Depends how you have cron authorization configured. If you have a /var/adm/cron/cron.allow file, you need to add the enw username to it before it will be allowed to run cron jobs. If you don't have one, but have a /var/adm/cron/cron.deny file, then the new username will be able to run cron jobs unless you add it to the cron.deny file. If neither file exists, only root can run cron jobs and your will need to create /var/adm/cron/cron.allow with the new username as an entry.

(I think I remembered all that correctly. :) )

ps -ef will show you all the processes on the system

cd /var/spool/cron/crontabs
create a file named for the user with the appropriate entries (you can model it after one of the other files in the directory.

log on as the user and run crontab /var/spool/cron/crontabs/new_cron_tab_file to activate the new file

Hi:

To configure the ability for a user to use cron, add the users login name to 'var/adm/cron/cron.allow'. See the 'crontab(1)' manpages for more information regarding this.

To see what processes are running on a system, use 'ps' or 'top' or 'glance'.

'ps' is easily scripted and offers a wide ability to select processes by various criteria and the amount of information returned about them.

# ps -ef

...shows all processes

# ps -fu

...limits the process information returned to processes belonging to .
