How to switch to root user?

To switch to the root user in a Linux environment, you can use the su command. Here’s how to do it:

Open your terminal.
Type the following command:
```
su -
```
If prompted, enter the root password. Since the context indicates that no password is set for the root user, you may not need to enter a password.

Alternatively, if you have sudo privileges, you can switch to the root user using:

sudo su -

This command will elevate your privileges to root without needing to enter the root password, as long as your user has sudo access.
