It is just standard output, not db2 magic! I often put a marker on my data for security. Something like this works with every DB command line tool.
Code:
echo 'select dAtA x, whatever from wherever ;'|db2 . . . |sed '
  s/.*dAtA //
  t
  w /logdir/logname
  d
 '|while read ....
  do
    ....
  done

You may try this.

Code:
#!/bin/ksh
db_name=db
db_user=usr
db_pwd=pwd

db2 "connect to $db_name user $db_user using $db_pwd"
db2 "select count(1)  from table" > $HOME/count.dat
db2 "connect reset"

Hi Sup,

You can redirect the entire dblog event to the log file as below and then you can do the filtering on the same.

Code:
db2  <<EOSQL>/home/testuser/count.lst

Thanks & Regards,
