biff(1)            UNIX System V(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.
