I have got two files of same numer of lines in each.
1,2,1,1 1,2,2,1 1,2,4,2 1,2,1,2
1,2,1,2 1,2,2,1 1,2,4,1 1,2,1,1
Now I want to compare them line by line, first line with first line, second with second and so on and print those lines in the first file (1.txt) which are not matching with the corresponding lines in the secon file (2.txt).
In this scenario the output will be:
1,2,1,1 1,2,4,2 1,2,1,2
