**To start an asynchronous PII detection job**

The following ``start-pii-entities-detection-job`` example starts an asynchronous personal identifiable information (PII) entities detection job for all files located at the address specified by
the ``--input-data-config`` tag. The S3 bucket in this example contains ``Sampletext1.txt``, ``Sampletext2.txt``, and ``Sampletext3.txt``. 
When the job is complete, the folder, ``output``, is placed in the location specified by the ``--output-data-config`` tag. The folder contains 
``SampleText1.txt.out``, ``SampleText2.txt.out``, and ``SampleText3.txt.out`` which list the named entities within each text file. The Json output is printed on one line per file, but is formatted here for readability. ::
