In your script itself you can echo the REORG statement and write the output of the success/failure to an output file. If you want to kill the execution of the process, then from the output file of the script you will come to know upto which table the REORG was successfully executed.
Also, you can use the LIST HISTORY.. REORG command to see which are the tables REORGed today.
