read LOGNAMES

for NAME in $LOGNAMES
     do
     echo $MESSAGE | write $NAME$
     DONE
EOF

NAME needs to be a variable in the script and not expanded when the script is written to at. So, if you escape it /$NAME that will put it literally in the script ($NAME) and not what name contains (which is nothing). Drop the last dollar sign.

The only other problem I see is that DONE should be lower case. That might just be a cut/paste issue; hard to say from this end.

With those changes it should send you mail with the list of names (I'd use echo to avoid errors if the list is empty).

Have a go with those changes -- you're a lot closer than you think!

Thanks and I got it, but I believe the $NAME should be \$NAME. That is the way it worked for me. I appreciate your help!

Clue:
How are you going to get the $tty ?
Portion corrected
Code:
who | grep $LOGNAME | sed 's,.*\(pts/[0-9]*\).*, \1 ,' |
while read tty
do
  echo $MESSAGE | /dev/$tty
done

#
execution:
#
an12:/home/vbe $ who | grep $LOGNAME | sed 's,.*\(pts/[0-9]*\).*, \1 ,'|
> while read tty
> do
>   echo $MESSAGE | /dev/$tty
> done
/usr/bin/ksh[4]: /dev/pts/14: 0403-006 Execute permission denied.
/usr/bin/ksh[4]: /dev/pts/24: 0403-006 Execute permission denied.
/usr/bin/ksh[4]: /dev/pts/27: 0403-006 Execute permission denied.

You carry on now...

I believe I know where you are going. I used the above for loop instead but I think you are pointing out the fact that some users might have there tty's turned off for receiving messages. Is that correct? My time was limited on getting the assignment done. I had thought of that though.

Ack!! I've been typing too many HTML tags by hand!

Glad it worked.
