This sounds very useful, Burn.

In an EXECVE message there is something like:

args=2 a0="ls" a1="/etc"

It would be nice if this could be changed to something like

command="ls /etc".

One problem is that the shell script interprets wild cards before auditd
sees the command, and that can lead to long strings. So maybe that
situation could become something like:

something="ls /etc/aaa /etc/bbb /etc/ccc ..."

In most cases a human reader would recognise what is happening.

Also, sometimes the parameters are in hex instead of strings. For
example, when the parameter contains quotes.
