Check if snort is running

[battles]

I have found that snort wasn't running on several occasion, seemingly because of some kind of rules download error.  The last time was in this message:
https://forum.pfsense.org/index.php?topic=117233.0

It was rather aggravating to always be in the dark as to whether snort intrusion protection was running.  I have written a quick bash script that checks every minute to see if snort is running and puts out 6 alternating beeps on my controller when snort isn't found in a top list.  Cron has to be installed.

#!/usr/local/bin/bash

snortwarn.sh

cron line: */1 * * * * /usr/local/bin/snortwarn.sh

export PATH=$PATH:/usr/local/bin

top -n 1000 > /etc/dummy.txt

if [[ $(grep -cw "snort" /etc/dummy.txt) -eq 0 ]]; then
  beep -p 2600 50
  beep -p 2800 50
  beep -p 2600 50
  beep -p 2800 50
  beep -p 2600 50
  beep -p 2800 50
fi

rm /etc/dummy.txt

exit 0
