Ah, basic shell programming question :)
Something like:
---------------------------------
#! /bin/sh
tail -f /var/log/messages | (
while read line
do
case "$line" in
*emergency*)
echo "EMERGENCY: $line" > /dev/console
;;
*"ippp0: dialing"*)
echo "DIALING: $line" > /dev/console
;;
esac
done
)
---------------------------------
Well, you get the idea ..
Mike.
