Name
comsat - biff server
Syntax
/etc/comsat
Description
The command is the server process which receives reports of incoming mail and notifies users if they have requested this service. The com-
mand is invoked by when it detects an incoming packet on the datagram port associated with the ``biff'' service specification. For further
information, see The command reads the packet, which is a one line message of the form:
user@mailbox-offset
If the user specified is logged in to the system and the associated terminal has the owner execute bit turned on (by a ``biff y''), the
offset is used as a seek offset into the appropriate mailbox file and the first 7 lines or 560 characters of the message are printed on the
user's terminal. Lines which appear to be part of the message header other than the From:, To:, Date:, or Subject: lines are not included
in the displayed message.
Restrictions
The message header filtering is prone to error.
Files
