biff(1)                 (BSD Compatibility Package)                 biff(1)


   NAME
         biff - give notice of incoming mail messages

   SYNOPSIS
         /usr/ucb/biff [ y | n ]

   DESCRIPTION
         biff turns mail notification on or off for the terminal session.
         With no arguments, biff displays the current notification status for
         the terminal.

         The y option allows mail notification for the terminal.  The n option
         disables notification for the terminal.

         If notification is allowed, the terminal rings the bell and displays
         the header and the first few lines of each arriving mail message.
         biff operates asynchronously.  For synchronized notices, use the MAIL
         variable of sh(1) or the mail variable of csh(1).

         A `biff y' command can be included in your ~/.login or ~/.profile
         file for execution when you log in.

   FILES
         ~/.login
         ~/.profile
