Hey guys,

I'm a bit of a beginner (understatement!) with shell scripting and
seek help! I am setting up our new squid proxy. Its working a treat
and squidGuard is the icing on the cake. But, I am trying to write a
shell script to search through our black list category's for
squidGuard and remove the parsed value;

Scenario:
/some/directory/where/blacklist/is/stored contains about 40-50 folders
called, adult, gambling, banking, warez etc. There is a folder for
each blocking category (and in each folder is two files, urls and
domains, standard stuff for web filtering!)

I have a script to search through
/some/directory/where/blacklist/is/stored and look at each text file
trying to find someblockedsite.com and remove it. This is as far as I
have got:

machine:/blacklistdir# sh ./find_files "blockedsite.com"

find_files is as follows:

#!/bin/bash
rm -f ./found_files
touch ./found_files
find . -exec grep -q "$1" '{}' \; -print >> ./found_files
i=1
while [ $i -le `wc -l ./found_files` ] ; do

    grep -iv $1 $2 > $2.new   ####This is where I am stuck, I have put
$2 but I want to be reading each line of text from found_files?
    rm $2
    mv $2.new $2

done

But I am totally stuck! My questions to this awesome list are: can
someone help my with my script? And, if so, can you explain to me how
you have achieved your solution?

Thanks a lot for reading guys n gals its greatly appreciated.

Regards,

James.
