Find and count duplicate lines
The tool splits your text into lines and counts occurrences of each unique line. Lines that appear more than once are identified as duplicates, with their count displayed next to each line.
No, empty lines and lines containing only whitespace are filtered out during processing. Only lines with actual content are analyzed for duplication.
Duplicates are sorted by frequency count in descending order, with the most frequently occurring lines appearing first. This helps identify the most common duplicates quickly.
Unique duplicates count how many different lines are duplicated. Total occurrences count how many times all duplicated lines appear. For example, if "apple" appears 3 times and "banana" appears 2 times, there are 2 unique duplicates and 5 total occurrences.
