Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX software tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

What can linux be used for?

#To put it simply, basically the functions that you can implement on a computer using the Windows system can also be implemented on Linux. So what is the difference between the two? Let me just talk to you about its advantages compared with the windows system?

1. Linux can see the source code, but windows cannot.

The direct result of this is that you can tailor and customize the required kernel modules for special applications. This is very beneficial for advanced system kernel management optimization and driver development. In addition, because the code is visible, There is no need to worry about malicious functions or backdoors, which is more beneficial for military, government and enterprise use. In addition, when there is a serious problem with the system, you can modify the code yourself or compile it with a patch of a few kilobytes and then use it. However, for Windows, you have to wait for Microsoft's patch.

2. The Linux command line is powerful and can do anything. Windows also has a command line, but it is an accessory.

The command line is the foundation of Linux. Even if you are not satisfied with some commands, you can modify them or make up your own commands. The benefit of the command line is that it's repeatable. To know what exactly the command line is you can visit Old Boy Education. If you want to tell someone how to do something, just send it a command line. If you want to do something you did before again, just call up the historical command record and execute it again. Many things that need to be done regularly are written into scripts, set up a crontab schedule, and that's it. In addition, this also ensures that you use the same command line to do the same thing.

3. Open source and highly customizable

The original intention of open source is not for freedom but for customization. AT&T UNIX has always been copyrighted, but the source code is still available so that users can modify it as needed. Software and systems appreciated by the Linux community mostly follow the same rules - it should be able to adapt to different environments of different users, be able to easily change its behavior, and be able to be easily integrated with different environments. Instead of assuming others have the same needs as yours, give them the freedom to customize the system.

4. Decentralization

Decentralized software development is also destined to have inconsistent system interfaces and forms - because everyone likes to invent the wheel. Everyone's wheel is more or less suitable for themselves and the community, rather than everyone. In the Linux environment, no one can force everyone to use their own wheel (except for Kernel developers, but in fact many distros also have concerns about the kernel. patch), so rather than formulating a practice, Linux allows users to choose how to live.

You will see that there are a large number of distros in the Linux ecological environment. Different distros have different init methods, different package managers and installation strategies; everyone is used to using different VCS and different shells. Different editors are the embodiment of the philosophy of more choices.

5. Linux is based on the network and was born on the network.

By connecting to SSH remotely, you can easily control a Linux server thousands of miles away. As long as you have the corresponding permissions, it is almost the same as sitting in front of a physical machine. Even if the network speed is very bad, it is actually only a few Encrypted characters are transmitted, requiring very little bandwidth.

After reading this, you should have a new understanding of Linux and Windows. Therefore, when you use the operating system as a developer rather than a consumer, you will like Linux more, and now Linux Operations and maintenance is also a popular profession nowadays. If you want to develop in server operation and maintenance, it is good to choose Linux.
