You may need to edit this script to set the locations of the squid and squidGuard binaries, and the blacklist databases.

#
# -- Changed - 15 June 2003
# -- Change
# "squidguard -C domains" to
# "squidguard -C all"
# old way wasn't doing anything useful
#
#Below is the script that I use. You need to edit the first part
#to tell where your squid and squidguard binaries are, and also
#where your squidguard #blacklists are. This has the recent change
#of address for the squidguard.org-supplied blacklists.
#You will need to obtain and install the utility "wget" for this
#script to work. It is available as an RPM for RedHat. WGet is used
#to get the files. You can #use scripted ftp instead, but it's much
#more of a pain and less reliable.

# Script to Update squidguard Blacklists
# Rick@Matthews.net with mods by morris@maynidea.com
# Last updated 05/31/2003
#
# This script downloads blacklists from two sites, merges and
# de-dupes them, then makes local changes (+/-). It does this
# in all of the categories (except porn) using the standard
# squidguard .diff files. The porn directory is handled
# differently, in part because of the large volume of changes.
#
# The user maintains local changes to the porn category in the
# files < domains_diff.local> and <urls_diff.local>. These files
# use the standard squidguard .diff file format:
# +domain_A.com
# -domain_B.com
#
# --------------------------------------------------------------
# Set date format for naming files
DATE=`date +%Y-%m-%d`
YEAR=`date +%Y`
DATETIME=`date +"%a %d %h %Y %T %Z"`
UNIQUEDT=`date +"%Y%m%d%H%M%S"`
