# Removing Metadata from DataHub There are a two ways to delete data from DataHub. ## Delete By Urn To delete all the data related to a single entity, run ```aidl datahub delete --urn "" ``` _Note: make sure you surround your urn with quotes! If you do not include the quotes, your terminal may misinterpret the command._ ## Rollback Ingestion Batch Run Whenever you run `datahub ingest -c ...`, all the metadata ingested with that run will have the same run id. To view the ids of the most recent set of ingestion batches, execute ```aidl datahub ingest list-runs ``` That will print out a table of all the runs. Once you have an idea of which run you want to roll back, run ```aidl datahub ingest show --run-id ``` to see more info of the run. Finally, run ```aidl datahub ingest rollback --run-id ``` To rollback all aspects added with this run and all entities created by this run.
