comsat |
comsat is the server process which receives reports of
incoming mail and notifies users if they have requested this service.
comsat receives messages on a datagram port associated
with the “biff” service specification (see
services(5) and
inetd(8)). The one line messages are of the
form:
user@mailbox-offsetIf 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.
comsat command appeared in
4.2BSD.
Users should be notified of mail which arrives on other machines than the one to which they are currently logged in.
The notification should appear in a separate window so it does not mess up the screen.
