I thought I was pretty handy with awk until I got this one. 
I'm trying to parse a log file where the events could have different delimiters (2 scripts is ok), the errors are spread over multiple lines, and I"m trying to figure out how to not read the same lines that have already been read.
The purpose being that when the script sees something the output will be redirected to mail/snmptrap/etc.
