Unix's 'ls' sort by name

My ls sorts by name by default. What are you seeing?

man ls states:

List information about the FILEs (the current directory by default). Sort entries alpha‐betically if none of -cftuvSUX nor --sort is specified.:

For something simple, you can combine ls with sort. For just a list of file names:
ls -1 | sort

To sort them in reverse order:
ls -1 | sort -r

ls from coreutils performs a locale-aware sort by default, and thus may produce surprising results in some cases (for instance, %foo will sort between bar and quux in LANG=en_US). If you want an ASCIIbetical sort, use

LANG=C ls
