TOADDR=someone@example.com
REPORT=`mktemp`
TODAY=`date +%F`

sqlplus -S / as sysdba <<EOF > $REPORT
set linesize 200
set pagesize 500
column "EXPIRE DATE" format a20
select
        username as "USER NAME",
        expiry_date as "EXPIRE DATE",
        account_status
from
        dba_users
-- where
--      expiry_date < sysdate+120
--      and account_status IN ( "OPEN", "EXPIRED(GRACE)" )
order by
        account_status, expiry_date, username
/
EOF
mail -s "Oracle Password Status: $TODAY" $TOADDR < $REPORT
rm $REPORT

Does it work for anyone?
