unix variables from sql / pl/sql
How do I dynamically assign the below output to unix shell variables
so I can build a menu in a shell script?

Example:

var1 = 1 var2= SYSTEM
var3 = 2 var4= UNDOTBS1

and so on, then in the shell script I can use the variables to build a menu.




set serveroutput on

declare
v_counter number(2):=0;
v_tbs dba_tablespaces.tablespace_name%type;

cursor tbs_cur is
select tablespace_name
from dba_tablespaces
where tablespace_name not in ('TEMP');

begin
open tbs_cur;
dbms_output.put_line('Number'||' '||'Tablespace Name');
loop
exit when tbs_cur%notfound;
fetch tbs_cur into v_tbs;
v_counter := v_counter+1;
exit when tbs_cur%notfound ;
dbms_output.put_line(v_counter||' '||v_tbs);
end loop;
close tbs_cur;
end;

create_tablespace

CREATE 
TABLESPACE(7)					  PostgreSQL 9.2.7 Documentation				      CREATE TABLESPACE(7)

NAME

       CREATE_TABLESPACE - define a new tablespace

SYNOPSIS

       CREATE TABLESPACE tablespace_name [ OWNER user_name ] LOCATION 'directory'

DESCRIPTION

       CREATE TABLESPACE registers a new cluster-wide tablespace. The tablespace name must be distinct from the name of any existing tablespace in
       the database cluster.

       A tablespace allows superusers to define an alternative location on the file system where the data files containing database objects (such
       as tables and indexes) can reside.

       A user with appropriate privileges can pass tablespace_name to CREATE DATABASE, CREATE TABLE, CREATE INDEX or ADD CONSTRAINT to have the
       data files for these objects stored within the specified tablespace.

PARAMETERS

       tablespace_name
	   The name of a tablespace to be created. The name cannot begin with pg_, as such names are reserved for system tablespaces.

       user_name
	   The name of the user who will own the tablespace. If omitted, defaults to the user executing the command. Only superusers can create
	   tablespaces, but they can assign ownership of tablespaces to non-superusers.

       directory
	   The directory that will be used for the tablespace. The directory should be empty and must be owned by the PostgreSQL system user. The
	   directory must be specified by an absolute path name.

NOTES

       Tablespaces are only supported on systems that support symbolic links.

       CREATE TABLESPACE cannot be executed inside a transaction block.

EXAMPLES

       Create a tablespace dbspace at /data/dbs:

	   CREATE TABLESPACE dbspace LOCATION '/data/dbs';

       Create a tablespace indexspace at /data/indexes owned by user genevieve:

	   CREATE TABLESPACE indexspace OWNER genevieve LOCATION '/data/indexes';

COMPATIBILITY

       CREATE TABLESPACE is a PostgreSQL extension.

SEE ALSO

       CREATE DATABASE (CREATE_DATABASE(7)), CREATE TABLE (CREATE_TABLE(7)), CREATE INDEX (CREATE_INDEX(7)), DROP TABLESPACE (DROP_TABLESPACE(7)),
