Script to notify if any outdated MacPorts

Updated version here.

-----

Add the script below as a cron job and it'll notify* you if you have any outdated MacPorts.

*Presuming you're configured to have cron job output emailed to you, it'll notify by email. If you have growl installed, it growl at you too. Lastly, it logs to /var/log (which probably requires creating that log file first).

(Updated for recent tweaks.)

#!/bin/bash

# 20071110 mvgfr: check for outdated macports & notify if any - via growl & stdout (emailed when cron'd)
# 20080209 mvgfr: must run sync before, so it can learn about updates!
#                 also added "-H localhost" workaround for growl Leopard bug (ignores some)

# may take awhile; is this an issue?
/opt/local/bin/port sync

potentialOutput=`/opt/local/bin/port outdated`

if [ "$potentialOutput" != "No installed ports are outdated." ] ; then
    echo "$potentialOutput"
    if [ -f /usr/local/bin/growlnotify ]; then
        /usr/local/bin/growlnotify -H localhost -s -m "macports: $potentialOutput"
    fi
fi

echo "`date "+%Y%m%d-%H%M%S"`: $potentialOutput" >> /var/log/port-outdated.log
