MAIL(1)                   BSD General Commands Manual                  MAIL(1)

     mail - send and receive mail

     mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr...
     mail [-iInNv] -f [name]
     mail [-iInNv] [-u user]

     Mail is an intelligent mail processing system, which has a command syntax
     reminiscent of ed(1) with lines replaced by messages.

     -v    Verbose mode.  The details of delivery are displayed on the user's

     -i    Ignore tty interrupt signals.  This is particularly useful when
           using mail on noisy phone lines.

     -I    Forces mail to run in interactive mode even when input isn't a ter-
           minal.  In particular, the '~' special character when sending mail
           is only active in interactive mode.

     -n    Inhibits reading /etc/mail.rc upon startup.

     -N    Inhibits the initial display of message headers when reading mail
           or editing a mail folder.

     -s    Specify subject on command line (only the first argument after the
           -s flag is used as a subject; be careful to quote subjects contain-
           ing spaces.)

     -c    Send carbon copies to list of users.

     -b    Send blind carbon copies to list.  List should be a comma-separated
           list of names.

     -f    Read in the contents of your mbox (or the specified file) for pro-
           cessing; when you quit, mail writes undeleted messages back to this

     -u    Is equivalent to:

                 mail -f /var/spool/mail/user

   Sending mail
     To send a message to one or more people, mail can be invoked with argu-
     ments which are the names of people to whom the mail will be sent.  You
     are then expected to type in your message, followed by an 'control-D' at
     the beginning of a line.  The section below Replying to or originating
     mail, describes some features of mail available to help you compose your

   Reading mail
     In normal usage mail is given no arguments and checks your mail out of
     the post office, then prints out a one line header of each message found.
     The current message is initially the first message (numbered 1) and can
     be printed using the print command (which can be abbreviated 'p').  You
     can move among the messages much as you move between lines in ed(1), with
     the commands '+' and '-' moving backwards and forwards, and simple num-

   Disposing of mail.
     After examining a message you can delete 'd') the message or reply 'r')
     to it.  Deletion causes the mail program to forget about the message.
     This is not irreversible; the message can be undeleted 'u') by giving its
     number, or the mail session can be aborted by giving the exit 'x') com-
     mand.  Deleted messages will, however, usually disappear never to be seen

   Specifying messages
     Commands such as print and delete can be given a list of message numbers
     as arguments to apply to a number of messages at once.  Thus ``delete 1
     2'' deletes messages 1 and 2, while ``delete 1-5'' deletes messages 1
     through 5.  The special name '*' addresses all messages, and '$'
     addresses the last message; thus the command top which prints the first
     few lines of a message could be used in ``top *'' to print the first few
     lines of all messages.

   Replying to or originating mail.
     You can use the reply command to set up a response to a message, sending
     it back to the person who it was from.  Text you then type in, up to an
     end-of-file, defines the contents of the message.  While you are compos-
     ing a message, mail treats lines beginning with the character '~' spe-
     cially.  For instance, typing '~m' (alone on a line) will place a copy of
     the current message into the response right shifting it by a tabstop (see
     indentprefix variable, below).  Other escapes will set up subject fields,
     add and delete recipients to the message and allow you to escape to an
     editor to revise the message or to a shell to run some commands.  (These
     options are given in the summary below.)

   Ending a mail processing session.
     You can end a mail session with the quit 'q') command.  Messages which
     have been examined go to your mbox file unless they have been deleted in
     which case they are discarded.  Unexamined messages go back to the post
     office.  (See the -f option above).

   Personal and systemwide distribution lists.
     It is also possible to create a personal distribution lists so that, for
     instance, you can send mail to ``cohorts'' and have it go to a group of
     people.  Such lists can be defined by placing a line like

           alias cohorts bill ozalp jkf mark kridle@ucbcory

     in the file .mailrc in your home directory.  The current list of such
     aliases can be displayed with the alias command in mail.  System wide
     distribution lists can be created by editing /etc/aliases, see aliases(5)
     and sendmail(8); these are kept in a different syntax.  In mail you send,
     personal aliases will be expanded in mail sent to others so that they
     will be able to reply to the recipients.  System wide aliases are not
     expanded when the mail is sent, but any reply returned to the machine
     will have the system wide alias expanded as all mail goes through

   Network mail (ARPA, UUCP, Berknet)
     See mailaddr(7) for a description of network addresses.

     Mail has a number of options which can be set in the .mailrc file to
     alter its behavior; thus ``set askcc'' enables the askcc feature.  (These
     options are summarized below.)

     (Adapted from the `Mail Reference Manual')

     Each command is typed on a line by itself, and may take arguments follow-
     ing the command word.  The command need not be typed in its entirety -
     the first command which matches the typed prefix is used.  For commands
     which take message lists as arguments, if no message list is given, then
     the next message forward which satisfies the command's requirements is
     used.  If there are no messages forward of the current message, the
     search proceeds backwards, and if there are no good messages at all, mail
     types ``applicable messages'' and aborts the command.

     -       Print out the preceding message.  If given a numeric argument n,
             goes to the n'th previous message and prints it.

     ?       Prints a brief summary of commands.

     !       Executes the shell (see sh(1) and csh(1)) command which follows.

     Print   (P) Like print but also prints out ignored header fields.  See
             also print, ignore and retain.

     Reply   (R) Reply to originator.  Does not reply to other recipients of
             the original message.

     Type    (T) Identical to the Print command.

     alias   (a) With no arguments, prints out all currently-defined aliases.
             With one argument, prints out that alias.  With more than one
             argument, creates a new alias or changes an old one.

             (alt) The alternates command is useful if you have accounts on
             several machines.  It can be used to inform mail that the listed
             addresses are really you.  When you reply to messages, mail will
             not send a copy of the message to any of the addresses listed on
             the alternates list.  If the alternates command is given with no
             argument, the current set of alternate names is displayed.

     chdir   (c) Changes the user's working directory to that specified, if
             given.  If no directory is given, then changes to the user's
             login directory.

     copy    (co) The copy command does the same thing that save does, except
             that it does not mark the messages it is used on for deletion
             when you quit.

     delete  (d) Takes a list of messages as argument and marks them all as
             deleted.  Deleted messages will not be saved in mbox, nor will
             they be available for most other commands.

     dp      (also dt) Deletes the current message and prints the next mes-
             sage.  If there is no next message, mail says ``at EOF''.

     edit    (e) Takes a list of messages and points the text editor at each
             one in turn.  On return from the editor, the message is read back

     exit    (ex or x) Effects an immediate return to the Shell without modi-
             fying the user's system mailbox, his mbox file, or his edit file
             in -f.

     file    (fi) The same as folder.

             List the names of the folders in your folder directory.

     folder  (fo) The folder command switches to a new mail file or folder.
             With no arguments, it tells you which file you are currently
             reading.  If you give it an argument, it will write out changes
             (such as deletions) you have made in the current file and read in
             the new file.  Some special conventions are recognized for the
             name.  # means the previous file, % means your system mailbox,
             %user means user's system mailbox, & means your mbox file, and
             +folder means a file in your folder directory.

     from    (f) Takes a list of messages and prints their message headers.

             (h) Lists the current range of headers, which is an 18-message
             group.  If a '+' argument is given, then the next 18-message
             group is printed, and if a '-' argument is given, the previous
             18-message group is printed.

     help    A synonym for ?

     hold    (ho, also preserve) Takes a message list and marks each message
             therein to be saved in the user's system mailbox instead of in
             mbox.  Does not override the delete command.

     ignore  Add the list of header fields named to the ignored list.  Header
             fields in the ignore list are not printed on your terminal when
             you print a message.  This command is very handy for suppression
             of certain machine-generated header fields.  The Type and Print
             commands can be used to print a message in its entirety, includ-
             ing ignored fields.  If ignore is executed with no arguments, it
             lists the current set of ignored fields.

     mail    (m) Takes as argument login names and distribution group names
             and sends mail to those people.

     mbox    Indicate that a list of messages be sent to mbox in your home
             directory when you quit.  This is the default action for messages
             if you do not have the hold option set.

     next    (n) like + or CR) Goes to the next message in sequence and types
             it.  With an argument list, types the next matching message.

             (pre) A synonym for hold.

     print   (p) Takes a message list and types out each message on the user's

     quit    (q) Terminates the session, saving all undeleted, unsaved mes-
             sages in the user's mbox file in his login directory, preserving
             all messages marked with hold or preserve or never referenced in
             his system mailbox, and removing all other messages from his sys-
             tem mailbox.  If new mail has arrived during the session, the
             message ``You have new mail'' is given.  If given while editing a
             mailbox file with the -f flag, then the edit file is rewritten.
             A return to the Shell is effected, unless the rewrite of edit
             file fails, in which case the user can escape with the exit com-

     reply   (r) Takes a message list and sends mail to the sender and all
             recipients of the specified message.  The default message must
             not be deleted.

             A synonym for reply.

     retain  Add the list of header fields named to the retained list Only the
             header fields in the retain list are shown on your terminal when
             you print a message.  All other header fields are suppressed.
             The Type and Print commands can be used to print a message in its
             entirety.  If retain is executed with no arguments, it lists the
             current set of retained fields.

     save    (s) Takes a message list and a filename and appends each message
             in turn to the end of the file.  The filename in quotes, followed
             by the line count and character count is echoed on the user's

     set     (se) With no arguments, prints all variable values.  Otherwise,
             sets option.  Arguments are of the form option=value (no space
             before or after =) or option.  Quotation marks may be placed
             around any part of the assignment statement to quote blanks or
             tabs, i.e.  ``set indentprefix="->"''

             Saveignore is to save what ignore is to print and type.  Header
             fields thus marked are filtered out when saving a message by save
             or when automatically saving to mbox.

             Saveretain is to save what retain is to print and type.  Header
             fields thus marked are the only ones saved with a message when
             saving by save or when automatically saving to mbox.  Saveretain
             overrides saveignore.

     shell   (sh) Invokes an interactive version of the shell.

     size    Takes a message list and prints out the size in characters of
             each message.

     source  The source command reads commands from a file.

     top     Takes a message list and prints the top few lines of each.  The
             number of lines printed is controlled by the variable toplines
             and defaults to five.

     type    (t) A synonym for print.

             Takes a list of names defined by alias commands and discards the
             remembered groups of users.  The group names no longer have any

             (u) Takes a message list and marks each message as not being

     unread  (U) Takes a message list and marks each message as not having
             been read.

     unset   Takes a list of option names and discards their remembered val-
             ues; the inverse of set.

     visual  (v) Takes a message list and invokes the display editor on each

     write   (w) Similar to save, except that only the message body (without)
             the header) is saved.  Extremely useful for such tasks as sending
             and receiving source program text over the message system.

     xit     (x) A synonym for exit.

     z       Mail presents message headers in windowfuls as described under
             the headers command.  You can move mail's attention forward to
             the next window with the z command.  Also, you can move to the
             previous window by using z-.

     Here is a summary of the tilde escapes, which are used when composing
     messages to perform special functions.  Tilde escapes are only recognized
     at the beginning of lines.  The name ``tilde escape'' is somewhat of a
     misnomer since the actual escape character can be set by the option

             Execute the indicated shell command, then return to the message.

     ~bname ...
             Add the given names to the list of carbon copy recipients but do
             not make the names visible in the Cc: line ("blind" carbon copy).

     ~cname ...
             Add the given names to the list of carbon copy recipients.

     ~d      Read the file ``dead.letter'' from your home directory into the

     ~e      Invoke the text editor on the message collected so far.  After
             the editing session is finished, you may continue appending text
             to the message.

             Read the named messages into the message being sent.  If no mes-
             sages are specified, read in the current message.  Message head-
             ers currently being ignored (by the ignore or retain command) are
             not included.

             Identical to ~f, except all message headers are included.

     ~h      Edit the message header fields by typing each one in turn and
             allowing the user to append text to the end or modify the field
             by using the current terminal erase and kill characters.

             Read the named messages into the message being sent, indented by
             a tab or by the value of indentprefix.  If no messages are speci-
             fied, read the current message.  Message headers currently being
             ignored (by the ignore or retain command) are not included.

             Identical to ~m, except all message headers are included.

     ~p      Print out the message collected so far, prefaced by the message
             header fields.

     ~q      Abort the message being sent, copying the message to
             ``dead.letter'' in your home directory if save is set.

             Read the named file into the message.

             Cause the named string to become the current subject field.

     ~tname ...
             Add the given names to the direct recipient list.

     ~v      Invoke an alternate editor (defined by the VISUAL option) on the
             message collected so far.  Usually, the alternate editor will be
             a screen editor.  After you quit the editor, you may resume
             appending text to the end of your message.

             Write the message onto the named file.

             Pipe the message through the command as a filter.  If the command
             gives no output or terminates abnormally, retain the original
             text of the message.  The command fmt(1) is often used as command
             to rejustify the message.

             Execute the given mail command.  Not all commands, however, are

             Insert the string of text in the message prefaced by a single ~.
             If you have changed the escape character, then you should double
             that character in order to send it.

   Mail Options
     Options are controlled via set and unset commands.  Options may be either
     binary, in which case it is only significant to see whether they are set
     or not; or string, in which case the actual value is of interest.  The
     binary options include the following:

     append  Causes messages saved in mbox to be appended to the end rather
             than prepended.  This should always be set (perhaps in

     ask, asksub
             Causes mail to prompt you for the subject of each message you
             send.  If you respond with simply a newline, no subject field
             will be sent.

     askcc   Causes you to be prompted for additional carbon copy recipients
             at the end of each message.  Responding with a newline indicates
             your satisfaction with the current list.

     askbcc  Causes you to be prompted for additional blind carbon copy recip-
             ients at the end of each message.  Responding with a newline
             indicates your satisfaction with the current list.

             Causes the delete command to behave like dp - thus, after delet-
             ing a message, the next one will be typed automatically.

     debug   Setting the binary option debug is the same as specifying -d on
             the command line and causes mail to output all sorts of informa-
             tion useful for debugging mail.

     dot     The binary option dot causes mail to interpret a period alone on
             a line as the terminator of a message you are sending.

     hold    This option is used to hold messages in the system mailbox by

     ignore  Causes interrupt signals from your terminal to be ignored and
             echoed as @'s.

             An option related to dot is ignoreeof which makes mail refuse to
             accept a control-d as the end of a message.  Ignoreeof also
             applies to mail command mode.

     metoo   Usually, when a group is expanded that contains the sender, the
             sender is removed from the expansion.  Setting this option causes
             the sender to be included in the group.

             Setting the option noheader is the same as giving the -N flag on
             the command line.

     nosave  Normally, when you abort a message with two RUBOUT (erase or
             delete) mail copies the partial letter to the file
             ``dead.letter'' in your home directory.  Setting the binary
             option nosave prevents this.

             Reverses the sense of reply and Reply commands.

     quiet   Suppresses the printing of the version when first invoked.

             If this option is set, then a message-list specifier in the form
             ``/x:y'' will expand to all messages containing the substring
             ``y'' in the header field ``x''.  The string search is case

             Setting the option verbose is the same as using the -v flag on
             the command line.  When mail runs in verbose mode, the actual
             delivery of messages is displayed on the user's terminal.

   Option String Values
     EDITOR        Pathname of the text editor to use in the edit command and
                   ~e escape.  If not defined, then a default editor is used.

     LISTER        Pathname of the directory lister to use in the folders com-
                   mand.  Default is /bin/ls.

     PAGER         Pathname of the program to use in the more command or when
                   crt variable is set.  The default paginator more(1) is used
                   if this option is not defined.

     SHELL         Pathname of the shell to use in the ! command and the ~!
                   escape.  A default shell is used if this option is not

     VISUAL        Pathname of the text editor to use in the visual command
                   and ~v escape.

     crt           The valued option crt is used as a threshold to determine
                   how long a message must be before PAGER is used to read it.
                   If crt is set without a value, then the height of the ter-
                   minal screen stored in the system is used to compute the
                   threshold (see stty(1)).

     escape        If defined, the first character of this option gives the
                   character to use in the place of ~ to denote escapes.

     folder        The name of the directory to use for storing folders of
                   messages.  If this name begins with a `/', mail considers
                   it to be an absolute pathname; otherwise, the folder direc-
                   tory is found relative to your home directory.
