biff - be notified if mail arrives and who it is from
biff [y | n]
biff informs the system whether you want to be notified when
during the current terminal session.
The options are as follows:
n Disables notification.
y Enables notification.
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).
csh(1), mail(1), sh(1), comsat(8)
The biff command appeared in 4.0BSD. "Biff" was Heidi Stettner's dog.
He died in August 1993, at 15.
