Suppose a directory `dir1` is created by `sudo` on Desktop.

```
sudo mkdir dir1

```

Then I applied `chown` and `chmod` as following:

```
sudo chown root:root dir1
sudo chmod go-rwx dir1

```

Now `dir1` is only accessible with owner `root`.

```
$ ls -ld dir1
drwx------ 2 root root 4096 Jul 29 19:21 dir1

```

If user (`$USER` = `pandya`) try to delete `dir1` with **GUI nautilus (without `sudo`)**, then he can't **which is ok**.

![enter image description here](https://i.stack.imgur.com/SQ6SQ.png)

**But if tried to remove with terminal then he can which is not ok:-**

* **`rm -r` (without `sudo`):**

```
 $ rm -r dir1
 rm: descend into write-protected directory ‘dir1’? Y
 rm: remove write-protected directory ‘dir1’? Y
 $

```
* **And more easily with `rmdir` ! (without sudo):**

```
$ rmdir dir1
$ 

```

**Thus, How to prevent `dir1` to be delete with user than not `sudo`?**

[optional]  

My ultimate aim is: Only owner can delete directory, group and other only can read/execute.
