FAQ
Does order matter?
By default the first occurrence of each line is kept in its original position; enable sorting to alphabetize the result instead.
Does it trim extra whitespace before comparing?
Yes, leading/trailing whitespace is trimmed before comparing lines so near-identical entries are correctly matched as duplicates.
