    man find:

       -perm mode
              File's permission bits are exactly  mode  (octal  or  symbolic).
              Symbolic modes use mode 0 as a point of departure.

       -perm -mode
              All of the permission bits mode are set for the file.

       -perm +mode
              Any of the permission bits mode are set for the file.
