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?
