To execute a command as a superuser (root) in Bash, you can use the sudo command.
Open your terminal or command prompt.
Type sudo followed by a space.
Append the command you want to execute as a superuser.
For example, to install a package using apt-get as a superuser, you can use:
sudo apt-get install <package-name>
Alternatively, you can also open a root shell using the sudo -s command. This will give you a root shell prompt where you can execute multiple commands as a superuser. To exit the root shell, simply type exit.
Please note that executing commands as a superuser should be done with caution, as it grants unrestricted access and can potentially harm your system if used incorrectly.
