Hello,

I would like to run a script from crontab every 2 hours, another every 2 hours and 5 minutes, and finally one more every 2 hours and 10 minutes, and I can’t remember how to do it.

Thanks in advance.

Hello,

every 2 hours means at an interval of 2 hours
if I start at 0 it gives 0 2 4 ....
*/2 * * * * script.sh
on the other hand if you want every day at 2:05
5 2 * * * script.sh

Hi,

Are you sure */2 * * * * script.sh doesn't execute it every 2 minutes???

Because when I do */1 * * * * myScript it executes it every minute.

* */1 * * * = every minute ;-)
you need 0 */1 * * * to have that every hour and it comes back to 0 * * * *
every 2 hours => 1 */2 * * * it executes every 2 hours after 1 minute
