Learning the terminal. Found this nice android app: "Linux Command Library"

It lists a number of man pages and examples.

I found this one:

block known dirty hosts from accessing your machine

wget -qO - http://infiltrated.net/blacklisted|awk '!/#|[a-z]/&&/./{print "iptables -A INPUT -s "$1" -j DROP"}'

I figured that domain was a list of spam sites and such.

Googled it. Found nothing mentioning it. Went to the domain and it was blocked by my ad blocker.

Anyone know of it?
