcommands\fP...
407: else
408: \fIcommands\fP...
409: endif
410: .)l
411: Note that the only allowed conditions are
412: .b receive
413: and
414: .b send .
415: .ip "\fBignore\fP \ \ "
416: .b N.B.:
417: .i Ignore
418: has been superseded by
419: .i retain.
420: .br
421: Add the list of header fields named to the
422: .i "ignore list" .
423: Header fields in the ignore list are not printed on your
424: terminal when you print a message. This allows you to suppress
425: printing of certain machine-generated header fields, such as
426: .i Via
427: which are not usually of interest. The
428: .b Type
429: and
430: .b Print
431: commands can be used to print a message in its entirety, including
432: ignored fields.
433: If
434: .b ignore
435: is executed with no arguments, it lists the current set of ignored fields.
436: .ip "\fBlist\fP\ \ "
437: List the valid
438: .i Mail
439: commands.
440: \fBList\fP can be abbreviated to \fBl\fP.
441: .. .ip \fBlocal\fP
442: .. Define a list of local names for this host. This command is useful
443: .. when the host is known by more than one name. Names in the list
444: .. may be qualified be the domain of the host. The first name on the local
445: .. list is the
446: .. .i distinguished
447: .. name of the host.
448: .. The names on the local list are used by
449: .. .i Mail
450: .. to decide which addresses are local to the host.
451: .. For example:
452: .. .(l
453: .. local ucbarpa.BERKELEY.ARPA arpa.BERKELEY.ARPA \\
454: .. arpavax.BERKELEY.ARPA r.BERKELEY.ARPA \\
455: .. ucb-arpa.ARPA
456: .. .)l
457: .. From this list we see that
458: .. .i "[email protected]",
459: .. .i "[email protected]",
460: .. and
461: .. .i "larry@r"
462: .. are all addresses of users on the local host.
463: .. The
464: .. .b local
465: .. command is usually not used be general users since it is designed for
466: .. local configuration; it is usually found in the file /usr/lib/Mail.rc.
467: .ip "\fBmail\fP\ \ "
468: Send mail to one or more people. If you have the
469: .i ask
470: option set,
471: .i Mail
472: will prompt you for a subject to your message. Then you
473: can type in your message, using tilde escapes as described in
474: section 4 to edit, print, or modify your message. To signal your
475: satisfaction with the message and send it, type control-d at the
476: beginning of a line, or a . alone on a line if you set the option
477: .i dot .
478: To abort the message, type two interrupt characters (\s-2RUBOUT\s0
479: by default) in a row or use the
480: .b ~q
481: escape.
482: The \fBmail\fP command can be abbreviated to \fBm\fP.
483: .ip "\fBmbox\fP\ \ "
484: Indicate that a list of messages be sent to
485: .i mbox
486: in your home directory when you quit. This is the default
487: action for messages if you do
488: .i not
489: have the
490: .i hold
491: option set.
492: .ip "\fBnext\fP or \fB+\fP\ \ "
493: The
494: .b next
495: command goes to the next message and types it. If given a message list,
496: .b next
497: goes to the first such message and types it. Thus,
498: .(l
499: next root
500: .)l
501: goes to the next message sent by
502: .q root
503: and types it. The
504: .b next
505: command can be abbreviated to simply a newline, which means that one
506: can go to and type a message by simply giving its message number or
507: one of the magic characters
508: .q "^"
509: .q "."
510: or
511: .q "$".
512: Thus,
513: .(l
514: \&.
515: .)l
516: prints the current message and
517: .(l
518: 4
519: .)l
520: prints message 4, as described previously.
521: \fBNext\fP can be abbreviated to \fBn\fP.
522: .ip "\fBpreserve\fP\ \ "
523: Same as
524: .b hold .
525: Cause a list of messages to be held in your system mailbox when you quit.
526: \fBPreserve\fP can be abbreviated to \fBpre\fP.
527: .ip "\fBprint\fP\ \ "
528: Print the specified messages. If the
529: .b crt
530: variable is set, messages longer than the number of lines it indicates
531: are paged through the command specified by the \fBPAGER\fP variable.
532: The \fBprint\fP command can be abbreviated to \fBp\fP.
533: .ip "\fBquit\fP\ \ "
534: Terminates the session, saving all undeleted, unsaved and unwritten messages
535: in the user's \fImbox\fP file in their login directory
536: (messages marked as having been read), preserving all
537: messages marked with \fBhold\fP or \fBpreserve\fP or never referenced
538: in their system mailbox.
539: Any messages that were deleted, saved, written or saved to \fImbox\fP are
540: removed from their system mailbox.
541: If new mail has arrived during the session, the message
542: ``You have new mail'' is given. If given while editing a mailbox file
543: with the \fB\-f\fP flag, then the edit file is rewritten.
544: A return to the Shell is effected, unless the rewrite of edit file fails,
545: in which case the user can escape with the \fBexit\fP command.
546: \fBQuit\fP can be abbreviated to \fBq\fP.
547: .ip "\fBreply\fP or \fBrespond\fP\ \ "
548: Frame a reply to a single message.
549: The reply will be sent to the
550: person who sent you the message (to which you are replying), plus all
551: the people who received the original message, except you. You can
552: add people using the \fB~t\fP, \fB~c\fP and \fB~b\fP
553: tilde escapes. The subject in your reply is formed by prefacing the
554: subject in the original message with
555: .q "Re:"
556: unless it already began thus.
557: If the original message included a
558: .q "reply-to"
559: header field, the reply will go
560: .i only
561: to the recipient named by
562: .q "reply-to."
563: You type in your message using the same conventions available to you
564: through the
565: .b mail
566: command.
567: The \fBreply\fP (and \fBrespond\fP) command can be abbreviated to \fBr\fP.
568: .ip "\fBretain\fP\ \ "
569: Add the list of header fields named to the \fIretained list\fP.
570: Only the header fields in the retain list
571: are shown on your terminal when you print a message.
572: All other header fields are suppressed.
573: The
574: .b Type
575: and
576: .b Print
577: commands can be used to print a message in its entirety.
578: If
579: .b retain
580: is executed with no arguments, it lists the current set of
581: retained fields.
582: .ip "\fBsave\fP\ \ "
583: It is often useful to be able to save messages on related topics
584: in a file. The
585: .b save
586: command gives you the ability to do this. The
587: .b save
588: command takes as an argument a list of message numbers, followed by
589: the name of the file in which to save the messages. The messages
590: are appended to the named file, thus allowing one to keep several
591: messages in the file, stored in the order they were put there.
592: The filename in quotes, followed by the line
593: count and character count is echoed on the user's terminal.
594: An example of the
595: .b save
596: command relative to our running example is:
597: .(l
598: s 1 2 tuitionmail
599: .)l
600: .b Saved
601: messages are not automatically saved in
602: .i mbox
603: at quit time, nor are they selected by the
604: .b next
605: command described above, unless explicitly specified.
606: \fBSave\fP can be abbreviated to \fBs\fP.
607: .ip "\fBset\fP\ \ "
608: Set an option or give an option a value. Used to customize
609: .i Mail .
610: Section 5.3 contains a list of the options. Options can be
611: .i binary ,
612: in which case they are
613: .i on
614: or
615: .i off ,
616: or
617: .i valued .
618: To set a binary option
619: .i option
620: .i on ,
621: do
622: .(l
623: set option
624: .)l
625: To give the valued option
626: .i option
627: the value
628: .i value ,
629: do
630: .(l
631: set option=value
632: .)l
633: There must be no space before or after the ``='' sign.
634: If no arguments are given, all variable values are printed.
635: Several options can be specified in a single
636: .b set
637: command.
638: \fBSet\fP can be abbreviated to \fBse\fP.
639: .ip "\fBshell\fP\ \ "
640: The
641: .b shell
642: command allows you to
643: escape to the shell.
644: .b Shell
645: invokes an interactive shell and allows you to type commands to it.
646: When you leave the shell, you will return to
647: .i Mail .
648: The shell used is a default assumed by
649: .i Mail ;
650: you can override this default by setting the valued option
651: .q SHELL,
652: eg:
653: .(l
654: set SHELL=/bin/csh
655: .)l
656: \fBShell\fP can be abbreviated to \fBsh\fP.
657: .ip "\fBsize\fP\ \ "
658: Takes a message list and prints out the size in characters of each
659: message.
660: .ip "\fBsource\fP\ \ "
661: The
662: .b source
663: command reads
664: .i mail
665: commands from a file. It is useful when you are trying to fix your
666: .q .mailrc
667: file and you need to re-read it.
668: \fBSource\fP can be abbreviated to \fBso\fP.
669: .ip "\fBtop\fP\ \ "
670: The
671: .b top
672: command takes a message list and prints the first five lines
673: of each addressed message.
674: If you wish, you can change the number of lines that
675: .b top
676: prints out by setting the valued option
677: .q "toplines."
678: On a CRT terminal,
679: .(l
680: set toplines=10
681: .)l
682: might be preferred.
683: \fBTop\fP can be abbreviated to \fBto\fP.
684: .ip "\fBtype\fP\ \ "
685: Same as \fBprint\fP.
686: Takes a message list and types out each message on the terminal.
687: The \fBtype\fP command can be abbreviated to \fBt\fP.
688: .ip "\fBundelete\fP \ \"
689: Takes a message list and marks each message as \fInot\fP
690: being deleted.
691: \fBUndelete\fP can be abbreviated to \fBu\fP.
692: .ip "\fBunread\fP\ \ "
693: Takes a message list and marks each message as
694: .i not
695: having been read.
696: \fBUnread\fP can be abbreviated to \fBU\fP.
697: .ip "\fBunset\fP\ \ "
698: Takes a list of option names and discards their remembered values;
699: the inverse of \fBset\fP .
700: .ip "\fBvisual\fP\ \ "
701: It is often useful to be able to invoke one of two editors,
702: based on the type of terminal one is using. To invoke
703: a display oriented editor, you can use the
704: .b visual
705: command. The operation of the
706: .b visual
707: command is otherwise identical to that of the
708: .b edit
709: command.
710: .ne 2v+\n(psu
711: .sp \n(psu
712: Both the
713: .b edit
714: and
715: .b visual
716: commands assume some default text editors. These default editors
717: can be overridden by the valued options
718: .q EDITOR
719: and
720: .q VISUAL
721: for the standard and screen editors. You might want to do:
722: .(l
723: set EDITOR=/usr/ucb/ex VISUAL=/usr/ucb/vi
724: .)l
725: \fBVisual\fP can be abbreviated to \fBv\fP.
726: .ip "\fBwrite\fP\ \ "
727: The
728: .b save
729: command always writes the entire message, including the headers,
730: into the file. If you want to write just the message itself, you
731: can use the
732: .b write
733: command. The
734: .b write
735: command has the same syntax as the
736: .b save
737: command, and can be abbreviated to simply
738: .b w .
739: Thus, we could write the second message by doing:
740: .(l
741: w 2 file.c
742: .)l
743: As suggested by this example, the
744: .b write
745: command is useful for such tasks as sending and receiving
746: source program text over the message system.
747: The filename in quotes, followed by the line
748: count and character count is echoed on the user's terminal.
749: .ip "\fBz\fP\ \ "
750: .i Mail
751: presents message headers in windowfuls as described under
752: the
753: .b headers
754: command.
755: You can move
756: .i Mail's
757: attention forward to the next window by giving the
758: .(l
759: z+
760: .)l
761: command. Analogously, you can move to the previous window with:
762: .(l
763: z\-
764: .)l
765: .sh 2 "Custom options"
766: .pp
767: Throughout this manual, we have seen examples of binary and valued options.
768: This section describes each of the options in alphabetical order, including
769: some that you have not seen yet.
770: To avoid confusion, please note that the options are either
771: all lower case letters or all upper case letters. When I start a sentence
772: such as:
773: .q "Ask"
774: causes
775: .i Mail
776: to prompt you for a subject header,
777: I am only capitalizing
778: .q ask
779: as a courtesy to English.
780: .ip "\fBEDITOR\fP\ \ "
781: The valued option
782: .q EDITOR
783: defines the pathname of the text editor to be used in the
784: .b edit
785: command and ~e. If not defined, a standard editor is used.
786: .ip "\fBPAGER\fP\ \ "
787: Pathname of the program to use for paginating output when
788: it exceeds \fIcrt\fP lines.
789: A default paginator is used if this option is not defined.
790: .ip "\fBSHELL\fP\ \ "
791: The valued option
792: .q SHELL
793: gives the path name of your shell. This shell is used for the
794: .b !
795: command and ~! escape. In addition, this shell expands
796: file names with shell metacharacters like * and ? in them.
797: .ip "\fBVISUAL\fP\ \ "
798: The valued option
799: .q VISUAL
800: defines the pathname of the screen editor to be used in the
801: .b visual
802: command
803: and ~v escape. A standard screen editor is used if you do not define one.
804: .ip "\fBappend\fP\ \ "
805: The
806: .q append
807: option is binary and
808: causes messages saved in
809: .i mbox
810: to be appended to the end rather than prepended.
811: Normally, \fIMail\fP will put messages in \fImbox\fP
812: in the same order that the system puts messages in your system mailbox.
813: By setting
814: .q append,
815: you are requesting that
816: .i mbox
817: be appended to regardless. It is in any event quicker to append.
818: .ip "\fBask\fP\ \ "
819: .q "Ask"
820: is a binary option which
821: causes
822: .i Mail
823: to prompt you for the subject of each message you send.
824: If you respond with simply a newline, no subject field will be sent.
825: .ip "\fBaskcc\fP\ \ "
826: .q Askcc
827: is a binary option which
828: causes you to be prompted for additional carbon copy recipients at the
829: end of each message. Responding with a newline shows your
830: satisfaction with the current list.
831: .ip "\fBautoprint\fP\ \ "
832: .q Autoprint
833: is a binary option which
834: causes the
835: .b delete
836: command to behave like
837: .b dp
838: \*- thus, after deleting a message, the next one will be typed
839: automatically. This is useful when quickly scanning and deleting
840: messages in your mailbox.
841: .ip "\fBcrt\fP \ \ "
842: The valued option
843: .I crt
844: is used as a threshold to determine how long a message must
845: be before
846: .b PAGER
847: is used to read it.
848: .ip "\fBdebug\fP \ \ "
849: The binary option
850: .q debug
851: causes debugging information to be displayed. Use of this
852: option is the same as using the \fB\-d\fP command line flag.
853: .ip "\fBdot\fP\ \ "
854: .q Dot
855: is a binary option which, if set, causes
856: .i Mail
857: to interpret a period alone on a line as the terminator
858: of the message you are sending.
859: .ip "\fBescape\fP\ \ "
860: To allow you to change the escape character used when sending
861: mail, you can set the valued option
862: .q escape.
863: Only the first character of the
864: .q escape
865: option is used, and it must be doubled if it is to appear as
866: the first character of a line of your message. If you change your escape
867: character, then ~ loses all its special meaning, and need no longer be doubled
868: at the beginning of a line.
869: .ip "\fBfolder\fP\ \ "
870: The name of the directory to use for storing folders of messages.
871: If this name begins with a `/'
872: .i Mail
873: considers it to be an absolute pathname; otherwise, the folder directory
874: is found relative to your home directory.
875: .ip "\fBhold\fP\ \ "
876: The binary option
877: .q hold
878: causes messages that have been read but not manually dealt with
879: to be held in the system mailbox. This prevents such messages from
880: being automatically swept into your \fImbox\fP file.
881: .ip "\fBignore\fP\ \ "
882: The binary option
883: .q ignore
884: causes \s-2RUBOUT\s0 characters from your terminal to be ignored and echoed
885: as @'s while you are sending mail. \s-2RUBOUT\s0 characters retain their
886: original meaning in
887: .i Mail
888: command mode.
889: Setting the
890: .q ignore
891: option is equivalent to supplying the
892: .b \-i
893: flag on the command line as described in section 6.
894: .ip "\fBignoreeof\fP\ \ "
895: An option related to
896: .q dot
897: is
898: .q ignoreeof
899: which makes
900: .i Mail
901: refuse to accept a control\-d as the end of a message.
902: .q Ignoreeof
903: also applies to
904: .i Mail
905: command mode.
906: .ip "\fBkeep\fP\ \ "
907: The
908: .q keep
909: option causes
910: .i Mail
911: to truncate your system mailbox instead of deleting it when it
912: is empty. This is useful if you elect to protect your mailbox, which
913: you would do with the shell command:
914: .(l
915: chmod 600 /usr/spool/mail/yourname
916: .)l
917: where
918: .i yourname
919: is your login name. If you do not do this, anyone can probably read
920: your mail, although people usually don't.
921: .ip "\fBkeepsave\fP\ \ "
922: When you
923: .b save
924: a message,
925: .i Mail
926: usually discards it when you
927: .b quit .
928: To retain all saved messages, set the
929: .q keepsave
930: option.
931: .ip "\fBmetoo\fP\ \ "
932: When sending mail to an alias,
933: .i Mail
934: makes sure that if you are included in the alias, that mail will not
935: be sent to you. This is useful if a single alias is being used by
936: all members of the group. If however, you wish to receive a copy of
937: all the messages you send to the alias, you can set the binary option
938: .q metoo.
939: .ip "\fBnoheader\fP\ \ "
940: The binary option
941: .q noheader
942: suppresses the printing of the version and headers when
943: .i Mail
944: is first invoked. Setting this option is the same as using
945: .b \-N
946: on the command line.
947: .ip "\fBnosave\fP\ \ "
948: Normally,
949: when you abort a message with two \s-2RUBOUTs\s0,
950: .i Mail
951: copies the partial letter to the file
952: .q dead.letter
953: in your home directory. Setting the binary option
954: .q nosave
955: prevents this.
956: .ip "\fBReplyall\fP\ \ "
957: Reverses the sense of
958: .i reply
959: and
960: .i Reply
961: commands.
962: .ip "\fBquiet\fP\ \ "
963: The binary option
964: .q quiet
965: suppresses the printing of the version when
966: .i Mail
967: is first invoked,
968: as well as printing the for example
969: .q "Message 4:"
970: from the
971: .b type
972: command.
973: .ip "\fBrecord\fP\ \ "
974: If you love to keep records, then the
975: valued option
976: .q record
977: can be set to the name of a file to save your outgoing mail.
978: Each new message you send is appended to the end of the file.
979: .ip "\fBscreen\fP\ \ "
980: When
981: .i Mail
982: initially prints the message headers, it determines the number to
983: print by looking at the speed of your terminal. The faster your
984: terminal, the more it prints.
985: The valued option
986: .q screen
987: overrides this calculation and
988: specifies how many message headers you want printed.
989: This number is also used for scrolling with the
990: .b z
991: command.
992: .ip "\fBsendmail\fP\ \ "
993: To use an alternate mail delivery system, set the
994: .q sendmail
995: option to the full pathname of the program to use. Note: this is not
996: for everyone! Most people should use the default delivery system.
997: .ip "\fBtoplines\fP\ \ "
998: The valued option
999: .q toplines
1000: defines the number of lines that the
1001: .q top
1002: command will print out instead of the default five lines.
1003: .ip "\fBverbose\fP\ \ "
1004: The binary option "verbose" causes
1005: .i Mail
1006: to invoke sendmail with the
1007: .b \-v
1008: flag, which causes it to go into verbose mode and announce expansion
1009: of aliases, etc. Setting the "verbose" option is equivalent to
1010: invoking
1011: .i Mail
1012: with the
1013: .b \-v
1014: flag as described in section 6.
