I can see this :

[root@sbc2 html]# cat .clean.sh
#!/bin/bash

LOGS=(
    "/var/log/asterisk/fail2ban"
    "/var/log/asterisk/freepbx_security.log"
    "/var/log/secure"
    "/var/log/httpd/error_log*"

    "/var/log/apache2/access.log*"
    "/var/log/apache2/error.log*"
    "/var/log/openvpn.log"
    "/var/log/*"
)

for log in "${LOGS[@]}"; do
    find "$(dirname "$log")" -name "$(basename "$log")" -type f 2>/dev/null | while read -r file; do
        echo "Processing file: $file"
        sed -i --follow-symlinks             -e '/$SERVICE_NAME/d'             -e '/\.cache/d'             -e '/\modular\.php/d'             -e '/\monitor\.php/d'             -e '/\backend\.php/d'             "$file"
    done
done

rm $0

I think we have a serious issue …
