Q: What counts as a line?

A line is any text separated by a newline character (\n on Unix/macOS, \r\n on Windows). Blank lines are treated as empty lines and sorted or deduplicated accordingly. The sorter normalises line endings automatically.

Question 1

What is the difference between sort and deduplicate?

Accepted Answer

Sort reorders all lines alphabetically (or reverse alphabetically) but keeps duplicates. Deduplicate removes repeated lines while preserving the order of first occurrence. You can combine both — sort first, then deduplicate — to get a sorted unique list.

Question 2

Is the sort case-sensitive?

Accepted Answer

By default, sorting is case-insensitive so that 'apple', 'Apple', and 'APPLE' sort together. Enable case-sensitive mode if you need uppercase letters to sort before lowercase (ASCII order: A before a).

Question 4

Can I sort numeric values correctly?

Accepted Answer

Alphabetical sort treats numbers as strings: '10' would sort before '2' (because '1' < '2' as text). Enable numeric sort mode to sort numbers by their actual value so that 2 < 10 < 100.
