Frequently asked questions
Does it keep the original order?
The first occurrence of each line is kept, in its original position.
Is the comparison case-sensitive?
Check the option on the tool. If it is case-sensitive, Apple and apple count as different lines.
What about extra spaces?
Lines that differ only by trailing spaces may be treated as different, so trim them first if needed.
