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, whichever 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.

EXAMPLES

       To  display  the current setting, enter: biff To be notified during the current terminal session whenever mail arrives, enter the following
       in your $HOME/.login or $HOME/.profile file: biff y
