[gentoo-user] Non-case sensitive alphabetical sorting

When ordering items by name, a separate and distinct sequence is scene for
A-Z before the sequence for a-z. This is the expected behavior. What might i
need to look up to intermix [Aa]-[Zz]?

That depends on what you are using to do the sort. The sort command uses
the -f option for case-insensitive sorting. Bash has an option to handle
this when presenting files that match a pattern, like *, see the man page.

A more detailed question will elicit a more detailed answer.

Maybe should state in what application you are trying to sort...

Schwartzian Transform is the perlish version of a
technique from LISP: create a compound structure
with the output as payload:

     my @sorted
     = map
     {
         $_->[-1]
     }
     sort
     {
         $a->[0] cmp $b->[0]
     }
     map
     {
         my $sortval = uc $_;

         [ $sortval, $_ ]
     }
     @unsorted_text;

You can use the basic technique to sort anything
(multi-level sorts, numeric, whatever). Same basic
process works in other languages that support anon
arrays or structs.

I'm sorry, I wasnt clear in my original post.

When using gnome in ubuntu, clicking the sort by name in nautilus sorts using
[Aa]-[Zz]

When using gnome in gentoo, clicking the sort by name in nautilus yields
A-Z-a-z.

The same thing happens for coreutils ls, and so on.

Is there any file or configuration I have to check to use case
insensitive sorting
in gnome?

Not for me.

Check your LC_ALL environment variable.

great! what's the correct place to set this globally so that both
terminal and gnome will see it?

/etc/env.d/02locale

You need to do 'env-update' as root after any changes there followed by 
'source /etc/profile' (or logging out and in again).
