bash LC_COLLATE or LC_ALL set “C” not sort in dictionary order.

[Edward Martinez]

     Hi,

     Been trying to get BASH to sort set characters in  dictionary order.
    I typed "locale" and it shows LC_COLLATE and LC_ALL are set to "C" 
thought that was enough to work,
    however when i type metacharacters:  set character; any character, 
something like this:

        ls  [a-cx-y]*

     bash does not sort in dictionary order; file   "Binarc" does not  
list.

     Am I leaving something out?
