Well, it is the operating system or the kernel which does this work. So, to work on your computer, you need an Operating System OS. In fact, you are using one as you read this on your computer. Linux is an operating system or a kernel which germinated as an idea in the mind of young and bright Linus Torvalds when he was a computer science student.
However, when his suggestions were rejected by the designers of UNIX, he thought of launching an OS which will be receptive to changes, modifications suggested by its users. So Linus devised a Kernel named Linux in Something as you have a cone but no ice-cream on top. As time passed by, he collaborated with other programmers in places like MIT and applications for Linux started to appear.
So around , a working Linux operating system with some applications was officially launched, and this was the start of one of the most loved and open-source OS options available today. The earlier versions of Linux OS were not so user-friendly as they were in use by computer programmers and Linus Torvalds never had it in mind to commercialize his product. Nonetheless, the open-source aspect of the Linux operating system made it more robust. The main advantage of Linux was that programmers were able to use the Linux Kernel to design their own custom operating systems.
Now, Linux is one of the most popular and widely used Kernel, and it is the backbone of popular operating systems like Debian, Knoppix, Ubuntu, and Fedora. Nevertheless, the list does not end here as there are thousands of Best versions of Linux OS based on the Linux Kernel available which offer a variety of functions to the users.
Richard Stallman. Its main benefits are —. It offers a free operating system. This gives you in order : the kernel name, the version of the kernel, and the type of hardware the kernel is running on. In this case, the kernel is Linux version 4. More information about the uname command can be found by running man uname. This file provides information about a distribution including, but not limited to, the name of the distribution and its version number.
The os-release file in some distributions contains more details than in others, but any distribution that includes an os-release file should provide a distribution's name and version. As the example above shows, Fedora's os-release file provides the name of the distribution and the version, but it also identifies the installed variant the "Workstation Edition". There are, however, additional tools that can provide you a report about your system.
The screenfetch and neofetch commands give a verbose overview of your system, with details about your kernel, architecture, available RAM, CPU speed and core count, desktop version, and so on. The hostnamectl command is available on most modern Linux distributions. If it's not already installed, you can install it from your software repository.
Despite its humble name, it provides far more than just your hostname;. Some desktop environments offer similar system reporting tools. For instance, the KDE Plasma desktop provides KInfoCenter, which can tell you everything from your kernel and architecture to your available network interface cards, IP address, and much more.
Regardless of what tool you decide to make your default, getting the version and features of your OS is a seemingly simple but important skill. Remember these tips so the next time you need to see what you're running, you'll know several places you can find out. This article originally published in and has been updated by the editor with additional information.
For those who prefer a nice UI and use a Plasma desktop! To install this using apt-get, the command would like like this:. The sudo command is added because you need super user privileges in order to install software. Similarly, to install the same software on a Fedora-based distribution, you would first su to the super user literally issue the command su and enter the root password , and issue this command:.
Still in doubt? Recall the Easy Lamp Server Installation from earlier? With a single command:. It really is that easy. With Linux you can assure your desktops will be free of trouble, your servers up, and your support requests minimal.

What is Linux? Here is all the information you need to get up to speed on the Linux platform. The Linux operating system comprises several different pieces: Bootloader — The software that manages the boot process of your computer.
For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system. Kernel — This is the one piece of the whole that is actually called? The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the lowest level of the OS. Init system — This is a sub-system that bootstraps the user space and is charged with controlling daemons.
One of the most widely used init systems is systemd? It is the init system that manages the boot process, once the initial booting is handed over from the bootloader i. Daemons — These are background services printing, sound, scheduling, etc. Graphical server — This is the sub-system that displays the graphics on your monitor.
It is commonly referred to as the X server or just X. Desktop environment — This is the piece that the users actually interact with.
