What is a Linux server?
What is a Linux server?, The operating system is at the center of the possibilities of today’s technology in terms of software. Not only computers but also many different electronic devices have operating systems. The operating system, which enables all the basic features of the device to gain functionality, has different software and interface features such as Microsoft Windows, macOS X and Linux, especially for computers.
One of the most functional of these operating systems is Linux. But before mentioning the working principles and history of Linux, it is necessary to express what the operating system is in general terms and why its use is important. For this reason, it may be useful to explain the features that Linux promises after making a description of the operating system and making a detailed introduction to its functions.
The operating system can be expressed as a set of software that manages hardware resources and provides commonly used services for different applications. Application codes in the operating system are largely executed directly by the hardware. In addition, the operating system acts as a bridge between applications that control hardware features such as input output and memory allocation and the computer.
When the hardware is considered as the central element of the communication network, the operating system becomes the part that provides the mediation of the command to be given to the hardware without applying to the application. As a matter of fact, it is considered a healthier software approach to evaluate any operating system not with the breadth of its functionality, but with the capacity to program the command transmitted by the user for a specific purpose.
Operating systems are used not only in computers, game consoles, mobile phones and internet servers, but also in cars, white goods and watches. In the 1940s, no electronic device had an operating system, but after the discovery of the programmable computer, the creation of binary number (0 and 1) machine language represented an important first step for operating system technologies.
Operating systems that enable electronic devices to perform their functions come in several different types. Operating systems with real-time, single-user, multi-user, single-task, multi-tasking, distributed, and embedded types of operating systems differ according to their installation, location, software features and interface types. Linux is among these operating systems.
What is Linux?
Linux is one of the core software that is an essential part of computer operating systems. Linux, which is a variant of the freely distributable, multitasking and multi-user UNIX environment, is mostly preferred by IT professionals today. Using open source codes as well as having free distribution, Linux makes it possible to be reprogrammed and developed by users.
Linux, which is an operating system without any cost, can be used easily in many different devices, especially IBM and PC compatible computers. The development of Linux is open to all internet users around the world, which makes it easier to detect and correct system errors. The development system of Linux can be expressed evolutionarily thanks to this feature.
Linux from Past to Present?
Linux was developed in 1991 by Linus Torvalds, a Finnish university student. In this operating system, which is produced from scratch in the software environment of UNIX, there is no code taken from there. In 1992, Linus Torvalds released this self-developed operating system as free software under the GNU Public License to get the support of more developers and users. Thus, Linux and GNU complement each other’s shortcomings and become a complete operating system that can be shared with users. Linus Torvalds’ choice of GNU Public License is a critical point for Linux. Because Linux has managed to get the contribution of many volunteer IT experts around the world, which positively affected the development process of the operating system.
What are the Features of Linux?
The most important feature of the Linux operating system is that it is open source and it is completely free or can be purchased for a very low price. This is a great advantage because the approach that enables Linux to be free also makes the programs to be used in the operating system free. It is also very resistant to Linux system errors.
The fact that it does not crash easily stands out among the reasons why users prefer Linux. It keeps your Linux computer running smoothly even when you run several different programs at the same time. Linux text editors, which are very successful in preventing system errors, meet many different needs such as drawing software, spreadsheets and databases.
Linux Operating System Used In Which Projects?
The Linux operating system is specially prepared for many different projects. Linux, which cognition experts prefer to use while developing the software of high-performance programs, makes it possible to work on a computer with more than one processor and increases efficiency. Linux offers the best user experience in projects using graphical data analysis software or fractal creation software.
How to Install Linux?
To install Linux, you first need to burn the Ubuntu Linux ISO file on a USB stick or DVD. After completing the burning process, you can start the Linux installation via USB or DVD. The important point here is to pay attention to the different Linux installation types. If your computer has a Windows operating system, you can install Linux next to it very easily.
However, while installing Linux, you also have the option to uninstall Windows and run Linux only. You can also wipe the disk, use ZFS, and try a different installation. After making settings such as location, keyboard and internet connection, you can create your profile and complete the installation of Linux. Ubuntu allows you to create ISO files that make Linux installation easier.
Most Used Linux Commands
Pwd command: This command allows you to find which directory you are in. It reveals the exact location of the file you are looking for within the operating system. In this way, you do not waste time searching any file. Starting with the location (/) sign, / home / username is an example.
Cd command: You can use the cd command to navigate the Linux file system. For example, when you want to go to the photos, which is a subdirectory of the documents from the directory named / home / username / Documents, it is enough to enter the cd photos command.
Is command: This command used to view the contents of a directory is used with the location of the directory. When using this command for viewing content, all you have to do is enter the location of the folder you want to view. For example Is / home / username / Documents can enable you to do this.
Cat command: One of the frequently used commands, cat command is used to see the contents of a file in the standard output (sdout). To use this command, you have to type cat and then the file name and extension. Example: cat filename.txt
Cp command: The cp command used to copy files from the current directory makes a copy of any file you want. cp sample.png / home / username / Pictures command is making a copy of the sample.png file in Pictures directory for you. The cp command is among the most functional commands.

Mv command: This script is used to move and rename files. When using the mv command, which is very similar to the use of the cp command, you first type mv and then specify the filename and destination directory. Example: mv file.txt / home / username / Documents
Mkdir command: This command for creating a new directory is among the most useful commands. When you need a new directory where you will put your files, it is enough to enter the mkdir Muzik command to create the directory named Muzik.
Rmdir command: This command makes it easy to delete directories, unlike mkdir. The only difference is that the rmdir command only allows you to delete empty directories. For example, if your Muzik directory is empty, you can easily delete this directory when you enter the rmdir Muzik command.
Rm command: Unlike the rmdir command, it helps you delete directories that contain files. If you want to delete a directory with the files in it, the rm command allows you to make the changes you have planned on the operating system. Example: rm Music
Touch command: The touch command, which allows you to create new empty files via the command line, is among the basic Linux commands. For example, if you want to create an HTML file named Web under the current Documents directory, simply enter the command touch /home/username/Documents/Web.html.
