# Sample script to generate a daily SRG report. This script assumes that you
# rotate your squid logfiles on a monthly basis using the srg.monthly
# script provided along with this one. If you have a different scheme you
# may need to modify this script.
#
# This script is designed to be run close after midnight to generate a report
# for the previous day.
# Use a crontab line such as the one below to trigger this script.
# 1 0 * * * proxy /usr/local/sbin/srg.daily
#
# Keeps 1 months (31 days) worth of daily reports in the output directory.
