I have a simple script as below which checks if fail2ban service is running or not on Ubuntu 18.04:

#!/bin/bash

# Script to check if fail2ban service is running

if pgrep -x "fail2ban" > /dev/null
then
   echo "Fail2ban is running"
else
   echo "Fail2ban is not running"
fi

I have installed fail2ban in a test VM and is running on the VM. Here is a screenshot of systemctl status command.

But, when the run the above script, I get the result that "Fail2ban is not running". I am not sure if is with the script. I tried ps aux command too instead of pgrep. But, I still get the same result.

bash process administrator
