No, it's the specification of how character ranges in glob(3) and
fnmatch(3) work.  In effect, character ranges like [a-z] must be
treated as ranges of *collating elements*, not byte ranges, and in
your locale, <a> and <A> are considered to be the same collating
element, so [a-z] matches both upper- and lower-case Latin letters.
This is documented, very obliquely, in sh(1), which also tells you the

a character class. A character class matches any of the characters between the square brackets. A locale-dependent range of characters may
     be specified using a minus sign.  A named class of characters (see
wctype(3)) may be specified by surrounding the name with `[:' and `:]'. For example, `[[:alpha:]]' is a shell pattern that matches a single let-

So, to match only lower-case letters regardless of your current locale
setting, you must use the correct character class:

        $ locale
        $ ls
        D       E       F       a       b       c
        $ ls [[:lower:]]*
        a       b       c

The same applies to character class ranges in regular expressions, not
just glob(3) patterns.


  It's only work in SH, in C shell (or tcsh) not work
   and it's not work if I need to do this:

   I think this not correct.

$ ls [a-c,k-l]*
a       A       b       c       k       l
$ ls [[:lower:]a-c,k-l]*
a       c       f       i       l       o       r       u       x

If I'll use the rm command I'll erase file that not match with my selection.

Imagine if I has a script to work in batch mode and it's occur, can be a too
