# Sending Reports to an AWS S3 Bucket To save reports directly in an S3 bucket, use: `-B`/`--output-bucket`. ```sh prowler aws -B my-bucket ``` ### Custom Folder and Filename For a custom folder and/or filename, specify: `-o`/`--output-directory` and/or `-F`/`--output-filename`. ```sh prowler aws \ -B my-bucket \ --output-directory test-folder \ --output-filename output-filename ``` ### Custom Output Formats By default, Prowler sends HTML, JSON, and CSV output formats. To specify a single output format, use the `-M`/`--output-modes` flag. ```sh prowler aws -M csv -B my-bucket ``` ???+ note If you prefer using the initial credentials instead of the assumed role credentials for uploading reports, use `-D`/`--output-bucket-no-assume` instead of `-B`/`--output-bucket`. ???+ warning Ensure the credentials used have write permissions for the `s3:PutObject` where reports will be uploaded.
