Enables or disables mail notification during the current session.
biff [ y | n ]
The biff command informs the system whether you want to be notified when mail arrives. When mail notification is enabled, From and Subject header lines and the first 7 lines or 560 characters of a message are displayed on the screen when mail arrives. Notification, specified by the biff y command, is often included in the $HOME/.login or $HOME/.profile file to be executed each time the user logs in. The biff n command disables notification.
Note: In addition to y and n, you can use yes and no to enable and disable mail notification.
The biff command operates asynchronously. To receive notification when mail arrives, ensure:
For synchronous notification, use the MAIL variable of either the ksh command, bsh command, or the csh command.
