trying to get plugin to run a bash script

[RudyRipDraw]

I would like the countdown plugin to run a bash script at the end. I added these to lines to countdown.py source code but it is not working.
Can anybody help me figure out how to get my shell script "doit.sh" to run within InkyPI countdown plugin?

thanks

from plugins.base_plugin.base_plugin import BasePlugin
from PIL import Image
from datetime import datetime, timezone
import logging
import pytz
import subprocess

::

image = self.render_image(dimensions, "countdown.html", "countdown.css", template_params)

subprocess.run(["/bin/bash", "/home/rudy/doit.sh",shell=True])

return image
