Which shell also matters. The OP appears to be using ^ to negate,

I think ^ has been deprecated recently. I failed to find a reference on the web just now though.
POSIX specifies that ! is the negation character in glob ranges, largely
because ^ used to be a synonym for | in the old Bourne shell (for the
benefit of keyboards that didn't have a convenient | character).
The use of ^ as a glob negation is a bash extension. It's nice for
people who may not even realize that they're supposed to be using !
because they learned regular expressions first.
So, ^ isn't "deprecated". It's just not portable to sh.
