The e executive director for the Free Software Foundation is William John Sullivan, which in turn supported the GNU components. The lead maintainer of the Linux Kernel is Greg Kroah-Hartman who guides its development. Developers operated to develop GNU elements with the Linux Kernel, making a free and fully functional operating system. Torvalds started a switch from his actual license, which banned commercial distribution, to the GNU GPL.

Also, GNU applications replaced every MINIX component due to it was beneficial to use the free code through the GNU Project with the new OS code licensed upon the GNU GPL can be re-applied in other computer functions as long as they are also published under a compatible or the same license.
Later, Linux was cultivated, and then the development of the Linux kernel appeared on Linux systems. Torvalds started the Linux kernel development on MINIX, and software written for MINIX was used on Linux as well. Frustrated by the MINIX licensing, which limited it to only educational use at the time, he started to work on his operating system kernel, which became the Linux Kernel eventually. He became interested in operating systems in 1991. It was together with this course that Torvalds initially became open to Unix. The textbook contained a copy of the MINIX operating system of Tanenbaum. The course used a MicroVAX minicomputer executing Ultrix, and one of the needed texts was Operating Systems: Design and Implementation by Andrews S. Torvalds registered in a Unix course while visiting the University of Helsinki in the 1990's fall. The availability of a Unix high-level language implementation made its porting to distinct computer platforms convenient. It was updated in the C language by Dennis Ritchie in a key pioneering way in 1973. First published in 1971, Unix was entirely written in assembly language, as was the basic practice at the time. The Unix-based operating system was implemented and conceived in 1969 at AT&T's Bell labs by Joe Ossanna, Douglas Mcllroy, Dennis Ritchie, and Ken Thompson in the United States. For example, the Linux kernel is licensed upon the GPLv2. The source code may be distributed, modified, and used non-commercially or commercially by everyone under the conditions of its respective licenses, like the GNU GPL (General Public License). Linux is one of the most outstanding examples of open-source and free software collaboration. It includes spacecraft (Perseverance rover, Dragon crew capsule, and Falcon 9 rocket), automobiles (Toyota, Hyundai, Mercedes-Benz, Audi, and Tesla), televisions (LG and Samsung Smart TVs), video game consoles, smart home devices, automation controls, and routers.Also, Linux executes on many embedded systems, i.e., devices whose OS is typically designed into the firmware and is extremely customized to the system.However, Linux is used by just around 2.6% of desktop computers as of November 2022.

Commercial distributions are SUSE Linux Enterprise and Red Hat Enterprise Linux. Several Linux distributions use the term "Linux" in the title, but the Free Software Foundation uses the "GNU/Linux" title to focus on the necessity of GNU software, causing a few controversies.įamous Linux distributions are Ubuntu, Fedora Linux, and Debian, the latter of which is composed of several different modifications and distributions, including Xubuntu and Lubuntu. Typically, Linux is packaged as the Linux distribution, which contains the supporting libraries and system software and kernel, several of which are offered by the GNU Project. Linux is an open-source Unix-like operating system-based family on the Linux kernel, and the OS kernel was first published on 17 September 1991 by Linus Torvalds.
