Linux is an open-source operating system for servers, computers, mobile devices, as well as embedded devices. It is supported on almost every computer platform. As a result, it makes a widely used operating system. However, most users might think Linux is a complex operating system. It is because they may think Linux is just for programmers. However, the more you learn about Linux, the more it turns out that it’s not that complicated. Especially learning simple Linux commands will make it easier for anyone to use it
When Linux launched in 1991, it started to attract attention with its open-source structure. It has gained popularity each day since it was released. People are free to make changes and then distribute them with their names.
To run Linux you need to use a shell that gives you access to the operating system. The shell is an interface that helps you control Linux. Most Linux shells have a graphical interface (GUI). It is mainly about further making the user experience better. It is well used when managing a VPS.
Since it is very effective users recommend using a command-line interface (CLI). With GUI, tasks that required a multi-process can be done in a few seconds.
You might be wondering about Linux now but need more to know about Linux commands. In this article, you will find some Linux commands that will help you use Linux both easily and effectively.
What Is A Linux Command?
It is a program that runs on the command line. The command line is an interface, the text that turns into instructions. The graphical user interface is an abstraction of the command line. A flag is a pass option to command that you are running. Most Linux commands give a help call with the flag -h.
The parameter is the input that we give the command, it will help this work. The argument can be anything you type in the terminal, but most often it is a file path. You can call flags with hyphens (-) and double hyphens (–)
Simple Linux Commands
