I'm not sure this will help. Here's the situation:
script1 - checks for the existence of test.pid
script2 - the job that actually will create the pid
I'm answering this, instead of the original request, since you actually
described what you're trying to do more clearly here.
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.
