#### [ CLI ]
**AWS CLI**
**Untuk mengambil konfigurasi retensi objek untuk objek**
`get-object-retention`Contoh berikut mengambil konfigurasi retensi objek untuk objek tertentu.
```
aws s3api get-object-retention \
--bucket amzn-s3-demo-bucket-with-object-lock \
--key doc1.rtf
```
Output:
```
{
"Retention": {
"Mode": "GOVERNANCE",
"RetainUntilDate": "2025-01-01T00:00:00.000Z"
}
}
