Adn you basically cannot do what you want. Malicious people with root priviledges could break your system. – Basile Starynkevitch Dec 14 '11 at 12:59
@ aix i want to create a two user in a machine. Each user have a permission but they cannot share the data and in case if the OS corrupt but the user cannot lost their data, it found in the another location like the backup drive – user1097810 Dec 14 '11 at 13:00
Do you mean "under the root directory" or users with root privileges? – Paul Dec 14 '11 at 13:14
I'm sorry, but how is anyone supposed to understand anything from this ? What is a user having permission ? On what ? The root home (/root) ? The system's root (/) ? What does "cannot share data" mean ? If the users have permissions on either /root or /, they can share data anyway. Maybe you could try to draw a sketch, or correct your grammar. – Ravachol Dec 14 '11 at 14:47

If you are wanting to give someone root privileges but not give them full access to the system you may want to look at SUDO. The config file is located in /etc/sudoers

Here is a website explaining how to configure sudo: LINK (

This will allow you to define exactly what access and privileges the user can have. Also you should look at user, group, and world permissions with chmod.

Adding users to a group is in /etc/groups

Best of luck!
