    BIFF(1)             UNIX Programmer's Manual		  BIFF(1)

    NAME
         biff - be notified if mail arrives and who it is from

    SYNOPSIS
         biff [ yn ]

    DESCRIPTION
         Biff informs the system whether you want to be notified when
         mail arrives during the current terminal session.	The com-
         mand

    	  biff y

         enables notification; the command

    	  biff n

         disables it.  When mail notification is enabled, the header
         and first few lines of the message will be printed on your
         screen whenever mail arrives.  A ``biff y'' command is often
         included in the file .login or .profile to be executed at
         each login.

         Biff operates asynchronously.  For synchronous notification
         use the MAIL variable of sh(1) or the mail variable of
         csh(1).
