Problem description:
I'm currently working on the shell script in order to stop the listener. I tested the script and it gave me an error below. If anyone knows what I did wrong, please reply. I really appreciate it.

"NL-00857: wrong number (0 - 1 needed) of arguments to "password""

This is my script:

su - oracle -c "opt/app/oracle/product/7.3.4/bin/lsnrctl set password apple1 stop"
