sqlplus -silent rep/qpalwo@cbi <<END
set pagesize 0 feedback off verify off heading off echo off serverout on size 100000
DECLARE
date1 DATE:=NULL;
date2 DATE:=NULL;
BEGIN
DBMS_OUTPUT.enable(100000);
select hdsg.HLD_DI_SRC_GRP_DATE into date_1 from di_hold.HOLD_DI_SRC_GRP hdsg where hdsg.HLD_DI_SRC_GRP_NAME = $1;

select hdsg.HLD_DI_SRC_GRP_DATE into date_2 from di_hold.HOLD_DI_SRC_GRP hdsg where hdsg.HLD_DI_SRC_GRP_NAME = $2;

select trunc(sysdate) into current_date from dual;
IF current_date = date_1 and current_date = date_2
THEN
DBMS_OUTPUT.put_line('1');

Replied in your other posting:

You can invoke the "abc.sh" from your other shell script like:
abc.sh arg1 arg2

In you abc.sh, make your function use these arguments as $1,$2 ... and return 1 or 0.

OK - Here's some problems for you to overcome.

Your Oracle looks like it is using character strings for your variables. Which means that must be surrounded by quotes.

If you use quotes in your variables when you call, UNIX will strip them out.

This will get you into some interesting OS/bash dependencies I cannot help you with, but you need to consider.

try abc.sh "\'arg1\'" "\'arg2\'" to pass the single quotes to the arguments as Oracle is expecting.
