NAME

biff − asynchronous notification of mail

USAGE

biff [ y | n ]

DESCRIPTION

The biff command tells the system whether you want to be notified of incoming mail while you are logged in.  The command

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 displayed in a window whenever mail arrives.  Most users include a biff command line in their .login or .profile file, so that biff is set at log-in time. 

The biff program operates asynchronously. For synchronous notification use the MAIL variable of sh (1) or the mail variable of csh (1).
