原因解释
1.As root, change the permissions of a file to 000. This file and its contents can only be accessed by root.
2.As a user, change the permissions of your own file. The file and its contents cannot be accessed by the user. But the root has full privileges on the file.
本文深入探讨了Linux系统中文件权限设置为000时的访问特性,详细讲解了root用户与普通用户对文件的不同访问权限,以及这些权限如何影响文件的可读、可写和可执行性。
