Quick overview of UNIX → GNU → Linux history
What is Linux?
Linux is an open-source operating system kernel. It acts as the core part of many OS distributions like Ubuntu, Fedora, and Arch. Though based on UNIX principles, Linux is not a direct UNIX clone — it was written from scratch and is completely free to use and modify.
Before Linux
Before linux unix-created in 1969 at bell Laps by Ken Thompson and Dennis Ritchie. It was - Multi tasking.multiuser,commandline.....
But the problem is,
It was paid if you can use but you cannot change or modify because it is not open source.
so The superHero(Richard StallMan) Entered,
started the GNU Project (1983) to build a free UNIX-like OS. He made lots of tools like compilers, shell,Terminal ,editors — everything but the kernel.
!!!Everything was ready except the heart of the system — the kernel!!!
Who invented the Linux kernel?
In 1991, a 21-year-old Finnish computer science student named Linus Torvalds was frustrated with MINIX (a small UNIX-like system for students). It was limited, and he wanted something better
So, he began writing his own kernel as a personal hobby using his Intel 386 PC.
In August 1991, he posted a message on a newsgroup:
! I’m doing a free operating system — just a hobby, won’t be anything big.!
That hobby changed the tech world forever.
Where he published?
Linux was released under the GNU General Public License (GPL), which allowed anyone to use, study, and modify the code.This community-driven model led to rapid improvements and wide adoption. Thousands of developers worldwide contribute to Linux today.
** Linux in Servers and Supercomputers**
Linux soon became a favorite for web servers, databases, and high-performance computing because of its:
Stability,
Security,
Cost-efficiency.
Today, over 90% of supercomputers and most internet servers run Linux.
Linux is only for computers
Nope!.....Linux is not just for computers — it's everywhere!. Android, the world’s most used mobile OS, is built on Linux.It's used in smart TVs, routers, cars, robots, and IoT devices.
** Modern Linux: Cloud, AI, Dev-Ops**
Linux is the backbone of modern technology:
Cloud platforms (AWS, Azure, GCP),
DevOps tools (Docker, Kubernetes),
AI and machine learning frameworks.
It’s also supported by organizations like the Linux Foundation, which guides large-scale development.
** Linus Torvalds Today**
Linus Torvalds, the creator of Linux, is still actively involved in maintaining the kernel. He oversees code submissions and leads development, ensuring Linux stays stable and secure.
Guys If anyone think why this name came for Linux let explore
When Linus Torvalds wanted to name it “Freax” — a mix of the words “Free”, “Freak”, and “UNIX.”But when he uploaded the code to a public FTP server at Helsinki University, the server administrator Ari Lemmke didn’t like the name Freax. So, without asking Linus, he renamed the folder to:
Linux = Linus + UNIX
Few some ENDING words for Linux
From a college student’s hobby to the engine behind global tech, Linux has proven that open collaboration and free software can change the world.Whether you're using a phone, browsing the internet, or running cloud servers — you're likely powered by Linux.The combined vision of Richard Stallman's free software philosophy and Linus Torvalds' practical kernel built the foundation for today's digital age.
Linux is not just software — it’s a movement.
