|COMSAT(8)||System Manager's Manual||COMSAT(8)|
comsatis the server process which receives reports of incoming mail and notifies users if they have requested this service.
comsatreceives 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:
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.
comsatcommand 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.
