Utile se si vuole automatizzare la gestione dei log, magari attraverso una regola crontab.

# Name: Apache logs archiver (with email notify)
# Description: A simple script that archive logs into an arbitrary directory
# divided by date and time.
# After that it can tar the subdir (and verify it), delete the
# .log files, sign the .tar by md5sum and finally send a mail
# with the urls to download files.
# You can automate the execution of that script using a
# cron rule (monthly, weekly, daily).
#
# Usage: Place this script into your apache’s logdir
# (ex. /var/log/apache2) and run it.
# Set your options in the “configuration” section here.
# Remind: give me +x! (chmod +x apache_log_archiver.sh)
#
# Requires: sendmail, apache*-server, uname, tar, md5sum, whoami, date
