Here is a adoption for running the ls command ... be very careful with suspriv command, it is very powerful privilege. One could replace ls with rm and then you are doomed if oracle is running as root.

grant javasyspriv to system
/

create or replace type fileList as table of varchar2(255)
/

create or replace and compile java source named "DirList" as
import java.io.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.*;
public class DirList
{
public static ARRAY getList(String directory)

                             throws SQLException

{

    File path = new File( directory );
    Connection conn =

          new OracleDriver().defaultConnection();     ArrayDescriptor descriptor =
      ArrayDescriptor.createDescriptor( "FILELIST", conn );     return new ARRAY( descriptor, conn, path.list() ); }
}
/

create or replace function get_dir_list( p_directory in varchar2 )   return fileList
as language java
name 'DirList.getList( java.lang.String )

      return oracle.sql.ARRAY.ARRAY';
/

set serveroutput on
declare

    l_files fileList;
begin

    dbms_output.enable(1000000);
    l_files := get_dir_list( '/home/oraclei/code' );

    for i in 1 .. l_files.count
    loop

        dbms_output.put_line( l_files(i) );     end loop;
end;
/

yeah, I'm trying to get away from C external procedures ...but java is beginning to look just as much a hassle.

Why is running a OS command such hassle?
