Ruby implementation modifies the Hosts_ruby topic under Ubuntu

Under Windows, we all know where the hosts file is, but in the Ubuntu system, there are other systems, such as the Android phone, and maybe there aren't as many small software that you can easily modify, so let's write it ourselves.

#!/usr/bin/ruby
#coding =utf-8
require ' Open-uri '

url= ' http://raw.github usercontent.com/vokins/ Simpleu/master/hosts "

begin
 Open" ("/etc/hosts", "w") do |x|
  X.write open (URL). Read
 End
rescue errno::eacces
 puts "Need root?"
 exec "sudo ruby" + $ + $ + argv.join ("") End
puts "Write hosts success!"
