Then we **assign those two values** of the tuple to the variables `id` and `name`.

So, if the user didn't provide an item ID, they will still receive a random suggestion.

...we do all this in a **single simple line**. 🤯 Don't you love Python? 🐍

## Recap { #recap }

```sh
$ mc tree --files ~/.minio
/home/user1/.minio
└─ certs
   ├─ CAs
   ├─ private.key
   └─ public.crt
```

You can provide a custom certs directory using `--certs-dir` command line option.

#### Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

```sh
export MINIO_ROOT_USER=minio

        // Reserved (4 bytes) - The implementation skips writing these bytes,
        // so they will have the initial pattern (0xCCCCCCCC)
        // This is expected behavior as seen in the implementation at line 131
        assertEquals((byte) 0xCC, buffer[4]);
        assertEquals((byte) 0xCC, buffer[5]);
        assertEquals((byte) 0xCC, buffer[6]);
        assertEquals((byte) 0xCC, buffer[7]);
