How to make crontab for znc

Usually you don't need any crontab for znc as they are working as service, or in background.

Can you explain what you try to do ?

Let us familiarized the value of crontab schedule:

Code: Select all

┌───────────── minute (0 - 59)
│ ┌───────────── hour (0 - 23)
│ │ ┌───────────── day of the month (1 - 31)
│ │ │ ┌───────────── month (1 - 12)
│ │ │ │ ┌───────────── day of the week (0 - 7) (Sunday is 0 or 7)
│ │ │ │ │
* * * * *  <command to run>

here's some example of crontab for znc:

1. # Crontab entry to restart ZNC at midnight every day (which I personally use)

Code: Select all

(crontab -l 2>/dev/null; echo "0 0 * * * /usr/bin/znc -r") | crontab -

2. # adding znc in startup (after system restart/reboot)

Code: Select all

@reboot /usr/bin/znc

3. # it will rerun after 5 minutes

Code: Select all

*/5 * * * * /usr/bin/znc 

4. # At the top of every hour

Code: Select all

0 * * * *  /usr/bin/znc

note: Use

Code: Select all

* * * * * /usr/bin/znc

carefully — if your script is heavy or has side effects, it could overload the system by running every minute.

#edited as pointed out by @CrazyCat ( from znc to /usr/bin/znc - full path )

Just a small tip: don't use "znc" and prefer "/usr/bin/znc"

crontab works without user logged, so env is not loaded, especially $PATH. So crontab may not found where znc is. If you give the full path, there is no trouble.

Which reminded me of something. Long ago, I stumbled onto a website somehow. It is so useful, that I still use it !

https://crontab.guru/

See the part near the center " 5 4 * * * " that is inside a lighter colored oval? Just click on a value, and you can change it. You'll see.



I hope that this is helpful to somebody, someday.
