How duplicates are counted
Two lines are treated as identical if they match completely. Spaces at the edges don't matter: "item " and "item" are the same line. Without "Match case", "Item" and "item" in lowercase are also the same. Line order is kept, and one line stays from each group of duplicates.
First or last occurrence
Usually the first occurrence is kept: the line stays where it first appeared. "Last" is useful for logs and exports where the newest entries are at the bottom.
Duplicates only
"Show duplicates only" outputs the lines that appear more than once - each of them once. With "With duplicate count", you also see how many times each line appears. This is handy for finding duplicate orders, emails in a mailing list or keywords.
