查找无主文件和组只是完成了一半任务：还需要确定谁应该拥有它们及其应具有何种组权限。
Finding unowned files and groups is only half the battle: you also have to decide who should own them and what group permissions they should have.
较好的做法是编写一个脚本来查找所有文件——还可以使用脚本帮您修复权限。
It's a good thing you can write a script to find all the files for you — and you can have it fix the permissions, as well.
