How to login to root in linux

Logging in as the root user in Linux is generally discouraged because it grants you full administrative privileges over the entire system, which can be risky if you’re not careful. It’s better to use the sudo command to perform administrative tasks as needed. However, if you have a legitimate reason to log in as the root user, here’s how you can do it:

Method 1: Using the Terminal

1. Open a terminal window.
2. Type the following command and press Enter:

   $ sudo su –

   This command will prompt you for your user password. Enter it.

3. If you entered the correct password, you will now be logged in as the root user, and the terminal prompt will change to root@yourhostname:~#. You have full administrative privileges, so be very cautious when making changes.

    

   Method 2: Using the “su” command

   1. Open a terminal window.
   2. Type the following command and press Enter:

      $ su
      You will be prompted to enter the root password.

   3. Enter the root password, and if it’s correct, you will now be logged in as the root user.

      Again, it’s essential to use these commands with caution, as any mistakes or misconfigurations while logged in as root can have severe consequences for your system’s stability and security. It’s generally recommended to use the sudo command for specific administrative tasks rather than logging in as the root user. After you’re done with administrative tasks, you should exit the root session by typing exit and pressing Enter, or simply closing the terminal window.
