LINUX Understanding inodes

773 ratings | 60395 views
More videos like this online at http://www.theurbanpenguin.com Here we take a tour to make sure that we do truly understand inodes in Linux and what they do and contain. Firstly they do not contain the file name. This is stored separately and the file name is linked via the inode number to the inode. The inode itself contains the metadata about the file: the mode, ownership, size etc. Keeping the filename separate to the file metadata does mean that we can have then hard links, multiple file names that point to the one file by way of the inode. We will take a look at the ls command with the -i option along with stat and find -inum ; all of these command line tools help you gain knowledge and use inodes effectively in your system

What is the point of having an automated hand slowly "writing out" text?
PENDANTturnips (9 months ago)
Orkish I guess the main reason is that it makes the video more engaging, resembling a university lecture or a higher budget video with animations. This can engage more of your brain since most people like to see stuff moving, I think we're more evolved to absorb information like this than talking over still images. Other benefits are that information is more gradually displayed to you, giving you time to process what each part represents. I personally like it, more interesting than the other OS lectures out there from uni profs who talk over still PowerPoints.
