From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Not Linux but there are still a of Unix System V systems out there too. AIX, Solaris and HP-UX. Harder to learn as very much not open source software (although there is the Illumos project with distros like OpenIndiana).
Wow, last time I managed HP-UX, SunOS/Solaris, AIX, and Irix, was last century...
Unfortunately AIX in particular is very much still in use in my industry. Its slowly being phased out but is very much still there.
Impressive :) starting in the 2000s I was maintaining a park of SCO servers (yes, the infamous SCO) but starting 2010ish it was all Linux...
In banking I suppose? Or airline? Having hard time seeing AS400 in Banking.... at least some are using IBM Z nowdays...
Healthcare. People keep systems for decades.
I see. I seen some still using palmOS. Is there still any palmOS in production?
