Using the SQL one can create a list of tables to pass as a parameter to export (exp).

set heading off
set pages 0

— create the list for a specific user
SELECT DECODE( rownum, 1, ‘tables=(‘, ‘,’ ), owner || ‘.’ || table_name FROM dba_tables WHERE owner IN ( ‘SCOTT’ )
UNION ALL
SELECT ‘)’, null FROM dual;

Output:
tables=( SCOTT.USERS
, SCOTT.DEPT
, SCOTT.EMP
, SCOTT.BONUS
, SCOTT.SALGRADE
, SCOTT.TEST_OBJECTS
, SCOTT.STATS_BACKUP
, SCOTT.DUMMY1
, SCOTT.BIGEMP
, SCOTT.MYDUAL
)

— in the example below it will create list of tables that begin with F but using the example you can create
SELECT DECODE( rownum, 1, ‘tables=(‘, ‘,’ ), owner || ‘.’ || table_name FROM dba_tables WHERE table_name like ‘F%’
UNION ALL
select ‘)’, null from dual
