When running a Scheduled Batch from a command file - What can I query to find out the batch has comp

Hi,

I'm running several reports batch scheduler from a command file and calling an XML file which uses the bursting option to generates PDF files onto a specific directory.  It's working great, however, I manually have to kick the next set of XML since I do not have a way to figure out when the prior batch scheduler is complete.  I could put a sleep timer between each calls, but I'd prefer not to do so.  Normally the batch sends an email when it has executed (successfully or not).

Is there a way to find out from the command line if the batch has completed, so that the next batch can automatically run?
