Linux in !980s

Linux in 1980s

In the Eighties many companies started developing their own Unix: IBM created AIX, Sun SunOS, HP HP-UX and about a dozen other companies did the same. The result was a mess of Unix dialects and a dozen different ways to do the same thing. And here is the first real root of Linux, when Richard Stallman aimed to end this era of Unix Separation and everybody reinventing the wheel by starting the GNU project.  His goal was to make an operating system that was freely available to everyone, and where everyone could work together. Many of the command line tools that you use today on Linux are GNU tools.
