How to become root user?

To become the root user in a Linux system, you can use one of the following methods:

1. Using su Command:

   • Open a terminal and type the following command:

     su -

   • You will be prompted to enter the root password. After entering the correct password, you will switch to the root user.

2. Using sudo Command:

   • If your user has sudo privileges, you can execute commands as the root user by prefixing them with sudo. For example:

     sudo command

   • To start a root shell, you can use:

     sudo -i

   • You may be prompted to enter your user password (not the root password).

3. Using sudo su Command:

   • You can also combine sudo and su to switch to the root user:

     sudo su -

   • This will give you a root shell without needing the root password, as long as your user has sudo privileges.

Make sure to use root privileges responsibly, as actions taken as the root user can significantly affect the system.
