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 The .Nm utility 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 ; 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 The .Nm utility 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/mail/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. You must be the superuser to use this option. .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 Cause 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 The .Nm utility uses the .Ev HOME and .Ev TERM environment variables for the default home directory and terminal type. .Sh FILES .Bl -tag -width /var/msgs/* -compact .It Pa /var/msgs/* database .It Pa ~/.msgsrc number of next message to be presented .El .Sh SEE ALSO .Xr mail 1 , .Xr more 1 , .Xr aliases 5 , .Xr periodic 8 .Sh HISTORY The .Nm command appeared in .Bx 3.0 .
