If you’re using Awstats to analyse server logs then the originals can be removed once they’ve been processed. The bash script below removes all of the files found in /var/log/apache2. Running this as a daily cron job ensures that your server doesn’t become bloated.

#!/bin/bash
cd /var/log/apache2
for file in `find .`
do
    if [ -f $file ];
    then
        cat /dev/null > $file
    fi
done
