Some of log rotating example:
Create the script name of /usr/bin/rotateapplog:
vi /usr/bin/rotateapplog

#! /bin/bash

TIMESTAMP=$(date +%Y-%m-%d)
cd /home/app/

cp log/production.log log/production.$TIMESTAMP.log

echo "$TIMESTAMP" > log/production.log

echo "done"

Add script as cron:

1 00 * * * /usr/bin/rotateapplog
