Frequently Asked Questions
What does 'preserve order' mean?
When enabled, the original order of lines is kept and only the first occurrence of each duplicate is retained. When disabled, the output is sorted.
What does 'trim whitespace' do?
When enabled, leading and trailing spaces are removed before comparing lines. Two lines that differ only in whitespace will be treated as duplicates.
