Thank you for sharing this Josef, this looks interesting and useful, but
I have a couple of questions, at least based on the example you
provided. The grouping appears to be wrong. Some items in a group share
a common timestamp, others do not and are a mix of other audit events.
Events must share a common second, millisecond, and serial number (and
host when present). I looked at the sed script to see how this was
happening but complex sed syntax is too cryptic to be readable :-( Also,
have you considered using the audit parsing library (auparse) for this
task? It is designed to make parsing audit data easy and robust (and I
dare say more readable and maintainable than sed :-)
