# List AWS S3 keys

This lists the most recent object keys (filenames) out of the bucket specified in the aws-s3-configuration.xml file (see example-customer for example format.).

“Most recent” means the keys of the objects with the most recent last modified timestamp.

The command looks like:

```
<aws-s3-keys limit="100">
    <folder>foo/bar</folder> <!-- optional -->
    <match-tag name="foo">bar</match-tag>
    <match-tag name="abc">def</match-tag>
</aws-s3-keys>
```

and the results look like:

```
<aws-s3-keys>
    <object key="folder/xyz.xml"/>
    ...
</aws-s3-keys>
```
