How to call shell script from Toad - oracle

Question

I tried with the below linked steps:
https://slobaray.com/tag/execute-shell-script-from-plsql/
It consists in
creating a java object stored as BASH_OS function with
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "BASH_OS"..
Then to execute the java with
CREATE OR REPLACE PROCEDURE unix_command (p_command IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'BASH_OS.executeCommand (java.lang.String)';
But It shows that
the object BASH_OS does not exist.
Can any one help me on how we can execute the shell script from the Toad with this method?
or Is there any other method to call shell script from Toad?

Answer 1

Referring your link, I found that the class name in line 13 is wrong for creating BASH_OS.
The class name should be "BASH_OS" instead of "Host". Since there is no comment feature on the blog, so i copy the fixed code here.
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "BASH_OS" AS
/******************************************************************************
NAME: BASH_OS
PURPOSE: To perform the shell command using Java class
