[SUMMARY] rotating squid logs using logadm

[Brett Lymn]

Last night I posted the message quoted below.  I received the flood of
out of office messages along with a very helpful response from Bill R.
Williams.  Though Bill did not directly give me the answer he pointed out
how the linux logrotate worked with squid, from that I managed to brew
up the right logadm syntax:

squid -C 60 -a '/opt/local/squid/sbin/squid -k rotate; sleep 2; rm -f /logs/squi
d/*.log.0' -c -p 1d -t '$file.%Y%m%d' -z 0 '/logs/squid/{access,cache,store}.log

The logs get copied and truncated.  After that I tell squid to rotate the logs
and remove the redundant copy of the logs.  There is a small window of
log info we don't capture but I am not too concerned about that.

Thanks be to Bill.

Liberal application of the clue-stick goes to:

Come on people, even outlook's lame mail filtering capabilities could have
saved this useless notification.
