coreutils: Version sort overview

 
 30.1 Version sort overview
 ==========================
 
 “Version sort” puts items such as file names and lines of text in an
 order that feels natural to people, when the text contains a mixture of
 letters and digits.
 
    Lexicographic 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:
 
      Lexicographic 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’, and ‘sort --version-sort’ commands.
