Maybe this will do what you want.

a = ["ali", "bel", "del","en"]
b = ["ali","bas","del","sx","en","sz","zen"]

p a&b


But, to kind of answer your question,


a = ["ali", "bel", "del","en"]
b = ["ali","bas","del","sx","en","sz","zen"]


for xa in a
 $ye= xa
end

puts $ye #Look here.

p $ye
b.each do |bx|
 $bu = bx

puts $ye #And look here.

   if $ye == $bu
     puts "#{$ye} and #{$bu}"
   end
end
