Is the duplicate check case-sensitive?
Yes, "Hello" and "hello" are treated as different lines. Only lines that match exactly, including capitalization and whitespace, are removed as duplicates.
Which occurrence does it keep, the first or the last?
The first occurrence of each line is kept and later duplicates are removed. The order of the remaining lines is preserved from your original list.
