As, i was practising a few command: I got a root user, and two general users which i created, ie. player1 and player2, both in the same group.
Now, i want to make player1 as the root person too, that is a superuser, so i know the user id of the super user is 0. I was wanting to know the command for changing this? After this, i want to change again the uid and gid of player1 to that of player2. Please help me in my these three quries.
Don't!
Root is root and user is a user. Root is not a 'role' or a 'group' you might be familiar with from windows. Root is a user. If you are player1 now and want to become root (for example to install something), use 'su'. Do your root job and become player1 again (by exiting the su command).
