version sort ordering (and similarly, natural sort ordering) is a method to sort items such as file names and lines of text in an order that feels more natural to people, when the text contains a mixture of letters and digits.
Standard sorting usually does not produce the order that one expects because comparisons are made on a character-by-character basis.
Compare the sorting of the following items:
Alphabetical sort: Version Sort: a1 a1 a120 a2 a13 a13 a2 a120
version sort functionality in GNU coreutils is available in the ‘ls -v’, ‘ls --sort=version’, ‘sort -V’, ‘sort --version-sort’ commands.
