Your question is vague and may receive several distinct answers.

I've always found this reference to be extremely valuable when the question boils down to comparing strings, in the general case. Algorithms explanations and comparison runs, example code in various languages could help you select a smart solution for your problem.

Else run diff is also a good way.
