Frequently asked questions
Does it keep blank lines?
Yes. Blank lines are preserved so your structure stays intact; only repeated non-blank lines are removed.
What is adjacent-only mode?
It removes a line only when it repeats the line immediately before it, leaving non-adjacent repeats.
Which copy is kept?
The first occurrence of each line is kept; later duplicates are removed.
