I should have been more diligent. The input switch was supposed to be
"-if" IIUC. The "-f" switch is looking for a filename inside the record.

[root slim logs-test]# ausearch -i -if `pwd` -m USER
<no matches>

[root slim logs-test]# ausearch -i -if `pwd`/audit.log.1  -m USER
node=slim type=USER msg=audit(08/17/2009 12:10:52.265:305135) : user
pid=8191 uid=root auid=lcb ses=4172 subj=user_u:user_r:user_t:s0
msg='TEST message: exe=/sbin/auditctl (hostname=?, addr=?,
terminal=pts/18 res=success)'

This is what you want to do right - search inside a directory other
than /var/log/audit with multiple audit logs inside the directory?


   Yes but not search for anything specific. Actually all I want to do is convert the
logs from kernel text to regular notation (ausearch -i) to start with. I like Steve's
idea of doing "service auditd rotate", then moving all the rotated logs to another
directory to run the "ausearch -i" on the logs. This way auditd can keep running and
processing the logs does not effect auditd. So what you did is pretty much what I want
to do with the -if instead of just the -f.
  Thanks Lenny!
