Hi,

Thanks for responding, here is a simplified case. Say I have this as input
Code:
1-num1
2-num2
3-num2
4-num3
5-num3
2-num2

Now what I want to do is not just find repetitions and remove them, but to find repetitions that are only in the next line and remove the first occurrence of that value. Repetitions are checked on $2 with FS as "-". So the output should be

Code:
1-num1
3-num2
4-num3
5-num3
2-num2
