Hi,
U can do like,
irb(main):001:0> a=File.open("a","r")
=> #<File:a>
irb(main):002:0> arr=a.readlines
=> ["1\n", "2\n", "3\n", "4\n", "45\n", "1\n", "23\n", "4\n", "56\n", "3\n",
"12\n", "45\n", "6\n", "34\n"]
read the lines from file and assign into an array.
irb(main):003:0> arr.length
=> 14
irb(main):004:0> arr.uniq
=> ["1\n", "2\n", "3\n", "4\n", "45\n", "23\n", "56\n", "12\n", "6\n",
"34\n"]
irb(main):005:0> arr.uniq.length
=> 10
Using the array only we can unique the values.
