I store a website on redhat and using drupal.
There is a button on the site that activates a php script and that php script use exec to activate bash script on the server.
Right now the script is not being run, i guess because of permission reason - the drupal user that runs the bash does not have root access to run the bash script.
How can i add the user as a root and test this ? and then to downgrade it to normal level.
So what i need to know - how to view current users, groups, and status, and changing them.
Is this recommended ? I am not linux expert.
