====== Log Rotation script ======
Short of using logrotate, below is a quick and simple script to do the same.

===== Script =====
Example of haproxy log rotation
<code bash>
#!/bin/bash
#
LOGDIR=/var/log
LOGFILE=haproxy.log
TARDIR=/data/log
#
LOGDIRFILE=${LOGDIR}/${LOGFILE}
cp $LOGDIRFILE ${TARDIR}/${LOGFILE}.`date +%Y%m%d_%H%M%S`
cat /dev/null > $LOGDIRFILE
exit
</code>

===== crontab entry =====
Include this /etc/crontab
<code>
00 00 * * * root /var/log/logroll
</code>
