binmail(1) General Commands Manual binmail(1) Name binmail - send or receive mail among users Syntax /bin/mail [+] [-i] [person...] /bin/mail [+] [-i] -f file Description This is the old version 7 UNIX system mail program. The default command is described in and its binary is in the directory The program is still used to actually deliver a mail message into the users system-wide mailbox ( ), however, the reading of these messages has been replaced with the program Do not remove from your system. The command with no argument prints a user's mail, message-by-message, in last-in, first-out order; the optional argument + displays the mail messages in first-in, first-out order. For each message, it reads a line from the standard input to direct the disposition of the message. Issue the following commands from the program prompt: <CR> 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. !command Escape to the Shell to do command. * Print a command summary. An interrupt normally terminates the command; the mail file is unchanged. When persons are named, 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 To denote a recipient on a remote system, prefix person by the system name and exclamation mark. For further information, see The program sends a message to the screen that there is mail when the user logs in. When is used to deliver mail, (usually calls to do this), a mailbox is created for the user in the directory if it doesn't already exist. The mailbox is created with the mode 700 so that only its owner can access it. In addition, the directory has the mode 777 with the sticky bit set. The mode is 777 so that other mail programs, notably can create the appropriate lock files to prevent another process from writ- ing to the mailbox at the same time. The sticky bit set on the directory prevents one user from unlinking another user's mailbox. Options -f Displays mail messages contained in the specified file (next argument) in place of your mailbox file. -i Notifies mail to continue after interrupts. Restrictions Race conditions sometimes result in a failure to remove a lock file.
