The question is in the title. What does the number 0 signify?

    Where are you seeing it? What it means depends on exactly where you see it.

  • In the output of what command are you seeing it? Or as the argument to which? E.g., my ls -l prints permissions symbolically, and doesn't print 0. But its also not really a "list", so I'm at a loss as to where you're seeing this.

That it belongs to user/group with ID 0. That would be root (see /etc/passwd and /etc/group).

    Note that on some systems (most notably the *BSDs) the group with the numerical id 0 is called wheel, not root.

0=no rights for owner/group (quite unusual).
