egrep trick

Tuesday, November 29th, 2011

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 :
	ipvsadm -L -n | grep 2099 | egrep --color "|$"
	sleep 10
