Could you please let me know how to call a shell script from PLSQL program?

You have a couple of options available:
- Invoke a Java method from within a PL/SQL wrapper.
- Call a C program as an external procedure from within PL/SQL.
- Use the new DBMS_SCHEDULER package.
Here's a link with INFO on them.

In the second solution, is there any other direct way.

@ChandraBhushan - what do you mean by "there any other direct way"?
And a forth way (on top of Pablo's) dbms_pipe
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:16212348050
In Oracle7.0 and up, we can use dbms_pipes to talk to a daemon running outside the database. Here is a simple example that uses sqlplus to be the daemon:
create or replace procedure host( cmd in varchar2 )
as
status number;
begin
dbms_pipe.pack_message( cmd );
status := dbms_pipe.send_message( 'HOST_PIPE' );
if ( status <> 0 ) then raise_application_error( -20001, 'Pipe error' );
end if;
end;

Not listed above, but still applicable: C Code direct library from PL/SQL from Ask Tom. Obviously it would be an execution of a C Wrapper to call out to the Shell script.

Tom's example is actually just another sample of method #2 i.e. an external procedure.
