TIme of execution of daily anacron job

rated 0 times [ 7] [ 0] / answers: 1 / hits: 11316 / 3 Years ago, tue, may 18, 2021, 1:12:26

I have set a daily anacron job, which runs form /etc/cron.daily. From the /etc/crontab I see it should run daily at 06:25 (or at start-up/reboot).

However when the date changes (00:00) and the computer is up, I dont want anacron to wait till 06:25. If the computer is up I would like to it to run the script as soon as the date changes (00:00). Does it make sense to add a cron job to run anacron @hourly?

Thank you very much

I found how to do this and summarized it in my blogpost:

http://opensourceresearchtips.blogspot.com/2012/01/linux-anacron-tips.html

If you want to change the behaviour of anacron to execute as soon as the day changes (and not wait till 7:30 as is the default behaviour) do the following:

gksu gedit /etc/cron.d/anacron

and add the last 2 lines (the last line will restart anacron every hour):

01 0    * * *   root test -x /etc/init.d/anacron && /usr/sbin/invoke-rc.d anacron start >/dev/null

01 0    * * *   root start -q anacron || :

@hourly root start -q anacron || :
