Hi colleagues, thank you for you fast response,
I have run this commands

Code:
db2 -x "select substr(TBSPACE,1,20) TABLESPACE from syscat.tables where tabschema = 'MIATLAS' and tabname like '%TH' group by TBSPACE order by 1" | while read tablespace
do 
  db2 "list tablespaces show detail" |grep -p -w $tablespace | egrep "Name|Total pages|Free pages|Page size" | while read label equals value rest
   do
     echo "$label $equals $value $rest\t\c" 
done ; echo
done ; echo

the output is as follows

Code:
Name = TSADOR   Total pages = 14991360  Free pages = 5345152    Page size (bytes) = 32768
Name = TSHISTNEW        Total pages = 4186112   Free pages = 1276544    Page size (bytes) = 32768
Name = TSHISTTI         Total pages = 6279168   Free pages = 1991168    Page size (bytes) = 32768

I need to do a multiplication for the output to be like this.

Code:
Name = TSADOR           Total pages = 14991360  Free pages = 5345152    Page size (bytes) = 32768   Mb=Free pages*Page size (bytes)
Name = TSHISTNEW        Total pages = 4186112   Free pages = 1276544    Page size (bytes) = 32768   Mb=Free pages*Page size (bytes)
Name = TSHISTTI         Total pages = 6279168   Free pages = 1991168    Page size (bytes) = 32768   Mb=Free pages*Page size (bytes)

thanks for your valuable help.

MINCORE(2)						      BSD System Calls Manual							MINCORE(2)

NAME
mincore -- determine residency of memory pages SYNOPSIS
#include <sys/types.h> #include <sys/mman.h> int mincore(caddr_t addr, size_t len, char *vec); DESCRIPTION
The mincore() system call allows a process to obtain information about whether pages are core resident. The current core residency of the pages is returned in the character array vec. For each entry in the character array vec, the following bit values may be set depending upon the state of the page: MINCORE_INCORE 0x1 /* Page is incore */ MINCORE_REFERENCED 0x2 /* Page has been referenced by us */ MINCORE_MODIFIED 0x4 /* Page has been modified by us */ MINCORE_REFERENCED_OTHER 0x8 /* Page has been referenced */ MINCORE_MODIFIED_OTHER 0x10 /* Page has been modified */ RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS
[EINVAL] addr is not a valid address for user mode. [EFAULT] an error occurred trying to copy to the output character array vec. SEE ALSO
madvise(2), minherit(2), mlock(2), mprotect(2), msync(2), munmap(2) HISTORY
The mincore() function first appeared in 4.4BSD. BSD
June 9, 1993 BSD
