What is Linux?

Linux, developed by Linus Torvalds in 1991, is an open-source operating system that forms the base for diverse computer systems. Over the years, Linux has evolved into a robust and extensively adopted operating system. What distinguishes Linux is its exceptional attributes of flexibility, stability, and security.
Linux operates based on the Unix-like architecture, offering a command-line interface (CLI) where users can interact with the system through text commands. However, Linux also provides graphical user interfaces (GUIs) that resemble those found in other operating systems, making it accessible to users of different technical backgrounds.
Linux’s remarkable strength lies in its rich distribution ecosystem. Various organizations and communities have contributed to the development of their own Linux distributions, including well-known ones like Ubuntu, Fedora, Debian, and CentOS. This diversity in distributions allows users to choose the one that best aligns with their preferences and requirements. Each distribution may have its unique features, package management systems, and user interfaces, while sharing a common Linux kernel.
Linux is known for its robustness, scalability, and versatility. It powers a wide range of devices, from servers and supercomputers to smartphones, embedded systems, and IoT devices. It supports a vast array of software applications and has become the backbone of many technological advancements and infrastructure worldwide.
Overall, Linux offers users a powerful and customizable platform that encourages collaboration and innovation, making it a popular choice for both individuals and organizations seeking a reliable and efficient operating system.

What are Linux Commands?

Linux commands are text-based instructions that allow users to interact with the Linux operating system. They are entered into the command-line interface (CLI) or terminal to perform a wide range of operations, including managing files, directories, processes, networking, and system configurations.
Linux commands typically follow a specific syntax, consisting of the command itself followed by options and arguments. Options modify the behavior of the command, while arguments provide specific inputs or targets for the command to act upon.
Here are a few examples of commonly used Linux commands:

ls: Lists files and directories in the current location.
cd: Changes the current directory.
mkdir: Creates a new directory.
rm: Removes files and directories.
cp: Copies files and directories.
mv: Moves or renames files and directories.
grep: Searches for a specific pattern in files.
chmod: Changes the permissions of files and directories.
sudo: Executes a command with administrative privileges.
ping: Tests network connectivity to a specific host.

These are just a few examples, and there are numerous other commands available in Linux, each serving a specific purpose. Linux commands provide a powerful and flexible way to control and manage the operating system and perform a wide range of tasks efficiently.

Top Basic Linux Commands for Beginners

For beginners, it is helpful to start with the following three basic Linux commands:

The “ls” command

The ls command is frequently employed to discover the contents of the current working directory, including files and directories. It is among the essential Linux commands that are highly useful to familiarize yourself with.
Executing the “ls” command without any additional arguments provides a detailed output containing comprehensive information about the files and directories in the current working directory. This command offers flexibility in displaying data in the output. Please refer to the visual representation below for a better understanding.

The “cd” command

The “cd” command is utilized to traverse through directories in the Linux system. Depending on the current working directory, you can provide either the full path or the directory name as an argument. Running the command without any options takes you to your home folder. It’s important to note that the “cd” command can only be executed by users with sudo privileges.

Command:

Output:

In the given example, we first used the “pwd” command to view the current directory as a reference. Then, we executed the “cd GeeksforGeeks” command to switch to the “GeeksforGeeks” directory. By using the “pwd” command again, we can verify that the output reflects the switched directory, which in this case is “GeeksforGeeks.” The “cd” command allows users to navigate the directory structure and move to different directories within the Linux system.

The “mkdir” command

The “mkdir” command provides a convenient way to create new directories directly in the terminal. Its default syntax is “mkdir ” to create a new directory.
For instance, if you want to create a directory named “GeeksforGeeks,” you can use the basic syntax as follows:

Suppose you want to create an additional directory called “projects” inside the main directory “GeeksforGeeks” to store your projects. In that case, you can use the following command:

This command will create the “projects” directory as a subdirectory within the “GeeksforGeeks” directory. With the “mkdir” command, you can easily create directory structures and organize your files in a hierarchical manner on the Linux command line.
