trap is part of bash.

I would be *very* surprised if you don't have it.

I used exactly what you posted with "#!/bin/bash" at the top and "sleep 10000" at the bottom, and it worked.

So something else that you are doing is stopping it.

hey, Perderabo

please find the o/p of
command -V trap as trap is a shell builtin
and echo $BASH_VERSION as 3.00.15(1)-release

set pagesize 0 feedback off verify off heading off echo off serveroutput on size 10000
whenever sqlerror exit 1
$var12
commit;
exit ;
ENDSQL`
var12=""
}

function trap_cmd {
echo "It's wrong way to stop the process."
exit 2
}

echo " Runnnig process id is : $$"
select_outbox="SELECT outbox_retn FROM CBF_CONFIG WHERE CS_ID='"$1"';"

get_connection "$select_outbox"

echo $v_cnt

sleep 600

trap 'trap_cmd' 1 2 3 4 5 6 7 8 9 10 12 13 14 15 20
