Linux is an open-source, Unix-like operating system based on the Linux kernel , which was first released on September 17, 1991, by Linus Torvalds. It is typically packaged as a Linux distribution (distro) , which includes the kernel and supporting system software and libraries. Many Linux distributions use the word "Linux". Linux is widely used in servers, desktops, laptops, mobile devices, and other embedded devices. It is also the leading operating system on supercomputers and is used in many other applications, such as routers, automation controls, and home appliances. Android's Linux kernel is based on the open-source Linux kernel, which is modified and customized by Google and other companies to meet the specific needs of the Android platform.

What is Linux distribution ?

A Linux distribution (distro), is an operating system made from a software collection that includes the Linux kernel and various other software packages. Linux distributions, which are available for a wide variety of systems ranging from embedded devices (for example, OpenWrt) and personal computers (for example, Linux Mint) to powerful supercomputers (for example, Rocks Cluster Distribution).
There are numerous Linux distributions available, each with its own unique features, strengths, and user interfaces. Some popular options include Ubuntu, Debian, Fedora, openSUSE, and Linux Mint.

• Ubuntu : A user-friendly and widely used distribution based on Debian.
• Fedora : A cutting-edge distribution that always includes the latest software packages.
• CentOS : A popular distribution for servers and enterprise environments based on Red Hat Enterprise Linux.
• Arch Linux : A lightweight and highly customizable distribution that requires more technical expertise to install and maintain.
• openSUSE : A stable and feature-rich distribution with a easy-to-use installer and a large community of users and developers.
• Lubuntu : A lightweight distribution that is designed to be fast and efficient, ideal for older hardware.
• Linux Mint : A user-friendly distribution that is designed to be easy to use and provides a more polished user experience.
• Manjaro : A user-friendly distribution that is known for its ease of use and access to the latest software packages.
• SteamOS : A Linux distribution specifically designed for gaming and entertainment .
• Puppy Linux : A very lightweight distribution that can run on older hardware and is ideal for netbooks and older computers.

Command Line Interface

The command line interface (CLI) is a text-based interface that allows users to interact with a computer by typing commands. It is a powerful and efficient tool for interacting with Linux systems. It gives users more control over their systems and allows them to perform tasks that are not possible with a graphical user interface (GUI).
The CLI can be used to run applications, install software, and manage your system. It is also a good way to troubleshoot problems and automate tasks.

If you are new to the Linux, it is a good idea to start by learning the basics of the CLI.

Reason to Learn Command Line Interface ?

• Gives you more control over your Operating System .
• Allows you to perform tasks that are not possible with a graphical user interface (GUI).
• Auditing and Debugging is Easier.
• perform tasks much faster than using a graphical user interface (GUI).
• Better understanding of how your computer works.
• CLI is a lightweight interface, requiring fewer system resources than a GUI.

If you are new to the Linux, it is a good idea to start by learning the basics of the CLI.
Learning a command line interface (CLI) can seem intimidating at first, but it's actually quite straightforward and can be a valuable skill to have.

• Unfamiliar territory: Many people are used to graphical user interfaces (GUIs) and may find it challenging to switch to a text-based interface.
• Steep learning curve: CLI requires a different set of skills and knowledge than GUIs, and it may take time to learn the basic commands and syntax.
• Fear of making mistakes: Users may worry about making mistakes or typing the wrong commands, which could potentially cause harm to their system.
• Lack of visual feedback: CLI does not provide the same level of visual feedback as GUIs, which can make it harder to understand what's happening.
