Converting string output to array

1

I have to convert the output in the below format to array , how can this be achieved in ruby

Output:
10.1.1.1
10.1.1.2
10.1.1.3

To:
array = [“10.1.1.1”,“10.1.1.2”,“10.1.1.3”]

2 
a = "10.1.1.1
10.1.1.2
10.1.1.3"

array = a.split("\n")
p array     # => ["10.1.1.1", "10.1.1.2", "10.1.1.3"]

If the output is stored in a file output.txt:

b_array = File.readlines("output.txt").map{ |i| i.chomp }
p b_array   #  => ["10.1.1.1", "10.1.1.2", "10.1.1.3"]
