I have written a cron job as follow:
45 08/3 * * * bin/run.sh job
it is getting started at 8:45 but Once it finished. Its not starting again .
To run every 3 hours, starting at 3:45
45 */3 * * * bin/run.sh job
If you're trying to skip the hours between midnight and 8:45,
45 8,11,14,17,20,23 * * * bin/run.sh job
45 8/3 * * * /bin/run.sh
. make sure path to your script.45 08/3 * * * /bin/run.sh
