It is easily customizable without further explanation. However, I think some enhancements should be added (multiple recipients, generic information addition etc.)

#!/bin/bash

# Configuration
SUBJECT="Server repport of `date +%m.%d.%y`"
EMAIL="root@domain.tld"
MSG="/tmp/weekreport"
touch $MSG

# Uptime
echo "Uptime" >> $MSG
echo "`uptime`" >> $MSG
echo "" >> $MSG

# Disk usage
echo "Disk usage" >> $MSG
echo "==========" >> $MSG
echo "" >> $MSG
echo "`df -h`" >> $MSG
echo "" >> $MSG

# Lighty status
echo "Lighttpd" >> $MSG
echo "========" >> $MSG
echo "`/usr/local/etc/rc.d/lighttpd status`" >> $MSG
echo "" >> $MSG

/usr/bin/mail -s "$SUBJECT" "$EMAIL" < $MSG
rm $MSG

1. J’ai enfin fini de mettre en place les serveurs HTTP, DNS, IMAP, SMTP (entre autres) sur mon serveur perso sous FreeBSD. Si il y en a qui sont intéressés, je peux sans soucis écrire un howto et le diffuser ici.
2. J’en profiter pour annoncer mon changement d’adresse email (cf A propos).
