Prerequisites
Commands in Linux

Linux has become an extremely popular operating system in recent years. It is a free, reliable, and secure system that is utilized for a variety of applications, including web servers and clusters for scientific computing. Linux's command-line interface enables users to interact with the system more effectively and powerfully than through a graphical user interface. It is open-source and similar to the Command Prompt application in Windows.

In this article, we will discuss the fundamentals of Linux commands, as well as some of the most popular Linux commands with their syntax and their usage.

Prerequisites

Before we move on to exploring the Linux commands there are a few prerequisites that should be taken care of:

Understanding of the command-line interface: As Linux commands are entered into a command-line interface, it is important to have a basic understanding of how to use it. This includes knowledge of how to navigate the file system, how to enter commands, and how to view the output.
Basic knowledge of Linux: Although these commands can be used on any Linux distribution, it is helpful to have a basic understanding of the Linux operating system. This includes knowledge of the file system structure, file contents, basic commands, package manager, and system administration. Linux has various package managers available in its system.
Access to a Linux system: In order to use these commands, you need access to a Linux system. This can be a physical machine or a virtual machine that is running Linux. There are also online platforms and virtual environments available that provide access to a Linux system.
User permissions: Depending on the command you want to run, you may need administrative privileges or root access. This can be granted by using the "sudo" command or logging in as the root user. You may also need file permissions before modifying them.
Familiarity with text editors: Some commands require the use of a text editor to edit configuration files or create scripts. It is helpful and important to have a basic understanding of text editors such as vi or nano.
Internet connectivity: These commands often require the installation of packages or updates. It is helpful to have internet connectivity to access the repositories and download the required files.

Commands in Linux

Linux commands are text-based instructions that can be used to interact with the Linux operating system. They are typed in the terminal or command-line interface and are used to perform a variety of tasks.

Most Linux commands follow a similar syntax, which consists of the command name followed by options and arguments. Options modify the behavior of the command, while arguments specify the input to the command. Many Linux commands have a help option that can be accessed by appending --help or -h to the command, which will display a list of available options and their usage.
