How it works
A symbolic expression is a comma-separated list of clauses of the form [who][op][perm]. who is u, g, o, or a (empty means a); op is +, -, or =; perm is any of r w x X s t, or a copy of another class's bits using u, g, or o. This tool applies each clause in order and shows the mode before and after. It does not model umask, which real chmod only applies to a bare + when no explicit permission is given.
