Centos Delete folder permission denied

The folder extracted with the tar command has a lock and cannot be deleted;

For example:

Use rm-rf to delete the output as follows:

Key Information found after sudo execution: xxx is not in the sudoers file.

Solution:

First, you need to switch to the root identity
$ Su-
(Note that there is-, which is different from su. When the "su" command is used, the system only switches to root, but does not pass the root environment variable, or the current user's environment variable. Use the "su-" command to bring the environment variable together, just like root login)
Then
$ Other do // remember, there is no space between vi and sudo.

1. ": $" move the cursor to the last line
2. Press a to enter the append mode.
3. Enter your username and subsequent information
Your_user_name ALL = (ALL) ALL
4. Press Esc
5. Enter ": wq" (Press enter to save the file and exit)

In this way, you can add yourself to the sudo group and use the sudo command.
