您似乎已在交互式外壳程序中启用了shopt -s extglob，从而打开了扩展的globing.这不是默认行为，需要在脚本中显式启用.有关详细信息，请参见bash黑客Wiki中的扩展模式匹配.

You seem to have shopt -s extglob enabled in your interactive shell, which turns on extended globbing. This is not the default behavior, and needs to be explicitly enabled in your script. See extended pattern matching in the bash hackers wiki for details.
