Thought this might be helpful for someone else. Gives an non-intrusive little Notification Centre notification to users that have an uptime for longer than x days. Doesn't rely on extension attributes or recon data that could be slightly out of date and not reflect reality.
Leaves a little breadcrumb of uptime in logs for posterity.
#!/bin/sh
##
##
## Purpose: Notifies user if uptime is 2+ days
## Details: Uses Notification Centre, notification (by default) disappears
## after a few seconds. Doesn't rely on potentially out-of-date
## recon/attribute data. No notification if uptime /right now/ is
## less than $minimum_days days.
## Limitations: 10.9+ only.

minimum_days=3 ## single digit integer from 1 -> 9
uptime=$(uptime | egrep "([$minimum_days-9] day|dd day)" | awk '{print $3 " "$4}' | sed 's/,//')
if [ -n "$uptime" ]
then
echo "Uptime: $uptime"
osascript -e 'display notification "" with title "Computer not shut down for '"$uptime"'" subtitle "Consider restarting soon for best performance"'
else
echo "Uptime: < $minimum_days days"
fi
Could be used in conjunction with an extension attribute like this:
#!/bin/sh
uptime=$(uptime | egrep "(d day)" | awk '{print $3}')
if [ "$uptime" == "" ] ; then
echo "<result>0</result>"
else
echo "<result>$uptime</result>"
fi
Cheers,
Matt
