Unix is 40 years old today. It didn’t seem that long ago, but then again it seems like Unix has been around for a very long time. Now, take a look at this OS timeline here and you will see missed opportunities for Unix to get a foothold on the desktop computing in the early 1980’s. It’s too bad Unix could not take advantage of its opportunities before IBM and eventually Microsoft came along with their PC-DOS and Windows operating systems. Linux was born in 1991 when Finnish Linus Torvalds released an Unix-like kernel which subsequently turned into dozens of Linux distributions that we see today. Fast forward to now and the future, you see a world deeply entreched on the Windows. It’s still an uphill battle to get people to recognize that there is a third option to Windows and Apple operating systems. Unix and Linux in general have come a long way from its humble command-line beginnings to the current Gnome based GUIs.
