There are several ways to do this, but probably the simplest is to put the following code snippet into your script1 (modify as appropriate for your environment, of course): PIDFILE=/var/state/app/test.pid # Or wherever, of course RETRY_INTERVAL=10; MAX_RETRIES=10; RETRY_COUNT=0; while [ $RETRY_COUNT -le $MAX_RETRIES ] do if [ ! -f $PIDFILE ] then let RETRY_COUNT=$RETRY_COUNT+1; sleep $RETRY_INTERVAL; else break; fi; done; There are more elegant approaches, of course--using a named pipe would be the simplest of those--but this will work.
