NAME
  biff - Notifies users when mail arrives

SYNOPSIS

  biff [y | n]

DESCRIPTION

  The biff command informs the system whether you want to be notified when
  mail arrives during the current terminal session.  The following command
  enables notification:

       biff y


  The following command disables notification:

       biff n


  When mail notification is enabled, the From:, To:, Date:, and Subject:
  header lines and the first seven lines or 560 characters of the message are
  displayed.  The biff y command is often included in the $HOME/.login or

  use the MAIL variable of sh or ksh, or the mail variable of csh.
