Good to know
The first occurrence of each line is kept in its original position. Spaces are significant. Repeated blank lines are also deduplicated. Turn off case-sensitive comparison to treat Apple and apple as the same value.
Example: apple → pear → apple becomes apple → pear. One duplicate removed.
