Thanks for your reply

Both of your suggestions are good but have the same problem.

When the newsyslog command is run the rotate space trigger in
newsyslog.conf may or may not be met.
I need an return code or exit code from the newsyslog command to
check to tell if trigger was met and log really rotated.
Does newsyslog issue such codes and how would I code an csh script
to check for it?

Trying to for see  an DOS attack targeted at consuming all the log
disk space in /var

I would recommend a slightly different approach.  Either of a couple
of different approaches, in fact...

One way to do this would be to use a separate config file for
newsyslog(8) rather than /etc/newsyslog.conf.  Then you run
and use the -f option to have it use your special-purpose
configuration just for rotating this ipfilter log.

The other way would be to do the rotation directly, in your script
which processes the file.  It should only take three or four
in the script.  That would let you more or less eliminate any race
conditions that might leave data out of your logs.
