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
