FAQ
What is the difference between 3-digit and 4-digit numeric?
3-digit (e.g. 755) is basic permissions (owner/group/other). 4-digit (e.g. 4755) adds setuid/setgid/sticky bits as the leading digit.
What is setuid?
setuid (Set User ID) is a special bit that causes a file to execute with the owner's permissions. It is set with a leading 4 (e.g. 4755).
