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.

Hey, I've recently designed a Poster about the FHS since I often forget where I should place or find things. Do you have any feedback how to make it better?
I updated the poster: https://whimsical.com/fhs-L6iL5t8kBtCFzAQywZyP4X use the link to see online.

Super useful, thanks. Actually made a lot of things click in my head about how Linux works.
When did /home get deprecated? Is /usr/local the replacement?
Sorry for the n00b question (I'm not a noob, but I have been off Linux for a few years), figured the answer may be useful to other users too
/home is not deprecated, it's optional but common. Here is the section from FHS: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s08.html
then the legend should be fixed its confusing, as is the whole idea of FHS is outdated and a chore for new users to get into (i still don't fully understand it)
The legend is a bit broken. Will fix it maybe.
As for the rest, yes, the FHS can be confusing. It's from a time where mostly professional admins would deal with it and requirements were pretty different from today's end-user systems. If you want to understand more, I urge you to read the spec. It's highly readable! https://refspecs.linuxfoundation.org/FHS_3.0/fhs.html
/mnt is for more permanent stuff. /run is for shit like a USB drive some user has connected. It's the place that most distro automount your attached storage by default (/run/$USER/$DEVICE/)
