biff |
[n | y] |
DESCRIPTION
biff informs the system whether you want to be notified
when mail arrives during the current terminal session.
Options supported by biff:
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.
When no arguments are present, biff
displays the current notification status to the standard output.
biff operates asynchronously. For
synchronous notification use the MAIL variable of
sh(1)
or the mail variable of
csh(1).
