crontab command not run

rated 0 times [ 2] [ 0] / answers: 1 / hits: 4992 / 3 Years ago, mon, june 28, 2021, 2:32:06

I'm trying to get execute a cron job everyday at noon but i can't get it to run. To test it i even tried something like a simple create command but it never runs, it seems as if the file isn't even used. I also can't see anything going wrong in the log.

0 12 * * * mkdir /path/to/folder

So is there something wrong with this line or should i look elsewhere?

I created the crontab as root with crontab -e

cron does not know where to find mkdir. So if you do not include a PATH in your cron then always use absolute paths. This works:

0 12 * * * /bin/mkdir /path/to/folder

Have a look at the part starting with using cron in the link. You can put a path and other variables at the top of cron like so:

SHELL=/bin/bash

PATH=/sbin:/bin:/usr/sbin:/usr/bin

MAILTO=root

HOME=/

That way you have access to /sbin/, /bin/, /usr/sbin/ and /usr/bin/.

I myself prefer to only include a script in cron and set the commands inside that script.
