Amazing. I've been 'staring' at the sys rq key for 20 years with Linux and many years before with Win/Dos, and never really knew how it worked, for what, or if it was still used for anything - even then.
Apparently (from light search) sysreq was mostly used in the old days to halt current job and enter a systems menu.
Anyway, thanks for fixing a long-standing knowledge gap :-)
I'm glad you appreciate it! It's always fun digging into kernel internals and learning new things :D
I'm also open to criticism about the writing if you have any.
No one knows what SysRq was meant for.
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.
