Rename hourly rotated web access logs (access.log.1, access.log.2) to include the timestamp for better management of the times

access-log-timestamp.sh

#!/bin/bash

# This script is made to rename default rotated access log files from access.log.1, access.log.2 and 
# so on, to using timestamp instead of auto increment index (to be access.log.2014102009)
#
# USAGE:
# cd LOGS_DIR && ./access-logs-timestamp.sh
