As one of the earliest operating systems, Linux is becoming more and more popular, and internationally renowned software and hardware manufacturers are allied with it. This is because it has two characteristics as free software: one is to provide source code for free; Second, enthusiasts can freely modify, copy and publish the program source code according to their own needs, and publish it on the Internet. This has attracted experts from all over the world to write various drivers and application software for Linux, making Linux an operating system that is not only a kernel, but also includes system management tools, a complete development environment, development tools and application software, and users can easily obtain it. Because the source code of Linux can be obtained, we can see the internal logic of the operating system, so that we can accurately find out the cause of the failure and take corresponding countermeasures in time. If necessary, users can "patch" Linux in time, which is an advantage that other operating systems do not have. Second, fundamentally speaking, Linux is a variant of Unix system, so it has a series of excellent characteristics of Unix system. Applications on Unix can be easily transplanted to Linux platform, which makes it easy for UNIX users to master Linux.

If the linux group is developed in C, both Linux and unix are platforms developed by C and c++, and the nix system has provided rich development tools for software developers from the beginning. Become the first choice and main operating system and development environment for engineering workstations. It can be said that the emergence and growth of engineering workstations can not be separated from UNIX. So far, UNIX &；; Linux workstation is still the main working platform for software developers and engineering research and design departments. . If you want to develop software or build a server platform, I suggest you use UNIX &；; Linux operating system. UNIX & Compared with the graphical interface, Linux is very safe.
