To quickly understand the top 20 web pages from Apache Server log files, a simple shell script is represented as follows:

#!/bin/bash

export PATH="$PATH:/bin:/sbin:/usr/bin:/usr/sbin"
top()
{
for pages in `cut -d' ' -f7 /var/log/httpd/access_log | egrep ".*htm[l]*$|.*index\.php"` do echo "http://www.geego.com.tw$pages" done
}

if `top | sort | uniq -c | sort -nr | head -20 | mail -s 'The top 20 pages' webmaster@geego.com.tw` ; then echo "Top 20 pages sent successfully!"
