Cron job not running

yabhi_22 · #1 (**permalink**) 07-03-2009

Hi All,

I am editing crontab using -e option to add a new job
Below is the line
30 * * * * scriptpath

This job is not executing every thirty minutes.
I have checked, cron daemon is running.
What did I miss? Can some one help?
I am using cron shell..ksh

A good place to start.

Ok. For a cron job the required profile must be set so that the script executes.
Now how do we tell cron that it has to execute the script with this profile

a variation of.......

Code:

30 * * * * . ~/.profile && scriptpath

Is not true.

Not loading the .profile does not "stop" a cronjob from executing. It may be that without it the job will not work, but that's not the same thing.

If your script produces output it will (normally) go to your mailbox if it's set up. Check your mail to see if there are any errors.

A common cause (apart from the daemon not running) of cronjobs not running is that too many jobs are running and new jobs are queued up and the daemon can't start them

Code:

/var/log/cron
or
/var/adm/log/cron
or
somewhere else depending on your OS

should report if this is the case.

I checked /var/log/cron there are no logs being generated. My script itself has its own log. Even its not being created. I am not sure what going wrong.How do I debug whether a cron job is executing or not?

You never said if you were able to run the job manually.

Can you show the actual crontab entry?

can you also...

Code:

cd /where/my/script/is
ls -l script_name
ksh -n script_name

Thanks.
