User management

Users powers:
As administrative tasks are dangerous and can risk the computer the users can not access to this under normal circumstances.

To do the administrative tasks in the linux and OS based in UNIX there is the root user, and there is also another option that is the sudo powers.

Root User
To access the root user you have to open the Terminal and here we have to enter su, which means 'Super User', after this we have to enter the root password and we are logged in the root user.

For safety as soon as we end doing our tasks we must close session so we do not risk our computer more than we need, also we have to login to our root user only when we really have to do it.

Sudo powers
If our user has administrative powersundefinedwe have to enter at the Terminal and enter sudo su as if we were entering to the root user, but once the Terminal asks us for the password we have to enter our user password instead of the root password. [1] By default the only user with administrative powers is the first user created with the computer, which can give to another users the same powers as it has.
