Crontab for pkexec as root
 

Hello everyone,

I am trying to schedule a script through cron. This script utilizes pkexec for running a command. I as a user am able to run the command with pkexec for root. But when I schedule it through crontab then I keep getting the error Error executing command as another user: Not authorized. Please help.

Haven't used pkexec but after looking at it I'm not sure you need it.

We often run commands as other users from root's crontab by doing something like:

This tells it to run the script called myscript.pl as the user, myuser, instead of as root.

Thank you for the response.

The issue am facing is that when am trying to run my script without cron, in this manner
su - abhishek -c "/path/to/script" then its asking me password. Does that mean it shall keep
popping some GUI for the password every time it tries to run the script. That's not what I need.
I wanted it to run in background!!!

As MensaWater pointed out, you use that technique from the root's(!) crontab; root doesn't require a passwd to login & run a cmd as another user.
You can try it by using 'su -' to get root and then run the cmd manually.
(If you're on ubuntu, I believe it's 'sudo su -')
