How to get all the inodes under the linux filesystem with python?

I'm trying to do some calculations on inodes (Get their size, etc...) All I found in the web was how to get the inode of a certain file or directory, but I want to get all the inodes with a single call, and then use them one by one have any ideas ?

Thanks

Solution

How about this?

import os
inodes = os.popen("sudo ls -Rli / | awk '{ print $1 }'").read().split('\n')
inodes = [int(i) for i in inodes if i.isnumeric()]

For my home folder, this returns a list of the inode numbers:

[11666512, 10223622, 10234894, 10223641, 10223637, 10617011, 10254828, 10249545, 10223642, 10223643, 10487015, 10223640, 11929556, 10223639, 10223644, 10486989]

To clarify, the ls command takes three flag arguments, R, l and i. R performs a recursive search to check all files in the folders and all subfolders starting with /, l formats the output to give us a list, and i gives us the inodes. We pass the results to awk to get the first column which contains the inodes and then do some simple cleaning of that data.
