It's not (just) because the words or phrases don't start at the beginning of a line. If you use hashes like that, the two lines would have to match EXACTLY, byte for byte, without the slightest difference.

Also, your current program will give you a false positive if a line is duplicated in either of the two files.

You need to specify more precisely just what you mean by "match." Do you mean that a line of one file is a substring of a line in the other file? If f1.txt has a line with just the four letters "bell", should that match a line in f2.txt that has the phrase "the antebellum south"?

Once you specify what you want, we can be more help.
