Code:
xterm -T Top -bg black -fg white -g 80x53 -e sudo top
That way top opens as root so I can kill an offending app if I want to. Just hightlight the proc no and k button.
For ethernet interface I have
Code:
xterm -bg black -fg white -g 20x3 -e sudo ifconfig dc0 down
I can bring the interface down fast, zone alarm like.
