In Linux, there are different user accounts that can be used to log in to the system. Two of the most important user accounts are Root and Sudo. In this article, we will explore what Root and Sudo are, their differences, and how they are used in Linux systems.

What is Root?

Root is the highest level user account in a Linux system. It is also known as the “superuser” account. The Root user has complete access to all files and directories on the system, and can perform any action that is possible on the system. This includes the ability to modify system settings, install software, and delete files.

The Root user account is created during the initial installation of the Linux distribution, and the password for the Root account is usually set to a blank or an empty string. This means that no password is required to log in as Root, and anyone who has access to the system can become the Root user.

What is Sudo?

Sudo is a utility that allows users to perform actions with the privileges of the Root user, without actually logging in as Root. The name “sudo” comes from the Latin phrase “sudo nomine,” which means “to be able to give.” Sudo allows users to give themselves temporary Root privileges for specific tasks, and then return to their original user account after the task is completed.

Sudo was created to provide a way for users to perform administrative tasks without having to log in as Root, which can be dangerous due to the high level of access and power that Root provides. Sudo allows users to perform administrative tasks with less risk of causing damage to the system.

Differences between Root and Sudo

There are several key differences between Root and Sudo:

• Access: Root has complete access to all files and directories on the system, while Sudo only provides temporary access to specific tasks.
• Password: Root does not require a password to log in, while Sudo requires a password for each task that is performed.
• Risk: Root provides high-level access to the system, which can be dangerous if not used properly. Sudo, on the other hand, provides temporary access and reduces the risk of causing damage to the system.

How to use Root and Sudo

To use Root or Sudo, you will need to have an account on the Linux system. Once you have an account, you can log in as Root by simply typing “sudo” followed by the command that you want to run. For example:

sudo ls -l /

This command will list the files and directories in the root directory of the system, using the privileges of the Root user.

To use Sudo, you can type “sudo” followed by the command that you want to run, and then enter your password when prompted. For example:

sudo apt-get install firefox

This command will install the Firefox web browser on the system using the privileges of the Root user.

Conclusion

In conclusion, Root and Sudo are two important user accounts in Linux systems that provide different levels of access and power to users. Root is the highest level user account with complete access to all files and directories, while Sudo provides temporary access to specific tasks with less risk of causing damage to the system. Understanding the differences between Root and Sudo can help you use them effectively and safely in your Linux system.
