Hello everyone!

I am struggling to detect in a script whether the current user is root or
not. Etc.getlogin seems to return my unpriveleged username even after
I have done an 'su' or run the script with 'sudo' to become root.

All I really need is:

if Etc.getuid != 0
puts "You are not root"
exit
end

--
ruby -e "puts 'Just another fickle programmer'"
