Frequently Asked Questions
Does it keep the first or last occurrence?
It keeps the first occurrence of each unique line and removes subsequent duplicates in original order.
What does case-insensitive mode do?
It treats "Hello" and "hello" as the same line, keeping the first occurrence with its original casing.
Does it remove empty lines?
Empty lines are preserved by default. Use the Trim option to also remove blank lines.
