biff(1)                                                   biff(1)



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

     SYNOPSIS
          biff [choice]

     DESCRIPTION
          biff informs the system whether you want to be notified when
          mail arrives during the current terminal session.  choice
          can be either y or n (yes or no) so the command

               biff y

          enables notification; the command:

               biff n

          disables it.  With no argument, biff prints the current no-
          tification states.  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), csh(1), or ksh(1).
