UNIX for Dummies Questions & Answers

hi,

I need to send a message to multiple users to all there logged on terminals

i tried write but its send to only one user and only one terminal

i cant use wall command because all the people in group should not receive the message

Type who to find out which terminals you want to write to, then, as root...

echo "Some message here" | tee /dev/pts/1 /dev/pts/2 /dev/pts/3

Not elegant, but it'll do the job

Cheers

I assume that you only want a particular group to receive the message. Do:

[B]man wall

Read about the -g option which allows you to broadcast to a specified group.

Hope this helps.

Thanks gilberteu for the wall -g command but

I do not want to send to every one in group
any how

who | grep -E "user1|user2|user3" | tr -s " " ""| cut -f 2 -d " " > temp

gave all the terminal the required users logged on to and then

cat Temp | while ln=`line`
do
echo "Message to Send" | tee /dev/$ln
done

sends the message to all required terminal

tee /dev/pts/15 send message to person logged on pts/15

Thanks zazzybob
the tee was quite helpful
