msgs - system messages and junk mail program
msgs [ -fhlpqr ] [[-]number]
msgs -c [ days ]
Msgs 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.
Msgs 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 Type the rest of the message.
RETURN Synonym for y.
n Skip this message and go on to the next message.
- Redisplay the last message.
q Drop out of msgs ; the next time msgs will pick up
where it last left off.
s Append the current message to the file ``Messages''
in the current directory; `s-' will save the
previously displayed message. A `s' or `s-' may be
followed by a space and a file name to receive the
message replacing the default ``Messages''.
m A copy of the specified message is placed in a
temporary mailbox and mail(1) is invoked on that
p The specified message is piped through $PAGER or, if
$PAGER is not defined, more(1).
The commands `m', `p' and `s' all accept a numeric argument
in place of the `-'.
Msgs 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.
The -s option is used for setting up the posting of
messages. The line
msgs: "| /usr/bin/msgs -s"
should be included in /etc/aliases (see newaliases(1)) to
enable posting of messages.
The -c option is used for performing cleanup on /var/msgs.
An entry with the -c option should be placed in /etc/crontab
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.
Options when reading messages include:
f Do not to say ``No new messages.''. This is useful
in a .login file since this is often the case here.
q Queries whether there are messages, printing ``There
are new messages.'' if there are. The command ``msgs
-q'' is often used in login scripts.
h Print the first part of messages only.
r Disables the ability to save messages or enter the
mailer. It is assumed that $PAGER is set to
l Option causes only locally originated messages to be
[-]num A message number can be given on the command line,
causing msgs to start at the specified message rather
than at the next message indicated by your .msgsrc
msgs -h 1
prints the first part of all messages.
Start number messages back from the one indicated in
the .msgsrc file, useful for reviews of recent
p Pipe long messages through $PAGER or, if $PAGER is
not defined, more(1).
Within msgs you can also go to any specific message by
typing its number when msgs requests input as to what to do.
Msgs uses the HOME and TERM environment variables for the
default home directory and terminal type.
~/.msgsrc number of next message to be presented
aliases(5), crontab(5), mail(1), more(1)
