 Check for granted privileges on directory objects

SET lines 110
COL privilege FOR a12
COL grantee FOR a25
COL owner FOR a25
SELECT p.grantee, p.privilege, p.owner, d.directory_name 
  FROM dba_tab_privs p, dba_directories d 
 WHERE p.table_name=d.directory_name 
   AND (grantee IN ('TEST', 'PUBLIC') 
        OR grantee IN (SELECT granted_role FROM dba_role_privs 
                        WHERE grantee IN ('TEST', 'PUBLIC'))) 
 ORDER BY 4,3,2; 

A typical output is 
GRANTEE              PRIVILEGE  OWNER                DIRECTORY_NAME

EXP_FULL_DATABASE    READ       SYS                  DATA_PUMP_DIR
