    Ubuntu is one of the most widely used Linux distributions. It can be employed for a variety of tasks, such as hosting, education, and learning. In this article, we will go through the Ubuntu Operating System explanation.

    We'll start with a few technical terms to help you differentiate between a Kernel and an Operating System. We'll look at 5 example commands later to see how Debian works. Let's get started.

    What is Kernel?

    The kernel is the most crucial component of the operating system software collection. In an operating system, it is the software that does all of the hard liftings. It is in charge of the hardware, timing, peripherals, memory, drives, user access, and everything else that happens on a computer. It determines when software should execute and what rights should be granted to it.

    Moreover, it ensures that no software accesses memory that is not its own and that no program crashes other programs. It splits the time for processes to utilize the CPU and performs almost a hundred other tasks.

    Then there's something called a shell. A shell is the component of an operating system with which you interact as a user. It is a user interface designed to allow users to connect with the Kernel. There are both command line and graphical user interface shells. The OS is the name given to the combination of these plus a few additional pieces of software.

    What is Linux distribution?

    Linux distributions are essentially operating systems that are built around the Linux kernel. The user can select a distribution that best matches their needs. If the user is new to Linux and has never used a distribution before, he or she should start with Ubuntu or Linux Mint.

    Rolling release distributions, such as Arch Linux, can be used if the user requires a distro that always contains the most up-to-date software. Some distributions are also task-specific. Distros such as Kali Linux and Parrot Linux are primarily intended for penetration testing and security-related tasks.

    What is Ubuntu?

    Ubuntu is a free and open-source Linux distribution that is derived from Debian. It is developed and sponsored by "Canonical Ltd." and is regarded as a suitable distribution for newcomers. Although the operating system was designed primarily for personal computers (PCs), it may also be deployed on servers.

    The term "ubuntu" comes from the Zulu language of Africa and means "humanity to others." GNOME is Ubuntu's default desktop environment. GNOME's Graphical User Interface (GUI) makes it simple to interact with Linux-based distributions (GUI). The default package manager of Ubuntu is “apt-get”. Operating systems use package managers to install and update the packages in the machine.

    Ubuntu Commands Examples

    A “command” is a utility in the Ubuntu operating system. Commands can be used to perform both basic and complex actions. The Linux terminal is used to carry out these instructions. Any administrative activities may be completed via the terminal. Package installation, file manipulation, and user management are all supported. Let's look at 5 popular Ubuntu commands to check if it works.

    The touch command is required for creating a valid empty file under Linux. You can create files in your terminal on the go and fill them up later or in real-time, depending on your needs.

    rm

    This command is used to remove a file from your system. Using -i option with the command prompts the user before deleting the file.

    cd

    The cd command is known as the “change directory” command in Linux. It's used to change to a new working directory.

    file

    The file command is used to determine the type of the file.
