Cron Job Not Running?

rated 0 times [ 25] [ 0] / answers: 1 / hits: 98065 / 2 Years ago, wed, february 2, 2022, 10:41:05

I have a crontab file that looks like this:

* * * * * /home/abliskovs/update/update.sh

However when I check the syslog for evidence that the job has run, there is nothing that might indicate that it ever ran. How can I check if it's running?

crontab -l outputs the following:

* * * * * /home/abliskovs/update/update.sh

Add a >>/tmp/testlog.log to the end of your crontab entry (to redirect
output to a file you can investigate or check if it's running,
additionally a 2>&1 would include output from the error console)

Example

0 * * * * /home/abliskovs/update/update.sh 2>&1 /tmp/testlog.log

Also Make Sure the followings :

Add cronjobs in a right manner. if you've used crontab -e within your own account, scripts are run with your user (and thus the
crontab entry has one field less -- the user to run it, as that is
known). If you simply copied your above snipped to /etc/cron.d, it
would fail as you didn't specify a user (or rather as it finds no
user named "bash").

Make sure that the script file is executable, otherwise it will not
execute it.

Reload the cron jobs sudo service reload, or restart cron service sudo /etc/init.d/cron restart

How to make a file executable?

Several ways to make your file executable

chmod +x /home/abliskovs/update/update.sh 



chmod -R 0755 /home/abliskovs/update/update.sh



chmod a+x /home/abliskovs/update/update.sh
