The msgs
utility is used to read system
messages. These messages are sent by mailing to the login `msgs' and should
be short pieces of information which are suitable to be read once by most
users of the system.
The msgs
utility is normally invoked each
time you login, by placing it in the file .login (or
.profile if you use
sh(1)). It will then prompt
you with the source and subject of each new message. If there is no subject
line, the first few non-blank lines of the message will be displayed. If
there is more to the message, you will be told how long it is and asked
whether you wish to see the rest of the message. The possible responses
are:
-y
RETURN
-n
-
-q
msgs
; the next time
msgs
will pick up where it last left off.-s
-m
The msgs
utility keeps track of the next
message you will see by a number in the file .msgsrc
in your home directory. In the directory /var/msgs
it keeps a set of files whose names are the (sequential) numbers of the
messages they represent. The file /var/msgs/bounds
shows the low and high number of the messages in the directory so that
msgs
can quickly determine if there are no messages
for you. If the contents of bounds is incorrect it
can be fixed by removing it; msgs
will make a new
bounds file the next time it is run with the
-s
option. If msgs
is run
with any option other than -s
, an error will be
displayed if /var/msgs/bounds does not exist.
The -s
option is used for setting up the
posting of messages. The line
msgs: "| /usr/bin/msgs
-s"
should be included in /etc/mail/aliases (see newaliases(1)) to enable posting of messages.
The -c
option is used for performing
cleanup on /var/msgs. A shell script entry to run
msgs
with the -c
option
should be placed in /etc/periodic/daily (see
periodic(8)) to run
every night. This will remove all messages over 21 days old. A different
expiration may be specified on the command line to override the default. You
must be the superuser to use this option.
Options when reading messages include:
-f
-q
-h
-l
msgs
to start at the specified message rather than
at the next message indicated by your .msgsrc
file. Thus
msgs -h 1
prints the first part of all messages.
-p
Within msgs
you can also go to any
specific message by typing its number when msgs
requests input as to what to do.
The msgs
utility uses the
HOME
and TERM
environment
variables for the default home directory and terminal type.
The msgs
command appeared in
3.0BSD.
