Programming :: Text Manipulation With Bash For Snort Alert

I have a little problem about string in Snort alerting. I understood about Snort alerting saved in /var/log/snort/alert and Snort will add a new entry if there was a attack from anywhere. Then here's my problem. Because it has a lot of file on it, all I want to do is parse that string in snort alert then make into simply log files with it. I'm getting confused with Snort alert and parse that file.

Here's the simple algorithm; Snort get the alert <- parse the alert with my parameter which I've configured with bash (ip address, dest, kind of attack and time) <- then sent that parse alert into new text (let's called snortsent.txt) <- after ten alerts then clear the text then waiting again until the Snort alert go on -> back to snort alert. Here's the sample of my snort alert: (/var/log/snort/alert)
