Cron job every 6 hours

[Boris88]

I saw few conversations in this forum about crontab and that dietpi uses predefined times for cron jobs
how to add cron job to execute every 6 hours?
I wanna use the script that i made in /home/dietpi/nzb_subliminal_master/translate.ch

is this the right formating for every 6 hours: 0 */6 * * *

I created one using Webmin - make it very easy - this is what it created, but you can be as flexible as you like.

* 0,6,12,18 * * * /home/john/scripts/test.sh

So it runs at midnight, 6 AM, 12 noon, 6 PM.

Is it possible to add cron without installing new program..
I see that webmin is a program in quick google search
i saw that people type crontab -e in terminal
or can i edit one of the profiles that exist in dietpi for example if i dont need cron job monthly
please be specific with code, i'm linux noob.. Thanks

Yes and no ...

• install via dietpi-software - No
• install via apt-get install - Yes
  but you have to read: DebianReleases > Backports and https://packages.debian.org/source/stretch/minidlna

And ...

you can do what ever you want to do, but if something afterwards don't work, you be in self authority ... good luke!
