Cron

I would like to run a unidata process as a cron using a login other than root. Can this be done from SAM. If not how do I submitt a cronjob as a user other than root. I have a script that will login to unidata and run my process but when tring to add as a cron in SAM I get error because I a root and unidata does not recognize root.

Hi,

If you want to run this job as root try to do a su as the user who is allowed to run thisjob,

cron_schedule su - allowed_user -c "unidata_job_with_path"

Hope this helps.

Hi Gabriel,

edit the /var/adm/cron/cron.allow

su - user

crontab -e

You need to add the user "unidata" to /var/adm/cron/cron.allow. Afterwards, you can then su - unidata and use the crontab command to read in your cronjobs for that user.

If you want to edit a crontab entry later for this user then su - unidata,
crontab -l > unidata_cron # unloads current entries
vi unidata_cron and make your changes
crontab < unidata_cron # reload the crontab
will

Hi Gab,

the easiest way is edit crontab for another user

su - user

crontab -e

2 * * * * $PATH/script.sh

contab -l displays submitted jobs

dont forget for env setting in your script, because cron doesn't use profile

Hi Gabriel,

do "man crontab" to find what is neccessary for a user to run his own cron job. You can allow the user to run his own cron job and setup the cron job for that user.

Hope this helps.

This needs to be run as a root user but you want cron as other than root user?

SUDO can be very useful for this situation. Call cron as the unidata user, in the sudoers file you have the unidata user allowed to run this script as root, and the cron script makes a sudo unidata script" call.
