VACATION(1) BSD Reference Manual VACATION(1)
vacation - return ``I am not here'' indication
vacation -i [-r interval]
vacation [-a alias] login
Vacation returns a message to the sender of a message telling them that
you are currently not reading your mail. The intended use is in a
.forward file. For example, your .forward file might have:
\eric, "|/usr/bin/vacation -a allman eric"
which would send messages to you (assuming your login name was eric) and
reply to any messages for ``eric'' or ``allman''.
Handle messages for alias in the same manner as those received
for the user's login name.
-i Initialize the vacation database files. It should be used before
you modify your .forward file.
-r Set the reply interval to interval days. The default is one
week. An interval of ``0'' means that a reply is sent to each
message, and an interval of ``infinite'' (actually, any non-
numeric character) will never send more than one reply. It
should be noted that intervals of ``0'' are quite dangerous, as
it allows mailers to get into ``I am on vacation'' loops.
No message will be sent unless login (or an alias supplied using the -a
option) is part of either the ``To:'' or ``Cc:'' headers of the mail. No
messages from ``???-REQUEST'', ``Postmaster'', ``UUCP'', ``MAILER'', or
``MAILER-DAEMON'' will be replied to (where these strings are case insen-
sitive) nor is a notification sent if a ``Precedence: bulk'' or
``Precedence: junk'' line is included in the mail headers. The people
who have sent you messages are maintained as a db(3) database in the file
.vacation.db in your home directory.
Vacation expects a file .vacation.msg, in your home directory, containing
a message to be sent back to each sender. It should be an entire message
(including headers). For example, it might contain:
From: ericATCS.EDU (Eric Allman)
Subject: I am on vacation
Delivered-By-The-Graces-Of: The Vacation program
I am on vacation until July 22. If you have something urgent,
please contact Keith Bostic <bosticATCS.EDU>.
Vacation reads the first line from the standard input for a UNIX ``From''
line to determine the sender. Sendmail(8) includes this ``From'' line
Fatal errors, such as calling vacation with incorrect arguments, or with
non-existent logins, are logged in the system log file, using syslog(8).
