What controls the order that the ls command uses for sorting names?
On a fresh Squeeze installation, ls seems to ignore leading "."
characters (it no longer lists all "hidden" files adjacent to each
other) and to ignore capitalization differences.
It used to sort in standard/traditional Unix order (not ignoring any
characters, and ordering by order of characters in ASCII/etc. (as
opposed to by case-insensitive alphabetical order)).
What controls ls's sorting order?
I haven't set any locale environment variable specifically for the
collation order, but I don't know what base LANG=en_US.UTF-8 setting
does. Does "en_US" imply that new sorting order?
How do I tell ls to work the way I've seen it work for decades?
