This is ! 71: particularly useful when using ! 72: .I mail ! 73: on noisy phone lines. ! 74: The ! 75: .B \-n ! 76: flag inhibits the reading of /usr/lib/Mail.rc. ! 77: .PP ! 78: .I "Sending mail.\ " ! 79: To send a message to one or more people, ! 80: .I mail ! 81: can be invoked with arguments which are the names of people to ! 82: whom the mail will be sent. You are then expected to type in ! 83: your message, followed ! 84: by an \s-2EOT\s0 (control\-D) at the beginning of a line. ! 85: A subject may be specified on the command line by using the ! 86: .B \-s ! 87: flag. (Only the first argument after the ! 88: .B \-s ! 89: flag is used as a subject; be careful to quote subjects ! 90: containing spaces.) ! 91: The section below, labeled ! 92: .I "Replying to or originating mail," ! 93: describes some features of ! 94: .I mail ! 95: available to help you compose your letter. ! 96: .PP ! 97: .I "Reading mail.\ " ! 98: In normal usage ! 99: .I mail ! 100: is given no arguments and checks your mail out of the ! 101: post office, then ! 102: prints out a one line header of each message there. ! 103: The current message is initially the first message (numbered 1) ! 104: and can be printed using the ! 105: .B print ! 106: command (which can be abbreviated \fBp\fR). ! 107: You can move among the messages much as you move between lines in ! 108: .IR ed , ! 109: with the commands `+' and `\-' moving backwards and forwards, and ! 110: simple numbers. ! 111: .PP ! 112: .I "Disposing of mail.\ " ! 113: After examining a message you can ! 114: .B delete ! 115: (\fBd\fR) ! 116: the message or ! 117: .B reply ! 118: (\fBr\fR) ! 119: to it. ! 120: Deletion causes the ! 121: .I mail ! 122: program to forget about the message. ! 123: This is not irreversible; the message can be ! 124: .B undeleted ! 125: (\fBu\fR) ! 126: by giving its number, or the ! 127: .I mail ! 128: session can be aborted by giving the ! 129: .B exit ! 130: (\fBx\fR) ! 131: command. ! 132: Deleted messages will, however, usually disappear never to be seen again. ! 133: .PP ! 134: .I "Specifying messages.\ " ! 135: Commands such as ! 136: .B print ! 137: and ! 138: .B delete ! 139: can be given a list of message numbers as arguments to apply ! 140: to a number of messages at once. ! 141: Thus ``delete 1 2'' deletes messages 1 and 2, while ``delete 1\-5'' ! 142: deletes messages 1 through 5. ! 143: The special name ``*'' addresses all messages, and ``$'' addresses ! 144: the last message; thus the command ! 145: .B top ! 146: which prints the first few lines of a message could be used in ! 147: ``top *'' to print the first few lines of all messages. ! 148: .PP ! 149: .I "Replying to or originating mail.\ " ! 150: You can use the ! 151: .B reply ! 152: command to ! 153: set up a response to a message, sending it back to the ! 154: person who it was from. ! 155: Text you then type in, up to an end-of-file, ! 156: defines the contents of the message. ! 157: While you are composing a message, ! 158: .I mail ! 159: treats lines beginning with the character `~' specially. ! 160: For instance, typing ``~m'' (alone on a line) will place a copy ! 161: of the current message into the response right shifting it by a tabstop. ! 162: Other escapes will set up subject fields, add and delete recipients ! 163: to the message and allow you to escape to an editor to revise the ! 164: message or to a shell to run some commands. (These options ! 165: are given in the summary below.) ! 166: .PP ! 167: .I "Ending a mail processing session.\ " ! 168: You can end a ! 169: .I mail ! 170: session with the ! 171: .B quit ! 172: (\fBq\fR) ! 173: command. ! 174: Messages which have been examined go to your ! 175: .I mbox ! 176: file unless they have been deleted in which case they are discarded. ! 177: Unexamined messages go back to the post office. ! 178: The ! 179: .B \-f ! 180: option causes ! 181: .I mail ! 182: to read in the contents of your ! 183: .I mbox ! 184: (or the specified file) ! 185: for processing; when you ! 186: .BR quit , ! 187: .I mail ! 188: writes undeleted messages back to this file. ! 189: The ! 190: .B \-u ! 191: flag is a short way of doing ! 192: "mail ! 193: .B \-f ! 194: /usr/spool/mail/user". ! 195: .PP ! 196: .I "Personal and systemwide distribution lists.\ " ! 197: It is also possible to create a personal distribution lists so that, ! 198: for instance, you can send mail to ``cohorts'' and have it go ! 199: to a group of people. ! 200: Such lists can be defined by placing a line like ! 201: .IP ! 202: alias cohorts bill ozalp jkf mark kridle@ucbcory ! 203: .PP ! 204: in the file \&.mailrc in your home directory. ! 205: The current list of such aliases can be displayed with the ! 206: .B alias ! 207: .B (a) ! 208: command in ! 209: .IR mail . ! 210: System wide distribution lists can be created by editing ! 211: /usr/lib/aliases, see ! 212: .IR aliases (5) ! 213: and ! 214: .IR sendmail (8); ! 215: these are kept in a different syntax. ! 216: In mail you send, personal aliases will be expanded in mail sent ! 217: to others so that they will be able to \fBreply\fR to the recipients. ! 218: System wide \fIaliases\fR are not expanded when the mail is sent, ! 219: but any reply returned to the machine will have the system wide ! 220: alias expanded as all mail goes through ! 221: .IR sendmail . ! 222: .PP ! 223: .I "Network mail (ARPA, UUCP, Berknet)\ " ! 224: See ! 225: .IR mailaddr(7) ! 226: for a description of network addresses. ! 227: .PP ! 228: .I Mail ! 229: has a number of options which can be set in the ! 230: .I \&.mailrc ! 231: file to alter its behavior; thus ``set askcc'' enables the ``askcc'' ! 232: feature. (These options are summarized below.) ! 233: .SH SUMMARY ! 234: (Adapted from the `Mail Reference Manual') ! 235: .PP ! 236: Each command is typed on a line by itself, and may take arguments ! 237: following the command word. The command need not be typed in its ! 238: entirety \- the first command which matches the typed prefix is used. ! 239: For commands which take message lists as arguments, if no message ! 240: list is given, then the next message forward which satisfies the ! 241: command's requirements is used. If there are no messages forward of ! 242: the current message, the search proceeds backwards, and if there are no ! 243: good messages at all, ! 244: .I mail ! 245: types ``No applicable messages'' and ! 246: aborts the command. ! 247: .TP 12n ! 248: .B \- ! 249: Goes to the previous message and prints it out. If given a numeric ! 250: argument ! 251: .IR n , ! 252: goes to the ! 253: .IR n -th ! 254: previous message and prints it. ! 255: .TP ! 256: .B ? ! 257: Prints a brief summary of commands. ! 258: .TP ! 259: .B ! ! 260: Executes the \s-2UNIX\s0 shell command which follows. ! 261: .TP ! 262: .B Print ! 263: (\fBP\fR) ! 264: Like ! 265: .B print ! 266: but also prints out ignored header fields. See also ! 267: .B print ! 268: , ! 269: .B ignore ! 270: and ! 271: .B retain. ! 272: .TP ! 273: .B Reply ! 274: (\fBR\fR) ! 275: Reply to originator. Does not reply to other ! 276: recipients of the original message. ! 277: .TP ! 278: .B Type ! 279: (\fBT\fR) ! 280: Identical to the ! 281: .B Print ! 282: command. ! 283: .TP ! 284: .B alias ! 285: (\fBa\fR) With no arguments, prints out all currently-defined aliases. With one ! 286: argument, prints out that alias. With more than one argument, creates ! 287: an new or changes an on old alias. ! 288: .TP ! 289: .B alternates ! 290: (\fBalt\fR) ! 291: The ! 292: .B alternates ! 293: command is useful if you have accounts on several machines. ! 294: It can be used to inform ! 295: .I mail ! 296: that the listed addresses are really you. When you ! 297: .B reply ! 298: to messages, ! 299: .I mail ! 300: will not send a copy of the message to any of the addresses ! 301: listed on the ! 302: .I alternates ! 303: list. If the ! 304: .B alternates ! 305: command is given with no argument, the current set of alternate ! 306: names is displayed. ! 307: .TP ! 308: .B chdir ! 309: (\fBc\fR) Changes the user's working directory to that specified, if given. If ! 310: no directory is given, then changes to the user's login directory. ! 311: .TP ! 312: .B copy ! 313: (\fBco\fR) ! 314: The ! 315: .B copy ! 316: command does the same thing that ! 317: .B save ! 318: does, except that it does not mark the messages it ! 319: is used on for deletion when you quit. ! 320: .TP ! 321: .B delete ! 322: (\fBd\fR) Takes a list of messages as argument and marks them all as deleted. ! 323: Deleted messages will not be saved in ! 324: .IR mbox , ! 325: nor will they be available for most other commands. ! 326: .TP ! 327: .B dp ! 328: (also \fBdt\fR) Deletes the current message and prints the next message. ! 329: If there is no next message, ! 330: .I mail ! 331: says ``at EOF.'' ! 332: .TP ! 333: .B edit ! 334: (\fBe\fR) Takes a list of messages and points the text editor at each one in ! 335: turn. On return from the editor, the message is read back in. ! 336: .TP ! 337: .B exit ! 338: (\fBex\fR or \fBx\fR) Effects an immediate return to the Shell without ! 339: modifying the user's system mailbox, his ! 340: .I mbox ! 341: file, or his edit file in ! 342: .BR \-f . ! 343: .TP ! 344: .B file ! 345: (\fBfi\fR) ! 346: The same as ! 347: .BR folder . ! 348: .TP ! 349: .B folders ! 350: List the names of the folders in your folder directory. ! 351: .TP ! 352: .B folder ! 353: (\fBfo\fR) ! 354: The ! 355: .B folder ! 356: command switches to a new mail file or folder. With no ! 357: arguments, it tells you which file you are currently reading. ! 358: If you give it an argument, it will write out changes (such ! 359: as deletions) you have made in the current file and read in ! 360: the new file. Some special conventions are recognized for ! 361: the name. # means the previous file, % means your system ! 362: mailbox, %user means user's system mailbox, & means ! 363: your \~/mbox file, and +folder means a file in your folder ! 364: directory. ! 365: .TP ! 366: .B from ! 367: (\fBf\fR) Takes a list of messages and prints their message headers. ! 368: .TP ! 369: .B headers ! 370: (\fBh\fR) Lists the current range of headers, which is an 18 message group. If ! 371: a ``+'' argument is given, then the next 18 message group is printed, and if ! 372: a ``\-'' argument is given, the previous 18 message group is printed. ! 373: .TP ! 374: .B help ! 375: A synonym for ? ! 376: .TP ! 377: .B hold ! 378: (\fBho\fR, also \fBpreserve\fR) Takes a message list and marks each ! 379: message therein to be saved in the ! 380: user's system mailbox instead of in ! 381: .IR mbox . ! 382: Does not override the ! 383: .B delete ! 384: command. ! 385: .TP ! 386: .B ignore ! 387: .B N.B.: ! 388: .I Ignore ! 389: has been superseded by ! 390: .I retain. ! 391: .br ! 392: Add the list of header fields named to the ! 393: .IR "ignored list" . ! 394: Header fields in the ignore list are not printed ! 395: on your terminal when you print a message. This ! 396: command is very handy for suppression of certain machine-generated ! 397: header fields. The ! 398: .B Type ! 399: and ! 400: .B Print ! 401: commands can be used to print a message in its entirety, including ! 402: ignored fields. If ! 403: .B ignore ! 404: is executed with no arguments, it lists the current set of ! 405: ignored fields. ! 406: .TP ! 407: .B mail ! 408: (\fBm\fR) Takes as argument login names and distribution group names and sends ! 409: mail to those people. ! 410: .TP ! 411: .B mbox ! 412: Indicate that a list of messages be sent to ! 413: .I mbox ! 414: in your home directory when you quit. This is the default ! 415: action for messages if you do ! 416: .I not ! 417: have the ! 418: .I hold ! 419: option set. ! 420: .TP ! 421: .B next ! 422: (\fBn\fR like \fB+\fR or CR) Goes to the next message in sequence and types it. ! 423: With an argument list, types the next matching message. ! 424: .TP ! 425: .B preserve ! 426: (\fBpre\fR) ! 427: A synonym for ! 428: .BR hold . ! 429: .TP ! 430: .B print ! 431: (\fBp\fR) ! 432: Takes a message list and types out each message on the user's terminal. ! 433: .TP ! 434: .B quit ! 435: (\fBq\fR) Terminates the session, saving all undeleted, unsaved messages in ! 436: the user's ! 437: .I mbox ! 438: file in his login directory, preserving all messages marked with ! 439: .B hold ! 440: or ! 441: .B preserve ! 442: or never referenced ! 443: in his system mailbox, and removing all other messages from his system ! 444: mailbox. If new mail has arrived during the session, the message ! 445: ``You have new mail'' is given. If given while editing a ! 446: mailbox file with the ! 447: .B \-f ! 448: flag, then the edit file is rewritten. A return to the Shell is ! 449: effected, unless the rewrite of edit file fails, in which case the user ! 450: can escape with the ! 451: .B exit ! 452: command. ! 453: .TP ! 454: .B reply ! 455: (\fBr\fR) ! 456: Takes a message list and sends mail to the sender and all ! 457: recipients of the specified message. ! 458: The default message must not be deleted. ! 459: .TP ! 460: .B respond ! 461: A synonym for ! 462: .BR reply . ! 463: .TP ! 464: .B retain ! 465: Add the list of header fields named to the ! 466: .IR "retained list" . ! 467: Only the header fields in the retain list ! 468: are shown on your terminal when you print a message. ! 469: All other header fields are suppressed. ! 470: The ! 471: .B Type ! 472: and ! 473: .B Print ! 474: commands can be used to print a message in its entirety. ! 475: If ! 476: .B retain ! 477: is executed with no arguments, it lists the current set of ! 478: retained fields. ! 479: .TP ! 480: .B save ! 481: (\fBs\fR) Takes a message list and a filename and appends each message in ! 482: turn to the end of the file. The filename in quotes, followed by the line ! 483: count and character count is echoed on the user's terminal. ! 484: .TP ! 485: .B set ! 486: (\fBse\fR) With no arguments, prints all variable values. Otherwise, sets ! 487: option. Arguments are of the form ! 488: ``option=value'' ! 489: (no space before or after =) or ! 490: ``option.'' ! 491: .TP ! 492: .B shell ! 493: (\fBsh\fR) Invokes an interactive version of the shell. ! 494: .TP ! 495: .B size ! 496: Takes a message list and prints out the size in characters of each ! 497: message. ! 498: .TP ! 499: .B source ! 500: (\fBso\fR) ! 501: The ! 502: .B source ! 503: command reads ! 504: .I mail ! 505: commands from a file. ! 506: .TP ! 507: .B top ! 508: Takes a message list and prints the top few lines of each. The number of ! 509: lines printed is controlled by the variable ! 510: .B toplines ! 511: and defaults to five. ! 512: .TP ! 513: .B type ! 514: (\fBt\fR) A synonym for ! 515: .BR print . ! 516: .TP ! 517: .B unalias ! 518: Takes a list of names defined by ! 519: .B alias ! 520: commands and discards the remembered groups of users. The group names ! 521: no longer have any significance. ! 522: .TP ! 523: .B undelete ! 524: (\fBu\fR) Takes a message list and marks each message as ! 525: .I not ! 526: being deleted. ! 527: .TP ! 528: .B unread ! 529: (\fBU\fR) Takes a message list and marks each message as ! 530: .I not ! 531: having been read. ! 532: .TP ! 533: .B unset ! 534: Takes a list of option names and discards their remembered values; ! 535: the inverse of ! 536: .BR set . ! 537: .TP ! 538: .B visual ! 539: (\fBv\fR) Takes a message list and invokes the display editor on each message. ! 540: .TP ! 541: .B write ! 542: (\fBw\fR) Similar to ! 543: .BR save , ! 544: except that ! 545: .I only ! 546: the message body (\fIwithout\fP the header) is saved. ! 547: Extremely useful for such tasks as sending and receiving source ! 548: program text over the message system. ! 549: .TP ! 550: .B xit ! 551: (\fBx\fR) A synonym for ! 552: .BR exit . ! 553: .TP ! 554: .B z ! 555: .I Mail ! 556: presents message headers in windowfuls as described under the ! 557: .B headers ! 558: command. You can move ! 559: .IR mail 's ! 560: attention forward to the next window with the ! 561: .B z ! 562: command. Also, you can move to the previous window by using ! 563: .BR z\- . ! 564: .PP ! 565: Here is a summary of the tilde escapes, ! 566: which are used when composing messages to perform ! 567: special functions. Tilde escapes are only recognized at the beginning ! 568: of lines. The name ! 569: ``tilde\ escape'' ! 570: is somewhat of a misnomer since the actual escape character can be set ! 571: by the option ! 572: .B escape. ! 573: .TP 12n ! 574: .BR ~! command ! 575: Execute the indicated shell command, then return to the message. ! 576: .TP ! 577: \fB~b\fR name ... ! 578: Add the given names to the list of carbon copy recipients but do not make ! 579: the names visible in the Cc: line ("blind" carbon copy). ! 580: .TP ! 581: \fB~c\fR name ... ! 582: Add the given names to the list of carbon copy recipients. ! 583: .TP ! 584: .B ~d ! 585: Read the file ``dead.letter'' from your home directory into the message. ! 586: .TP ! 587: .B ~e ! 588: Invoke the text editor on the message collected so far.
