Linux vs. Unix file wildcards
The result depends on different shell options, particularly: nocasematch nocaseglobAnd also LC_COLLATE variable (used in sort, [-], etc.)
$ shopt extglob nocasematch nocaseglobextglob offnocasematch offnocaseglob off$ printf "%s\n" a A b B c C | sortaAbBcCSo [A-C] range contains b and c, but not a, also [a-c] should contain A but not C.
$ printf "%s\n" a A b B c C | LC_COLLATE=C sortABCabcgives a different result.
$ LC_COLLATE=C ls [A-C]*Should return expected result, this syntax sets the variable only for the new process execution (ls), but not in current shell process.
EDIT: thanks to comment, previous command is wrong because the expansion is processed before the LC_COLLATE be set, the simplest is to split into two commands.
$ export LC_COLLATE=C$ ls [A-C]*
