NAME
     biff - be notified if mail arrives and who it is from
SYNOPSIS
     biff [n | y]
DESCRIPTION
     biff informs the system whether you want to be notified when mail arrives
     during the current terminal session.
     The options are as follows:
     n       Disables notification.
     y       Enables notification.
     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 exe-
     cuted at each login.
     biff operates asynchronously.  For synchronous notification use the MAIL
     variable of sh(1) or the mail variable of csh(1).
