given that it's not linuxmint specific, check wikipedia for a generic understanding of these 2 filesystems.

If you want to know more, you will need to study the the linux/gnu operating system in its entirety. /proc and /sys make sense only if you know how the os works.

I'm not sure I understand what you are saying, however please note that the files in these 2 filesystems are not real files. In Linux everything is represented like a file but not everything is a file understood as 'data saved in memory'. /proc and /sys are virtual filesystem, created/mounted at boot to help other processes (like dbus, hald, etc..) functioning correctly.

My suggestion for you is: load your distro, browse inside /proc and /sys and check what's inside. For example, check the content of /proc/cpuinfo or /proc/interrupts...

Code: Select all

# get cpu information
cat /proc/cpuinfo
# get IRQs information
cat /proc/interrupts
# list content of sys
ls -l /sys
