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).
