egrep trick

Here’s a neat trick. I wanted to highlight some output I was watching so it would stand out, in this case a specific IP address on a load balancer. The trick is to use egrep to colorize and match your pattern or the end of line.


while :
	do
	clear
	ipvsadm -L -n | grep 2099 | egrep --color "10.10.0.8|$"
	sleep 10
done
