Extract all tablespaces DDL

Nice and easiest way to to extract the DDL for all tablepaces..

 Generate the DDL using the below query and you can re create the table spaces in any environment with any changes you want to make.

set heading off;
set echo off;
Set pages 999;
set long 90000;
spool ddl_list.sql

select dbms_metadata.get_ddl('TABLESPACE',tb.tablespace_name) from dba_tablespaces tb;

spool off

(sample) output will look something like this:

"
  CREATE TABLESPACE "SYSTEM" DATAFILE
  '/u02/oracle/oradata/system01.dbf' SIZE 314572800
