Create Empty text file after successful run of Scribe Job


I have a requirement to create a dummy empty text file (in a folder) which will be used as a trigger point for other ETL batch to kick-off. I tried writing post command batch file on Integration Process in Scribe Console. This post batch always executes irrespective the Scribe Job runs successful or failure. I need to not run (not to kick-off ETL batch process) if there is failure in Scribe Job integration process. How can I achieve this?
