From the comments in the script:
“Created this script after I had several misconfigurations across many servers – this will
use values from the config files for testing – a wrapper for fail2ban-regex and eliminating
late-night, low-on-caffeine human errors in testing your config. Could also be used: after an
update to verify the configuration, run weekly cron, create a fail2ban report..”
