Hi, I wrote a simple script which is working fine, if I am runing it manually. However when trying to run it as cron, it does not work. Can you suggest why -
Cron is -
12 14 * * *  /operations/services/webapps/8.1/Share/ABC.sh > /home/JoeM/temp/Test.log
Manually I run it under a service account say "MyService tcsh". So, it needs to be run under a service account. How do I do that ?

99.9% of problems with running scripts via cron is forgetting that cronjobs run it a very minimal environment, so if your script relies on certain paths and/or environment variables, you need to ensure they are set in the script.

What user do you currently have the cronjob as?

cron doesn't use any login ENV settings, therefore, it have trouble to run your script.

the workaround is to modify your script to use full path to command
or

use:  su - fred -c command
    use user fred's login env to run the script.

eg:
   12 14 * * *  su - JoeM -c "/operations/services/webapps/8.1/Share/ABC.sh > /home/JoeM/temp/Test.log"

or
12 14 * * *  su - root -c "/operations/services/webapps/8.1/Share/ABC.sh > /home/JoeM/temp/Test.log"
   assume that JoeM's login ENV can run the script.

also have a look at the answer in http:Q_21080002.html

ABC.sh is a simple script, which just runs to other scripts -

#!/bin/sh
./ScriptA.sh
./ScriptB.sh

Also, would I need to to specify password for sudo acceess. So it would be something like
 12 14 * * *  sudo -u JoeM tcsh -c "/operations/services/webapps/8.1/Share/ABC.sh > /home/JoeM/temp/Test.log"

Do you schedule the job as root? If not root then you need to provide password

no, it is to be done as a service account. So, where exactly do I specify password? in the script? how would that work or look like?

where is . when you run ABC.sh?
Do ScriptA.sh or ScriptB.sh depend on the environment?

What you need to do is create a sudo entry that doesn't require a password, eg:

serviceuser   ALL= (joem)  NOPASSWD: /operations/services/webapps/8.1/Share/ABC.sh

then your serviceuser cronjob would look like:

12 14 * * *  sudo -u joem /operations/services/webapps/8.1/Share/ABC.sh > /home/JoeM/temp/Test.log

I think, it is working fine now. It was a typo in the path I was giving. Thanks though
