Ruby implements modification of hosts and rubyubuntu under ubuntu

In Windows, we all know where to modify the hosts file, but in ubuntu, there are other systems, such as Android phones, maybe there aren't so many small software for you to simply modify. Let's write it by ourselves.

#! /Usr/bin/ruby # coding = utf-8require 'open-url' url = "http: // raw. github usercontent.com/vokins/simpleu/master/hosts "begin open ("/etc/hosts "," w ") do | x. write open (url ). read endrescue Errno: EACCES puts "Need root? "Exec" sudo ruby "+ $0 + ARGV. join ('') endputs "Write hosts success! "
