 `acr purge` supports several optional parameters. The following two are used in examples in this article:

+* `--untagged` - Specifies that all manifests that don't have associated tags (*untagged manifests*) are deleted. This parameter also deletes untagged manifests in addition to tags that are already being deleted.
 * `--dry-run` - Specifies that no data is deleted, but the output is the same as if the command is run without this flag. This parameter is useful for testing a purge command to make sure it does not inadvertently delete data you intend to preserve.
 * `--keep` - Specifies that the latest x number of to-be-deleted tags are retained.
 * `--concurrency` - Specifies a number of purge tasks to process concurrently. A default value is used if this parameter is not provided.
