Sorting \"Dot\" Files

As I got Cent OS 7.4 running, a bit strange thing happened. When I ran usual ll (alias to ls -lA), I got a slightly unexpected result:

ll
 drwxrwx--- 4 apache apache  4096 Dec 24 06:50 download
 -rw-rw---- 1 apache apache  5430 Dec 23 08:06 favicon.ico
 -rw-rw---- 1 apache apache 12300 Dec 26 02:25 .htaccess
 -rw-rw---- 1 apache apache   460 Dec 23 08:06 index.php
 -rw-rw---- 1 apache apache   117 Dec 23 20:39 robots.txt
 drwxrwx--- 2 apache apache  4096 Dec 26 01:44 .well-known
 drwxrwx--- 5 apache apache  4096 Dec 23 17:32 wordpress

Can you spot the issue?

Yep, Cent OS got a bit (too) smart so sorting ignores the starting dot and gets those files too in the alphabetic order. Those used to dot files on the top - though luck.

Well, it’s possible to “correct” this behavior using the slightly different alias in .bashrc:

alias ll='LC_COLLATE=C ls -lA'

This gives a (properly) sorted output:

ll
 -rw-rw---- 1 apache apache 12300 Dec 26 02:25 .htaccess
 drwxrwx--- 2 apache apache  4096 Dec 26 01:44 .well-known
 drwxrwx--- 4 apache apache  4096 Dec 24 06:50 download
 -rw-rw---- 1 apache apache  5430 Dec 23 08:06 favicon.ico
 -rw-rw---- 1 apache apache   460 Dec 23 08:06 index.php
 -rw-rw---- 1 apache apache   117 Dec 23 20:39 robots.txt
 drwxrwx--- 5 apache apache  4096 Dec 23 17:32 wordpress
