Run cronjob for every 10 minutes
Hi Friends,

I have a requirement to run the cronjob for every 10 minutes from 2:00 AM to 6:00 AM. Does the below code works? If not, please advise.

* * * * * command to be executed
┬ ┬ ┬ ┬ ┬
│ │ │ │ │
│ │ │ │ │
│ │ │ │ └---------------------------------- day of week (0 - 6) (0 is Sunday, or use names)
│ │ │ └------------------------------------ month (1 - 12)
│ │ └-------------------------------------- day of month (1 - 31)
│ └-----------------------------------------hour (0 - 23)
└-------------------------------------------min (0 - 59)

10,20,30,40,50 2-6 * * *

OR

*/10 2-6 * * *

The first one is the standard way so should work on any cron implementation. The second one uses a non portable extension so is non portable. You'll need to check with your cron manual page.

Both seems to work, but
10,20,30,40,50 2-6 * * * does not run on the hour (2:00, 3:00 etc), adding 00 does not work 00,10,20,30,40,50 2-6 * * *

*/10 2-6 * * *
gives

Thanks guys.

It looks like I have bumped into another problem. Smilie
I just did a basic cron stuff(below) and the job didn't run. Do I need any permissions to run the cronjobs?? Because I am not legible to access the path /var/spool/cron/ -- says, permission denied SmilieSmilieSmilie

30 01 * * * (And the path of the script)

Reasons for the execution failure????

Note: - Job runs successfully via manual process.

It would help if you tell what OS you are running.

Did you try 0,10,20,30,40,50 2-6 * * * ?

It's not clear in your request: Do you want to run up to 6:00h only or to 6:50h
