Script not runing from cron
 

Dear all,

Linux RHEL 5 ES

We have the below entry in the cron

00 08 * * * sh /scripts/Shrink_MSM_ROM_RAT.sh > /scripts/Shrink_MSM.log

when am running it manually it works fine, but not from the crom. Folder /scripts readable and writable by all the users

Please advise

Kai

In addition to the above, crond is running too .Tried the below too

* * * * * env > /tmp/env.output

not working

Anything about cron in the system logs, or in e-Mail to the owner of that cron-tab entry?

Do you have a blank line between your command and the end of the crontab? I've noticed before on my systems that if there isn't a blank line after the last cron entry, it won't run.

Thanks Cronlog shows only the below

NO There is no blank line .

And mail?

crontab entries run in a special environment, so maybe sh and env cannot be evaluated. Check PATH variable, or try to use full path:

Is that the full path to the script you are trying to run? Are there any relative paths or variables in the script itself which would make sense when you manually run the script but not so much when the script is run by cron? I have found in the past when a job like this fails it is because the script runs OK under my login but it contains shortcuts or variables which are specific to my login and are not available to cron

I have had to change working directory on stuff like this before. This may help it may be redundant. I would also capture error stream with 2>&1.

00 08 * * * cd /scripts && /usr/bin/sh Shrink_MSM_ROM_RAT.sh > Shrink_MSM.log 2>&1

Thanks , Issue resovled . if am scheduling the cron after 5 minutes from the system time, it works fine.. not immediately. Am sure it doesn't make sense. but it works like that.

Thanks to all

Kai

Hi Kai,

I'm having the same issue. Would appreciate if you post a sample entry of before and after you got it working.

Thanks!
