Why du -sh * tells me sys has 0 size?

Question

I use du -sh * to find out the size of folders, but the sys folder is giving me 0, and the same about any folder inside sys. find . | wc -l gives me 11k files. Do you know why and can you suggest a workaround?

thanks

Answer 1

What do you want to work around? 0 is the correct number. /sys is a virtual filesystem, consisting of kernel data exposed in a filesystem-like interface. It does not actually take up any space.
