      NAME
           mail - interactive message processing system

      SYNTAX
           Mail [options] [name...]
           mail [options] [name...]
           mailx [options] [name...]

      DESCRIPTION
           The command mail provides a comfortable, flexible
           environment for sending and receiving messages
           electronically.  When reading mail, mailx provides commands
           to facilitate saving, deleting, and responding to messages.
           When sending mail, mailx allows editing, reviewing and other
           modification of the message as it is entered.  The mail
           command is identical to mailx as provided with AT&T System
           5; the mailx command was derived from and is very similar to
           the 4.2 command Mail.

           Incoming mail is stored in a standard file for each user,
           called the system mailbox for that user.  When mailx is
           called to read messages, the mailbox is the default place to
           find them.  As messages are read, they are marked to be
           moved to a secondary file for storage, unless specific
           action is taken, so that the messages need not be seen
           again.  This secondary file is called the mbox and is
           normally located in the user's HOME directory (see "MBOX"
           (ENVIRONMENT VARIABLES) for a description of this file).
           Messages remain in this file until deliberately removed.

           On the command line, options start with a dash (-) and any
           other arguments are taken to be destinations (recipients).
           If no recipients are specified, mailx will attempt to read
           messages from the mailbox.  Command line options are:


                -d            Turn on debugging output.  Neither
                              particularly interesting nor recommended.
                -e            Test for presence of mail.  Mail prints
                              nothing and exits with a successful
                              return code if there is mail to read.
                -f [filename] Read messages from filename instead of
                              mailbox.  If no filename is specified,
                              the mbox is used.
                -F            Record the message in a file named after
                              the first recipient.  Overrides the
                              "record" variable, if set (see
                              ENVIRONMENT VARIABLES).
                -h number     The number of network "hops" made so far.
                              This is provided for network software to
                              avoid infinite delivery loops.
                -H            Print header summary only.

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



                -i            Ignore interrupts.  See also "ignore"
                              (ENVIRONMENT VARIABLES).
                -n            Do not initialize from the system default
                              mail.rc file.
                -N            Do not print initial header summary.
                -r address    Pass address to network delivery
                              software.  All tilde commands are
                              disabled.
                -s subject    Set the Subject header field to subject.
                -u user       Read user's mailbox.  This is only
                              effective if user's mailbox is not read
                              protected.
                -U            Convert uucp style addresses to internet
                              standards.  Overrides the "conv"
                              environment variable.


           When reading mail, mailx is in command mode.  A header
           summary of the first several messages is displayed, followed
           by a prompt indicating mailx can accept regular commands
           (see COMMANDS below).  When sending mail, mailx 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,
           mailx 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 TILDE ESCAPES for a
           summary of these commands.

           At any time, the behavior of mailx is governed by a set of
           environment variables.  These are flags and valued
           parameters which are set and cleared via the set and unset
           commands.  See ENVIRONMENT VARIABLES below for a summary of
           these parameters.

           Recipients listed on the command line may be of three types:
           login names, shell commands, or alias groups.  Login names
           may be any network address, including mixed network
           addressing.  If the recipient name begins with ``escape
           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 lp(1) for recording outgoing mail on paper.
           Alias groups are set by the alias command (see COMMANDS
           below) and are lists of recipients of any type.

           Regular commands are of the form

                          [ command ] [ msglist ] [ arguments ]

           If no command is specified in command mode, print is
           assumed.  In input mode, commands are recognized by the

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



           escape character, and lines not treated as commands are
           taken as input for the message.

           Each message is assigned a sequential number, and there is,
           at any time, the notion of a 'current' message, marked by a
           '>' in the header summary.  Many commands take an optional
           list of messages (msglist) to operate on, which defaults to
           the current message.  A msglist is a list of message
           specifications separated by spaces, which may include:

                n       Message number n.
                .       The current message.
                ^       The first undeleted message.
                $       The last message.
                *       All messages.
                n-m     An inclusive range of message numbers.
                user    All messages from user.
                /string All messages with string in the subject line
                        (case ignored).
                :c      All messages of type c, where c is one of:
                             d    deleted messages
                             n    new messages
                             o    old messages
                             r    read messages
                             u    unread messages
                        Note that the context of the command determines
                        whether this type of message specification
                        makes sense.

           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
           sh(1)).  Special characters are recognized by certain
           commands and are documented with the commands below.

           At start-up time, mailx reads commands from a system-wide
           file (/usr/lib/mail/mail.rc) to initialize certain
           parameters, then from a private start-up file
           ($HOME/.mailrc) for personalized variables.  Most regular
           commands are legal inside start-up files, the most common
           use being 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, preserve,
           reply, Reply, shell, and visual.  Any errors in the start-up
           file cause the remaining lines in the file to be ignored.

      COMMANDS
           The following is a complete list of mailx commands:

           !shell-command
                Escape to the shell.  See "SHELL" (ENVIRONMENT
                VARIABLES).

           # comment
                Null command (comment).  This may be useful in .mailrc
                files.

           =
                Print the current message number.

           ?
                Prints a summary of commands.

           alias alias name ...
           group alias name ...
                Declare an alias for the given names.  The names will
                be substituted when alias is used as a recipient.
                Useful in the .mailrc file.

           alternates name ...
                Declares a list of alternate names for your login.
                When responding to a message, these names are removed
                from the list of recipients for the response.  With no
                arguments, alternates prints the current list of
                alternate names.  See also "allnet" (ENVIRONMENT
                VARIABLES).

           cd [directory]
           chdir [directory]
                Change directory.  If directory is not specified, $HOME
                is used.

           copy [filename]
           copy [msglist] filename
                Copy messages to the file without marking the messages
                as saved.  Otherwise equivalent to the save command.

           Copy [msglist]
                Save the specified messages in a file whose name is
                derived from the author of the message to be saved,
                without marking the messages as saved.  Otherwise
                equivalent to the Save command.

           delete [msglist]
                Delete messages from the mailbox.  If "autoprint" is
                set, the next message after the last one deleted is
                printed (see ENVIRONMENT VARIABLES).

           discard [header-field ...]
           ignore [header-field ...]
                Suppresses printing of the specified header fields when
                displaying messages on the screen.  Examples of header
                fields to ignore are "status" and "cc." The fields are
                included when the message is saved.  The Print and Type
                commands override this command.

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



           dp [msglist]
           dt [msglist]
                Delete the specified messages from the mailbox and
                print the next message after the last one deleted.
                Roughly equivalent to a delete command followed by a
                print command.

           echo string ...
                Echo the given strings (like echo(1)).

           edit [msglist]
                Edit the given messages.  The messages are placed in a
                temporary file and the "EDITOR" variable is used to get
                the name of the editor (see ENVIRONMENT VARIABLES).
                Default editor is ed(1).

           exit
           xit
                Exit from mailx, without changing the mailbox.  No
                messages are saved in the mbox (see also quit).

           file [filename]
           folder [filename]
                Quit from the current file of messages and read in the
                specified file.  Several special characters are
                recognized when used as file names, with the following
                substitutions:
                        %     the current mailbox.
                        %user the mailbox for user.
                        #     the previous file.
                        &     the current mbox.
                Default file is the current mailbox.

           folders
                Print the names of the files in the directory set by
                the "folder" variable (see ENVIRONMENT VARIABLES).

           followup [message]
                Respond to a message, recording the response in a file
                whose name is derived from the author of the message.
                Overrides the "record" variable, if set.  See also the
                Followup, Save, and Copy commands and "outfolder"
                (ENVIRONMENT VARIABLES).

           Followup [msglist]
                Respond to the first message in the msglist, sending
                the message to the author of each message in the
                msglist.  The subject line is taken from the first
                message and the response is recorded in a file whose
                name is derived from the author of the first message.
                See also the followup, Save, and Copy commands and
                "outfolder" (ENVIRONMENT VARIABLES).

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



           from [msglist]
                Prints the header summary for the specified messages.

           group alias name ...
           alias alias name ...
                Declare an alias for the given names.  The names will
                be substituted when alias is used as a recipient.
                Useful in the .mailrc file.

           headers [message]
                Prints the page of headers along with the specified
                message.  The "screen" variable sets the number of
                headers per page (see ENVIRONMENT VARIABLES).  See also
                the z command.

           help
                Prints a summary of commands.

           hold [msglist]
           preserve [msglist]
                Holds the specified messages in the mailbox.

           if s|r
           mail-commands
           else
           mail-commands
           endif
                Conditional execution.  An s following the if statement
                will execute the following mail-commands, up to an else
                or endif, if the program is in send mode.  The r
                following the if statement causes the mail-commands to
                be executed only in receive mode.  Useful in the
                .mailrc file.

           ignore header-field ...
           discard header-field ...
                Suppresses printing of the specified header fields when
                displaying messages on the screen.  Examples of header
                fields to ignore are "status" and "cc." All fields are
                included when the message is saved.  The Print and Type
                commands override this command.

           list
                Prints all commands available.  No explanation is
                given.

           mail name ...
                Mail a message to the specified users.

           mbox [msglist]
                Arrange for the given messages to end up in the
                standard mbox save file when mailx terminates normally.

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



                See "MBOX" (ENVIRONMENT VARIABLES) for a description of
                this file.  See also the exit and quit commands.

           next [message]
                Go to next message matching message.  A msglist may be
                specified, but in this case the first valid message in
                the list is the only one used.  This is useful for
                jumping to the next message from a specific user, since
                the name would be taken as a command in the absence of
                a real command.  See the discussion of msglists above
                for a description of possible message specifications.

           pipe [msglist] [shell-command]
           | [msglist] [shell-command]
                Pipe the message through the given shell-command.  The
                message is treated as if it were read.  If no arguments
                are given, the current message is piped through the
                command specified by the value of the "cmd" variable.
                If the "page" variable is set, a form feed character is
                inserted after each message (see ENVIRONMENT

           preserve [msglist]
           hold [msglist]
                Preserve the specified messages in the mailbox.

           Print [msglist]
           Type [msglist]
                Print the specified messages on the screen, including
                all header fields.  Overrides suppression of fields by
                the ignore command.

           print [msglist]
           type [msglist]
                Print the specified messages.  If "crt" is set, the
                messages longer than the number of lines specified by
                the "crt" variable are paged through the command
                specified by the "PAGER" variable.  The default command
                is pg(1) (see ENVIRONMENT VARIABLES).

           quit
                Exit from mailx, storing messages that were read in
                mbox and unread messages in the mailbox.  Messages that
                have been explicitly saved in a file are deleted.

           Reply [msglist]
           Respond [msglist]
                Send a response to the author of each message in the
                msglist.  The subject line is taken from the first
                message.  If "record" is set to a filename, the
                response is saved at the end of that file (see
                ENVIRONMENT VARIABLES).

           respond [message]
                Reply to the specified message, including all other
                recipients of the message.  If "record" is set to a
                filename, the response is saved at the end of that file
                (see ENVIRONMENT VARIABLES).

           Save [msglist]
                Save the specified messages in a file whose name is
                derived from the author of the first message.  The name
                of the file is taken to be the author's name with all
                network addressing stripped off.  See also the Copy,
                followup, and Followup commands and "outfolder"
                (ENVIRONMENT VARIABLES).

           save [filename]
           save [msglist] filename
                Save the specified messages in the given file.  The
                file is created if it does not exist.  The message is
                deleted from the mailbox when mailx terminates unless
                "keepsave" is set (see also ENVIRONMENT VARIABLES and
                the exit and quit commands).

           set
           set name
           set name=string
           set name=number
                Define a variable called name.  The variable may be
                given a null, string, or numeric value.  Set by itself
                prints all defined variables and their values.  See
                ENVIRONMENT VARIABLES for detailed descriptions of the
                mailx variables.

           shell
                Invoke an interactive shell (see also "SHELL"
                (ENVIRONMENT VARIABLES)).

           size [msglist]
                Print the size in characters of the specified messages.

           source filename
                Read commands from the given file and return to command
                mode.

           top [msglist]
                Print the top few lines of the specified messages.  If
                the "toplines" variable is set, it is taken as the
                number of lines to print (see ENVIRONMENT VARIABLES).
                The default is 5.

           touch [msglist]
                Touch the specified messages.  If any message in
                msglist is not specifically saved in a file, it will be
                placed in the mbox upon normal termination.  See exit
                and quit.

           Type [msglist]
           Print [msglist]
                Print the specified messages on the screen, including

           undelete [msglist]
                Restore the specified deleted messages.  Will only
                restore messages deleted in the current mail session.
                If "autoprint" is set, the last message of those
                restored is printed (see ENVIRONMENT VARIABLES).

           unset name ...
                Causes the specified variables to be erased.  If the
                variable was imported from the execution environment
                (i.e., a shell variable) then it cannot be erased.

           version
                Prints the current version and release date.

           visual [msglist]
                Edit the given messages with a screen editor.  The
                messages are placed in a temporary file and the
                "VISUAL" variable is used to get the name of the editor
                (see ENVIRONMENT VARIABLES).  The default editor is
                vi(1).

           write [msglist] filename
                Write the given messages on the specified file, minus

                command.  If the shell-command returns a successful
                exit status, the output of the command replaces the
                message.

      ENVIRONMENT VARIABLES
           The following are environment variables taken from the
           execution environment and are not alterable within mailx.

           HOME=directory
                The user's base of operations.

           MAILRC=filename
                The name of the start-up file.  Default is
                $HOME/.mailrc.

           The following variables are internal mailx variables.  They
           may be imported from the execution environment or set via
           the set command at any time.  The unset command may be used
           to erase variables.

           allnet
                All network names whose last component (login name)
                match are treated as identical.  This causes the
                msglist message specifications to behave similarly.
                Default is noallnet.  See also the alternates command
                and the "metoo" variable.

           append
                Upon termination, append messages to the end of the
                mbox file instead of prepending them.  Default is
                noappend.

           askcc
                Prompt for the Cc list after message is entered.
                Default is noaskcc.

           asksub
                Prompt for subject if it is not specified on the
                command line with the -s option.  Enabled by default.

           autoprint
                Enable automatic printing of messages after delete and
                undelete commands.  Default is noautoprint.

           bang
                Enable the special-casing of exclamation points (!) in
                shell escape command lines as in vi(1).  Default is
                nobang.

           cmd=shell-command
                Set the default command for the pipe command.  No
                default value.

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



           conv=conversion
                Convert uucp addresses to the specified address style.
                The only valid conversion now is internet, which
                requires a mail delivery program conforming to the
                RFC822 standard for electronic mail addressing.
                Conversion is disabled by default.  See also "sendmail"
                and the -U command line option.

           crt=number
                Pipe messages having more than number lines through the
                command specified by the value of the "PAGER" variable
                (pg(1) by default).  Disabled by default.

           DEAD=filename
                The name of the file in which partial letters are saved
                in the event of untimely interrupt or delivery errors.
                Default is $HOME/dead.letter.

           debug
                Enable verbose diagnostics for debugging.  Messages are
                not delivered.  Default is nodebug.

           dot
                Take a period on a line by itself during input from a
                terminal as end-of-file.  Default is nodot.

           EDITOR=shell-command
                The command to run when the edit or ~e command is used.
                Default is ed(1).

           escape=c
                Substitute c for the ~ escape character.

           folder=directory
                The directory for saving standard mail files.  User
                specified file names beginning with a plus (+) are
                expanded by preceding the filename with this directory
                name to obtain the real filename.  If directory does
                not start with a slash (/), $HOME is prepended to it.
                In order to use the plus (+) construct on a mailx
                command line, "folder" must be an exported sh
                environment variable.  There is no default for the
                "folder" variable.  See also "outfolder" below.

           header
                Enable printing of the header summary when entering
                mailx.  Enabled by default.

           hold
                Preserve all messages that are read in the mailbox
                instead of putting them in the standard mbox save file.
                Default is nohold.

      MAIL(1)                     (UNIX 5.2)                    MAIL(1)



           ignore
                Ignore interrupts while entering messages.  Handy for
                noisy dial-up lines.  Default is noignore.

           ignoreeof
                Ignore end-of-file during message input.  Input must be
                terminated by a period (.) on a line by itself or by
                the ~. command.  Default is noignoreeof.  See also
                "dot" above.

           keep
                When the mailbox is empty, truncate it to zero length
                instead of removing it.  Disabled by default.

           keepsave
                Keep messages that have been saved in other files in
                the mailbox instead of deleting them.  Default is
                nokeepsave.

           MBOX=filename
                The name of the file to save messages which have been
                read.  The xit command overrides this function, as does
                saving the message explicitly in another file.  Default
                is $HOME/mbox.

           metoo
                If your login appears as a recipient, do not delete it
                from the list.  Default is nometoo.

           LISTER=shell-command
                The command (and options) to use when listing the
                contents of the "folder" directory.  The default is
                ls(1).

           onehop
                When responding to a message that was originally sent
                to several recipients, the other recipient addresses
                are normally forced to be relative to the originating
                author's machine for the response.  This flag disables
                alteration of the recipients' addresses, improving
                efficiency in a network where all machines can send
                directly to all other machines (i.e., one hop away).

           outfolder
                Causes the files used to record outgoing messages to be
                located in the directory specified by the "folder"
                variable unless the pathname is absolute.  Default is

      BUGS
           Where shell-command is shown as valid, arguments are not
           always allowed.  Experimentation is recommended.

           Internal variables imported from the execution environment
           cannot be unset.

           The full internet addressing is not fully supported by
           mailx.  The new standards need some time to settle down.

           Attempts to send a message having a line consisting only of
           a ``.'' are treated as the end of the message by binmail(1)
           (the local mail delivery program).

           Error messages name the program mailx.

           Help files and rmmail are contained in the /usr/lib/mailx
           directory.
