sending message to terminal

hi all
i have script
#!/bin/bash
cd /usr3/prod
grep ERROR /usr3/prod/ind.log > /usr3/prod/ind_err.log
if test -s /usr3/prod/ind_err.log
then
echo "error during process"
else
echo "process succeed"
fi
i want that this message(echo) will be display one time at the top of the screen to all the pc stand (sessions)
and not just to the current terminal(session) that runs it ,without preventing from the other process that runs in the sessions to run.
how shell i do this ?
please help
thanks

No, you can run this safely, it won't hold/interrupt other processes !!!!!!
