Squid: list top X referers

If your Squid server logs the referers of its request (i.e.
1. you’ve configured squid-cache with --enable-referer-log before compiling and
2. you’ve included a referer_log /var/log/squid/referer.log in your squid.conf file),
you can easily show top 50 of most popular referers with a simple Bourne shell:
#!/bin/bash

1. this script is ‘top_referers.sh’
2. (c) 2004 Peter Forret – Open Source
   REFERERS=/var/log/squid/referer.log
   OUTPUT=/var/www/html/stats/referer.txt
   MAXLINES=50(
echo REPORT MADE AT `date`
echo =============================
$OUTPUT

Then add it to your crontab:
10 * * * * /(path)/top_referers.sh
and you have an hourly updated stat!
Add a little HTML formatting if you’re aesthetically demanding!
