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.

Is it just me, or are the definitions for /sys and /proc mixed up?

[–] [email protected] 3 points 2 months ago

Nah, it's just that /proc is incorrect - it contains information about running processes, as well as kernel data structures as visible by the process reading them.

No I thinks is basically right although could be better worded maybe

/sys is virtual file structure for kernel system info

/proc is virtual file structure of kernel process info

My understanding is /proc came first but was abused/free for all and started being used for all sorts of non standard/process kernel access. So /sys was created with stricter rules to make it more standardised.
