What is 'natural' sort vs lexicographic?

Lexicographic sorts character by character: 'file10' < 'file2' (because '1' < '2'). Natural sort treats digit sequences as numbers: 'file2' < 'file10'. Use natural sort for filenames and version-like strings.

How are duplicates identified?

By exact line equality after optional trimming. Lines that differ only in trailing whitespace are considered different unless you enable trim. For case-insensitive dedup, enable that option — but the first occurrence's case is preserved.

Sorting and deduplicating a line list is a common data prep step — cleaning log entries, deduplicating URLs, preparing import lists. Sorting makes diffs readable; deduplication removes redundant entries.

Use the chain to deduplicate then sort in one pass, with options for trimming whitespace and ignoring blank lines.
