Is there a pictorial representation of Linux filesystem, to understand the Linux filesystem. Currently running Ubuntu 16.04 and I want to efficiently re-install, using 2 HDD, 1x250GB and 1x500GB. The 250GB being the faster drive.


Currently FileSystem Hierarchy Standard (FHS) is in version 2.3. To get an in-depth knowledge about it, Visit this page on Linux Foundation.

Also as answered by dr01, you can have a crisp knowledge about it at Wikipedia : FileSystem Hierarchy Standard.

Would like to add this beautiful image from this Source. I reference this image every now and then. But please note that none of the directories should be capitalized.

    @Rich Not only SHOUTING and misleading, it's actually incorrect, as /USR isn't the same as /usr. And /usr is correct... – Andrew Henle Mar 29 '18 at 13:32
  • I just noticed it's also missing /lost+found, /net, /proc and /sys. There's an update at that URL that includes /proc, /media, and /srv, but it's still ALLCAPS, and it's still missing /lost+found, /net, and /sys. – Rich Apr 5 '18 at 18:20
  • @AndrewHenle - I gave the author a prod on his blog there :-) I'd really like to print this out. – Rich Apr 5 '18 at 18:29

The Filesystem Hierarchy Standard (FHS), maintained by the Linux Foundation, defines the filesystem hierarchy and directory structure and contents in all Linux distributions.

It is described here: Filesystem Hierarchy Standard | Wikipedia


This might be of some help.It gives a basic overview of the how directories and files exist in linux File System
