Accented characters sort where your language expects them, not at the end.
Frequently asked questions
What is natural sort?
It treats digit sequences as numbers, so file2 comes before file10. Plain alphabetical sorting would put file10 first because 1 is smaller than 2.
How does numeric mode handle text?
The first number found in each line is used for ordering. Lines without a number are treated as zero and stay near the start of an ascending sort.
Is the sort stable?
Yes. Lines that compare equal keep their original relative order, which matters when sorting by length or by a number shared by several lines.
Can I sort a CSV by one column?
Not directly. This tool sorts whole lines; for column-based sorting use a spreadsheet or a command-line tool such as sort -t, -k2.
