This article will explain in detail the example analysis of CentOS file and directory permissions. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The environment creates two users

User1 and user2

[root@localhost ~] # useradd user1

[root@localhost ~] # useradd user2

Create two folders

[root@localhost] # mkdir-p / user1 / user2

Open another terminal and switch to su-user1

[root@localhost ~] # su-user1

Create a user2 file under user2

[root@localhost /] # touch / user2/user2

[root@localhost /] # ls-l / user2/user2

-rw-r--r--. 1 root root 0 March 20 01:37 / user2/user2

View permissions

Deleting and moving a file is related to the parent directory, even if the permission is 777, it can not be deleted as long as the parent directory has permission, even if the file itself is 000.

Even if you give him 777 permissions,

[root@localhost /] # ls-l / user2/user2

-rwxr--rwx. 1 root root 0 March 20 01:37 / user2/user2

[user1@localhost user2] $rm-rf user2

Rm: unable to delete "user2": insufficient permissions

[root@localhost /] # ls-ld / user2

Drwxr--rwx. 2 root root 4096 March 20 01:37 / user2

You can move and delete as long as the user2 directory has permission.

User1 executes delete command

[user1@localhost user2] $rm-rf user2

That's it.
