The birth of the Linux operating system

Founder Linus Torvalds

, the development and growth process has always relied on five important pillars: the UNIX operating system, the MINIX operating system, the GNU Project, the POSIX standard and the Internet.

1981 IBM introduced the IBM PC, a microcomputer.

In 1991, GNU project had developed many tools and software, the most anticipated GNU C compiler had appeared, GNU operating system core HURD has been in the experimental stage, no availability, in essence, did not develop a complete GNU operating system, but GNU laid a foundation for Linux user base and development environment.

In early 1991, Linus Torvalds began learning the MiniX operating system on a 386SX-compatible microcomputer. In April 1991, Linus Torvalds began to incubate and build his own operating system.

On April 13, 1991, comp.os.minix released that he had successfully ported Bash to minix and was unable to leave the shell.

On July 3, 1991, the first linux-related announcement was made on comp.os.minix (there was no Linux yet, of course, and Linus Torvalds probably had FREAX in mind. FREAX means grotesque, monster, whimsical, etc.).

October 5, 1991, Linus Torvalds officially announces the creation of the Linux kernel (Freeminix-likekernel Sources for 386-AT) in a post on the comp.os.minix newsgroup.

In 1993, there were about 100 programmers writing/modifying the Linux kernel, with a core group of five people. At this point, Linux 0.99 had about 100,000 lines of code and about 100,000 users.

In March 1994, Linux1.0 was released with 170,000 lines of code under a completely free and free license, followed by the adoption of the GPL.

In January 1995, Bob Young founded RedHat (little RedHat), which was marketed as a Linux” distribution “based on GNU/Linux and integrated more than 400 open source program modules. This is a pioneering business model.

In June 1996, the Linux 2.0 kernel was released, which had about 400,000 lines of code and could support multiple processors. At this point, Linux has entered the practical phase, and is used by about 3.5 million people worldwide.

In February 1998, a group of young “old GNU core” led by Eric Raymond finally realized that the nature of the GNU/Linux industrialization path was driven not by liberal philosophy but by market competition. Founded the banner of “Open Source Intiative” (Open Source Promotion Association) “revival”, launched a historic Linux industrialization movement in the Internet world.

In January 2001, Linux 2.4 was released, which further improved the scalability of SMP systems and integrated many of the features used to support desktop systems: USB, PC card (PCMCIA) support, built-in plug and play, and more.

In December 2003, the Linux 2.6 kernel was released, and there were major changes in support for the system compared to the 2.4 kernel.

In January 2004, SuSE married Novell, SCO continued to force its way around in the face of infamy, and Asianux and MandrakeSoft reported their first quarterly profits in five years. In March, SGI announced the successful implementation of Linux operating system support for 256 Itanium 2 processors.
