mail - send or receive mail among users SYNOPSIS
mail person ... mail [ -r ] [ -q ] [ -p ] [ -f file ] DESCRIPTION
Mail with no argument prints a user's mail, message-by-message, in last-in, first-out order; the optional argument -r causes first-in, first-out order. If the -p flag is given, the mail is printed with no questions asked; otherwise, for each message, mail reads a line from the standard input to direct disposition of the message. newline Go on to next message. d Delete message and go on to the next. p Print message again. - Go back to previous message. s [ file ] ... Save the message in the named files (`mbox' default). w [ file ] ... Save the message, without a header, in the named files (`mbox' default). m [ person ] ... Mail the message to the named persons (yourself is default). EOT (control-D) Put unexamined mail back in the mailbox and stop. q Same as EOT. x Exit, without changing the mailbox file. !command Escape to the Shell to do command. ? Print a command summary. An interrupt stops the printing of the current letter. The optional argument -q causes mail to exit after interrupts without changing the mailbox. When persons are named, mail takes the standard input up to an end-of-file (or a line with just `.') and adds it to each person's `mail' file. The message is preceded by the sender's name and a postmark. Lines that look like postmarks are prepended with `>'. A person is usually a user name recognized by login(1). To denote a recipient on a remote system, prefix person by the system name and exclamation mark (see uucp(1)). The -f option causes the named file, e.g. `mbox', to be printed as if it were the mail file. Each user owns his own mailbox, which is by default generally readable but not writable. The command does not delete an empty mailbox nor change its mode, so a user may make it unreadable if desired. When a user logs in he is informed of the presence of mail. FILES

There is a locking mechanism intended to prevent two senders from accessing the same mailbox, but it is not perfect and races are possible. MAIL(1)

mail, binmail - Sends and displays messages SYNOPSIS
Reading Mail mail [-epq] [-bhr] [-f file] binmail [-epq] [-bhr] [-f file] Sending Mail mail [-d] [-r name] [-h N] user... [< file] binmail [-d] [-r name] [-h N] user... [< file] STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: mail: XCU5.0 binmail: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Reading Mail You can use the following options when invoking the mail command to read mail: Does not display any messages. This option causes mail to return an exit value of 0 (zero) if the user has mail and an exit value of 1 if the user has no mail. Saves mail to and reads mail from file instead of the default mail file, /usr/spool/mail/user. Displays mail without prompting for a disposition code. This option does not delete, copy, or forward any messages. Causes mail to exit when you press the Interrupt key sequence. Normally, pressing the Interrupt key sequence stops only the message being displayed. (In this case, the next message sometimes does not display until you enter the p subcom- mand.) Displays mail in first-in, first-out order. The default is last-in, first-out. Alternate and obsolete form of the -b option. If -r is the first option specified and more arguments follow, send mail mode is assumed. Alternate and obsolete form of the -b option. If -h is the first option specified and more arguments follow, send mail mode is assumed. Sending Mail You can use the following options when invoking the mail command to send mail: Sets the hop count to N. The hop count is incremented every time the mail is processed. When it reaches a limit, the mail is returned with an error message, the victim of an aliasing loop. If you do not specify this option, received lines in the message are counted. Sets the name of the From: user field (that is, the sender of the mail). The -r option can only be used by trusted users (normally root, daemon, and network) or if the person you are trying to become is the same as the person you are. Informs binmail to actually deliver the mail instead of passing it off to the sendmail program for deliv- ery. DESCRIPTION
The mail command writes to standard output all stored mail addressed to your login name, one message at a time, or sends a mail message to another user or users. Another name for the mail command is binmail. Following each message, mail prompts you with a ? question mark. Press <Return> to display the current mail message, or enter one of the subcommands that control the disposition of the message. When sending mail, you specify users, and then mail reads a message from standard input until you press the End-of-File key sequence or enter a line containing only a . (dot). It prefixes this message with the sender's name and the date and time of the message (its postmark) and adds this message to the file /usr/spool/mail/user for each user specified on the command line. Usually, user is a name recognized by the login command. If the system does not recognize one or more of the specified users or if mail is interrupted during input, mail saves messages in the file $HOME/dead.letter to allow for editing and resending. The action of mail can be modified in two ways by manipulating /usr/spool/mail/user: The default permission assignment for other users is read-only. If you change this permission assignment to read/write or to All Permissions Denied, the system preserves the file, even when it is empty, in order to maintain the desired permissions; you will not be able to remove the file. You can edit the file to contain the following as its first line: Forward to person This causes all messages sent to user to be sent to person instead. The Forward to feature is especially useful for sending all of a person's mail to a particular machine in a network environment. To specify a recipient on a remote system, prefix the system name and an ! (exclamation mark) to user. See the uucp command for a detailed discussion of how to address remote systems. Also see mailx and sendmail for other network connections. Tru64 UNIX provides locking for the mailbox files. The style of locking used depends on how it is set in the rc.config.common file. For more information, see the Network Administration manual. Subcommands The following subcommands control message disposition. Displays the next mail message. Displays the previous message. Deletes the cur- rent message and displays the next message. Displays the current message again. Saves the message in file instead of in the default mail file $HOME/mbox. Saves the message, without its postmark, in file instead of in the default mail file, $HOME/mbox. Forwards the current message to users. If the forward was successful, deletes that message and then displays the next message. Writes any mail not yet deleted to /usr/spool/mail/user and exits. Pressing the End-of-File key sequence has the same effect. Exit, leaving the mail file unchanged. Runs the specified command. Displays a subcommand summary. Displays a subcommand summary. NOTES
The mail utility is marked LEGACY in XCU Issue 5. The binmail program is not RFC 822 compliant. This affects messages that begin withlines that look like header lines. Header lines begin with a string followed by a colon (:) (such as those found in the /etc/passwd file). Use mailx command to send such messages, or make sure the message is preceded by a blank line. EXIT STATUS
For information about exit values, see the OPTIONS section. EXAMPLES
To display your mail, enter: mail After the most recent message is displayed, a ? (question mark) indicates that mail is waiting for one of the subcommands explained previously (+, -, d, p, and so on). Enter help or an * (asterisk) to list the subcommands available. If the End-of-File key sequence is <Ctrl-d>, you send mail to other users by entering: mail tom rachel Do not forget the meeting tomorrow at 9:30. <Ctrl- d> In this example, the system mails the message Do not forget the meeting tomorrow at 9:30. to the users tom and rachel. The End-of- File key sequence (in this case, <Ctrl-d>) indicates the end of the message, but it is not sent with the text. To send a file to another user, enter: mail fran < proposal This command sends the contents of the file proposal to fran. To save a message to the default mail file, enter: mail This command displays each message mailed to you. Press <Return> after the ? prompt until the desired message is displayed. When the appropriate message is displayed, enter: s The message is saved in the default mail file, $HOME/mbox. To save a message to a specific file, enter: mail This command displays each message mailed to you. Press <Return> after the ? prompt until the desired message is displayed. When the appropriate message is displayed, enter: s mycopy This command saves the message in a file named mycopy in the current directory, rather than in the default mail file. FILES
