I'm trying to obtain a recursive directory listing of my filesystem using the command

$ ls -alRc 

from root directory.

Everything is running fine except the /proc directory listing, which results in the following errors:

How to deal with this?

Thanks in advance.

You don't "deal with" this, it's normal.

/proc is a virtual filesystem, as are /dev and /sys (if present), meant to present system information and provide a file-like way to change the system configuration - that is, those files aren't really on your hard disk.

http://linux.die.net/man/5/proc

All sorts of broken links and loops and I/O errors can and will occur if you try to iterate over /proc it as if it were a "regular" folder, because... it's not.

So, the answer is: you don't.

If you want, you can silence the errors by redirecting them to /dev/null:

$ ls -alRc 2> /dev/null

For the sake of experimentation, notice how doing a cat /dev/null afterwards does not print your errors - because as we said /dev is a virtual filesystem and /dev/null is not a real file but... the closest analogue to a black hole you'll find in a Linux system :)
