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: and Subject: header lines and
  up to	the first five lines of	the message are	displayed. The total display
  is 560 characters, or	seven lines terminated by newline characters, which-
  ever occurs first.

  The biff y command is	often included in the $HOME/.login or $HOME/.profile
  file to be executed each time	you log	in.

  The biff command operates asynchronously. For	synchronous notification, use
  the MAIL variable of sh or ksh, or the mail variable of csh.

	    biff

       file:
	    biff y
