Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:
        There's bitwise AND and bitwise OR, and logical AND and logical OR, but
        for XOR there's only the bitwise version.  Would be nice if the logical
        XOR would also be present (^^).

Fix:
        If you like the idea I can send a patch.
