So I execute the find command in the picture, why there are so many permission denied? I am a root user. Just this problem.

  • You're copying everything owned by root on the whole system down into /root/results, including the contents of /root/results? Why? Also /proc is not a directory of ordinary files. – Kusalananda Dec 28 '18 at 7:46
  • /proc exists only in memory and is virtual so you can't copy it! The error is normal! – George Udosen Dec 28 '18 at 7:54

The /proc and also the /sys exists only in memory and is virtual so you can't copy it!

These are pseudo−filesystems because they exist totally in memory; if you look at the disk partition when the system is not running, there will be only an empty directory which is used as a mount point.

So the error is absolutely normal!

  • Can those directories be copied as OP is trying to? – George Udosen Dec 29 '18 at 10:29
