Ok, so I got the last problem straightened out and now I have another. It seems I am so close yet so far away. Here is my code;

Code:

#!/usr/dt/bin/dtksh
# Alertme.p1 program, version 0.5
# Author - Clint Sharp
mkdir ~/Msgs
echo "\nEnter your reminder message.
When finished, enter a period (.) at
the beginning of a line and press <ENTER>.
(Or press Ctrl-C to exit the script)\n"
while :
do
        read MESSAGE
        if [ "$MESSAGE" = "." ]
        then
                break
        else
                echo $MESSAGE >> ~/Msgs/message.$$
        fi
done
echo "\nEnter the time and day you want to
receive the message, for example:
0815am Jun 14
8:15am Jun 14
now + 1 day
5 pm Friday
Then press <ENTER>\n"
read TIME 
echo "\nAt $TIME mail or write $LOGNAME ~/Msgs/message.$$\n"
at -k $TIME << !!
who | cut -c1-20 | grep $LOGNAME | cut -c12-20 | cat > ~/tmp
while read inputline
do
        write $LOGNAME $inputline < ~/Msgs/message.$$ #|| mail $inputline < ~/Msgs/message.$$
done < ~/tmp
rm -r ~/Msgs
rm -r ~/tmp
exit 0

What is happening is I will have two terminal sessions opened to test this script and it is sending two messages to the same terminal. The one that originally initiated the script. I also get a mail message that says,

Code:

Your "at" job on admiral
"/var/spool/cron/atjobs/1317758851.a"
produced the following output:
I cannot determine your terminal name. No reply possible.
cs368 is logged on more than one place.
You are connected to "pts/26".
Other locations are:
pts/98Warning: You have your terminal set to "mesg -n". No reply possible.
I cannot determine your terminal name. No reply possible.
cs368 is logged on more than one place.
You are connected to "pts/26".
Other locations are:
pts/98Warning: You have your terminal set to "mesg -n". No reply possible.

On the terminal pts/98 I did change message to "yes" using the -y switch. I do not think this is the problem though. Can anyone help?

LEARN ABOUT LINUX

bsd-write

WRITE(1)						    BSD General Commands Manual 						  WRITE(1)

NAME

     write -- send a message to another user

SYNOPSIS

     write user [tty]

DESCRIPTION

     The write utility allows you to communicate with other users, by copying lines from your terminal to theirs.

     When you run the write command, the user you are writing to gets a message of the form:

	   Message from yourname@yourhost on yourtty at hh:mm ...

     Any further lines you enter will be copied to the specified user's terminal.  If the other user wants to reply, they must run write as well.

     When you are done, type an end-of-file or interrupt character.  The other user will see the message 'EOF' indicating that the conversation is
     over.

     You can prevent people (other than the super-user) from writing to you with the mesg(1) command.

     If the user you want to write to is logged in on more than one terminal, you can specify which terminal to write to by specifying the termi-
     nal name as the second operand to the write command.  Alternatively, you can let write select one of the terminals - it will pick the one
     with the shortest idle time.  This is so that if the user is logged in at work and also dialed up from home, the message will go to the right
     place.

     The traditional protocol for writing to someone is that the string '-o', either at the end of a line or on a line by itself, means that it is
     the other person's turn to talk.  The string 'oo' means that the person believes the conversation to be over.

SEE ALSO

     mesg(1), talk(1), wall(1), who(1)

HISTORY

     A write command appeared in Version 1 AT&T UNIX.

BUGS

     The sender's LC_CTYPE setting is used to determine which characters are safe to write to a terminal, not the receiver's (which write has no
     way of knowing).

     The write utility does not recognize multibyte characters.
