simple_subprocess_demo.py

import subprocess
from time import sleep

print("Program started...")
count = 0
while count < 3:
    sleep(5)
    print("Calling subprocess...")
    completed_process = subprocess.run("./check_users.sh", shell=True)
    # You can then call attribute or methods of completedProcess here
    completed_process_returncode = completed_process.returncode
    print(
        f"Returncode of round {count+1} of executing the process is: {completed_process_returncode}..."
    )
    count += 1

print("All done!")
