We've specified the following parameters in the call to the `s3 ls` command:

| Name           | Description                                                            |
| -------------- | ---------------------------------------------------------------------- |
| recursive      | applies the `s3 ls` command to all files under the specified directory |
| human-readable | displays the file sizes in human-readable format                       |
| summarize      | displays the number of objects and total size of the files             |

<Alert>
  List requests are associated with a cost. At the time of writing the cost of{' '}
  <code>1,000</code> list requests is <code>$0.005</code> in the{' '}
  <code>us-east-1</code> region.
</Alert>

## Count Objects in a Folder of an S3 Bucket with AWS CLI

**To count the number of objects in a specific folder in your S3 bucket, use the
`s3 ls` command and specify the path of the directory, e.g.
`s3://my-bucket/images/`.**

```bash:shell
aws s3 ls s3://YOUR_BUCKET/folder/ --recursive --human-readable  --summarize
```

![count bucket objects in folder](/images/blog/aws-cli-count-number-of-objects-in-s3-bucket/count-bucket-objects-in-folder.webp)

The output shows that the `personal-website-bac/` directory consists of 4
objects.
