biff - be notified if mail arrives and who it is from SYNOPSIS


Biff informs the system whether you want to be notified when mail arrives during the current terminal session.

Options supported by biff


Disables notification.yEnables notification.When mail notification is enabled, the header and first fewlines of the message will be printed on your screen whenevermail arrives. A ``biff y'' command is often included in the file .login or .profile to be executed at each login.

Biff operates asynchronously via the comsat(8) service. If that service is not enabled, biff will not do anything. In that case, or for synchronous notification, use the MAIL variable of sh(1) or the mail variable of csh(1).


csh(1), mail(1), sh(1), comsat(8) HISTORY

The biff command appeared in 4.0 BSD . BUGS

su(1), and biff don't seem to get on too well. This is prob- ably due to the tty still being owned by the person using su. This can result in ``Permission denied'' messages when attempting to change the biff status of your session.

Please report bugs to including diffs/patches, compiler error logs or as complete a bug report as is possible.
