+.Sh NAME
+.Nm biff
+.Nd "be notified if mail arrives and who it is from"
+.Sh SYNOPSIS
+.Nm
+.Op Cm n | y | b
+.Sh DESCRIPTION
+The
+.Nm
+utility informs the system whether you want to be notified on your terminal
+when mail arrives.
+.Pp
+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
+.Nm
+runs on.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Cm n
+Disable notification.
+.It Cm y
+Enable header notification.
+.It Cm b
+Enable bell notification.
+.El
+.Pp
+When header notification is enabled, the header and first few lines of
+the message will be printed on your terminal whenever mail arrives.
+A
+.Dq Li biff y
+command is often included in the file
+.Pa \&.login
+or
+.Pa \&.profile
+to be executed at each login.
+.Pp
+When bell notification is enabled, only two bell characters
+.Tn ( ASCII
+\\007)
+will be printed on your terminal whenever mail arrives.
+.Pp
+If no arguments are given,
+.Nm
+displays the present notification status of the terminal to the
+standard output.
+.Pp
+The
+.Nm
+utility operates asynchronously.
+For synchronous notification use the
+.Ev MAIL
+variable of
+.Xr sh 1
+or the
+.Ev mail
+variable of
+.Xr csh 1 .
+.Sh DIAGNOSTICS
+The
+.Nm
+utility exits with one of the following values:
+.Bl -tag -width indent
+.It 0
+Notification is enabled.
+.It 1
+Notification is disabled.
+.It >1
+An error occurred.
+.El
+.Sh COMPATIBILITY
+Previous versions of the
+.Nm
+utility affected the terminal attached to standard error without first
+trying the standard input or output devices.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr mail 1 ,
+.Xr sh 1 ,
+.Xr comsat 8
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.0 .
+It was named after the dog of Heidi Stettner.
+He died
+in August 1993, at 15.
