Would you not expect to execute something between the last do and done for the while loop?

If the output from a single query using tablespace TSADOR is:-
Code:
$ db2 "list tablespaces show detail" |grep -p -w TSADOR |egrep "Name|Total pages|Free pages|Page size" 
Name                       = TSADOR
 Total pages               = 14991360
 Free pages                = 5345152
 Page size (bytes)         = 32768
$

...then I'm wondering why the awk is here.

Could you try:-
Code:
$ db2 "list tablespaces show detail" |grep -p -w TSADOR | egrep "Name|Total pages|Free pages|Page size" | while read label equals value rest
do
   echo "$label\t\c"       # Display third item then tab but don't end the output line.
done ; echo                # End the output line

... and see if that gives you the output you need for one tablespace.

If so, then you can blend that back to what you already have to loop round for each tablespace. If not, show us the output and we'll see if we can fix it. I might be good to see the plain output from:-
Code:
$ db2 "list tablespaces show detail"

by itself so we can consider if this is the best approach. It might be possible to write the query to format the output instead. If it was Oracle, I'd do something like:-
Code:
$ cat my_query.sql
column tablespace_name format a15 ;
column total_pages format 99999 ;
column free_pages format 99999 ;
column page_size format 99999 ;
select tablespace_name 'Tablespace name', total_pages 'Total Pages', free_pages 'Free Pages', page_size 'Page Size' from dba_tablespaces
where tablespace_name in
( select unique tablespace_name from dba_segments where owner = 'SCHEMA' and segment_name like '%XXXX%' ) ;

$ sqlplus / @my_query.sql

I can't remember the exact syntax and don't have a server to try this on, but obviously there will be variations to drive against DB2.


Do these help?

create_tablespace

CREATE 
TABLESPACE(7)						   SQL Commands 					      CREATE TABLESPACE(7)

NAME

       CREATE TABLESPACE - define a new tablespace

SYNOPSIS

       CREATE TABLESPACE tablespacename [ OWNER username ] 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 tablespacename to CREATE DATABASE, CREATE TABLE, CREATE INDEX or ADD CONSTRAINT to have the
       data files for these objects stored within the specified tablespace.

PARAMETERS

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

       username
	      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 must 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.
