How to know

[babeo]

Could someone tell me how to check for the cronjob running or not? I have many cron jobs running background, but recently just 1 or 2 of them died and usually I will get the system alarms me, but guess what this cronjob also died, which I don't know there are some cron job died too.

I can check by listing the crontab -l and check whether the job listed in the crontab list is running at the time desired or not, but I am not sure is there another fater way to check them out?

thanks.

normally cron-jobs will give you a line in the system-log with the error-code

Hi this process may help you,

I would like to know, after making changes in crontab file, are you getting any error messages like this

cron may not be running - call your system administrator

If yes, then stop and start the cron

#/etc/init.d/cron stop
#/etc/init.d/cron start

If you want to see the output of your job through email, put your emailid in crontab file.

Example:

14 12 * * * df -k | /usr/bin/mail xxx@xxxx.com 2>&1

This commnd will send output of your system disk space


You can see in unix level also.

login as a root, type mail it will display all emails for root.

Hi Raja

Yes, it is the way to send message of cronjob through email that I already know, however, not every cronjob I will set up to send email because otherwise I will have more than 100 emails to read everyday and I don't think I am capable to finish them all including with other works !!

and as I said, only some of them don't run, but not all of them, and it is a headache of this kind of problem.

/etc/syslog.conf (with the proper settings) and
/etc/default/cron (you should have CRONLOG=YES [the default]
for cron logging) are your friends.

If those don't work you could always put flags in you crontab that write to a file. This will show if the crontab actually runs. I assume you've run any cron scripts manually (make sure you are the proper user) to check that they run right.

Look in /var/cron/log
