Hi Friends

Just wanted to know that in which script it is mentioned that Root should have all the privileged of read write and execute???

Any idea ????

I don't understand your question. It could be me, but I'd recommend you read the Welcome to LQ link to see if there's a better way to phrase the question.

There is no script that gives root its privileges. Any user with a user ID of 0 is automatically superuser; this is built into UNIX and Linux.

Hi berndbausch,
Is it possible to change the user ID of normal user to '0', And What will happen if we do that?

During installation Root has the access to make changes according to the requirements so where it is mention that Root should have UID=0 or it \
is super user that's my point

man usermod:

Code:

       -u, --uid UID
           The new numerical value of the user's ID.

           This value must be unique, unless the -o option is used. The value
           must be non-negative.

           The user's mailbox, and any files which the user owns and which are
           located in the user's home directory will have the file user ID
           changed automatically.

           The ownership of files outside of the user's home directory must be
           fixed manually.

           No checks will be performed with regard to the UID_MIN, UID_MAX,
           SYS_UID_MIN, or SYS_UID_MAX from /etc/login.defs.

I don't know if it's a good idea to change the UID of an existing user to 0, but you can create a new user, give it the same home directory as root and set its UID to 0. useradd also has the -u option.
