help needed: how to exclude a single file from being audited.

[Vipin Rathor]

Hi Guys,
I've a situation here. I've put a watch on a directory (e.g. -w /etc).
Due to this, every action on files under this directory are being
audited.
Now I want to exclude a single file in that directory (e.g.
/etc/sysconfig/bash-prompt-xterm), how should I do that?
I tried something like this in my exclude list:
-a exclude,never -F path=/etc/sysconfig/bash-prompt-xterm

But got this error:
Only msgtype field can be used with exclude filter

Any idea, how to exclude a single file from a 'watched' directory?

Many thanks.
