biff -- be notified if mail arrives and who it is from SYNOPSIS
biff [n | y | b] DESCRIPTION
The biff utility informs the system whether you want to be notified on your terminal when mail arrives. Affected is the first terminal associated with the standard input, standard output or standard error file descriptor, in that order. Thus, it is possible to use the redirection facilities of a shell to toggle the notification for other terminals than the one biff runs on. The following options are available: n Disable notification. y Enable header notification. b Enable bell notification. When header notification is enabled, the header and first few lines of the message will be printed on your terminal whenever mail arrives. A ``biff y'' command is often included in the file .login or .profile to be executed at each login. When bell notification is enabled, only two bell characters (ASCII 07) will be printed on your terminal whenever mail arrives. If no arguments are given, biff displays the present notification status of the terminal to the standard output. The biff utility operates asynchronously. For synchronous notification use the MAIL variable of sh(1) or the mail variable of csh(1). DIAGNOSTICS
The biff utility exits with one of the following values: 0 Notification is enabled. 1 Notification is disabled. >1 An error occurred. COMPATIBILITY
Previous versions of the biff utility affected the terminal attached to standard error without first trying the standard input or output devices. SEE ALSO

rcvtty - report new mail SYNOPSIS
/usr/lib/mh/rcvtty [command] [-form formatfile] [-format string] [-width columns] [-bell | -nobell] [-newline | -nonewline] [-biff] [-ver- sion] [-help] DESCRIPTION
The rcvtty can be used to report new mail. It is used primarily in conjunction with mail filtering agents such as slocal or procmail. The rcvtty program executes the named command with the message as its standard input, and writes the resulting output on your terminal. Alternately, if no command is specified (or is bogus), then rcvtty will instead write a one-line scan listing. The default output format of this scan listing may be overridden by using either the -form formatfile or -format string option, similar to the equivalent options for scan and inc. See mh-format(5) for details. A newline is output before the message output, and the terminal bell is rung after the output. The -nonewline and -nobell options will inhibit these functions. The switch -width columns may be given to specify the width of the scan line. The default is to use the width of the terminal. In addition to the standard format escapes described in mh-format(5), rcvtty also recognizes the following additional component escapes: Escape Returns Description body string the (compressed) first part of the body dtimenow date the current date folder string the name of the current folder By default, rcvtty will send its output to every terminal on the local machine that is owned by current user, and that has given write per- mission as granted by the command mesg(1). If the option -biff is given, then rcvtty will obey the notification status set by the command biff(1) instead. FILES
