What sort order does Linux use?

My Bash script runs files in a folder in alphabetical order. But it turns out that this is not the order that I have in the Mac OS folder. So now I am wondering what sorting order Linux uses, and can it be changed? Can I change it only for my bash script? Say I want to run a video player in a Bash script by running all the videos in a folder in alphabetical order, can I indicate in the script what alphanumeric order it should be?

The sort order for many teams (including bashglob, ls, sort) is based on your current locale settings.

You can force the mapping by setting the environment variable LC_COLLATE. Setting it to C will perform a comparison by byte values.

On my system (en_US.utf8):

sh$ touch eleve
sh$ touch élève
sh$ touch Eleve 
sh$ touch Élève
sh$ touch äkta
sh$ touch österreich

sh$ ls
äkta  eleve  Eleve  élève  Élève  österreich  pommes

sh$ LC_COLLATE=fr_FR.utf8 ls
äkta  eleve  Eleve  élève  Élève  österreich  pommes

sh$ LC_COLLATE=sv_SE.utf8 ls
eleve  Eleve  élève  Élève  pommes  äkta  österreich

sh$ LC_COLLATE=C ls
Eleve  eleve  pommes  Élève  äkta  élève  österreich
