.Sh DESCRIPTION
|
|
.Nm 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.
|
|
.Pp
|
|
.Nm Msgs
|
|
is normally invoked each time you login, by placing it in the file
|
|
.Pa .login
|
|
(or
|
|
.Pa .profile
|
|
if you use
|
|
.Xr 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:
|
|
.Bl -tag -width Fl
|
|
.It Fl y
|
|
Type the rest of the message.
|
|
.It Ic RETURN
|
|
Synonym for y.
|
|
.It Fl n
|
|
Skip this message
|
|
and go on to the next message.
|
|
.It Fl
|
|
Redisplay the last message.
|
|
.It Fl q
|
|
Drop out of
|
|
.Nm msgs ;
|
|
the next time
|
|
.Nm
|
|
will pick up where it last left off.
|
|
.It Fl 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''.
|
|
.It Fl m
|
|
A copy of the specified message is placed in a temporary
|
|
mailbox and
|
|
.Xr mail 1
|
|
is invoked on that mailbox.
|
|
Both `m' and `s' accept a numeric argument in place of the `\-'.
|
|
.El
|
|
.Pp
|
|
.Nm Msgs
|
|
keeps track of the next message you will see by a number in the file
|
|
.Pa \&.msgsrc
|
|
in your home directory.
|
|
In the directory
|
|
.Pa /var/msgs
|
|
it keeps a set of files whose names are the (sequential) numbers
|
|
of the messages they represent.
|
|
The file
|
|
.Pa /var/msgs/bounds
|
|
shows the low and high number of the messages in the directory
|
|
so that
|
|
.Nm
|
|
can quickly determine if there are no messages for you.
|
|
If the contents of
|
|
.Pa bounds
|
|
is incorrect it can be fixed by removing it;
|
|
.Nm
|
|
will make a new
|
|
.Pa bounds
|
|
file the next time it is run with the
|
|
.Fl s
|
|
option.
|
|
If
|
|
.Nm
|
|
is run with any option other than
|
|
.Fl s ,
|
|
an error will be displayed if
|
|
.Pa /var/msgs/bounds
|
|
does not exist.
|
|
.Pp
|
|
The
|
|
.Fl s
|
|
option is used for setting up the posting of messages. The line
|
|
.Pp
|
|
.Dl msgs: \&"\&| /usr/bin/msgs \-s\&"
|
|
.Pp
|
|
should be included in
|
|
.Pa /etc/aliases
|
|
(see
|
|
.Xr newaliases 1 )
|
|
to enable posting of messages.
|
|
.Pp
|
|
The
|
|
.Fl c
|
|
option is used for performing cleanup on
|
|
.Pa /var/msgs .
|
|
A shell script entry to run
|
|
.Nm
|
|
with the
|
|
.Fl c
|
|
option should be placed in
|
|
.Pa /etc/periodic/daily
|
|
(see
|
|
.Xr 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.
|
|
.Pp
|
|
Options when reading messages include:
|
|
.Bl -tag -width Fl
|
|
.It Fl f
|
|
Do not say ``No new messages.''.
|
|
This is useful in a
|
|
.Pa .login
|
|
file since this is often the case here.
|
|
.It Fl q
|
|
Queries whether there are messages, printing
|
|
``There are new messages.'' if there are.
|
|
The command ``msgs \-q'' is often used in login scripts.
|
|
.It Fl h
|
|
Print the first part of messages only.
|
|
.It Fl l
|
|
Option causes only locally originated messages to be reported.
|
|
.It Ar num
|
|
A message number can be given
|
|
on the command line, causing
|
|
.Nm
|
|
to start at the specified message rather than at the next message
|
|
indicated by your
|
|
.Pa \&.msgsrc
|
|
file.
|
|
Thus
|
|
.Pp
|
|
.Dl msgs \-h 1
|
|
.Pp
|
|
prints the first part of all messages.
|
|
.It Ar \-number
|
|
Start
|
|
.Ar number
|
|
messages back from the one indicated in the
|
|
.Pa \&.msgsrc
|
|
file, useful for reviews of recent messages.
|
|
.It Fl p
|
|
Pipe long messages through
|
|
.Xr more 1 .
|
|
.El
|
|
.Pp
|
|
Within
|
|
.Nm
|
|
you can also go to any specific message by typing its number when
|
|
.Nm
|
|
requests input as to what to do.
|
|
.Sh ENVIRONMENT
|
|
.Nm Msgs
|
|
uses the
|
|
.Ev HOME
|
|
and
|
|
.Ev TERM
|
|
environment variables for the default home directory and
|
|
terminal type.
