Frequently asked questions
Are lines that differ only in capital letters treated as duplicates?
No. Lines are compared exactly as written, so Apple and apple are kept as two different lines. Convert the text to one case first if you want them merged.
Which copy of a repeated line is kept?
The first occurrence stays where it was and later copies are removed, so the original order of your list is preserved.
