Is there a way to start/stop multiple listeners with one command

Hi All,

If we have multiple listener like

LISTENER1

LISTENER2

LISTENER3

...

LISTENERn

Is there a way to start/stop all of them in one command? I am trying to avoid using the script like:

#!/bin/bash

for i in {1..2};

do

lsnrctl stop LISTENER$i

done;

Thank you,
