Hi. I want to take two files that are supposed to be identical, then ook for any difference in the two. Text1.txt Text2.txt aaaaaa aaaaab For example, the above text files comparison would return that 'b' was found disimilar during the comparison. I have tried to upload new gems such as Diff:LCS however this did not work. I am not sure what I am doing wrong. Can you please point me in the right directions? Thanks.
