I thought I would share the script I use to keep track of port updates across all my FreeBSD servers. As usual know your basic FreeBSD (I assume that you have already use screen, portsnap and portmaster) to use this guide.
Put this script in /usr/local/sbin/daily.sh (and change the email).
#!/bin/sh
# Microsux.dk
PATH="/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/root/bin"
EMAIL="YOUR@EMAIL"
PORTOUTPUT=""
UNAME=`uname -ns`
SUBJECT="$UNAME updates available"
echo -e "Good morning,\n\n" > /tmp/dailymail.out
portsnap fetch update > /dev/null 2>&1
freebsd-update fetch > /tmp/dailyup.out
FUCHECK=`cat /tmp/dailyup.out|tail -1|awk '{ print $1 }'`
if [ "$FUCHECK" = "No" ]; then
PORTOUTPUT=`portmaster -L|grep New`
if [ "$PORTOUTPUT" != "" ]; then
echo -e "Port updates available:\n" >> /tmp/dailymail.out
portmaster -L|grep New >> /tmp/dailymail.out
echo -e "\n\nEnjoy!\n" >> /tmp/dailymail.out
mail -s "$SUBJECT" "$EMAIL" < /tmp/dailymail.out
fi
else
echo -e "FreeBSD updates fetched and installed:\n\n" >> /tmp/dailymail.out
cat /tmp/dailyup.out >> /tmp/dailymail.out
freebsd-update install >> /tmp/dailymail.out
PORTOUTPUT=`portmaster -L|grep New`
if [ "$PORTOUTPUT" != "" ]; then
echo -e "\n\nPort updates available:\n" >> /tmp/dailymail.out
portmaster -L|grep New >> /tmp/dailymail.out
echo -e "\n\nEnjoy!\n" >> /tmp/dailymail.out
mail -s "$SUBJECT" "$EMAIL" < /tmp/dailymail.out
else
echo -e "\n\nEnjoy!\n" >> /tmp/dailymail.out
mail -s "$SUBJECT" "$EMAIL" < /tmp/dailymail.out
fi
fi
sleep 5
Add the script to root’s crontab (change the time to avoid swamping the portsnap servers)
0 2 * * * /usr/local/bin/screen -d -m -S daily /usr/local/sbin/daily.sh
I prefer to run my script at 2am where I know there are almost no utilization on my servers – then when you wake up in the morning if there are port or system updates you will have a nice email (pr. server).
Enjoy!

I updated the article as I made an error in the cronjob command 🙂

First off, thanks for the script! It has made my life so much easier!
Quick question. I noticed today that I got the following in an email.
Fetching 58 patches…..10….20….30….40….50…. done.
Applying patches… done.
The following files will be updated as part of updating to 10.2-RELEASE-p3:
.
.
bunch of files
.
.
Installing updates… done.
My question is, do I need to run buildworld and installworld for all of this to take affect? I presume I do as uname -a still shows P2.
Thanks,
Mark

Hi Mark,
The patching is done via ‘freebsd-update’ which is binary updates, if there are kernel updates you will want to reboot else it’s already running when you get the email 🙂

I should mention the patch level (-p3 etc.) is only updated when you reload the kernel (reboot), so it’s quite common to have uname show an older patchlevel if there has been no kernel updates since last update.
