Finding documentation for the /proc/sys/vm using a shell - Chap 13 - Memory Monitoring and Usage
Can someone please help me understand where to find this information using the shell? Thanks!
From Chap 13 - Memory Monitoring and Usage - /proc/sys/vm: "You can find the full documentation for the /proc/sys/vm directory in the kernel source (or kernel documentation package on your distribution), usually under Documentation/sysctl/vm.txt."
info on my system:
me@me:/etc
$ cat mx-version
MX-19.2_KDE_x64 patito feo August 16, 2020
me@me::/etc
$ uname -r
5.6.0-2-amd64
Thank you, in advance!

I don't recognize your distribution so I can't give you specifics as to the packaged documentation (The names smells like Mint Linux which I no longer bother to keep up with as I advise people to stick with Ubuntu or Debian for various reasons I won't mention) -- there is always a "kernel-docs" or some such package. Or if you have the kernel sources, you can easily look in the "Documentation" directory.
Even easier: kernel.org/doc/Documentation

hi coop. I was having the same issue as punko here, on Ubuntu 20.04, while following the course material. Several areas of the course referred to the kernel doccos, but by all means, I could not find the stuff on any of my systems, be them vms, or physical.
Below, are two different systems, running two different kernels.
broken is a fresh install, deployed roughly a month ago, while squids has been my ubuntu desktop for about 3 years.
None have the documentation installed and present, however after installing linux-doc on both, I can find the documentation in /usr/share/doc/linux-doc.
This appears to be an optional package, on ubuntu, at least, yet I was never able to find the documentation present on fresh installations of fedora 33, openSuse Leap, Centos7 or Centos8.I recommend not addressing this, as it allows candidates to search for a solution on their own and check the man pages, as I did.

andrei@squids:~$I hope this helps.

these days i have been pointing to the online kernel.org documentation as it is formatted better.
