So in 1984, facing such a closed software creation environment, Richard Stallman launched the GNU source code open plan and formulated the famous GPL license agreement. 1987, GNU project achieved a major breakthrough-the release of ——gcc compiler, which enabled programmers to write their own open source software based on this compiler. Then in the month of 199 1 10, Linus Torvalds, a student of Helsinki University in Finland, wrote an operating system called Linux. Because of its high code quality and open source characteristics based on GNU GPL license agreement, the system has been quickly supported by GNU plan and a large number of hacker programmers. Then Linux system entered the stage of all-round development.
1994 65438+ 10, Bob Young integrated a large number of source code and program software on the basis of Linux system kernel, released the red hat system and began to sell technical services, which further promoted the popularization of Linux system. After 1998, with the development of GNU open source plan and Linux system, many IT giants led by IBM and Intel began to vigorously promote the development of open source software. By the end of 20 17, the Linux kernel has developed to version 4. 13, and there are hundreds of Linux system versions, but the Linux system kernel developed and maintained by Linus Torvalds is still used. RedHat has also become a leading company in the open source industry and Linux system.
